Lait S.R.Biologique Recherche Lait S. R. is a purifying skincare product that removes impurities and excess sebum without damaging the skin's balance. Its light texture preserves the hydrolipidic film, unclogs pores, and reduces shine. Ideal for seborrheic skin, it addresses hyperseborrhea, characterized by excessive sebum production, which can lead to oily skin and enlarged pores, especially in the T zone.
