The Microbiome – Your Skin’s Greatest Ally!

Here at LUMI, we can’t go five minutes without mentioning the skin’s microbiome. We might talk about it more than any other topic, in fact! The reason we’re so obsessed is simple – maintaining a healthy microbiome is the single best thing you can do for your skin. But what is the skin microbiome, we hear you ask, and why is it so important? Well, let’s find out by diving into all things microbiological!

What Is The Skin Microbiome?

Our skin is home to millions of microorganisms such as bacteria, fungi, and even viruses. We call this tiny but important community of life the microbiome of the skin. These microscopic lifeforms work with the human body and are integral to maintaining healthy skin.

The microbiome is our first line of defence against pathogens and other threats that might endanger our skin or the rest of our body. The layer of microbiota on the skin’s surface forms a physical barrier that prevents unwelcome microbes and substances from reaching the skin itself. When this barrier is broken or is not at its full protective capacity (because our microbiome is out-of-shape), we are more vulnerable to infection and skin degradation from environmental pollutants.

The benefits of the microbiome do not stop there, though! The microbiota on the surface of human skin helps retain moisture, minimise oxidative damage, and help to protect skin from UV radiation. Our immune systems actually communicate with bacteria on our skin’s surface and are used by the body to modulate a range of responses. The microbiome is even involved in repairing damaged skin and healing wounds!

It was discovered at the turn of the 21st century that some bacteria present within the human skin microbiome produce collagen-like proteins that help with skin maintenance. Collagen is the most abundant protein in the body and is vital for skin structure, elasticity, and signaling. Studies have shown that when the skin microbiome is damaged or in a state of serious imbalance (known as dysbiosis), levels of collagen production decrease, which can lead to premature aging and other skin health issues.

The impact of skin dysbiosis is not limited just to collagen production. A damaged or unbalanced microbiome has been shown to affect long-term skin health, as well as increasing the prevalence of diseases such as atopic dermatitis, psoriasis, rosacea, and acne. Research also suggests that the process of skin aging is in part associated with changes in the skin microbiome. Clearly, considering the intertwined nature of microbiome health and diversity with our own wellbeing, the skin’s microbiota cannot be ignored!

How Can I Help My Skin’s Microbiome?

With the microbiome being so essential to skin health, we all face an essential question – how can I maintain a happy, healthy, and diverse microbiome?

The first step, as with everything related to health, is to ensure your diet is varied and nutritious. By eating well, you give your body the resources it needs to properly control itself and make the surface of your skin the perfect environment for a thriving microbiome. Vegetables in particular are vital for skin health, whilst fermented foods such as kefir and sauerkraut help promote the health of microbiota both in the gut and on the surface of the skin.

For more targeted microbiome assistance, consider introducing probiotics and prebiotics to your skin. Probiotics are live microorganisms that are introduced to a microbiome to help repopulate or rebalance the microbial community. Prebiotics are selectively fermented ingredients designed to provide nutrition to and promote the growth of desirable microorganisms. Probiotics and prebiotics taken orally can improve the health of the gut microbiome (and through it, the rest of the body), whilst topically applied prebiotics and probiotics can greatly aid the skin’s microbiome.

All of LUMI’s products are designed with maintaining a healthy skin microbiome in mind. Our three guiding principles are embracing natural ingredients, cutting-edge science, and, most of all, balance. Never is this more important than when considering the needs of the billions of microbiota that call our bodies home.

You can see the results of this thinking in the decisions we make during production. Our cleansers never contain any surfactants or foaming agents, as these have been shown to disrupt the skin barrier and microbiome. In a similar vein, none of our products will ever contain added fragrances or preservatives – both can disrupt your microbiome and create, rather than solve, skin problems. We make liberal use of the polysaccharide hyaluronic acid in lots of LUMI products, which has been shown by several research studies to be the optimal prebiotic for restoring microbiome balance.

We offer a range of products crafted especially to restore and maintain your skin microbiome. There are far too many to list here, but a few highlights that we think you’ll love are the Atopic Smoothie Set, the NAKED Hyaluronic Acid Multiserum, and the 40 & ICONIC Set, all of which contain prebiotics and other helpful ingredients that are perfect for getting your microbiome back to its best!

Ready to take the first steps towards a happier, healthier microbiome? Talk to one of our LUMI skin experts today and find the products most suited to your individual needs – your skin will thank you!

Adapt your skincare routine to your monthly cycle!

The menstrual cycle has a significant influence on women, impacting various aspects of our lives, from our appetites and moods to even changes in our facial skin.

Synchronizing your skincare routine with your monthly cycle provides an opportunity to prevent many skin problems, especially hormonal acne.

We are all unique and experience the changes that come with the cycle differently. Understanding what happens to our bodies and skin during this provides us with the opportunity to address various issues at the right time.

How to build a skincare routine that fulfills the needs of your skin throughout the cycle?

The good news is that you don’t have to rush out to buy new products immediately. Thanks to the versatility of LUMI products, they can be mixed together or blended into “smoothies.” This allows you to adjust your current facial care routine to cater to your skin’s requirements during each stage of the cycle.

Another reason to love LUMI smoothies and get the most out of them! 🤍

The recipe for adjusting smoothies is easy: simply mix LUMI tonics and serums into your favorite cream to make them either thinner or thicker as needed. This process guarantees that your skincare product maintains the desired texture throughout the whole cycle.

👉🏻In this blog post, we will discuss how you might feel during different phases of your cycle and how your skin may appear during these phases. We’ll share ideas on which products you could choose for your smoothies, allowing you to create a skincare routine that suits your preferences while considering the unique aspects of your cycle. Additionally, we’ll help you discover the ideal time to schedule a visit to an esthetician!

You can improve your skin care routine by aligning it with your monthly cycle, making it easier to address your skin concerns.

Your monthly cycle is mainly influenced by three sex hormones:

  • estrogen,
  • progesterone,
  • testosterone.

These hormones fluctuate throughout your cycle, leading to changes in both your well-being and your skin.

👉🏻To better understand your current cycle phase, you can use smartphone apps or a smartwatch, keep a closer look on your calendar and pay closer attention to how you’re feeling.

Menstruation (days 1-6).

Well-being: Your energy levels are low, and you might be experiencing tiredness. You may find yourself preferring solitude to socializing. Take a moment to tune into your body. Allow yourself time to rest and try to remember that it’s not laziness – be kind to yourself.

Skin: It may be more sensitive than usual, so it’s advisable to avoid any painful procedures, such as mechanical cleaning (which might prove challenging for the esthetician to work on), intense peeling, eyebrow plucking, or waxing. Your skin might also feel drier and more irritated, in which case, it will benefit from extra hydration provided by a richer cream or an oil-based serum. When it comes to cleansing, opt for gentle products. Cleanse your skin once a day in the evening.

The main keywords for skincare are moisturizing and nourishing.

TIP: Enhance your routine with LUMI’s oil serums. Choose the one that suits your skin type, and either mix it into your favorite LUMI cream or apply it directly onto your skin.

  1. If you have red or acne-prone skin, the ideal choice is Pimple Stopper. For sensitive skin, it’s better to opt for CBD+ Extra Strong Repair Salve.
  2. If you’re looking to tighten or even out your skin tone, go for the Superbloom Vitamin C Night Serum.
  3. Sunberry’s golden tone and protective formula are the ideal choice for all skin types and conditions.
  4. Because of its rich composition and soothing ingredients, ICONIC overnight peptide treatment is the perfect choice for alleviating dry, irritated, and tense skin during your menstrual week.

Follicular phase (days 6-12).

Well-being: You are filled with increased energy and motivation. Your optimism, communication skills, and cognitive abilities are at their highest. This is also your skin’s golden week as you feel beautiful and radiate in a unique way.

Skin: This is the ideal moment to rejuvenate, regenerate, and pamper your skin. New skin cells are actively developing, making it the perfect opportunity to enhance the skin’s renewal process. Additionally, your pain sensitivity is lower during this period, making it the perfect time to schedule a visit to an esthetician or experiment with new skincare products. Revel in the radiant glow of your skin at its peak!

Enjoy your skins glow!

The main keywords for skincare are stimulating the renewal processes

TIP: Don’t hold back on the usage of skincare products and provide your skin with an extensive pampering session.

  1. Enhance the skin renewal process with a 15-20 minute procedure using a 15% AHA Acid Peel.
  2. Afterward, pamper your skin with Prebiotic HALO Moisturizing Mask.
  3. During this week, consider incorporating Pimple Stopper and Superbloom Vitamin C Night Serum into your skincare routine for their skin cell renewal benefits.

Ovulation (days 13-16).

Well-being: You are energetic and active, yet also sensitive and impulsive. Your libido is higher than usual. Some women may experience mild lower abdominal discomfort during this phase and become more moody.

Skin: Skin becomes oilier as sebum secretion increases, raising the risk of pimples and pustules. This is the time when you can take steps to prevent pimples from appearing before your menstrual cycle begins.

The main keywords for skincare are prevention and cleansing.

TIP:It’s the ideal time to use lightweight makeup and creams! When preparing smoothies, reduce the amount of oil serums and opt for water-based products. Consider adding a tonic to your cream as well. (Superbloom toning mist, Bio-klinik moisture lock toner) or a water based serum like Nudist or Naked hyaluronic acid multiserum.

  1. Opt for products that regulate sebum secretion and have a lightweight consistency. These include the Tundra AHA-BHA Moisturizing Cream, Iconic Well-Aging Treatment, Naked Hyaluronic Acid Multiserum, and Superbloom toning mist.
  2. It’s a good time to either use a 15% AHA acid peel or leave the Tundra or Moisturizing Cleansing Milk on for a longer duration, up to 5 minutes.
  3. When wanting to achieve a tan and glowy look, opt for the No Make-Up Day kit, featuring the clay-based Senses that absorbs excess oil and keeps your skin clean.

Luteal phase (days 17-28).

Well-being: A time when you might begin to experience a decrease in your energy levels, become moodier, and become less inclined to socialize. You may also start craving sweeter and fattier foods. During this phase, your body requires an adequate amount of sleep and time for recovery.

Skin: Just as you become more sensitive and irritable, your skin follows suit. It tends to get oilier and is prone to clogging. You might notice an increase in black and whiteheads. Additionally, during this period, your body can produce more melanin, making freckles and pigment spots more likely to appear than usual. Sensitivity and inflammation are also more prevalent during this time.

The main keywords for skincare are keeping inflammation and sebum secretion under control.

TIP: Take extra care of your skin while being in the sun. Try to avoid skin irritation.

  1. During this week your best friend is the Naked hyaluronic acid multiserum. It helps prevent premenstrual acne, reduces sebum production, has anti-inflammatory properties, prevents the formation of new pigment spots, and diminishes the darkness of existing pigment spots.
  2. When making smoothies, opt for toners and water-based serums. It’s a good time to focus more on cleansing.
  3. Soothe your skin by using the HALO moisture mask.

Irregular menstrual cycle

A 2023 study revealed that an irregular menstrual cycle can harm both the skin’s physiological properties and its microbiota.

Women with irregular menstrual cycles may want to consider paying more attention to moisturizing, protecting, and soothing their skin.

TIP: The Bio-Klinik restorative moisturizer offers essential hydration, balance, protection, and soothing for the skin. Whether you’re dealing with eczema or hormonal acne, Bio-Klinik serves as an excellent solution for both concerns. When combined with Naked hyaluronic acid multiserum, the cream’s anti-inflammatory and moisturizing effects are amplified. Additionally, the probiotics in the cream aid in restoring changes in the skin’s microbiome.

Recipe for smoothies

The main components of a smoothie should be:

  1. a water-based product (tonic, hydrosol, hyaluronic acid serum)
  2. a cream suitable for the skin’s condition.
  3. an oil serum

To create your own unique smoothie recipe, don’t hesitate to reach out to our consultant! You can discover our favorite smoothie recipes in the LUMI sets category.

Many smartphone apps, such as the Flo app, can assist you in tracking your menstrual cycle.

Give it a try and elevate your skincare routine to a more feminine and personalized level!

Mirjam’s Skin Story

“I have always had dry and sensitive skin, along with pigmentation spots and milia. Being nearly 40 years old means that wrinkles, fine lines, and skin flaccidity are more prominent. In other words, I have high expectations for skincare products.

For several years, I used a relatively expensive and highly praised brand’s products. While it did improve my skin issues, they never completely disappeared. Moreover, I had to visit the beautician frequently to prevent my skin from breaking out, roughly every 2-3 months, which became quite costly.

With cautiousness and some reservations, I decided to give the LUMI brand a try. Could all these promises actually be true?! Now, after having used LUMI products for over 2 months, I can confidently say that I will continue using them because my skin has never been in such great condition! And I’m not exaggerating! No more pimples, no milia, and my pigmentation spots have significantly lightened. After washing my face, my skin feels soft and no longer tight like before. When I wake up in the morning, my skin is no longer greasy, and here’s the best part – I have stopped using foundation altogether because I no longer need it. My skin tone is even, and my skin looks healthy.

Don’t panic if you initially face some challenges or notice a temporary decline in your skin’s condition. The ultimate results will be worth it, 100%!”.

Eva-Maria’s Skin Journey

“For almost 21 years of my life, I struggled with dry, broken, and painful skin. Thanks to LUMI, my life has changed forever.

I have a medical condition that makes my skin dry, swollen, and itchy due to allergies to dyes and histamine. To alleviate the symptoms, I have tried various creams from different brands – both over-the-counter and high-end ones. Despite that, I did not opt to use a prescribed hormone cream and instead relied on allergy pills and mositurizers. 

My journey with LUMI began when I started a new job and met Helen, the founder of LUMI. During our first meeting, Helen noticed my skin condition and decided to do some research on my background. Based on that, she recommended creams that suited my skin. It was a humorous but unforgettable start, and little did I know that it would have a significant impact on my life.

From there on I started using the LUMI CBD+ ointment and BIO-KLINIK body cream. Like any other person who has struggled with their skin for years, I started my journey with some doubts. But all of that was for nothing as just a few days later I noticed that the condition of my skin has improved drastically! Already by the end of the week, the minor ulcers and the rash had completely disappeared. At first, I used the combo of creams three/four times a day, but from there on only twice a day. On top of all that, I was also able to stop taking the allergy pills.

By the middle of the second week, I saw something I hadn’t seen in a very long time. My legs and arms were cured – they were healthy and moisturized, without any bumps or sores. Also, I no longer had the itchiness that previously disturbed my sleep and aggravated my skin condition furthermore. To this day my skin is healthy, glowing, and moisturized.

LUMI changed my life, especially my confidence. The summer of 2023 was the first one I could face without feeling embarrassed and insecure – I felt like a big part of my femininity had been restored. I can wear dresses, short-sleeved tops, and skirts without feeling self-conscious about my skin. Finally, I feel good in my own skin!

There are not enough words to show my appreciation, thank you LUMI!”.

Afterglow – Exploring Our Bittersweet Relationship with the Sun

“O, Sunshine! The most precious gold to be found on earth.” 

– Roman Payne

The long-awaited return of sunshine and warm weather is here, filling us all with new energy, ideas, and a sense of spontaneity. Who doesn’t love being bathed in those golden rays, and the luscious tan that surely follows?

Of course, it will be news to no one that those benefits come with considerable risk. UV radiation from the sun can cause a host of issues, ranging from sunburn to premature aging, and even some forms of cancer. The topic is often publicly discussed, but usually from a rather one-sided position, where the dangers of sun exposure are espoused at length and other health and environmental concerns are shunned to the side. Little time is given to exploring the dangers of insufficient exposure to the sun, or the potential damage to our bodies and the planet that sunscreen can cause.

Here at LUMI, we think that’s a problem. As we pride ourselves on our curiosity, we’re keen to find out what’s going on for ourselves and gain a more balanced view of such a multi-layered discussion. So, we decided it’s high time that we delved into the science for ourselves, to find out whether we humans really need to spend all our summertime hidden in the shade and wrapped up from head to toe! Join us as we explore humanity’s bittersweet relationship with the sun.

The dangers of a lack of sunlight

Insufficient exposure to sunlight has become a major public health issue. Research suggests that insufficient sun exposure may be responsible for a startling 340,000 deaths in the United States and 480,000 deaths in Europe per year, leading to increased incidence of a wide range of medical conditions, including several types of cancer, autoimmune diseases, diabetes, Alzheimer’s disease, and even autism.

Vitamin D has long been posited as the major factor behind the benefits of sun exposure, but studies attempting to replicate sun exposure via oral Vitamin D supplements do not show similar preventative effects. These findings suggest that there are innate physiological benefits to humans from sun exposure that cannot be easily gained from other sources.

One such benefit is hypothesized to be UVA radiation increasing the release of nitric oxide from the skin, thereby lowering blood pressure and the risk of cardiovascular disease complications. Even moderate amounts of sun are associated with a reduction in stress, increased mental capacity, and an improved general sense of well-being, as well as aiding in alleviating various skin issues, such as atopic dermatitis and psoriasis.

A 2014 Swedish study found that completely avoiding sunlight exposure significantly increased mortality risk in adults, with a risk factor similar to that of being a regular smoker. Surprisingly, particularly considering prevailing media narratives, the study found no evidence of increased skin cancer risk in those who intentionally tanned compared to those who did not.

Add all of this evidence together and it becomes clear that human bodies, thanks to millions of years of evolutionary processes, need sunlight to optimally function.

The often-ignored drawbacks of sunscreen

The global sunscreen market was estimated to be worth around $8.5 billion in 2019. Every day, tens of millions of people use creams, sprays, and lotions containing UV filters – specific chemicals added to these products to absorb or block radiation from the sun.

Unfortunately, UV filters are not biodegradable, and many sewage treatment plants are ill-equipped to deal with them properly. As a result, UV filters reach natural environments in ever-increasing numbers. Up to 14,000 tons of SPF cream ends up in our oceans every year and is deposited in a variety of aquatic environments, including coral reefs. 

Because UV filters are not biodegradable, the compounds eventually end up inside the bodies of living organisms; originally in microscopic organisms, before moving up through the food chain into every animal and plant in the environment. This can cause a host of problems for animals, including humans, and can be catastrophic for marine life in particular. 

For example, exposure to oxybenzone – a common sunscreen ingredient – is extremely detrimental and potentially fatal to coral reefs, which are home to more than a quarter of worldwide fish species. The destruction of marine environments can have a massive impact on the entire planet – 50-80% of the world’s oxygen is produced by ocean algae.

Substances originating in sunscreen have been detected in human brains, breast milk, and the placenta, proving that they can pass through organic barriers and be absorbed by the body. These substances can remain within our bodies for weeks after sunscreen use and can have substantial detrimental effects, such as disrupting the normal functioning of the endocrine system.

There has been considerable recent controversy about the use of nanotechnology in sunscreen products, particularly those containing titanium oxide. The advantage of nanotechnological sun cream is that it prevents the appearance of a visually unpleasant white layer over the surface of the skin. Unfortunately, the smaller the molecule size of a substance, the greater the risk of it penetrating the body. Several studies have warned of nanoscopic titanium particles’ ability to breach human skin and enter the bloodstream, where they may be activated by UVA radiation and induce DNA mutations that can develop into cancer.

Perhaps surprisingly, after the widespread introduction of sunscreen creams, incident rates of skin cancer actually rose. This has been attributed to sunscreen users relying too much on the protective effect of creams and thereby inadvertently exposing themselves to more UV radiation than previously, as well as sunburn-inhibiting effects of creams stopping skin from reddening, which gives sunscreen users an inaccurate idea of how much sun exposure they have actually had.

It is imperative to be extremely careful when using sunscreen on small children. For babies under six months, it is recommended to instead use hats, protective clothing, and shade from the intense sun rather than using creams of any kind. For children between six months and six years, it is recommended that sunscreen is used sparingly and only on areas that cannot be covered with clothes. It is a common misperception that SPF cream alone is enough to protect children’s skin from sunlight, whilst in reality, other forms of skin care are just as necessary for skin to properly cope with sun exposure and other environmental pollutants.

How does our skin try to protect itself from sun damage?

Over millions of years, human skin has evolved in daily exposure to sunlight, and by doing so, has naturally developed a number of different defense mechanisms to fight the mutagenic effects of solar radiation.

As regular LUMI customers and readers will know, we are in constant awe of the natural marvel that is our skin microbiome. As with so many other dangers we might face, the skin microbiome is our first line of defense against UV radiation. Microorganisms on the surface of the skin react to UV radiation and begin to produce substances and pigments that are protective and beneficial, including melanin, which assists our own internal melanocyte production of the same compounds, meaning they are less overworked, resulting in a reduction in pigmentation spots and a more even, radiant complexion.

As well as the microbiome, our skin has other defense mechanisms to protect against UV radiation. These include the ability to thicken the top layer of skin, the ability to repair DNA, apoptosis (a process of cell death that allows the body to control the total number of cells present), the production of antioxidant enzymes, and skin pigmentation (darkening of the skin).

Our skin’s natural protection against UV radiation is usually sufficient, provided the skin is in good health and is exposed to the sun in moderation. Long-term or excessive exposure to UV radiation can cause the deterioration of skin structure and function – a form of premature skin aging known as photoaging.

Photoaged skin is characterized by fine lines and wrinkles, dryness, hyperkeratosis (increased outer skin layer thickness), pigmentation spots, loose skin from the weakening of connective tissue, and in some cases, precancerous and cancerous lesions. Changes in the skin’s microcirculation (blood flow) can cause permanent dilation of blood vessels, which manifests itself in the form of telangiectasias (dilated intradermal veins) and general skin redness. Photoaging is caused by both UVA and UVB rays.

As a LUMI fan, you can breathe easily, and safely in the knowledge that our products keep the skin’s microbiome in optimal condition. LUMI products are #microbiota respectful, meaning they support and nourish the microorganisms of the skin, which play such an important role in maintaining, supporting, and supplementing your largest organ.

Antioxidants – a therapeutic approach to preventing inflammatory skin damage!

When our skin’s own defense systems are depleted, premature aging of the skin often quickly follows. To fight oxidative damage and protect the skin, LUMI has developed a variety of incredibly effective all-natural antioxidant serums and creams.

Natural antioxidants such as vitamins C and E play a key role in caring for the skin. When these vitamins are mixed together, their beneficial properties are enhanced. In addition to a host of other benefits, the combination of vitamins C and E provide photoprotection, increases collagen synthesis, accelerates the skin’s renewal process, and increases the skin’s resistance to oxidative stress. You can find this powerful pairing in LUMI’s Superbloom Vitamin C Night Serum – by using it before and during the onset of seasonal sun, you’re doing your skin a big favor and providing some of the essential compounds it needs to keep you healthy.

NAKED Hyaluronic Acid Serum is another summer superfood for the skin! In addition to its deep moisturizing effect (dehydrated skin is much more susceptible to burning), the serum contains prebiotics that repopulates the skin microbiome, vitamin B3 to protect skin cells, and algae extract, which redistributes pigmentation in existing hyperpigmentation spots and prevents the formation of new spots. The serum’s fireweed hydrosol also helps increase the skin’s own defenses.

Although UV radiation is the most prominent and aggressive environmental factor to consider when stepping outside, air pollution can also cause significant damage to the skin. Research has shown that urban pollution and UV radiation can have harmful interactions on the surface of the skin. For example, polyaromatic hydrocarbons (found in cigarette smoke) can be activated by UV radiation, causing oxidative stress and damaging both skin cell structure and DNA.

An SPF product alone does not protect against environmental pollution! But never fear, because LUMI has the solution – Sunberry Day Serum, which provides additional natural protection for your skin against solar radiation, blue light, and urban pollution. Milk thistle oil found in the serum protects skin from oxidative stress caused by external environmental factors (including UV radiation), as well as slows down aging and glycation processes at the cellular level. The raspberry seed oil found in Sunberry Day Serum (as well as our La-Laa Baby Oil) offers protection against both UVA and UVB rays at comparable levels to titanium dioxide. Whilst these products cannot protect you from extended bouts of extreme sunlight, e.g. those who are committed to ‘frying in the sun’, these products can give you the opportunity when exposed to moderate sunlight to avoid synthetic sunscreens, including those with carcinogenic ingredients.

The Nudist Hyaluronic Acid Serum, with its pleasant summertime scent, deeply moisturizes skin and offers additional protection against UV radiation thanks to the inclusion of fireweed hydrosol. The lemon balm and mint water used in the product also have a wonderful soothing effect on the skin!

A healthy diet that includes a variety of vitamins and micronutrients helps to restore and maintain your gut microbiome, which in turn helps maintain healthy skin and provide your body additional protection. LUMITEEK nutritional supplements can help support a healthy diet and ensure your body is getting exactly what it needs.

LUMITEEK Cellular Health Selenium is another research-backed option for protecting your skin from UV damage. Studies suggest that orally administered doses of the antioxidant can potentially act as an adjuvant for sunscreen products, increasing their efficacy and protecting the skin from short and long-term UV-induced oxidative damage.

No matter whether the sun is out, probiotics are always a great choice for supporting your body and microbiome. A diverse gut microbiome provides the basis for a diverse skin microbiome, which in turn helps strengthen skin and bolsters its ability to protect against UV radiation.

High SPF creams are NOT the only solution!

Here at LUMI, we believe that the most essential sun-care step is always keeping your skin healthy! By looking after your skin all year round, supporting its microbiome, and keeping it topped up with antioxidants, you’re ensuring that your skin is in the best possible shape to defend itself come the sunny season. When the sun shines, don’t panic – embrace the warmer weather and let sensible decision-making guide your course of action.

LUMI is built on three principles – natural ingredients, top science, and balance in all things. A balanced, moderate amount of sun is good for your body and mind. If you have delicate skin or have to deal with intense sun exposure, we recommend combining antioxidants, maximal hydration, and a natural SPF cream with a moderate amount of non-nano zinc oxide (please choose coral-safe products!). By doing so, you can keep yourself safe, enjoy the most of the warmer months, and do your best for your skin and the planet.

Acne is a complex condition. Often, it can seem a chronic affliction that simply nothing can shift! For so many of us who were promised that acne was simply a part of growing up, it can be disheartening to suffer on with symptoms well into our 30s and even beyond.

It’s natural, then, that searching for acne skincare products can become something of an obsession. Every new product and slogan promises a solution, and everything seems worth a try. Unfortunately, however, advertising slogans cannot be trusted, and it’s important to delve into the composition of products and understand what effect they might have on your skin. You may be doing more harm than good!

Today, we give an overview of the most common acne skincare ingredients that you should avoid, as well as giving you some perfect recommendations for skin-healthy alternatives!

Acne sufferers should be sure to exclude these 5 things from their care routines:

1. Products containing salicylic acid.

One of the most common recommendations for acne-prone skin is to use products containing salicylic acid. However, the use of synthetic salicylic acid in certain cosmetic products has largely been banned due to its endocrine-disrupting effects. Synthetic salicylic acid is still allowed to be used in very small amounts as a preservative in some products, though it is prohibited completely in products intended for children under 3. The allowed percentage of salicylic acid is higher in washable products. You can find salicylic acid in a product’s International Nomenclature Cosmetic Ingredient (INCI) list under its common name Salicylic Acid.

Try instead: LUMI’s Tundra line, which contains willow bark extract, a natural alternative to synthetic salicylic acid that does not have the same harmful effects. Its INCI name is Salix Nigra Bark Extract. It is a strong antioxidant and has skin-soothing, sebum-reducing and mattifying properties.

2. SLS washing gels and excessive face cleansing.

We have spoken about this many times before, but it’s such an important point that it always bears repeating – foaming face washes and over-cleansing the skin should be left in the past! Excessive cleansing makes skin more sensitive and causes increased sebum production. 

Avoid products that contain sodium lauryl sulfate (SLS) in their INCI lists. SLS has been shown to lead to extreme drying of skin and increased pore clogging over time. Whilst removing makeup, dirt, and sebum from the surface of the skin, SLS also washes away the corneocytes between cells, which act in a similar way to cement between bricks. Just like a brick wall with no cement, skin without corneocytes loses much of its rigidity and protective capacity. In general, skin (especially delicate facial skin) does not want to come into contact with any surfactants, which makes it extremely difficult to find a cleansing product on the market today that is actually good for the skin. We have been living in an era of skin over-purification for decades!

Try instead: LUMI Cleansing Milk can be used as a cleansing foam, either during a shower or as part of a morning/evening routine. Oil-based cleansing milks are perfect for removing makeup and dirt from the face whilst also maintaining the natural balance and protective qualities of skin. If you’re still unconvinced, try LUMI cleansing milks for a month and see what your skin says! You will no doubt find yourself left with un-reddened, balanced skin that has found its sense of comfort once more!

3. Fragrances

3000 different substances can be hidden behind the INCI name ‘Fragrance’. You can therefore never be sure which of these substances you are putting on your skin. Both synthetic and natural fragrances increase the risk of allergic reactions to products. Additionally, fragrances are often labelled with the names ‘Aroma’ or ‘Parfum’, the most common components of which include linalool, limonene, farnesol, and geranium. In the best case scenario, you may get away with irritation from these substances; in the worst case, they may disrupt the proper functioning of your endocrine system. When applying essential oils such as these to the skin, one must also be aware of their interaction with the sun. Occasionally, phototoxic reactions may occur.
Fragrances can also disrupt the skin’s microbiome, which can be particularly unhelpful for those already suffering with acne. A balanced microbiome can better limit the reproduction of bad bacteria and thus significantly ease acne symptoms.

Try instead: LUMI creams that never contain added fragrances. Our creams have a natural scent that you can trust. Synthetic fragrances can linger in products for up to 5 years, and can be used to mask other ingredients and confuse the user into believing things are fresher and healthier than they are. LUMI’s natural creams are quite the opposite – they smell fresh because they are fresh! You can read more about the natural scents of LUMI products here.

4. Silicones.

Silicones are not inherently pore-clogging, but the occlusive layer they create locks acne-causing sebum and acne-promoting bacteria in-between the silicone and the skin, which can then increase the frequency of breakouts and pore clogging. Additionally, silicones do not completely wash off the skin because they are hydrophobic compounds.

Try instead: Let your skin breathe freely by choosing LUMI’s silicone-free creams and serums! By doing so, you can be sure that products’ active substances are properly absorbed by the skin and do not get trapped on top of the occlusive layer silicones create.

5. Retinol.

Retinol, sometimes seen under the INCI name Retinyl Palmitate/Retinol, is an extremely popular active ingredient in both anti-ageing and anti-acne skincare products. Despite having some positive effects, it should be noted that retinol causes heightened skin sensitivity, making skin hypersensitive to UV radiation. If UV radiation is the fastest ageing factor for human skin, how can a substance that makes us extra-vulnerable to it keep us young? Sensitive skin also tends to produce more oil, redden more, and become inflamed more easily – all of which can exacerbate the issues of acne-prone skin.

Try instead: LUMI Pimple Stopper and Iconic Well-ageing treatment both use bakuchiol, a natural alternative to retinol that has a similar effect whilst being non-irritating to skin and photostable (can be used during the day, unlike retinol). Bakuchiol helps correct hyperkeratinisation and bacterial growth, whilst also maintaining the lipid balance of skin. It also protects against oxidative stress and prevents the main causes of acne. Bakuchiol, like retinol, also has a strong anti-ageing effect, reducing wrinkles and evening out skin tone, whilst also improving skin elasticity. It’s also suitable for sensitive skin without causing irritation.

In addition to acute active substances, LUMI products contain supporting active substances which intensify and facilitate the absorption and functioning of other active substances.

Of course, with acne, there are a multitude of factors that influence the course and severity of the disease, and we always recommend a holistic and well-researched strategy to treating acne. In this post, we have only had chance to touch on a few specific substances that can actively make your acne situation worse. Avoid them, however, and you’ve already taken a big step towards healing your skin and solving your acne woes!

Helen Hirv is one of the founders of Estonia’s premier natural cosmetics brand, LUMI. Helen came to skincare after her child was struggling with atopic dermatitis.

What to look for in skincare?

Helen: “Always keep in mind the principle of less is more. The product must be pure in its composition, and usually just one product is enough – either a bath oil or a base cream. The worst irritants and allergens are fragrances and preservatives. I have never washed a small baby with a body wash or liquid soap – most of these products only serve to dry the skin out and destroy the child’s skin’s protective layer. The moisturising oil or base cream must be properly absorbed into the skin – do not rush to clothe your child after application.

La-Laa Caressing Baby Oil softens, soothes and is fragrance free; composed of food-grade quality ingredients with organic certification.


“In the case of milder eczema, moisturising with vegetable oils is often enough – there is no need for more complex formulations. It is important to monitor your child and assess how severe the eczema is. There is a big difference in the types of intervention necessary for skin that is simply rough or is fully inflamed, for example. From my experiences with my own two children, slight roughness or redness of the skin can often be effectively treated with basic skincare. However, as with any condition, dermatitis treatment requires us to consider and address the needs of the whole body, not just an affected area.

Is Skincare Alone Enough?

“Skincare is an important part of treating dermatitis, but is essentially only dealing with the consequences of the condition. It’s vital to find out the circumstances that trigger dermatitis symptoms. In general, in summer, dermatitis is mostly alleviated or disappears entirely, thanks to sun and seawater. The disease can be much more active in spring, autumn and winter – particularly around Christmas time, where bad weather combines with children eating lots of sweets and high-sugar fruits, etc.”

“In the case of caring for my own children, I try to ensure that all products used at home – from cleaning products to body washes – must also be pure compositions that are as free of additives as possible. I use as few as possible, and don’t have shelves of products each only catering to very specific niches. For example, I use soda a lot – a very basic yet useful cleaner. We also eat home-grown or organic food as much as possible, and try to avoid store-bought fruit. Additionally, we supplement all of this by taking vitamin D and probiotics, as the gut microbiome affects the entire body’s health.”

“I strongly recommend consuming Omega fatty acidshemp oil is taken daily in our family. I often see people afraid to give vegetable oils to their kids, as if it is something dangerous, yet never question the medicines they regularly use with them. My children have been consuming hemp oil since they were babies, because I know just how beneficial it can be – helping with digestion, skin conditions, child development, and much more.

What else should I keep in mind?

“Continual monitoring of your child is key – keeping a diary can be extremely helpful, as atopic dermatitis is a very individualised disease. Avoid external irritants as best you can, and avoid food additives and processed foods. Sometimes, it’s possible that small children are not actually reacting to additives, but are simply adapting to new types of food. For example, some babies cannot eat carrots without skin irritation until at least a year old.”

“Focus on your child, not how others are doing. Be alert to their wants, needs and reactions. If some things are not working, do not push your child’s body to accept them, but rather give it time. If a child’s skin is itchy, don’t scratch it; instead, pat it or gently massage vegetable oil into the affected area – it will have a much less damaging effect on the skin.”

Helen’s Reminders

Probiotics and hemp oil:

“Number one in my dermatitis skincare kit. Both are supported by a wealth of research. It has been shown that the microbiome of allergy sufferers is significantly less diverse than non-sufferers, and since modern humans have already lost a significant amount of their bacterial diversity compared to our ancestors, probiotics can be beneficial for everyone. There is nothing to lose, whilst results can often be astonishingly effective – especially for babies born via caesarean section.”

“Hemp oil provides us with Omega-3, which approximately 85% of people are lacking, and supports many bodily functions. Why cannabis? Because hemp has the perfect ratio of omega acids for humans, and also contains gamma linolenic acid (GLA), which is great for fighting skin problems.

Probiotics can be beneficial for everyone.


Home cleaning:

“For cleaning my house, I only use soda, citric acid and vinegar, and try to avoid taking home anything with excess additives. I do my laundry with an eco-friendly liquid detergent and I always research ingredients before buying products; I use liquid products with simple compositions that are as natural as possible, and always fragrance-free. I do not use powders of any kind, and won’t go near questionable preservatives (such as anything containing methylisothiazolinone). Sometimes you’ll find such products labelled eco-friendly, so it pays to be attentive to ingredients labels. Fragranced products can be recognised by parfum/fragrance on the bottle, or words such as linalool, limonene, etc. This is also how I can tell if skincare products are fragranced. Added chemicals and synthetic fragrances are often the root cause of allergic reactions. Finding the reason for your flare-up is imperative to properly solving the issue.”

Find the reason:

“When you are aware of food allergies or intolerances, allergies to household chemicals, etc., your chances of controlling the problem are much greater. In milder cases, a good cream can relieve atopic dermatitis symptoms, but it is still important to identify the root cause of the issue. Visiting a doctor is always a good idea, but you can also do a lot yourself through observation, experimenting, and using a food diary. Try to think when the problem started – perhaps after introducing new foods, medicines or vaccinations, beginning nursery or school, etc. Something new in the child’s life may have caused this overreaction of their immune system.”


“Stress can be a big factor in atopic dermatitis manifesting, and stressors on the body can be wide-ranging. According to research, about 30% of skin diseases have a psychological component to them; after all, the skin is an emotional organ, too.”


“Try to provide organic foods for children, and avoid additives (e-numbers), sugar, wheat, and dairy products. The composition of food should be simple and nutritious (things like ready-made meals often are not). Ensure your child’s diet contains plenty of prebiotics or food for the good bacteria in the gut (e.g. green vegetables). We put a special emphasis on garden vegetables and fruit – local berries, for example, are full of essential nutrients.
“Of course, reactions to vegetables and other healthy foods are also possible – there will always be certain people who cannot eat certain things. Food is such a broad topic that it is impossible to do it justice in so few words, but avoiding processed foods that promote inflammation is always going to be of benefit.

“I have come across cases where a parent has observed and tried many things, but ultimately the root of the problem often comes down to wheat or milk. For example, after eating a pancake, the child’s face may have been very red for several days. It can be difficult to spot signs right away, but you will become better the more you try. If there are several irritants at work the situation can become more complicated, as eliminating one may not cause a visible improvement if other substances are still causing symptoms.”

Processed foods are generally unsuitable for a healthy lifestyle because they contain lots of additives, have been sitting for a long time losing nutrients, and myriad other reasons. Oriental teachings recommend eating stewed food. Particularly in winter, try to favour warm stewed meals over raw food, so as not to add moisture to the intestines or reduce their temperature. A particularly effective body restorer is a mild homemade bone broth (this can also be great for adults, as it restores the collagen reserves responsible for skin elasticity).

“We often hear it said that because an allergy test has come back clean, someone must be fine to eat absolutely everything. However, in reality, a food intolerance test can give completely different results. You may still find that if you adjust a child’s diet properly, positive results will follow. The diet must be strictly adhered to when it comes to potential intolerances, though. It is not enough to not drink milk at home or only at nursery, etc. Additionally, it is important to monitor whether there are other health concerns that may factor into the issue – diarrhoea or constipation, abdominal pain, long or intense periods of illness.”


“Zinc helps greatly as a dietary supplement, as it supports the immune system and cleanses the body. In the case of breastfed babies, it’s usually enough for the mother to take high-quality zinc on her own. Since it is increasingly difficult to get the requisite levels of minerals and vitamins from food these days, babies can also struggle to inherit enough of these substances from their mothers. Children may also benefit from supplemental digestive enzymes.”

Highly reactive and absorbable, zinc diglycinate is an important mineral for the functioning of the whole body.


Children’s clothes

“It is advised to choose eco-cotton if possible, as well as eco or additive-free nappies. Silk and wool (or blends including them) are also fine, though wool may not be suitable for everyone.”

Bath and pool

“These would be minimum recommendations, with the pool being a ‘no’ in any case. Applying cream is not a solution for repeated irritation. I washed my children just with clean water until quite late on – babies do not need liquid soaps or similar under any circumstances. Both adults and children can use hemp oil and Epsom salt in bath water, for example. With shower products (and the same with creams), make sure you use clean, pure products – petroleum products, preservatives, fragrances and strong surfactants destroy the skin’s microflora, rather than supporting it. As a result, the skin’s protective barrier becomes weaker. The sun and sea water are great saviours – even one day at the beach can be transformative. In winter, when the weather is at its harshest, a sunny beach holiday will only do you good.

“Finally – if the microbiome is strong, the mind is calm, and the body can handle allergens on its own. The key word is B A L A N C E.

Skincare recommendations for a child with atopic dermatitis:

  • Instead of a bath, try a quick and lukewarm shower. Avoid foaming soaps. If you wish, add LUMI La-Laa Caressing Baby Oil whilst bathing or apply afterward onto damp skin. The oil has a certified organic formula that makes babies’ skin silky soft. It is also suitable for removing baby dandruff or softening crusty areas of skin.
  • In the case of atopic dermatitis, it is important to remember that if skin is very red or broken, any water-based product can sting the child and make skin redder. In such cases, we recommend applying anhydrous products, such as LUMI CBD+ healing salve, for the first few days. If redness recedes, you may switch to a LUMI Bio-Klinik cream. Read more about our treatment combo for children’s atopic dermatitis here.
  • When cold weather arrives, you may notice irritation on your children’s hands or a harsh dryness. Children often do not dry their hands properly after washing them, which can cause their skin to become fragile and not function properly. LUMI Arctic Hand Cream creates a protective layer over the skin that will help remedy and prevent such situations.
  • We recommended giving your child 2 tablespoons of mild hemp seed oil daily. Our favourite is PĒLL mild hemp seed oil. You may be surprised at the gentle taste and how happy your children are to take it!

“My 3-year-old daughter developed red, dry patches on her legs. At first, there were a few that disappeared by themselves, but as time went on, more of them started to appear and the situation worsened. We received a diagnosis from the doctor – atopic dermatitis. The doctor immediately recommended to start using hormone ointment, but my mother’s heart did not allow me to apply hormone ointment for my child as the first option.

I decided beforehand to delve deeper into the disease and try to find alternatives. As a first step, we gave up strawberries, sweets and juices from our dining table. On the recommendation of the specialists, we also started using a moisturizing cream to reduce the itchiness and speed up the healing of the skin. The chosen cream was LUMI’s Bio-Klinik Moisture-Lock Body Cream. In the past, I have used various LUMI facial care products on myself, which I really, really liked. In addition to being effective, these products are also 100% natural!

We used the cream twice a day and after two weeks we could already see signs of improvement. After four weeks of use, the red dermatitis spots were gone! Atopic dermatitis is characterized by rapid resolution with proper care, but the result may not be long-lasting. So we have been using the cream once a day until now, and the signs of dermatitis have not returned. I wholeheartedly recommend to everyone to try LUMI’s Bio-Klinik Body Cream before taking medication – Your body will thank you!” – Little Nora’s mother

Our bodies are constantly sending us signals. You might ignore these warnings, passing them off as your own individual quirks. But if you start to research these symptoms, which by themselves seem so disparate, you may find that all signs lead to a deficiency in one specific substance – zinc!

If you have noticed tiny white spots on your nails, excessive hair loss, constant diarrhoea, wounds that heal slowly, eyes that do not adapt to darkness, and skin constantly irritated by reddened patches of dermatitis or acne, then your body may be signalling to you that you have a zinc deficiency.

According to the World Health Organization (WHO), about 30% of the world’s population is zinc deficient.

The most common cause of zinc deficiency is chemical farming, which depletes the natural zinc content of crops, and subsequently the food we eat. Zinc deficiencies can also be caused by the use of certain medications, malabsorption (a digestive disorder that prevents the absorption of nutrients), and an imbalanced diet. Since excess zinc is not stored in our body, it is important to regularly consume foods that are high in zinc or take zinc supplements.

Zinc is the most abundant intracellular metal in the body after iron. It is found everywhere in the body, with 85% stored in muscles and bones, 11% in the skin and liver, and the rest in other bodily tissues.


Our greatest physiological need for zinc occurs as we go through puberty, coinciding with a period of rapid bone growth. Newborn infants, children, pregnant and lactating women, and the elderly also need more zinc. Regular alcohol drinkers, vegans, and those suffering from leaky gut syndrome all have a heightened risk of having a zinc deficiency.

Symptoms of a zinc deficiency may include:

  • Loss of appetite
  • Irritability
  • General hair loss
  • Rough and dry skin
  • Slow wound healing
  • Poor sense of taste and smell
  • Diarrhoea and nausea

Zinc rich foods include:

  • Red meat and poultry.
  • Beans, nuts, and whole grains.
  • Dairy products such as yoghurt, milk and cheese.
  • Seafood such as crab, lobster and oysters – in fact, oysters contain more zinc per serving than any other food!

Zinc absorption occurs in the duodenum (the first part of the small intestine, connected to the stomach). Citric acid increases zinc absorption, whilst iron, fibre and phytic acid have the opposite effect.

Zinc and skin

The skin is our largest organ and has a huge physiological need for nutrients. Our bodies constantly repair and renew skin, and it is vital to understand the importance of nutrition when it comes to overall skin health. If you want healthy skin, you must nourish and protect it – from outside and in!

Zinc is an important trace element that is necessary for skin to function normally. It is vital for cell renewal, collagen formation, and wound and tissue repair. Zinc is also an important antioxidant.

Even a mild zinc deficiency can impair collagen production, fatty acid metabolism (including Omega-3), and wound healing.


Zinc is necessary for the formation of keratin and the skin’s structural protein, collagen. Collagen in the skin is produced by zinc-dependent enzymes. Zinc is not only vital for enzymes producing skin collagen types 1 and 3, but also for collagen cross-linking, which gives the protein strength and stability.

Studies have shown that a decrease in zinc leads directly to a decrease in our bodies’ total collagen levels. Our skin contains a high content of zinc – almost 5% – which is mainly located in the epidermis. Because of this, even a slight zinc deficiency can quickly manifest itself with noticeable symptoms such as skin roughness and slow wound healing. Zinc is our skin’s 24-hour repair technician.

Zinc deficiency and skin problems

Zinc is recommended as a dietary supplement for acne, rosacea and dermatitis. This is because it reduces keratinocyte activity and our inflammatory response to bacteria, as well as strengthening immunity.

Given that the overuse of antibiotics is considered by many to be a global health emergency, the role zinc can play in addressing skincare problems should not be ignored. Studies on the combined use of zinc and vitamin B3 (nicotinamide) to treat inflammatory skin problems such as acne are particularly promising. The treatment has been shown to have an anti-inflammatory effect on the skin and a bacteriostatic effect against propionibacterium acnes, as well as reducing excessive sebum secretion.

Zinc and hormones

Zinc plays an important role in the endocrine system, supporting thyroid hormones and helping the body cope better with reactions to stress. Zinc regulates menstrual cycles in women, promotes ovulation, and can reduce premenstrual discomfort. It can also help to balance the production of sex hormones, including testosterone and prolactin. Women with polycystic ovaries (and associated hair loss), acne, or hirsutism are frequently found to be zinc deficient and can benefit from zinc supplementation.

Zinc and the human papillomavirus (HPV)

Given zinc’s abilities to facilitate immune system, tissue and wound healing, the potential effects of zinc on post-papillomavirus healing have also been studied. In April 2022, an article published in the Asian Pacific Journal of Cancer Prevention detailed a recent study where 80 women with a positive HPV PAP test and abnormal changes in cervix cells (ASCUS or LISL) were given zinc supplements for 3 months. The results of the study showed that oral zinc consumption accelerates the disappearance of the HPV virus and the healing of existing cervical lesions.

Zinc and children

A zinc deficiency can occur even in an adult with a varied diet, so it should come as no surprise to learn that children, particularly those with selective eating habits, can be susceptible to zinc deficiencies. Zinc helps children’s immune system better cope with frequent viral diseases, supports age-appropriate growth, and helps with cognitive development. Zinc can also help in combating common childhood skin problems.

The most common signs of zinc deficiency in children are:

  • Low-functioning immune system and frequent upper respiratory tract infections
  • Slow growth rate
  • Slow cognitive development
  • Poor appetite
  • Diarrhoea
  • Difficulty concentrating or being easily distracted
  • Skin issues and slow wound healing

An individual’s daily requirement of zinc will depend on their age and body condition. It is recommended to consult your family doctor before administering food supplements to children. LUMITEEK offers zinc in the form of zinc diglycinate, which has been shown to have excellent absorption capacity. The daily dose contains 25mg of zinc. Take 1 capsule a day after a meal, as a course of 3-6 months (as needed).

How to cleanse your face

Let’s face it: people have made many mistakes when using cosmetic products in recent decades. As a result, they have damaged their skin instead of supporting it.

Cleaning your face plays an essential role in skincare routine. Let’s take a look at the ingredients we should avoid and point out the most effective and safe methods to clean our skin.

5 tips for healthier skincare

We all wish for healthy, vibrant skin. When looking at ingredients, however, it can feel as if you need a degree in biochemistry to make sense of it all. What do you need, and what can be left on the shelf? We bring you five tips to help you make better skincare decisions.

1. Ceramides and useful fatty acids

Ceramides are like cement that holds together the body’s protective wall of skin cells. They are essential in maintaining your skin’s protective qualities and keeping moisture inside the body. Unfortunately, the amount of ceramides in our skin decreases with age. The amount of polyunsaturated fatty acids that give elasticity and mobility to ceramides also decreases. They are replaced by saturated fatty acids, causing stiffness of the skin.

How to get more high-quality ceramides with the help of skincare products? Ceramides are lipids (fats) and can be added to products in synthetic form, as plant extracts, or using high-ceramide vegetable oils. Here at LUMI, we prefer the latter method. Hemp oil contains several ceramides, omega-3, and omega-6 polyunsaturated fatty acids that the human body cannot produce. We avoid excess energy consumption and over-processing raw materials while ensuring our products are efficient. Ceramides are great for addressing extremely sensitive, extremely dry, or atopic skin.

Most LUMI products have hemp oil in them.


2. Microbiota of balanced skin

Recent studies have shown that the millions of bacteria living on the surface of the skin play a vital role in skin health. The collection of microorganisms is the first line of defence against environmental damage to the skin. The balance of this ecosystem, involving active cooperation between our immune system and beneficial bacteria, is crucial for maintaining healthy and youthful skin. Numerous studies have found a direct link between an imbalanced bacterial ecosystem and skin issues.

How to keep the skin`s microbiota healthy and vital?

  1. Keep in mind, less is more! Maintain an optimal skincare regimen and avoid extremes. Avoid using too many different products, toxic ingredients, and extreme treatments like mechanical exfoliation. For example, do not mechanically exfoliate your skin!
  2. Use hermetically sealed cosmetics in pump bottles – they do not need strong preservatives.
  3. Avoid products that have fragrances and alcohol in them.


3. AHA-BHA acids and lactic acid

Lactic acid helps maintain hyaluronic acid levels in the body. It stimulates collagen and elastin, making skin more viable and firm. By gently exfoliating the aged surface layer of our skin, lactic acid promotes skin renewal and a more even skin tone. Lactic acid helps to maintain the correct, slightly acidic pH level, which is necessary for a balanced skin ecosystem.

Be careful with AHA-BHA acids! Excessive AHA-BHA exfoliation can damage the skin barrier rather than balancing your skin. It is also vital that AHA-BHA acids are applied to the skin alongside lipids. All LUMI products are formulated with mild amounts of AHA-BHA and include beneficial omega fatty acids.


4. Hyaluronic acid

Hyaluronic acid binds water to the skin, providing moisture and elasticity. When hyaluronic acid is mixed with water in a laboratory, the resulting substance has a gel-like, springy consistency. Children’s skin is also flexible and elastic. Unfortunately, as people get older, hyaluronic acid levels decrease, skin dries out, and forms wrinkles. Thankfully, it’s possible to increase levels of hyaluronic acid in the body through skin care, provided the molecules used are of the correct size.

At LUMI, we use various sizes of hyaluronic acid molecules to ensure deep and extensive hydration of the skin’s different layers. We use post-biotic hyaluronic acid produced as a result of bacterial life activity. This vital ingredient is included in all our products for hands, body and face.


5. Antioxidants

Antioxidants neutralise free radicals in the body’s tissues. Normal body processes produce free radicals, and some perform vital signalling functions. However, environmental factors such as solar radiation, pollution and stress can intensify the production of free radicals.

Free radicals are like solitary particles that circulate through tissues and seek bonds. These particles can bond with vital molecules, such as DNA or collagen (which gives elasticity to the skin), causing them to break down. Fortunately, our bodies have a pretty effective system that uses antioxidants to control the entire process.

It is recommended to get additional antioxidants through food and skincare. Vitamins A, C, and E are all effective antioxidants; none is favoured over the others. A combination of these works best in skincare.

Body and hands

The season of dry and fragile skin is here – indoor air is dry and outdoor conditions are harsh. Moisturizers protect the skin from environmental factors by strengthening the skin barrier. Your body and hands need creams and treatments according to your skin type, just as your face does. Unfortunately, choosing the right cream can be challenging – there are numerous lotions and creams available today, and some of them have ingredients that are difficult to understand.

LUMI moisturizers have been developed in cooperation with Tallinn University of Technology and the University of Tartu.

Our moisturizers are based on Estonian 100% organic hemp seed oil and they do not contain synthetic fragrances, silicone oils, petroleum products, or preservatives. Hemp oil can moisturize perfectly, and so can LUMI creams!

We will help you learn about the differences between LUMI creams, lotions, and oils. Choose your favourite body moisturizer for the season according to your skin type – it is easy!

For the body

BIO-KLINIK soothing and moisturizing body cream

BIO-KLINIK moisture-lock body cream will hydrate your body for up to 48 hours. The cream calms your skin, helps to regenerate tissues, and protects against irritations. The cream is suitable for atopic, dry, itchy, scaly, reddish, and extremely sensitive skin. Problematic skin with dermatitis and other skin issues will love this cream as well.

Nourishing body oil

Our best-selling and award-winning revitalizing body oil was one of our very first products. It includes hemp seed oil and urea, which helps the oil to absorb. Essential oils activate lymphatic circulation and are excellent for tightening facial skin. Use the oil after a shower or mix a few pumps of it into your bath water and enjoy the softness of your healthy skin.

Revitalizing body lotion

LUMI deeply moisturizing body treatment targets skin issues systemically, entering different layers of the skin. Camellia oil and hyaluronic acid can penetrate deep – they add elasticity to the skin and keep it hydrated with the help of Peucedanum Ostruthium and lactic acid. Hemp seed oil improves the skin’s natural protective barrier and prevents dehydration. Shea butter creates a protective layer on the outer layer of the skin, the epidermis.

The lotion is suitable for sensitive skin. Absorbs fast, hydrates for a very long period, and makes the skin silky. This body lotion is perfect for dry and very sensitive skin.
