BACKGROUND
Some laser irradiation parameters such as wavelength, fluence, pulse duration, and spot size have been shown to influence the damage of any target inside the skin, however, the role of some patients' factors such as hair growth cycle is still under debate.
OBJECTIVE
To determine the association of treatment interval and laser treatment outcome.
METHODS
In a retrospective chart review of 176 patients undergoing laser-assisted hair removal with a diode laser 24 patients were selected. All accepted to cease the therapy, and be followed-up for 5 months. At the end of the study the patients were questioned about the efficacy of the treatment as well as the adverse effects. Hair counting was also performed. The adverse effects (pain, blister or erosion, hyperpigmentation, hypopigmentation, and folliculitis) were questioned during the follow-up period.
RESULTS
The mean hair reduction was 78.1%, 45.8%, and 28.7% in 45, 60, and 90-day interval groups, respectively (P < 0.0001).
CONCLUSION
The treatment interval was related to the treatment outcome in our study.
背景
一些激光照射参数，如波长、能量密度、脉冲持续时间和光斑大小，已被证明会影响皮肤内任何目标的损伤，然而，一些患者因素（如毛发生长周期）的作用仍存在争议。
目的
确定治疗间隔与激光治疗效果之间的关联。
方法
在一项对176例接受二极管激光脱毛治疗患者的回顾性病历审查中，选取了24例患者。所有患者均同意停止治疗，并接受5个月的随访。在研究结束时，询问患者关于治疗效果以及不良反应的情况。还进行了毛发计数。在随访期间询问了不良反应（疼痛、水疱或糜烂、色素沉着、色素减退和毛囊炎）。
结果
45天、60天和90天间隔组的平均毛发减少率分别为78.1%、45.8%和28.7%（P < 0.0001）。
结论
在我们的研究中，治疗间隔与治疗效果相关。
