Biologique Recherche Sérum Vivant

Microbiome-Balancing Serum for Persistent Blemishes

Biologique Recherche Sérum Vivant is an advanced daily serum formulated for adult skin prone to persistent blemishes, excess sebum and visible redness.

Inspired by the iconic Masque Vivant, this multi-corrective formula takes a balanced approach to blemish-prone skin. Rather than stripping the skin, it combines prebiotic and postbiotic technologies to help support the skin microbiome while addressing visible imperfections, redness, excess oil and uneven texture.

With continued use, the complexion appears clearer, calmer and more balanced, while the skin’s natural barrier and comfort are maintained.

Key Ingredients & How It Works

Sérum Vivant combines three biotechnology-derived actives that work together to support a balanced skin microbiome and improve the appearance of blemish-prone skin.

• Yeast Extract is a signature postbiotic ingredient from the Vivant collection. Derived through the fermentation of Saccharomyces cerevisiae, it contains naturally occurring amino acids and bioactive metabolites that help support blemish-prone skin and address visible redness associated with imperfections.

• Inulin is a prebiotic polysaccharide that helps nourish beneficial microorganisms naturally found on the skin. By supporting microbial balance, it helps promote a healthy skin barrier and maintain comfort.

• Polylysine is a fermentation-derived biomimetic biopolymer made from lysine units. Its unique structure allows it to interact selectively with microorganisms associated with blemish-prone skin, including Cutibacterium acnes.

Together, these ingredients create a complementary prebiotic-postbiotic approach: prebiotics help nourish beneficial microorganisms, while postbiotics provide bioactive compounds that support the skin’s overall balance.

The result is a calmer, clearer and more balanced-looking complexion with improved comfort and a healthier-looking skin barrier.
