Cryolipolysis for fat reduction using Cooltech® Define technology: A large-sample retrospective clinical study.

Background: Cryolipolysis is a noninvasive technique for localized fat reduction, which induces selective apoptosis of the adipocytes using controlled exposure to intense cold. During the past 10 years, this technique has been shown to be safe and effective and its application has significantly increased. In this context, Cooltech® devices have been widely used around the world.

Aims: The purpose of this retrospective study was to evaluate the efficacy and safety of the removal of localized fatty tissue in different body areas using the new Cooltech® Define controlled cooling system.

Methods: This single-center study was carried out on 287 patients, both female and male, treated with Cooltech® Define on different body areas for a total of 1118 procedures. Follow-up evaluations were conducted to estimate efficacy and safety. Efficacy was evaluated through plicometry and photographs. Side effects were also reported.

Results: Fold thickness showed a significant reduction (-69.91 ± 12.55%) after cryolipolysis treatment (fold thickness before: 35.33 ± 8.41 mm; fold thickness after: 10.69 ± 5.27 mm). Few side effects were reported, they included posttreatment pain (1.70%) and one case of paradoxical adipose hyperplasia (0.09%).

Conclusion: The Cooltech® Define cryolipolysis device is a safe, effective, and well-tolerated nonsurgical procedure for reducing localized fat.
