Probiotics
The benefits of probiotics for balanced and healthy skin
The skin microbiota: an essential ecosystem
Our skin is naturally home to millions of beneficial microorganisms that form a protective shield. These bacteria produce antimicrobial substances that prevent pathogens from establishing themselves on our epidermis.
The skin microbiota actively contributes to strengthening our immune system. Like a microscopic army, it educates our natural defenses and helps maintain an optimal pH for healthy skin.
Skin bacteria also perform an essential metabolic function. They convert sebum and other secretions into beneficial nutrients for the skin, promoting its natural hydration and regeneration.
Nearly a billion different microorganisms live on every square centimeter of skin, creating a unique ecosystem as personal as our fingerprints.
The importance of a balanced microbiota
A harmonious skin microbiota is the key to radiant skin. This perfect symbiosis between different bacterial populations allows for better sebum regulation and enhanced protection against external aggressions.
Research shows that an imbalance in the microbiota can trigger various reactions such as redness, sensitivity, or blemishes. Conversely, a balanced skin flora strengthens the skin's natural barrier and promotes its regeneration.
Dermatologists observe that skin with a stable microbiota is more resilient to environmental factors such as pollution and UV rays. This stability results in a more even complexion and improved skin texture.
Factors that disrupt skin balance
Air pollution and UV rays are the primary aggressors of our bacterial flora. These environmental elements alter the diversity of beneficial microorganisms and weaken the skin's natural defenses.
Excessive use of harsh cleansers or antibacterial solutions alters the skin's natural pH. This chemical imbalance disrupts the composition of protective microbial populations.
Stress, an unbalanced diet, and lack of sleep also affect the stability of this living barrier. A concrete example: during a period of prolonged anxiety, excessive cortisol production disrupts the renewal of beneficial bacteria and promotes the appearance of skin inflammation.
Probiotics: allies of healthy skin
Mechanisms of action on the epidermis
Probiotics exert a regulatory effect on the skin through several complex biological processes. These microorganisms stimulate the production of natural antimicrobial peptides that strengthen the skin's defenses.
At the cellular level, they promote the synthesis of ceramides and essential fatty acids, strengthening the barrier function of the epidermis. This unique metabolic activity allows for better water retention in skin tissues.
The bioactive compounds released by probiotics also help modulate the local inflammatory response. For example, certain strains of Lactobacillus reduce the production of pro-inflammatory cytokines responsible for redness and irritation. This regulation helps maintain an optimal pH for soothed and balanced skin.
Types of strains used in cosmetics
Lactobacillus represents the most widespread family of strains in modern cosmetic formulations. Lactobacillus plantarum strengthens the skin barrier while Lactobacillus fermentum regulates sebum production.
Another major category includes Bifidobacterium, including Bifidobacterium longum and Bifidobacterium breve. These strains excel at preventing skin aging and soothing sensitive skin.
