The skin is composed of several layers, the corneum layer is the outermost and superficial layer that is exposed to the environment. This layer is made up of dead cells, proteins and other components that make it strong to resist external aggression. Every day these dead cells are eliminated naturally, however, over the years, cell renewal decreases drastically and the process is slower and slower. As we age these cells accumulate on the surface of the skin. Exfoliants or scrubs help the skin to eliminate the cells accumulated in the epidermis, in addition, it improves the appearance of the skin, helps reduce wrinkles, improve scars and reduce blemishes.
