Clinical evaluation of the safety and efficacy of a 1060 nm diode laser for non‐invasive fat reduction of the flanks

Abstract

AbstractBackgroundLaser hyperthermia‐induced lipolysis is a non‐invasive method of localized fat treatment. Non‐invasive approaches could be an option for a growing number of patients who are risk‐averse and are seeking out non‐invasive alternatives to surgical procedures such as liposuction. This study evaluated the safety and efficacy of a 1060 nm diode laser for the non‐invasive fat reduction of the flanks.MethodsA total of 30 subjects were enrolled in this prospective, single center study. Subjects received one 25‐min treatment with a 1060 nm diode laser to both flanks. Follow‐up visits were conducted at 6 and 12 weeks after the last treatment. Ultrasound adipose thickness, body weight, and circumference measurements were taken at baseline and at the 6‐ and 12‐week follow‐up visits. Subject satisfaction was assessed using a self‐assessment of fat reduction, pain, and tolerability scales, and a subject satisfaction questionnaire. Safety was assessed via the presence or absence of any adverse events.ResultsThe average age of subjects was 47.3 years. A total of 27 subjects completed the treatment and returned for both follow‐up visits. An adipose reduction of 7.57 ± 1.15% at 6 weeks post‐treatment (p < 0.0001) was measured using ultrasound. High subject satisfaction was seen, with 74% of subjects reporting being either “satisfied” or “very satisfied” with their results on a 5‐point Likert Scale. Eighty‐two percent of subjects stated they would recommend the treatment to their friends. All subjects had either mild or moderate pain, with 52% of subjects rating their pain as “mild” (1–3), while 48% rated their pain as moderate (4–7) on the Wong‐Baker Scale.ConclusionsA single treatment with a 1060 nm diode laser was both safe and effective in reducing unwanted fat in the flanks without any unanticipated adverse events. Subjects described their treatment pain as mild or moderate and were highly satisfied with their treatment outcomes.
