激光脱毛380例临床分析

目的 探讨激光脱毛的效果，并总结380例激光脱毛经验。方法 采用800nm波长、脉宽30ms的半导体激光脱毛机，根据不同部位，选择不同能量及不同时间间隔。发际选择最低能量19J／cm^2，间隔3～4周后，再做下一次治疗，每次需增加1～2J／cm^2，经过3～5次治疗，最高能量达到25J／cm^2。小腿选择最低能量36J／cm^2，间隔7周左右再做下一次治疗，每次需增加2～3J／cm^2。每次治疗后，均无需特殊处理。结果 观察1／2～1年95％效果良好。20例治疗后出现过几个或多个斑点状色素沉着，有6例2个月后消失，即在第2次治疗时消失，有8例3个月消失，即第3次治疗时消失，还有4例是4个月后消失，仅有2例肤色较深者(含黑素较多的人)，在治疗后观察1年时，仍有少量色素沉着。结论 激光治疗后初期毛发的再生延迟，新生毛发质地由粗变细，颜色由深变浅，需经多次治疗。根据毛发部位的不同，选定不同的能量，才能最终达到永久性脱毛的目的。

Laser epilation : a clinical analysis of 308 cases

Objective To summarize 380 cases of the laser hair removal experience. Methods Using 800nm's wavelength of wide 30ms diode laser hair removal machine, different energy of selection and the time interval were different according to the different positions such as: the lowest energy 19J/cm 2 of hairline was selected and treated once at the interval of 3 - 4W with increasing 1-2J/cm 2 every time, as a result of 3 -5 times had been taken for cure. For legs, the lowest dose was 36 J/cm 2 . The highest energy achieved at 25J / cm 2 with interval 7 weeks, and it needed to increase 2-3J/cm 2 every times, and a total of 3 to 5 times were used for the treatment. After treatment each time, no special care was needed. Results The pati ents were followed up for more than half a year to 1 year. Cure rate was 95 %. Thereinto 20 persons appeared several spots of pigmentations after treatment, and those disappeared within 2 to 4 months. Only 2 persons with dark color of the skin still had slight pigmentation after 1 year. Conclusion Hairs treated many times by laser show regeneration delay and become thin in quality in the newborn hairs with lighting in color. The different energy is chosen for the treatment according to the different hair position that finally achieves permanent hair removal.
