Ablative skin resurfacing lasers were developed in the early 1990s. These resurfacing devices utilized high fluence, pulsed carbon dioxide (CO 2 ) lasers. They produced dramatic clinical results in the treatment of photodamaged facial skin, rhytids, lentigines, and dermal elastosis. However, this laser treatment frequently had a prolonged recovery with associated pinkness and risk of potential complications. These issues made laser resurfacing a less attractive skin rejuvenation option. 1 This led to the development of other devices including fractional lasers. The first fractional lasers were nonablative. These were soon followed by ablative fractional lasers. These lasers provide clinically significant results with increased tolerability, lower risk of complications than ablative resurfacing, and a relatively minimal recovery. 2
BackgroundFractional photothermolysis has revolutionized laser skin resurfacing by providing significant improvement in clinical results with a relatively mild posttreatment recovery. There are also lower complication rates and associated morbidity.
