Publié le 03-03-2022 et mis à jour le 17-10-2024
You have probably already heard about the microbiota and more specifically the gut microbiota?
Did you know that there are others? Indeed, the microbiota is defined as a collection of non-pathogenic bacteria or microorganisms.
But then, what is the role of the microbiota, and in particular the role of the microbiota on the skin?
It is located in several places: in the intestines, in the mouth, at the level of the vaginal mucous membranes, in the lungs, and on the skin.
The skin flora will be of interest to us in this article. You will be able to discover why you get unsightly pimples that appear at certain times, for example, and find out about the most effective dietary supplements for the skin.

Our intestinal microbiota is composed of so-called “dominant” species such as Clostridium, Eubacterium, Bifidobacterium which are beneficial bacteria for our health. They contribute to intestinal comfort, for example.
It also consists of species called "rare and transient" such as Streptococcus, Escherichia Coli which are bacteria that do not remain in the body as their name indicates. They are generally pathogenic.
The colonization of the microbiota occurs in several stages: from birth we have the mother's vaginal microbiota, then it occurs through breastfeeding and afterwards the bacteria diversify.
Its composition varies according to several factors such as diet, lifestyle, and medication treatments that will alter the good bacteria.
I. Microbiota and skin
1. What is the role of the microbiota?
Intestinal Flora
The intestinal flora plays several essential roles for the proper functioning of the body:
- Immune system: it acts as a protective barrier, preserving the non-pathogenic bacteria of the microbiota while opposing external pathogenic bacteria. This role is crucial for maintaining a microbial balance favorable to overall health.
- Protection: the intestinal flora releases mucus to protect the intestinal cells. This mucous layer acts as a defense by preventing pathogens from penetrating the intestinal walls and causing infections.
- Metabolic: it is involved in digestion, notably thanks to the bacteria in the colon which are equipped with enzymes capable of breaking down complex carbohydrates and other nutrients to use them as their energy substrate. This allows for better nutrient absorption and a more efficient metabolism.
- Neurological: according to various hypotheses, the microbiota could reduce the symptoms of autism and neurodegeneration. There is a bidirectional communication between the gut and the brain, often called the gut-brain axis, which could play a role in regulating mood and cognitive functions.
Link between the gut microbiota and the dermis
The gut microbiota not only plays a crucial role in digestion and immunity. It also has a significant influence on skin health. Indeed, a healthy gut promotes radiant skin.
Intestinal bacteria produce beneficial metabolites that can reduce systemic inflammation, a key factor in many skin conditions such as acne and eczema.
2. Role of the skin flora
The skin flora also has several essential roles:
- Protection: thanks to non-pathogenic microorganisms that protect our skin. They are invisible to the naked eye but play a major role in defending against external pathogens.
- Immune system: the skin flora acts as an immune system regulator by protecting the host from certain internal aggressions such as inflammation, which is responsible for infections and cellular aging. It thus helps to maintain healthy and resilient skin.
The skin serves as a protective barrier against the external environment: daily aggressions, temperature changes (summer, spring, autumn, winter), stress, lifestyle, pollution.
Our skin is a full-fledged organ; it is a so-called "excretory" organ, meaning it plays a role in fighting toxins. The skin is made up of three layers with different compositions: the hypodermis, the dermis where collagen fibers can be found, for example, and the epidermis, the most superficial layer.
The skin flora is composed of different species of bacteria that feed on sebum, proteins, lipids, and dead cells.
This bacterial diversity varies according to several factors such as vaginal or cesarean birth, breastfeeding, diet, age, puberty, old age, sex, genetics, climate, lifestyle, and the individual's immune status.
The skin is composed of dominant species such as staphylococci and coryneform bacteria, but also transient species. The composition of the skin varies depending on its characteristics. For example, Malassezia yeasts are mainly found on oily skin, necessary for their survival. Transient microorganisms can cause skin disorders in case of imbalance.
Evolution and maintenance of the skin flora
The composition of the skin flora evolves over time and can be influenced by various environmental and personal factors.
Excessive skin cleansing, the use of harsh cosmetic products, and hormonal variations can disrupt this fragile balance.
It is therefore essential to choose gentle and suitable skincare products, as well as to maintain a balanced diet rich in nutrients beneficial for the skin.
Finally, it is important to note that the diversity and richness of microorganisms on our skin are essential for healthy and radiant skin. A balanced skin microbiota helps prevent infections, maintain hydration, and provide effective protection against external aggressions.
II. Microbiota and skin: Impact of the microbiota on the skin
1. Influence of the intestinal flora on the dermis
When the microbiota is imbalanced, it is called dysbiosis. This means that our body is no longer in symbiosis with the bacteria that compose it.
A deregulation can promote the onset of certain pathologies such as inflammatory bowel diseases, diabetes, or skin inflammation like eczema, psoriasis, or acne.
This sudden appearance of pimples mainly affects the face but in some cases can be found on the back, neck, and chest area.
This imbalance can be caused by the various factors mentioned earlier in the article but not only. Indeed, hygiene can have an impact on our skin, excessive hygiene, the use of unsuitable cosmetics that deteriorate the protective lipid film and serve as a perfect breeding ground for pathogenic bacteria. They reduce the barrier function and the skin's pH, which becomes alkaline and therefore no longer effectively protects against microbial infections.
The link between diet and gut flora
The quality of the diet plays an essential role in the balance of the gut microbiota. A diet rich in fiber, fruits, and vegetables promotes the growth of good bacteria.
On the other hand, a diet too rich in sugar and saturated fats can disrupt this flora, leading to effects on the skin. Fermented foods like yogurt and kefir are excellent sources of probiotics, helping to maintain a healthy microbiota.
The importance of prebiotics and probiotics
Prebiotics, found in foods like garlic, onion, and asparagus, feed the good bacteria of the microbiota.
Probiotics, for their part, directly provide beneficial bacterial strains. A balanced combination of these two types of foods can greatly improve skin condition by reducing inflammation and promoting better hydration.
2. Influence of the skin flora
The skin flora plays a crucial role in protecting the skin against external aggressions.
A balanced skin microbiota helps maintain the integrity of the skin barrier, thereby preventing the penetration of pathogens and the loss of hydration.
In case of imbalance, skin conditions such as acne, eczema, and psoriasis may appear. The diversity and richness of microorganisms on the skin are essential for healthy and radiant skin.
Factors influencing the skin flora
Several factors can influence the composition of the skin flora, including climate, lifestyle, and even the skincare products used. For example, humid environments promote the proliferation of certain bacteria and yeasts, while dry climates can alter the skin barrier and promote irritations. Using gentle products suited to one's skin type is essential to maintain a balanced microbiota.
Role of hydration in skin balance
Hydration plays an essential role in the balance of the skin flora. Well-hydrated skin is less likely to crack and allow the entry of pathogens. Moisturizing creams containing ingredients like hyaluronic acid can help retain moisture and maintain a healthy microbiota. Additionally, drinking enough water each day is crucial for radiant and well-protected skin.
III. Dietary supplements beneficial to the microbiota
1. Dietary supplements for intestinal flora
To enrich your microbiota, it is essential to adapt your diet by consuming products rich in prebiotics and probiotics such as garlic, onion, as well as fruits and vegetables that are rich in fiber, vitamins, and minerals.
Spices and aromatic herbs, such as turmeric and ginger, have anti-inflammatory properties and help destroy pathogenic bacteria.
Diversify your diet as well as that of your children to stimulate the growth of good bacteria. If diet alone is not enough, there are specific dietary supplements to address imbalances in the microbiota responsible for bloated stomach, acne, and other digestive disorders.
Here are our solutions for the microbiota and bloated stomach, as well as to optimize the protective barrier of your skin. Dietary supplements adapted and perfectly addressing the body's issues.
Our Absolu Probiopure is an innovative and powerful formula. It is composed of a combination of 5 strains of lactic ferments closest to the human intestinal microbiota, highly concentrated and contained in a gastro-resistant capsule to ensure maximum absorption. This means that the active ingredients contained in the vegetable capsule will not be altered during their passage from the stomach to the intestine. This allows you to benefit from all the advantages of the active ingredients.
We recommend undergoing a treatment over several months to allow the good bacteria to colonize your intestine and address the various issues you are facing. This will promote good digestion, proper nutrient absorption, and significantly reduce intestinal disorders and feelings of bloating.
2. Dietary supplements for the skin flora
For the skin flora, it is just as important to choose high-quality dietary supplements. Our Skin Detox is a perfect formula to detoxify your skin.
Indeed, the skin is the mirror of our emotions and therefore, in case of imbalance, the appearance of small imperfections is instantaneous. That is why at D-LAB, we have established with a scientific committee a formula containing a probiotic strain recognized for acting on the skin microbiota and thus allowing it to regain its balance.
Dietary supplements are a reliable way to provide high quantities of quality probiotics to preserve your microbiota. In winter, the Immunity Program is the ideal treatment to boost your immune system and fight against the drop in temperatures.
It is also beneficial to incorporate antioxidants into your dietary supplement routine. Antioxidants, such as vitamin C and vitamin E, help protect the skin against damage from free radicals, thereby contributing to healthier and more radiant skin. Additionally, essential fatty acids, like the omega-3s found in fish oil or flaxseed oil, promote hydrated skin and reduce skin inflammation.
Another supplement to consider is collagen. Collagen is an essential protein for the structure and elasticity of the skin. Collagen supplementation can help reduce signs of aging by improving skin elasticity and promoting cell regeneration.
We also offer dietary supplements for the skin that combine several of these elements for a holistic approach. By combining these supplements with a balanced diet and an appropriate skincare routine, it is possible to maintain the balance of the skin microbiota and promote healthy, radiant skin.
How does the intestine influence the health of our dermis?
The gut microbiota influences the health of our dermis by producing beneficial metabolites that reduce systemic inflammation. A healthy gut promotes radiant skin and reduces the risk of skin conditions such as acne and eczema. Studies show that gut bacteria can modulate immune responses, which directly reflects on the quality and resilience of the skin against external aggressions.
How can dietary supplements help balance the skin microbiota?
Dietary supplements can help balance the skin microbiota by providing high-quality probiotics that promote the growth of good bacteria. They help maintain the integrity of the skin barrier and prevent infections. In addition to probiotics, some supplements contain prebiotics, which serve as food for the good bacteria and thus strengthen the skin ecosystem.
How to take care of the skin microbiota?
To take care of the skin microbiota, it is essential to use suitable skincare products, maintain good hygiene without excess, and consume a diet rich in prebiotics and probiotics. Avoiding harsh cosmetics that can damage the protective lipid film is also crucial. Additionally, reducing stress and adopting a healthy lifestyle can have beneficial effects on the skin flora.
How to restore microbiota and skin?
To restore the microbiota and skin, it is recommended to use specific dietary supplements, consume foods rich in prebiotics and probiotics, and adopt a gentle and skin-friendly care routine. It is also advised to avoid excessive exposure to environmental stress factors, such as pollution and UV rays, which can disrupt the skin's balance.
Which probiotic for a beautiful appearance?
Probiotics such as lactobacilli and bifidobacteria are particularly beneficial for a beautiful appearance. They help maintain the balance of the skin microbiota and prevent skin conditions. In addition to these strains, some supplements contain vitamins and minerals that support skin health, such as vitamin C and zinc.
What are the consequences of an imbalance in the microbiota on the beauty of the dermis?
An imbalance of the skin microbiota can lead to conditions such as acne, eczema, and psoriasis. It can also cause dry, irritated skin that is prone to infections, thereby affecting the beauty and health of the dermis. Signs of an imbalance may also include redness, itching, and hypersensitivity to skincare products.
What are the best foods to nourish a healthy skin microbiome?
The best foods to nourish a healthy skin microbiota are those rich in prebiotics and probiotics, such as garlic, onion, fruits and vegetables, as well as fermented foods like yogurt and kefir. Spices and aromatic herbs also have beneficial anti-inflammatory properties. Foods rich in omega-3 fatty acids, such as fatty fish and nuts, can also contribute to a balanced skin microbiota.
