Prebiotics and probiotics have become key ingredients in the field of cosmetics, particularly for their benefits on skin health.
The French brand Demain Beauty integrates these active ingredients into its products to strengthen the skin and intestinal microbiota, thus promoting holistic beauty.
Our skin is naturally home to millions of beneficial microorganisms that form a real protective shield. These bacteria produce antimicrobial substances that prevent pathogens from settling on our epidermis.
The skin microbiota actively participates in 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 transform sebum and other secretions into nutrients that benefit the skin, promoting its natural hydration and regeneration.
On every square centimeter of skin live nearly a billion different microorganisms, creating a unique ecosystem as personal as our fingerprints.
Demain products are all enriched with prebiotics and probiotics because we are committed to taking care of your skin microbiota.
The benefits of prebiotics and probiotics for balanced and healthy skin
A harmonious skin microbiota is the key to radiant skin. This perfect symbiosis between the different bacterial populations allows for better regulation of sebum 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 has better resistance to environmental factors such as pollution or UV rays. This stability translates into a more uniform 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 natural defenses of the epidermis.
Overuse of harsh cleansers or antibacterial solutions alters the skin's natural pH. This chemical imbalance disrupts the composition of protective microbial populations.
Stress, unbalanced diet and lack of sleep also affect the stability of this living barrier.
A concrete example: during a period of prolonged anxiety, excessive production of cortisol disrupts the renewal of beneficial bacteria and promotes the appearance of skin inflammation.
Definition and role of prebiotics and probiotics in cosmetics
Natural sources of prebiotics
Natural plant fibers are the main source of prebiotics in cosmetics.
Inulin, extracted from chicory root, is distinguished by its ability to nourish good skin bacteria.
Beta-glucans, derived from oats or yeast, represent another major family of prebiotics . These active ingredients strengthen the skin's natural resistance to daily aggressions.
Polyphenols extracted from green tea or grapes also enrich cosmetic formulas with prebiotics. Their antioxidant power reinforces the beneficial action on the epidermis.
Probiotics: allies of healthy skin
Mechanisms of action on the epidermis
Probiotics exert a regulatory action 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, consolidating the barrier function of the epidermis. This unique metabolic activity allows 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.
Proven benefits for the skin: proven results of Demain beauty treatments
Clinical tests demonstrate the remarkable effectiveness of Demain beauty formulas. Users notice a visible reduction in redness after 14 days of use, with more comfortable and soothed skin.
The unique combination of prebiotics, probiotics and postbiotics in the care reveals impressive results: 89% of participants note a significant improvement in hydration after 28 days.
The skin barrier is naturally strengthened, while the complexion becomes more luminous.
Instrumental measurements confirm a 42% decrease in imperfections and a 37% increase in skin elasticity. The skin texture becomes smoother, softer, regaining all its natural radiance.
