深肤色人种的激光脱毛

Laser assisted hair removal on dark-skinned patients

当今激光技术飞速发展，提高了激光脱毛的临床疗效，并使我们增加了对毛发生理及激光-组织相互作用的认识。配有冷却装置的长脉宽、长波长激光的应用，使得激光脱毛能够安全有效地应用于深肤色人种（皮肤Ⅳ～Ⅵ型）。目前主要用于深肤色人种脱毛的光源有长脉宽翠绿宝石（755nm）、长脉宽半导体（800nm）、长脉宽Nd：YAG（1064nm）激光和强脉冲光（590．1200nm）。但其中长脉宽Nd：YAG激光在深肤色人种脱毛中更为安全。

With the development of laser technology, the effect of laser-assisted hair removal has been greatly improved, and now more about physiology of hair and interaction between laser and tissue are understood. Using long-pulsed and long-wavelength laser technology with cooling system, laser assisted hair removal on dark-skinned patients become safer and more effective today. The most frequently used light sources for hair removal on dark-skinned patients include the long-pulsed alexandrite （755 nm）, long-pulsed diode （800 nm）, long-pulsed Nd：YAG （1 064 run）, and intense pulsed light （590 - 1200 nm）. The long-pulsed Nd：YAG laser represents the safest device for hair removal on dark-skinned patients because of its long wavelength, although the alexandrite laser, diode laser, and intense pulse light may be used.
