Dermabrasion and Microdermabrasion can be utilized to alone or in combination to improve acne scarring. Mechanical skin resurfacing, which includes dermabrasion and microdermabrasion, involves using a handheld abrading instrument to remove layers of epidermis. Dermabrasion, a more invasive and technically difficult procedure, involves the removal of skin down to the level of the papillary dermis. Microdermabrasion, a less aggressive technique, involves abrasion of the superficial epidermis only. Microdermabrasion is a commonly performed superficial skin resurfacing treatment. Microdermabrasion devices are commonly found both in physicians' offices and non-medical aesthetic spas and microdermabrasion remains one of the frequently performed cosmetic procedures in the United States. Microdermabrasion is intended to remove superficial layers of the epidermis. Biochemical and histological impact of microdermabrasion remains controversial. Microdermabrasion is most commonly used to treat the following conditions: dry or rough skin, fine lines and wrinkles, solar damage, hyperpigmentation, and acne scarring.
