Microdermabrasion is a general term that refers to the process of applying very tiny rough grains of crystals, to peel off the outermost surface of the skin. It's aim is to remove the topmost layer of the skin called the stratum corneum to create a rejuvenating effect and treat common skin problems such as acne scarring and mild discoloration, sun damage and wrinkles. It is a painless non-surgical procedure. The procedure can be administered to patients from the age of 12 and can be done as frequently as two weeks depending on the skin's sensitivity and tolerance. Since the human outer skin typically regenerates itself every 30 days, microdermabrasion has to be done on a regular basis or in weekly sessions in order to record significant improvement on the skin's cosmetic health.
