: Lasers and IPL action are similarly based on the selective photo thermolysis principle, where melanin acts as chromatophore. There are, however, fundamental differences in the way they are built and in the light they emit.The goal of this paper is to compare the results of epilation treatments by laser and by IPL and to rate the effectiveness of diode laser epilation following non-coherent light therapy.: 45 healthy females, 21-23 years old, skin type II-III took part in the study.805 nm diode laser and IPL device with a wavelength of 640-1200 nm, was used. The informed consent for participation and treatment was obtained during consultation. The participants were randomly divided into three groups of 15: I - one IPL treatment followed by three diode laser treatments, II - two IPL treatments followed by three diode laser treatments, III- three IPL treatments followed by three diode laser treatments.: A percentage average of hair loss among patients treated with diode laser as a control group is higher which indicates laser's higher effectiveness. IPL has been shown to negatively impact the effectiveness of diode laser. This is linked with the way non-coherent light weakens and thins the hair that impedes the absorption of laser light by melanin and adversely affects treatment results.
激光和强脉冲光（IPL）的作用同样基于选择性光热解原理，其中黑色素作为色素团。然而，它们的构造方式和发出的光存在根本差异。本文的目的是比较激光脱毛和强脉冲光脱毛的治疗结果，并评估非相干光治疗后二极管激光脱毛的效果。45名年龄在21至23岁、皮肤类型为II - III型的健康女性参与了该研究。使用了波长为805nm的二极管激光和波长为640 - 1200nm的强脉冲光设备。在咨询过程中获得了参与和治疗的知情同意书。参与者被随机分为三组，每组15人：第一组 - 一次强脉冲光治疗后进行三次二极管激光治疗，第二组 - 两次强脉冲光治疗后进行三次二极管激光治疗，第三组 - 三次强脉冲光治疗后进行三次二极管激光治疗。作为对照组，接受二极管激光治疗的患者平均脱发百分比更高，这表明激光的效果更好。已证明强脉冲光会对二极管激光的效果产生负面影响。这与非相干光使毛发变细变软从而阻碍黑色素对激光的吸收并对治疗结果产生不利影响的方式有关。
