A review of research for a cryolipolysis technology

Abstract

AbstractBackgroundObesity and excess body fat are known health issues and a major aesthetic concern. Numerous modalities have been developed to address unwanted deposits of adiposity, including the development of various noninvasive methods overcoming the limitations and risks of invasive alternatives. Cryoadipolysis, also known commonly as cryolipolysis, involves the harnessing of selective cryolysis, the selective cold‐based damaging of subcutaneous fat cells which die via apoptosis, and are removed naturally by the body over time.AimsTo provide a brief but comprehensive summary of the literature supporting two related cryoadipolysis devices that are only available outside of North America, Cooltech and Cooltech Define (Sinclair).Results/DiscussionReview of 10 available clinical studies evaluating the two devices, specifically, showed both devices to be safe, with side effects profiles comparable to those of similar platforms in the armamentarium. Both operate by non‐invasively lowering the temperature of localized subcutaneous fat and maintaining it at or below a threshold that causes disruption of adipocytes via crystallization, inducing apoptosis (programmed cell death). Over time, clinically significant reductions in fat thickness and circumference of the treated area were noted. Patient satisfaction is high. The literature also highlights the necessity of adherence to patient selection and device use guidelines to minimize potential for rare paradoxical adipose hyperplasia and maximize patient satisfaction.
