Each of the three skin resurfacing procedures -- chemical peels, dermabrasion and laser resurfacing -- is essentially trying to achieve the same result using different methods. The goal is to rid yourself of the top layers of your skin to expose newer and younger looking skin underneath. For peels, you'll have chemicals applied to your skin that will essentially blister away the outermost layer and then heal over a period of days or weeks, depending on the chemicals used. They range from light to heavy to treat different levels of wrinkling.
Dermabrasion injures your skin much in the same way a skinned knee might, leaving a scab that will eventually fall away to reveal the new skin beneath it. This procedure requires anesthetic and a small spinning wheel is applied to the skin to basically sand off the outermost layer. Recovery time is a bit longer than with a peel, but the results can be more effective.
Laser resurfacing is similar to the dermabrasion, but a laser is used instead of an abrasive spinning wheel. Laser techniques improve the precision of the procedure, with doctors more able to accurately pinpoint delicate areas around the eyes and mouth. The laser technique is the newest form of skin resurfacing procedure and gets high marks for consistently even results.
