Open-label study demonstrates greater circumference reduction using violet laser versus red laser.
Background: This brief report presents the clinical findings of recent advancements that led to the first FDA market clearance utilizing violet laser for the achievement of body circumference reduction (K231474). Objective: The study was open-label singe arm design to evaluate the efficacy of the violet laser to that of application of the precursor red laser. Methods: The study procedure was identical to that evaluated in the comparative red laser study, with the difference being the reduction in per-treatment time from 40 minutes (red laser) to 20 minutes (violet laser). Results: The mean circumference reduction was 3.91 inches, which is greater than the mean change of 3.72 inches attained in the compartive red laser application. Conclusion: The study establishes the efficacy of violet laser as a viable treatment option for non-invasive body circumference reduction. The violet laser's higher photonic energy translates to clinically meaningful outcomes achieved in half the treatment time compared to the precursor red laser (NCT05674292).
