Dermabrasion is a treatment to improve the look of the skin. It uses a wire brush or a diamond wheel with rough edges to remove the upper layers of the skin. The brush or burr spins quickly, taking off and leveling (abrading or planing) the top layers of the skin.
The face is the most common site for this treatment. But other areas of the skin can be treated this way too. Dermabrasion is used most often to improve the look of acne scars and fine lines around the mouth.
