Acne scarring is often treated with dermabrasion and results are evaluated using photographs. We have studied 25 patients before treatment and up to 1 year after dermabrasion for acne scars. Comparisons of results evaluated in different ways show that dermabrasion works best for superficial scars, results for more severe forms of scarring being less predictable.
