The non-invasive body-contouring segment continues to exhibit uninhibited growth, a trend that has provoked the emergence of numerous body-contouring devices. One particular device, low-level laser therapy at 635 nm (LLLT-635), has exhibited promising clinical results. We performed an independent, physician-led trial to evaluate the utility of LLLT-635 nm for non-invasive body contouring of the waist, hips, and thighs.
Eighty-six participants were retrospectively assessed at an individual clinic in the United States. A multi-head laser device was administered every-other-day for 2 weeks. Each treatment consisted of 20 minutes of anterior and posterior treatment. Patients received concurrent treatment of the waist, hips, and bilateral thighs. Circumferential measurements were evaluated at baseline and one week following the 2-week treatment administration phase.
Compared with baseline, a statistically significant 2.99 in. (7.59 cm) mean loss was observed at the post-procedure evaluation point (P < 0.0001). When analyzed individually, the waist, hips, and thighs each reported a statistically significant reduction of -1.12, -0.769, and -1.17, respectively. Furthermore, linear regression analysis revealed a weak linear dependence (r = 0.179) between the reported weight and circumference change.
These data further validate the clinical efficacy and safety of LLLT at 635 nm.
非侵入性身体塑形领域持续呈现出不受抑制的增长态势，这一趋势促使众多身体塑形设备应运而生。其中一款特定设备，即635纳米低强度激光疗法（LLLT - 635），已展现出颇具前景的临床效果。我们开展了一项由医生主导的独立试验，以评估LLLT - 635纳米用于腰部、臀部和大腿非侵入性身体塑形的效用。
在美国的一家个体诊所对86名参与者进行了回顾性评估。使用多头激光设备，每隔一天治疗一次，持续2周。每次治疗包括前后各20分钟。患者同时接受腰部、臀部和双侧大腿的治疗。在基线以及为期2周的治疗给药阶段结束后一周评估周长测量值。
与基线相比，在术后评估点观察到平均减少2.99英寸（7.59厘米），具有统计学意义（P < 0.0001）。单独分析时，腰部、臀部和大腿的减少量分别具有统计学意义，分别为 - 1.12、 - 0.769和 -
