About Biologique Recherche

French Skincare Without Compromise

Founded in the late 1970s by biologist Yvan Allouche and physiotherapist Josette Allouche, Biologique Recherche pioneered a clinical, skin-first approach to skincare. Its potent formulas and treatment protocols are designed to treat the skin exactly as it presents, with routines tailored to each person's needs.

Discover icons like Lotion P50, Masque VIP O2 and La Grande Creme, and experience the methodology that made Biologique Recherche a cult favorite among skincare professionals.

The Science

A CLINICAL, SKIN-FIRST METHODOLOGY

Biologique Recherche formulas are built around potent active ingredients and a methodical approach: assess the skin as it is today, then treat exactly what it needs. Routines are personalized rather than one-size-fits-all, and products are layered in a precise order.

THE ROLE OF LOTION P50

Lotion P50, the brand's signature exfoliating lotion, is the foundation of most routines. It refines texture, helps balance the skin and prepares it so the serums, masks and creams that follow can work more effectively.
