Summary
Cryolipolysis effectively reduces inner thigh fat using the CoolFit applicator, with high patient satisfaction and no serious adverse events. This study supported FDA clearance for thigh treatments.
Area of Science:
- Dermatology
- Aesthetic Medicine
- Body Contouring
Background:
- Cryolipolysis, initially FDA-cleared for abdomen and flanks, showed potential for other body areas.
- Significant patient interest existed for non-surgical fat reduction in the inner and outer thighs.
Purpose of the Study:
- To evaluate the safety and efficacy of cryolipolysis for inner thigh fat reduction.
- To gather data contributing to FDA clearance for cryolipolysis treatment of thighs.
Main Methods:
- A prospective, multi-center, interventional clinical study involving 45 subjects.
- Treatment utilized a flat cup vacuum applicator (CoolFit) for 60 minutes per thigh.
- Efficacy assessed via ultrasound, circumference measurements, and photographs; safety monitored for adverse events.
Main Results:
- 42 subjects completed the 16-week follow-up.
- Ultrasound showed an average fat layer reduction of 2.8 mm.
- Circumference measurements indicated a mean reduction of 0.9 cm.
- 91% of patients reported satisfaction, and 84% observed visible fat reduction.
Conclusions:
- The CoolFit applicator demonstrated safe and effective cryolipolysis for inner thigh fat reduction.
- Study results supported the FDA clearance for cryolipolysis treatment of thighs in April 2014.
- High patient satisfaction and willingness to recommend were noted.
