Microdermabrasion is a general term for the application of tiny rough grains to buff away the surface layer of skin. Before touching on how it works, we’ll first review how skin works.
Our skin is made up of two main layers, the epidermis and the dermis. The epidermis is layer closest to the outside world and is a set of dead skin cells on top of another layer of cells that are in the process of maturing. The topmost layer of the skin is called the stratum corneum. This layer acts as a protective barrier between the outside world and the lower skin layers. It keeps all but the smallest molecules from getting through.
