摘要目的 探讨半导体激光和长脉冲翠绿宝石激光对不同类型皮肤脱毛的效果与并发症.方法 将1103例(1760部位)按皮肤类型随机分为两组;一组使用半导体激光治疗,波长810 nm,脉宽400 ms,方形光斑12 mm×10 mm;另一组使用长脉冲翠绿宝石激光治疗,波长755 nm,脉宽20 ms,光斑直径12.5 mm,2次治疗间隔时间均为50～60 d.结果 两种治疗方法对不同类型的皮肤进行脱毛治疗,效果无明显差异,但对深肤色者,半导体激光治疗的并发症发生率低.结论 两种激光对不同类型皮肤脱毛效果相似,但半导体激光对深色皮肤的脱毛更安全.

abstractsObjective To explore the effect and complication of diode laser and long-pulsed alexandrite laser for hair removal in different skin type.Methods A total of 1061 patients (1741 sites) were divided into 2 groups by skin type:one group were treated with diode laser,with wave length of 810 nm,and pulse width of 400 ms,with 12 mm × 10 mm spot size; another group were treated with long-pulsed alexandrite laser,with wave length of 755 nm,of pulse width of 20 ms,with 12.5 mm spot size,50-60 days intermitted between each treatment.Results The effect of hair removal by two lasers in different skin type was without divergence,but to darker skin,complication was lower when treated by diode laser.Conclusions The effect of hair removal by two lasers in different skin type is similar,but diode laser on hair removal is much safer to dark skin.
