Cosmelan® is a depigmentation treatment for the skin (face and hands) ageing caused by systematic sun exposure, facial blemishes due to excessive pigmentation and, in general, imperfections caused by melanin. Its treatment action mechanism is based on the inhibition of tyrosinase, a basic enzyme in the melanin formation process. Several of the substances present in the Cosmelan® formula act by blocking this enzyme, or even by inverting the metabolic process of the transformation chain. Roberto Vasquez O.
