Biologique Recherche Lotion P50
Nobody has copied this, and the ingredient list explains why. Five acids, niacinamide and sulfur in one water-based lotion, from a brand that will not sell it in a department store. Every product sold as a P50 alternative reproduces the acids and leaves out everything else, which is most of it.
Price and availability are set by Biologique Recherche.
Why we like the Lotion P50
- Fifty ingredients doing several jobs at once rather than one active and a base
- Biologique Recherche publishes the whole list, which plenty of brands at this price will not
- A hundred dollars for 150ml, which works out cheaper per use than the small bottle and lasts most people a season
- Texture
- Watery lotion applied on a damp cotton pad, not a rinse-off. The 150ml bottle.
- Key ingredients
- Gluconolactone · Lactic acid · Niacinamide · Malic acid · Salicylic acid · Sulfur
