The microbiota: the fourth layer of the skin

The microbiota, also known as microbial flora or microbiome, refers to the community of microorganisms that inhabit our body, particularly in the gastrointestinal tract, skin and other areas. They include bacteria, viruses, fungi and other microorganisms. The microbiota plays a crucial role in our overall health and well-being.

The skin microbiota is made up mainly of bacteria found in the outer layer of the skin, the epidermis, and in the hair follicles. Today we know that it is so important for skin health that we like to call it the fourth layer of the skin.

These beneficial microorganisms, in healthy skin, form a protective barrier that helps defend the skin against harmful pathogens and maintain its balance and integrity. Additionally, they interact with skin cells and the immune system, contributing to the skin's immune response.

As in the intestine, the balance of the skin microbiota is essential for our health. An imbalance in the microbiota can contribute to various skin problems, such as dryness, redness, itching, sensitivity, acne, and other pathologies.

Several factors can affect the composition of the skin microbiota, including genetics, personal hygiene, diet, exposure to the sun or environment, and the use of skin care products. Excessive use of astringents, antimicrobials or topical antibiotics can alter microbial diversity and negatively affect the balance of the microbiota. Natural soaps, for example, are very aggressive and can unbalance our skin's bacterial flora. We always recommend the use of syndet gels or cleansers. for both the body and the face.

Does it make sense to use cosmetics with probiotics? We like to know the latest and use the penultimate... More studies are needed on the microbiota. Probiotics are living organisms that would die in the presence of preservatives, so necessary to guarantee the safety of cosmetics. Extracts derived from probiotics are currently used and seem to be interesting. But what we do know for sure is that our lifestyle and our cosmetic routine can greatly influence the balance of the skin's microbiota.

Our tips promote a healthy balance of the skin microbiota:

  • Proper cleaning: Use mild, non-aggressive syndet products to clean the skin, avoiding excessive use of antimicrobial soaps that can eliminate beneficial microorganisms.

  • Moderate use of skin care products : avoid excessive use of astringent, antimicrobial or topical antibiotic cosmetic products.

  • Hydration: Keeping skin hydrated helps maintain the skin barrier and microbiota balance.

  • Balanced diet: A diet rich in fiber, fruits, and vegetables can promote an overall healthy microbiome, which in turn can have a positive impact on the skin microbiota.

  • Avoid stress: Chronic stress can negatively affect the skin microbiota. Practicing stress management techniques, such as meditation or exercise, can help maintain a healthy balance.

  • Use photoprotectors and other methods of sun protection , mainly in summer.

In summary, the skin microbiota plays a crucial role in the health and balance of the skin. Maintaining a balanced skin microbiota is essential for healthy skin. By following proper care practices and promoting a healthy balance, we can maintain a healthy skin microbiome and promote radiant skin.
