Cryolipolysis for submental fat reduction in Asians.

[BACKGROUND] Cryolipolysis is a noninvasive method for the selective reduction of fat, especially proven to be safe and effective in body contouring. There is a demand for reduction in submental fat, which is related not only with a favorable appearance but also with signs of aging.

[OBJECTIVE] This study evaluated the efficacy and safety of cryolipolysis for subcutaneous fat reduction in the submental area in Asians.

[MATERIALS AND METHODS] Ten healthy Koreans were treated using a cryolipolysis contact device (CoolMini applicator, Zeltiq Aesthetics). The device was applied on the participant's neck twice via two lateral approaches. Patient's body weight was measured, and photographs were taken at baseline and during the follow-up visit after 8 weeks. Participants were examined with ultrasound and the depth of the subcutaneous fat layer was measured.

[RESULTS] The subjective reduction of submental fat was noted in most of the participants. Reduction of the subcutaneous fat layer depth was confirmed by ultrasound after 8 weeks of treatment.

[CONCLUSION] The results of this study indicate that submental fat can be safely and effectively reduced with use of a cryolipolysis applicator. The present study shows that cryolipolysis can be an option for nonsurgical facial contouring.
