High-fluence diode lasers with contact cooling have emerged as the gold standard to remove unwanted hair. Lowering the energy should result in less pain and could theoretically affect the efficacy of the therapy.
To compare the safety and efficacy of a low fluence high repetition rate 810-nm diode laser to those of a high fluence, low repetition rate diode laser for permanent axillary hair removal in Chinese women.
Ninety-two Chinese women received four axillae laser hair removal treatments at 4-week intervals using the low fluence, high repetition rate 810-nm diode laser in super hair removal (SHR) mode on one side and the high fluence, low repetition rate diode laser in hair removal (HR) mode on the other side. Hair counts were done at each follow-up visit and 6-month follow-up after the final laser treatment using a "Hi Quality Hair Analysis Program System"; the immediate pain score after each treatment session was recorded by a visual analog scale.
The overall median reduction of hair was 90.2% with the 810-nm diode laser in SHR mode and 87% with the same laser in HR mode at 6-month follow-up. The median pain scores in SHR mode and in HR mode were 2.75 and 6.75, respectively.
Low fluence, high repetition rate diode laser can efficiently remove unwanted hair but also significantly improve tolerability and reduce adverse events during the course of treatment.
带有接触式冷却的高能量密度二极管激光器已成为去除多余毛发的金标准。降低能量应会减少疼痛，并且从理论上讲可能会影响治疗效果。
比较低能量密度、高重复频率810纳米二极管激光器与高能量密度、低重复频率二极管激光器对中国女性永久性腋毛去除的安全性和有效性。
92名中国女性接受了4次腋部激光脱毛治疗，每隔4周进行一次，一侧使用低能量密度、高重复频率810纳米二极管激光器的超脉冲脱毛（SHR）模式，另一侧使用高能量密度、低重复频率二极管激光器的脱毛（HR）模式。每次随访以及最后一次激光治疗后6个月随访时，使用“高品质毛发分析程序系统”进行毛发计数；每次治疗后立即使用视觉模拟量表记录疼痛评分。
在6个月随访时，810纳米二极管激光器SHR模式下毛发总体减少中位数为90.2%，HR模式下为87%。SHR模式和HR模式下的疼痛评分中位数分别为2.75和6.75。
低能量密度、高重复频率二极管激光器能够有效去除多余毛发，还能显著提高耐受性并减少治疗过程中的不良事件。
