The main goal of this study was to compare the hair removal efficacy of three methods: intense pulsed light (IPL), a combination of IPL and radio frequency (RF) and diode laser (810 nm).
Forty participants were treated within three standardized squares on lateral sites on their legs. Each of these squares was treated twice with an interval of 4-6 weeks. The fourth square was left as a control. A blinded physician counted the hairs in each square before the first treatment and 8 months after the second treatment. Immediate and delayed side effects as well as pain scores were recorded.
The mean hair count reduction achieved by the diode laser, IPL and IPL+RF was 49.90%, 39.16% and 47.15%, respectively. This study did not show any serious side effects and the number of side effects was minimal. The mean pain scores for the first and second treatments by diode laser, IPL and IPL+RF were 4.65 and 4.58, 2.43 and 2.53, and 3.95 and 4.03, respectively. At the end of the study, a free hair removal treatment for both legs was chosen by patients in the proportion 20 diode laser, 10 IPL and eight IPL+RF.
The combination of RF and optical energies proved its safety and efficacy for hair removal, which is comparable with diode lasers and approximately 20% more efficient than 'pure' IPL.
本研究的主要目的是比较三种方法的脱毛效果：强脉冲光（IPL）、IPL与射频（RF）联合使用以及二极管激光（810nm）。
40名参与者在其腿部外侧的三个标准化区域接受治疗。每个区域治疗两次，间隔4 - 6周。第四个区域作为对照。一名不知情的医生在第一次治疗前和第二次治疗后8个月对每个区域的毛发进行计数。记录即时和延迟的副作用以及疼痛评分。
二极管激光、IPL和IPL + RF实现的平均毛发减少率分别为49.90%、39.16%和47.15%。本研究未显示任何严重副作用，且副作用数量极少。二极管激光、IPL和IPL + RF第一次和第二次治疗的平均疼痛评分分别为4.65和4.58、2.43和2.53、3.95和4.03。在研究结束时，接受双腿免费脱毛治疗的患者比例为：二极管激光20人、IPL 10人、IPL + RF 8人。
射频和光能的联合使用证明了其在脱毛方面的安全性和有效性，与二极管激光相当，且比“单纯”IPL效率高约20%。
