Owing to skin aging and the growing demand for skin rejuvenation, minimal invasive aesthetic treatments such as laser procedures are increasingly coming into focus. However, until now, little has been known about the objective effects of these procedures with respect to skin microcirculation or changes in skin elasticity.
Facial skin rejuvenation was performed on 32 volunteers using ablative Erbium: YAG laser. Skin microcirculation and skin elasticity have then been evaluated objectively.
Microcirculation (flow, SO , velocity, and rHB) has been analyzed before and directly after the laser session by using the O2C device. Skin elasticity has been evaluated by using the Cutometer device (Uf, Ua, Ur, and Ue) before and directly after the laser treatment, as well as 1 week and then 1, 3, and 6 months post treatment. Further, the outcome for the volunteers regarding their satisfactory level after laser treatment was evaluated.
Twenty volunteers were available for a complete follow-up. Microcirculation displayed statistically significant increase in all values to 2 mm depth. The biomechanical skin parameter of firmness of skin displayed statistically significant improvement in superficial skin layer after 6 months.
Concerning microcirculation and skin elasticity the ablative Erbium: YAG laser treatment revealed similar effects on the skin like a superficial burn injury. In contrast to the determined skin elasticity parameters, firmness of skin objectively revealed a skin tightening effect after 6 months. Along with the important epidermal effect, the suitability of ablative laser treatment for skin rejuvenation has been proved in a long-term follow-up. Lasers Surg.

由于皮肤老化以及对皮肤年轻化的需求不断增加，诸如激光手术等微创美容治疗日益受到关注。然而，迄今为止，对于这些手术在皮肤微循环或皮肤弹性变化方面的客观效果知之甚少。
对32名志愿者使用剥脱性铒：钇铝石榴石激光进行面部皮肤年轻化治疗。然后对皮肤微循环和皮肤弹性进行客观评估。
使用O2C设备在激光治疗前及治疗后即刻分析微循环（血流量、血氧饱和度、血流速度和相对血红蛋白含量）。在激光治疗前及治疗后即刻、治疗后1周、1个月、3个月和6个月使用皮肤弹性测定仪（Uf、Ua、Ur和Ue）评估皮肤弹性。此外，评估志愿者对激光治疗后满意度的结果。
20名志愿者可进行完整随访。在2毫米深度处，所有微循环值均显示出统计学上的显著增加。6个月后，皮肤紧致度的生物力学皮肤参数在表皮浅层显示出统计学上的显著改善。
关于微循环和皮肤弹性，剥脱性铒：钇铝石榴石激光治疗对皮肤的影响类似于浅表烧伤。与所测定的皮肤弹性参数不同，皮肤紧致度在6个月后客观上显示出皮肤紧致效果。除了重要的表皮效应外，剥脱性激光治疗在长期随访中已被证明适用于皮肤年轻化。《激光外科与医学》49:891 - 898，2017年。©2017威利期刊公司
