Double chin, or submental fullness, is a common, yet undertreated facial aesthetic condition. Submental fullness is not limited to people who are overweight and is often resistant to diet and exercise. It can affect men or women of average weight and can be caused by aging, genetics and weight gain. Submental fullness can make those affected seem heavier than they are and lead to an older, unbalanced facial appearance. In the past treatment for submental fullness was limited to invasive options like surgery and liposuction or energy devices that offered inconsistent and temporary results.
