Body Contouring Using Low Level Laser Therapy
Mark S. Nestor, MD, PhD, Jessica Newburger, DO, and Matthew B. Zarraga, DO
Striving for a youthful appearance has become so important in Western society that even small imperfections on the body are now scrutinized. Tissue laxity and generalized and localized subcutaneous fat deposits are increasingly common complaints among cosmetic patients. As a result, the number of procedures performed for body contouring has increased exponentially. Chronologic aging, photoaging, or substantial changes in body dimensions experienced during pregnancy or weight loss can all contribute to the formation of localized and generalized fat deposits as well as lax skin.1,2
From the advent of liposuction in the late 1970s and early 1980s, the practice of body contouring has seen the growth of more effective and less risky liposuction techniques, and has evolved in the direction of minimally invasive procedures.
Independent Evaluation of Low-Level Laser Therapy at 635 nm for Non-Invasive Body Contouring of the Waist, Hips, and Thighs

Introduction: The non-invasive body-contouring segment continues to exhibit uninhibited growth, a trend that has provoked the emergence of numerous bodycontouring 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.
Methods: Eighty-six participants were retrospectively assessed at an individual clinic in the United States. A multi-head laser device was administered every-otherday 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. Results: Compared with baseline, a statistically significant 2.99 in. (7.59 cm) mean loss was observed at the post-procedure evaluation point . When analyzed individually, the waist, hips, and thighs each reported a statistically significant reduction of 1.12, 0.769, and 1.17, respectively. READ MORE
