Abstract: Objective To examine and assess the clinical effect of Er ∶ YAG 2940 nm fractional laser resurfacing for skin wrinkles.Methods A total of 16 patients with Fitzpatrick skin type Ⅳ and facial wrinkles,were treated with Er ∶ YAG 2940 nm fractional laser resurfacing and follow-up were given every week after treatment,four weeks in all.Response to treatment was evaluated by observers and patients themselves.Photos were analyzed by the photoshop 12.0 software.Results During the four-week follow-up,the skin of patients was more and more better than pretreatment,and a large part of wrinkles was disappeared.The assessment of observers for wrinkle amelioration rose from (6.50--2.33) ％ to (34.80±5.24) ％ and the scores of content of patients was up to 4.00±0.27(generally satisfied),whereas no one satisfied at beginning.Analyzed by photoshop 12.0 software,the data of average and middle values were on the trend of increasing in all these four weeks while SD was basically on the trend of decreasing.Conclusions Fractional ablative photothemolysis using Er ∶ YAG 2940 nm laser is a promising option for skin wrinkles.
