Laser hair removal (LHR) has become one of the most popular treatments in aesthetics. Side effects are an inevitable part of laser therapy, therefore managing them is crucial for every laser practitioner to ensure patients' safety along with achieving the best results. The available references describe the effectiveness of the diode LHR for all skin types according to the Fitzpatrick scale, but the question of patient safety and minimization of side effects and postoperative complications in mixed-race patients remains unanswered. This study aims to illustrate aspects of specific side effects in patients of mixed ethnicity and the impact of those effects on the results of the treatment. The study was conducted in Poland and the United Kingdom on 216 patients of various ethnic backgrounds. This study analyses the frequency of side effects in a mixed-race group of 32 participants, taking into account their skin type according to the Fitzpatrick scale. The patients received a course of 6 treatments using diode laser 805 nm. An objective and a subjective method were used to analyse treatment results and side effects, with adverse effects documented, if observed. Treatment settings were adjusted to skin reaction during the patch test. Objective analysis was different from the subjective analysis of the treatment's effectiveness. No adverse effects were observed. Side effects such as hyperpigmentation, skin irritation, skin burns, and skin hypersensitivity were found. 805 nm diode laser is effective and efficient at hair removal in mixed-race patients. It is a safe treatment in terms of skin reaction as only short-term side effects were observed in the treated area and no adverse effects were noted. To achieve the best results and to avoid adverse effects it is necessary to adjust treatment settings according to the individual patient's skin reaction.
激光脱毛（LHR）已成为美容领域最受欢迎的治疗方法之一。副作用是激光治疗不可避免的一部分，因此，对于每位激光从业者来说，管理副作用对于确保患者安全并取得最佳效果至关重要。现有参考文献描述了二极管激光脱毛针对菲茨帕特里克皮肤分型的所有皮肤类型的有效性，但混血患者的患者安全以及副作用和术后并发症最小化的问题仍未得到解答。本研究旨在阐述混血患者特定副作用的相关方面以及这些副作用对治疗结果的影响。该研究在波兰和英国对216名不同种族背景的患者进行。本研究分析了32名参与者的混血组中的副作用发生频率，并根据菲茨帕特里克皮肤分型考虑了他们的皮肤类型。患者接受了6次使用805nm二极管激光的治疗疗程。采用客观和主观方法分析治疗结果和副作用，如有观察到不良反应则进行记录。在光斑测试期间根据皮肤反应调整治疗参数。客观分析与对治疗效果的主观分析不同。未观察到不良反应。发现了色素沉着、皮肤刺激、皮肤灼伤和皮肤过敏等副作用。805nm二极管激光在混血患者的脱毛方面有效且高效。就皮肤反应而言，这是一种安全的治疗方法，因为在治疗区域仅观察到短期副作用，未发现不良反应。为了取得最佳效果并避免不良反应，有必要根据个体患者的皮肤反应调整治疗参数。
