Lasers in skin resurfacing

Abstract

The development of short-pulse high-peak power and rapidly scanned focused beam carbon dioxide lasers and normal mode erbium:yttrium aluminum garnet lasers, which can remove photodamaged skin layer by layer in a precisely controlled manner while leaving behind a very narrow zone of thermal damage, has revolutionized skin rejuvenation and enhanced our ability to treat scars. This review highlights laser-tissue interactions; the laser used for resurfacing; preoperative, operative, and postoperative issues and how to choose a candidate for the procedure; uses of resurfacing; adverse effects and complications of the procedure; and new developments in the field.
