Biologique Recherche is a French skincare brand that offers a range of products, including the Lotion P50, which is a popular exfoliating toner. Here are some details about the brand, its products, and their ingredients:

• Brand Overview: Biologique Recherche is a complicated and confusing skincare line that doesnt cater to distinct skin types. Instead, it subscribes to the idea that our skin is an ever-changing thing with different needs at different times of the month, week, and even day. Biologique Recherche refers to this as a Skin Instant, and their products cater to the variety of Skin Instants they identify.

• Lotion P50: Biologique Recherches Lotion P50 is an exfoliating toner that comes in several formulations. The original formula, Lotion P50 1970, contains phenol, which is a strong exfoliant. The newer formulations, such as Lotion P50 and Lotion P50 PIGM 400, do not contain phenol but still offer exfoliating benefits. The ingredients in Lotion P50 vary depending on the formulation, but some common ingredients include water, lactic acid, gluconolactone, and niacinamide.

• Positive: Biologique Recherche products are cruelty-free.

• Negative: There is no information available on negative aspects of Biologique Recherche products.

• Ingredients or Materials: The ingredients in Biologique Recherche products vary depending on the formulation. Some common ingredients include water, lactic acid, gluconolactone, niacinamide, and various plant extracts. The brand does not use distinct skin types to categorize its products, but instead, it identifies different Skin Instants and offers products that cater to each one.
