BACKGROUND
Hirsutism and hypertrichosis are common problems for which a permanent solution has been elusive. Laser-assisted hair removal is a promising technique. However, the optimal wavelength, pulse duration, and fluence continue to require further investigation.
OBJECTIVE
To determine if the long-pulse Q-switched Nd:YAG laser is safe and effective in reducing facial and non-facial trunk hair.
METHODS
Fifteen patients were treated with a 30 msec pulsed Q-switched Nd:YAG laser at fluences between 125 and 150 J/cm2. The reduction of hair density was assessed at baseline and at 7, 30, and 90 days after treatment. Potential complications were also evaluated.
RESULTS
The average hair reduction was 36% at 7 days, 52% at 30 days, and 59% at 90 days. No significant complications or adverse events were reported.
CONCLUSION
The long-pulse Q-switched Nd:YAG laser provides a safe and effective means of hair removal.
背景
多毛症和毛发过多是常见问题，一直难以找到永久性解决方案。激光辅助脱毛是一种有前景的技术。然而，最佳波长、脉冲持续时间和能量密度仍需进一步研究。
目的
确定长脉冲调Q Nd:YAG激光在减少面部和非面部躯干毛发方面是否安全有效。
方法
15名患者接受了脉宽为30毫秒的调Q Nd:YAG激光治疗，能量密度在125至150 J/cm²之间。在基线以及治疗后7天、30天和90天评估毛发密度的降低情况。还评估了潜在并发症。
结果
7天时平均毛发减少率为36%，30天时为52%，90天时为59%。未报告明显并发症或不良事件。
结论
长脉冲调Q Nd:YAG激光提供了一种安全有效的脱毛方法。
