Biologique Recherche Sérum Vivant

Biologique Recherche Sérum Vivant

Biologique Recherche Sérum Vivant is a multi-corrective face serum developed specifically for adult skin prone to persistent blemishes. Born from the cult legacy of Masque Vivant, this daily formula approaches imperfections as a sign of skin imbalance, not something to be aggressively stripped away.

Its complementary prebiotic-postbiotic technology combines Yeast Extract, Inulin and Polylysine to help keep the skin's microbiome balanced while visibly reducing persistent blemishes, the look of associated redness, excess shine and uneven-looking texture.

The skin progressively appears clearer, calmer and more balanced while its protective barrier and comfort are preserved. The serum is suitable for sensitive skin and is made using a cold-process method to help preserve the quality of its active ingredients.

Why we love it

Adult blemish-prone skin can be oily, red, dehydrated and sensitive all at once, and drying out every imperfection often leaves it more uncomfortable. Sérum Vivant takes a broader approach: it helps control the look of excess oil without stripping it away. We love it for clients whose skin no longer tolerates aggressive, overly drying routines. A clearer-looking complexion should not come at the expense of the skin barrier.
