The use of non-ablative fractionated lasers for skin rejuvenation has been proven to be effective in improving skin texture, and has become popular due to minimal wounding, significantly shorter recovery times and decreased adverse effects.
To retrospectively analyze improvement in skin texture in healthy women aged over 18 years with Fitzpatrick skin types II-IV.
Participants received three facial and/or neck treatments with the 1570-nm fractional scanning diode laser at 1-month intervals. Three months after the last treatment session two blinded evaluators assessed skin improvement using before and after photos. Pain and patient satisfaction were recorded.
Sixteen women with a mean age of 45.4 ± 4.1 years (range 35-50 years) and skin type II-IV were included in the analysis. All 16 participants received facial treatments and seven (43.8%) also received neck treatments. Three months follow-up evaluation showed that the majority of participants had a visible change in the treated areas. Mean pain score was low and decreased with each treatment session.
Skin treatment using fractional scanning 1570-nm diode laser improves skin laxity in women with skin types II-IV. Larger studies are warranted to further clarify the efficacy and safety of this modality.
非剥脱性分段式激光用于皮肤年轻化已被证明在改善皮肤质地方面有效，因其创伤极小、恢复时间显著缩短和不良反应减少而受到欢迎。
回顾性分析 18 岁以上、Fitzpatrick 皮肤类型 II-IV 的健康女性皮肤质地的改善情况。
参与者在 1 个月的间隔内接受 3 次面部和/或颈部 1570nm 分段扫描二极管激光治疗。末次治疗后 3 个月，两名盲法评估者使用治疗前后的照片评估皮肤改善情况。记录疼痛和患者满意度。
16 名平均年龄为 45.4±4.1 岁（范围 35-50 岁）、皮肤类型 II-IV 的女性被纳入分析。所有 16 名参与者均接受了面部治疗，7 名（43.8%）还接受了颈部治疗。3 个月随访评估显示，大多数参与者的治疗区域有明显变化。平均疼痛评分较低，并随每次治疗而降低。
使用分段扫描 1570nm 二极管激光进行皮肤治疗可改善 II-IV 型皮肤女性的皮肤松弛。需要更大的研究进一步阐明该方法的疗效和安全性。
