激光脱毛的临床应用

Clinical application of laser hair removal

体毛过多是一种常见的美学问题,传统脱毛方法的共同缺点是难以破坏毛母质和毛囊干细胞,故只能达到暂时性脱毛的效果。激光脱毛技术基于选择性光热动力学原理,可选择性地被毛囊内黑素颗粒吸收,产生光热效应,将毛球及毛囊干细胞彻底破坏,产生永久性脱毛,具有方便快捷,安全高效,效果永久性等特点。近年来激光脱毛仪器不断改良问世,受到了广大群众与皮肤科医师的深切关注。该文综述了激光脱毛技术的发展、作用原理、临床应用及相关影响因素。

Excessive hair is a common aesthetics problem. A common shortage of traditional methods for hair removal is that hair matrix and follicular stem cells are hardly destroyed by these methods, therefore the effect of hair removal is only temporary. Laser hair removal is based on the theory of selective photothermolysis. The energy of laser could be selectively absorbed by melanin in hair follicle. By which, follicular bulge and follicular stem cells are totally destroyed via photothermal effect. The laser hair removal is a convenient, safe, high effective method with permanent effect. In recent years, some new devices of laser hair removal have been introduced and aroused wide concern of costumers and dermatologists. In this paper, the development history, mechanisms, clinic applications and other related factors of laser hair removal were reviewed.
