Gently apply with the fingertips until complete absorption. Use Sérum Erythros during a course lasting at least 3 months.

About the Brand
Founded in Paris in the late 1970s by biologist Yvan Allouche and physiotherapist Josette Allouche, Biologique Recherche began as a laboratory for bespoke, high-performance formulas for elite skin professionals. Their medical-grade precision and artisanal formulation, paired with consummate savoir-faire, underpin their reputation for outstanding, clinically proven results.
Biologique Recherche treats skin according to its Skin Instant©, the skin’s precise, evolving state. Each formula is loaded with active ingredients in exceptional concentrations, then prescribed to address those real-time needs. This precision approach corrects imbalances, restores function, and delivers visible, lasting transformation.
Cold-processed actives are the core of Biologique Recherche. Formulated at 18–25°C, this method avoids the 70°C heat of standard processing that breaks down actives. Botanical, marine, and biotechnological extracts stay intact for higher absorption, stronger repair, and better tolerance. Antioxidants, peptides, and enzymes remain stable, ensuring consistent, visible results.
