Lotion P50
Benefits
Biologique Recherche Lotion P50 is a rebalancing, exfoliating toner that renews the skin’s surface to refine texture, clarify the complexion, and strengthen the skin barrier.
A synergistic blend of AHA, BHA, and PHA acids supports controlled cellular turnover to smooth roughness and minimise pores, while Niacinamide regulates sebum production and calms inflammation for a clearer, more even appearance.
Sulphur purifies and rebalances the skin’s microbiome, helping to prevent congestion, while Onion, Myrrh & Myrtle Extract kill acne forming bacteria.

About the Brand
For you if
Not For you if
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.
