Noninvasive body shaping is becoming a growing demand. The aim of this study was to investigate the efficacy and safety of the combined treatments of 1064 nm Nd:YAG and 2940 nm Er:YAG in noninvasive lipolysis and skin tightening. Ten females were enrolled, and all women's side of the waist or the lower part of the abdomen were treated. In the first step, the 1064 nm Nd:YAG was used. As a second step, the 2940 nm Er:YAG laser was applied. Each woman was treated four times, once every 2 weeks. The effects were determined by comparative photo documentation, waist circumference measurement, two‐dimensional B‐mode ultrasonography and low‐dose native computer tomography (CT), whereas body fat was monitored with bioelectric impedance. The tissue firmness was measured by ultrasound shear wave elastography. Combined laser treatment significantly reduced waist circumference and total body fat. Ultrasonography has revealed that the treatment considerably decreased fat thickness and improved skin stiffness in the treated region. Subcutaneous fat volume, measured by low‐dose CT, displayed a moderate decrease in the waist region. The combined 1064 nm Nd:YAG and 2940 nm Er:YAG laser treatment results in the reduction of fat tissue and tightens the skin as confirmed by objective measurements.

长脉冲1064和2940 nm激光在非侵入性脂肪分解和皮肤收紧中的功效和安全性。
非侵入式塑身正成为日益增长的需求。这项研究的目的是研究1064 nm Nd：YAG和2940 nm Er：YAG联合治疗在非侵入性脂解和皮肤紧缩中的功效和安全性。招募了十名女性，对所有女性的腰部或腹部下部进行了治疗。第一步，使用1064 nm Nd：YAG。第二步，使用2940 nm Er：YAG激光器。每个妇女接受四次治疗，每2周一次。效果由比较的照片记录，腰围测量，二维B型超声检查和低剂量本机计算机断层扫描（CT）确定，而体内脂肪则通过生物电阻抗监测。通过超声剪切波弹性成像法测量组织硬度。联合激光治疗可显着减少腰围和全身脂肪。超声检查表明，该治疗显着降低了治疗区域的脂肪厚度并改善了皮肤僵硬。通过低剂量CT测量的皮下脂肪量显示腰部区域有中等程度的减少。客观测量结果证实，组合的1064 nm Nd：YAG和2940 nm Er：YAG激光治疗可减少脂肪组织并收紧皮肤。
