Prebiotics and probiotics have become key ingredients in the field of cosmetics, particularly for their benefits on skin health.
Demain Beauty incorporates 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 protective shield. These bacteria produce antimicrobial substances that prevent pathogens from establishing themselves 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 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.
Demain products are enriched with prebiotics, probiotics and postbiotics 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 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 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
A prebiotic is a substance that feeds the good bacteria in our microbiome, whether in the gut or on the skin. Unlike probiotics , which are live microorganisms, prebiotics serve as "fuel" for these beneficial bacteria, promoting their growth and activity.
They are mainly made up of specific dietary fibers (such as inulin or fructo-oligosaccharides), which our body does not digest but which are fermented by the microbiota. This process generates beneficial compounds, including short-chain fatty acids, which contribute to the balance of intestinal and skin flora.
Demain Beauty treatments incorporate prebiotics to preserve the skin's natural balance and make it healthier day after day.
Probiotics: allies of healthy skin
A probiotic is a live microorganism, primarily bacteria or yeast, that provides health benefits when consumed in sufficient quantities. It works by strengthening the microbiome, the essential ecosystem of microorganisms found on our skin and in our gut.
In cosmetics, probiotics applied to the skin support the skin microbiome by stimulating good bacteria and limiting the growth of pathogens. This helps strengthen the skin barrier, soothe sensitive skin, and reduce imbalances such as redness or acne.
Proven benefits for the skin: the 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.
