Abstract

BACKGROUND: Lentigines solares (LS) on the dorsum of hands are often esthetically disturbing. Q-switched ruby laser treatment is highly effective in the treatment of these lesions. Ablative fractional photothermolysis may be a suitable alternative. We compared the Q-switched ruby laser with ablative CO2 fractional photothermolysis for the treatment of solar lentigines. OBJECTIVE: To evaluate the efficacy and side-effects of 694nm Q-switched ruby laser (Sinon) with the ablative 10,600nm CO2 fractional laser (Quantel Excel O2) in an int
