LightSheer半导体激光脱毛的疗效评价

目的:评价LightSheer半导体激光脱毛的治疗效果。方法:运用LightSheer半导体激光脱毛系统,对97名患者共113个部位进行脱毛治疗,波长800nm,能量密度24-40J/cm2,脉冲宽度30ms,分别对治疗一次、二次及三次后的有效性进行分级评价。结果:97名患者共113个部位一次治疗后均出现毛发再生减少、再生延迟,再生毛发细小、浅淡。随着治疗次数的增加有效性分级提高。二次治疗后,60%以上可达到3级(毛发减少40-59%);三次治疗后,80%以上可达到3级。腋窝和唇毛部位约50%可达到4级(毛发减少60-79%)。结论:LightSheer半导体激光脱毛系统对亚洲人是安全和有效的,80%的患者经三次治疗后毛发可减少近60%,但要达到更好的疗效需更多次治疗。

Evaluation of the Efficiency in Hair Removal with LightSheer Diode Laser

Objective:To evaluate the efficiency of hair removal with LightSheer diode laser.Methods:97 patients totally 113 sites were involved.After irradiated 1 time,2 times and 3 times with LightSheer diode laser(wavelength:800nm,energy fluency:24-40J/cm2,pulse width:30ms),the effective rate was evaluated from Grade 1 to Grade 5.Results: After received 1 time treatment,the effective rate of all sites reached to Grade 1(0-19% reduction).After 2 times,over 60% reached to Grade 3(40-59% reduction).After 3 times,over 80% reached to Grade 3,about 50% of armpit and oral reached to Grade 4(60-79% reduction).Conclusions: Hair removal with LightSheer diode laser is safe and effective in Asian people.Hair reduced to almost 60% after irradiated for 3 times in about 80% patients.Better effects require more times of laser irradiation.
