dermabrasion

dermabrasion A surgical procedure that involves the controlled scraping away of the upper layers of the skin by using sandpaper or some other mechanical means. The purpose of dermabrasion is to smooth the skin and, in the process, remove small scars (as from acne), moles (nevi), tattoos, or fine wrinkles. Dermabrasion is performed by a dermatologist. Chemical skin peels are an alternative to dermabrasion.
