Biologique Recherche


A mild though effective iteration of the cult-favourite Lotion P50, this melanin-regulating acid-toner is ideal for both compromised and sensitive skins and those experiencing sun-induced or hormonal pigment inconsistencies. Harnessing the resurfacing and refining properties of Poly, Alpha and Beta-Hydroxy-Acid Complexes, this liquid exfoliant encourages cellular turnover while managing melanocyte synthesis. Ideal in breaking down existing pigment and preventing future pigment from surfacing, this gentle formula lightens and brightens the complexion with Red Algae and a patented Fruit Complex rich in Flavonoids, while Yeasts, B Vitamins and Sulphur balance the pH and microbiome to improve barrier function. Magnesium Chloride and Magnesium Sulfate ensure that new cells are as strong and healthy as possible, enhanced by Natural Moisturising Factors that condition and replenish the epidermis. Within two epidermal cycles over a 50 day period, Lotion P50 PIGM 400 unifies the skin tone, while improving skin strength, density and hydration with nightly use.
