Chronologic aging contributes to deteriorating skin texture and tone. This process is exacerbated by years of ultraviolet light exposure leading to photodamage in the form of lentigines, rhytides, texture irregularity, and telangiectasia. Traditional resurfacing was first performed with a 10,600 nm carbon dioxide (CO2) laser and later evolved with the 2940 nm erbium-doped yttrium aluminum garnet (Er:YAG) laser either as a short pulse after CO2 laser or alone as a long-pulsed Er:YAG laser.
