Microdermabrasion (often referred to as Microderm) is a family of cosmetic procedures  in which the stratum corneum (dead outermost surface of the skin) is partially or completely removed by light abrasion, thus eliminating sun-damaged skin. It can also be used to remove or lessen scars and dark spots on the skin.

The procedure is hardly painful and requires no anaesthetic. Microdermabrasion can be used medically for scar removal when the scar is raised above the surrounding skin, but is less effective with sunken scars. There is some evidence that microdermabrasion stimulates collagen formation. Microdermabrasion can also be used for treatment of acne, but must be repeated periodically to be effective.
