LightsheerDuet半导体激光脱毛的临床疗效

Clinical efficacy of hair removal by using Lightsheer Duet diode laser

目的探讨LightsheerDuet半导体激光对不同部位脱毛的疗效及安全性，比较大激光孔高速手具及标准手具两种模式脱腋毛效果的差异性。方法使用LightsheerDuet半导体激光脱毛仪对200例要求脱毛治疗者的不同部位进行脱毛治疗，4～8周治疗1次，4次为1个疗程。观察治疗后的疗效及不良反应。选取其中30例腋下脱毛者，采取自身左右对照方式治疗，即左侧腋下采用高速手具、右侧腋采用标准手具进行治疗，观察疗效有无差异。结果200例脱毛治疗者经过4次治疗后毛发较治疗前明显减少，总有效率达95．45％，且随治疗次数的增加，总有效率相应增高。3例出现色素沉着，均在治疗后1～3个月内消退。30例腋下脱毛者中，两种治疗手具3次脱腋毛治疗后总有效率均为100％，两者差异无统计学意义，高速手具脱毛疼痛更轻微。结论LightsheerDuet半导体激光脱毛是安全、高效的脱毛方法，其中的高速手具操作更快速、舒适。

Objective To evaluate the efficiency and safety of hair removal in different areas with Lightsheer Duet diode laser and to compare clinical effect and safety in axillae hair removal be- tween the two models, high-speed and standard model. Methods Lightsheer Duet diode laser was used to remove hairs from different areas in 200 cases, for 4-8 weeks treatment 1 time, 4 times for 1 course. The curative effect and adverse reaction were observed after the treatment. Thirty axillae hair removal subjects were chosen randamly and received treatments using the different models, high-speed hand piece on one side and the standard hand piece on the other side. Hair removal efficiency and the immediate pain were compared and evulated on each subject. Results The hair was significantly re- duced after 4 times treatments in 200 cases. The total effective rate was 95. 54% and positively related with the treatment times. Pigmentation was found in 3 cases, but it disappeared after 1-3 months. The total effective rate was 100 % after the 3 times treatments in axillae hair removal sub- jects both using the high-speed model or the standard model in 30 cases. There was no statistical difference between the two models except less pain in the high-speed model. Conclusions Lightsheer Duet diode laser is a safe and efficient method in hair removal. The high-speed model has more advan- tage on speed and causing pain.
