Balancing exfoliators are the unique fruit of 30 years of reflection and experience. P50T balancing exfoliators speed up the epidermis' natural exfoliating process and the reconstruction of the epidermal shield. The fortified epidermis can then fulfill its protective functions completely, enhancing skin's self-regeneration potential. Lotion P50T, our most famous and coveted product, is the keystone to Biologique Recherche skin care treatment. All Biologique Recherche skin care treatments, whether administered at home or in a beauty institute, start with the P50T ritual"". It is applied in the morning and in the evening. It gently exfoliates the skin, regulates excessive sebum secretion, moisturizes and helps maintain the epidermis' acid pH. It prevents and treats in-growing hairs, and is therefore ideal for pre and post shaving skin care."
