Laser skin resurfacing.

There has always been interest in looking younger, but recently there seems to have been an explosion of public interest in facial rejuvenation. Physicians have been treating photodamaged skin for many years by removing the epidermis and a variable thickness of dermis with dermabrasion or chemical peels, with the expectation that reepithialization and collagen remodeling will result in a more youthful appearance. With the recent development of short-pulsed high-peak power and rapidly scanned carbon dioxide (CO2) lasers, the ability to remove photodamaged skin in a precise and reproducible manner while leaving behind a narrow zone of thermal damage has been achieved. This development has generated tremendous interest in laser skin resurfacing as a technique to reverse photoaging.
