What is Microdermabrasion? It is a skin-freshening technique that helps repair facial skin that has been affected from the sun and effects of aging.
It is a general term for the application of tiny rough grains to buff away the surface layer of skin. Many different products and treatments use this method, including medical procedures, salon treatments and creams and scrubs that you apply yourself at home. It's usually done to the face, chest, neck, arms or hands.
Your skin is made up of two main layers, the epidermis and the dermis. The epidermis is the layer closest to the outside world. It's a set of dead skin cells on top of another layer of cells that are in the process of maturing. The topmost layer is called the stratum corneum. The stratum corneum mostly acts as a barrier between the outside world and the lower skin layers. It keeps all but the smallest molecules from getting through. When you put lotions or creams on your skin, some of the moisture passes through the stratum corneum, but not all of it. This layer is home to many minor skin imperfections like fine wrinkle linesand blemishes.
All of the action in microdermabrasion takes place at the level of the stratum corneum.
