Background: Non-invasive body contouring is a burgeoning fraction of aesthetic medicine that has engendered the emergence of numerous therapeutic devices. As more devices enter the market it becomes imperative to continually substantiate these technologies to elucidate their fundamental differences. One technology that has exhibited incipient clinical promise has been low-level laser therapy at 635 nm. Having been evaluated under the strict guidelines of a randomized, controlled study, the purpose of this independent, retrospective analysis was to discern whether the results could be replicated.

Methods: A total of 689 participants received treatment with a multi-diode low-level laser device that emitted 635nm. Patients received concurrent treatment of their waist, hips and thighs. Patients were treated every-other-day for two weeks: 6 total forty-minute treatments. Baseline waist, hip, and thigh circumferential measurements were compared with 1 week post-procedure measurements.

Results: A statistically significant mean circumferential reduction of 3.27 inch (8.31 cm) was reported for the combined waist, hips, and thighs (p<0.0001). When assessing the individual areas, a statistically significant reduction of 1.14, 0.95, and 1.18 inches was reported for the waist, hip, and thighs, respectively.

Conclusion: These data, coupled with zero reported adverse events, corroborate the clinical efficacy and safety of LLLT at 635 nm. Independent studies like this will help bolster the adoption of validated technologies.
