BACKGROUND

Unwanted hair is a widespread cosmetic problem. Several lasers and intense pulsed light (IPL) have been utilized for this purpose. A new IPL device (Lumenis One) with OPT is one of the newer modalities to be studied in Chinese patients.

OBJECTIVE

This study evaluates the short-term efficacy and side effects of the new IPL device for epilation in Chinese patients.

METHODS

Eighteen Chinese women with Fitzpatrick skin types III-V and black hair, were treated four times at 4 to 6-week intervals using IPL (Lumenis One) on the axillae (n=13) and the upper lip (n=5). The energy density for treatment ranged from 14 to 22 J/cm(2). Parameters utilized were 695-/755-nm filters, triple pulse for patients on the axillae, and 640-/695-nm filters, double pulse for patients on the upper lip (3.5- to 7-ms pulse, 30- to 90-ms pulse delay, 15x35 mm spot size). Hair reduction was assessed at baseline, immediately before each treatment session, and at 4 weeks after the fourth treatment. Patient's satisfaction on a 5-point scale was also evaluated.

RESULTS

The average hair reduction for all sites was 49.9% after one session, 58.6% after two sessions, 79.3% after three sessions, and 83.8% after four sessions (p=0.001). The hair reduction of 44.1%, 52.1%, 81.1%, and 86.0% were achieved after each treatment for axillae, with 65.1%, 75.7%, 74.6%, and 78.0% for upper lip. Patients got more satisfaction after four sessions (score 3.1) than that after two sessions (2.0) (p=0.001). In both the assessments, upper lip appeared to show a better response than axillae after two IPL treatments, which reversed after four treatments. No significant complications or adverse events were reported.

CONCLUSION

The new IPL device provides a safe and effective means of hair removal for Chinese patients. Treatment efficacy varies with the anatomic location and number of treatments. However, further study is necessary to determine the long-term clinical efficacy in Chinese patients.

背景

多毛是一个普遍存在的美容问题。多种激光和强脉冲光（IPL）已被用于此目的。一种新型的带有优化脉冲技术（OPT）的IPL设备（Lumenis One）是在中国患者中进行研究的较新方式之一。

目的

本研究评估新型IPL设备对中国患者进行脱毛的短期疗效和副作用。

方法

18名 Fitzpatrick皮肤分型为III - V型且为黑发的中国女性，使用IPL（Lumenis One）对腋窝（n = 13）和上唇（n = 5）进行治疗，每隔4至6周治疗4次。治疗的能量密度范围为14至22 J/cm²。使用的参数为695 - /755 - nm滤光片，腋窝患者使用三脉冲，上唇患者使用640 - /695 - nm滤光片，双脉冲（3.5至7毫秒脉冲，30至90毫秒脉冲延迟，15×35毫米光斑大小）。在基线、每次治疗前即刻以及第四次治疗后4周评估毛发减少情况。还评估了患者5分制的满意度。

结果

所有部位的平均毛发减少率在一次治疗后为49.9%，两次治疗后为58.6%，三次治疗后为79.3%，四次治疗后为83.8%（p = 0.001）。腋窝每次治疗后的毛发减少率分别为44.1%、52.1%、81.1%和86.0%，上唇分别为65.1%、75.7%、74.6%和78.0%。患者在四次治疗后（评分3.1）比两次治疗后（2.0）更满意（p = 0.001）。在这两项评估中，两次IPL治疗后上唇的反应似乎比腋窝更好，但四次治疗后情况相反。未报告明显的并发症或不良事件。
