Photoaging is mainly characterized by rhytides,telangieetacia,dyschromia,hyperkeratosi,etc.Fractional photothermolysis has created a therapeutic option for these medically recalcitrant conditions.The technology is classified into two kinds,i.e.,nonablative fractional laser and ablative fractional laser,and the latter mainly includes fractional CO_2 laser and fractional erbium laser.This article describes the clinical application and side effects of,as well as histology changes after irradiation with the above lasers.
