BACKGROUND: Although ablative fractional laser for the facial photodamaged skin was effective and safe, there have been only limited reports regarding the efficacy and safety of fractional Er:YAG laser treatments for photodamaged facial skin in Asians. OBJECTIVE: Our objective was to assess the efficacy and safety of the Er:YAG laser (2940 nm) using the ''ablative'' fractional resurfacing mode to treat photodamaged facial skin. METHODS: A total of 29 Korean patients were treated for photodamaged facial skin using a fractional Er:YAG laser. The number of treatments was mean 2.3 sessions at two-week intervals. Independent investigators assessed the efficacy using standardized photographs. The patients' satisfaction rate was also evaluated. RESULTS: For dyspigmentation, 62.5% of the treated patients showed improvement greater than 26%. Regarding wrinkles, 50% of the treated patients showed improvement greater than 26%. All patients showed various degrees of improvement in skin laxity. Assessing the overall features, 62.5% of the study subjects showed improvement greater than 26%, and most of them (91.7%) reported that their subjective satisfaction rate was above 'slight satisfaction'. Downtime accounted for approximately one week in most patients. CONCLUSIONS: A fractional Er:YAG laser can deliver an effective and minimally invasive treatment for photodamaged facial skin in Asians.
