强脉冲光祛除腋毛的临床疗效观察

Evaluation of effect of intense pulsed light on axillary hair removal

目的评价强脉冲光祛除腋毛的临床疗效。方法采用飞顿一号复合彩光仪对25例女性患者的双侧腋部进行脱毛治疗。治疗波长650～950 nm,能量密度13～17 J/cm2,脉冲宽度30～50 m s,疗程为2～5次,治疗间隔为8～9周,末次治疗结束后6个月评价患者的脱毛率。结果2次治疗后的脱毛率为（21.83±5.52）%,3次治疗后的脱毛率为（56.47±15.29）%,4次治疗后的脱毛率为（73.90±7.73）%,5次治疗后的脱毛率为（89.77±3.62）%,不同治疗次数间脱毛率的差异有显著性（P〈0.01）。所有患者治疗局部皮肤即刻出现潮红伴不同程度的灼热和疼痛,可自行消退,无1例出现水疱、瘢痕、色素沉着和色素减退。结论强脉冲光祛除腋毛安全有效,并且治疗效果与治疗次数相关。

Objective To evaluate the efficacy of intense pulsed light（IPL） on axillary hair removal.Methods Axillary hair removal was performed on twenty-five female patients by using IPL for two to five treatments at 8 to 9 weeks interval.The energy density was delivered in the range of 13~17 J/cm2 by multiple pulse illumination with duration of 30~50 ms and wavelength of 650~950 nm.The assessment for percentage of hair reduction was conducted 6 months after the last treatment.Results The percentage of hair reduction after two treatments was（21.83±5.52）%,after three treatments was（56.47±15.29）%,after four treatments was（73.90±7.73）% while after five treatments was（89.77±3.62）%.The differences of treatment courses in hair removal efficiency were significant（P〈0.01）.All patients suffered from transient pain and erythema immediately after treatment.No adverse effects such as blister,scarring and pigmentation or hypopigmentation were observed.Conclusion Intense pulsed light is safe and effective on axillary hair removal,its effectiveness correlating with the number of treatment courses.
