Fractionated CO2 laser resurfacing: our experience with more than 2000 treatments

Fractionated carbon dioxide (CO(2)) laser resurfacing combines the concept of fractional photothermolysis with an ablative 10,600-nm wavelength. This technology allows for the effective treatment of rhytides, photodamage, and scars, with shorter recovery periods and a significantly reduced side effect profile as compared to traditional CO(2) laser resurfacing. In this article, the authors review the concept of fractional photothermolysis, the expanding array of indications for use of fractionated CO(2) lasers, and their preferred treatment technique.
