强脉冲光脱毛远期疗效的初步观察

I.ong-term efficacy of intense pulsed light on epilation

目的探讨强脉冲光（intense pulsed light，IPI。）脱毛的远期临床疗效及安全性。方法应用IPI。对159例进行脱毛治疗，获远期随访者116例，平均随访时间为38个月。观察内容包括治疗区域毛发密度和生长速度，治疗后无毛发生长时间，色素沉着及水疱等不良反应发生情况等。以脱毛者对脱毛效果的主观满意程度评价治疗效果。结果经过IPI。治疗后再生的毛发显著稀疏细小，生长速度减慢。治疗后即刻脱毛部位有不同程度的红斑和灼痛感，毛囊周围出现荨麻疹样水肿，红斑、水肿一般在数小时内自然消退。极少部分脱毛者脱毛部位出现水疱、结痂及色素沉着，一般数天至数周消失。脱毛者对脱毛疗效总体满意度为76．7％，且疗效与肤色无关。结论IPI．是一种安全有效的脱毛方法。

Objective To evaluate the long-term effects and safety of an intense pulsed light （IPI.） in the treatment of epilation. Methods 159 patients received treatment with a non-coherent IPL because of unwanted facial and body hair. 116 cases were followed up by means of phone call or let ters. The average follow-up time was 38 months. Results Overall, 36 （31.0%） patients were very satisfied, 53 （45.7% ） were satisfied and 27 （23.3 %） remained unsatisfied with the outcome of light assisted hair removal. The non-coherent intense pulsed light satisfactorily removed unwanted dark hair. Hair free periods from weeks to years could be observed. Besides, the satisfaction was not relat ed with the colour of the skin. Conclusions Hair removal by a non-coherent intense pulsed light is an effective and safe method for long-term epilation of unwanted hair.
