Skin resurfacing uses controlled injury to resurface the outer skin layer for a smoother, more youthful appearance and includes chemical peels, dermabrasion or laser surgery. Chemical peels include light, medium-depth and deep peels. The type of peel depends on the chemical used and how long it is left on the skin. Dermabrasion uses a high-speed rotary wheel to abrade or remove the surface layers of skin. Also, the pressure applied and the length of time it is applied to the skin determines the depth of the treatment. Laser resurfacing, AKA a laser peel, uses concentrated beams of light energy to eliminate damaged skin and cause it to flake off.
