Sick of your annoying double chin? Kybella is a non-surgical cosmetic procedure that works to reduce the appearance of fat under the chin by destroying the fat cells. This FDA-approved injectable reduces the appearance of submental fat, which is more commonly known as a double chin, and gives you a tighter, more contoured look. On average, this safe, effective treatment provides a more defined profile and visible results in 2-4 treatments. Results should be permanent.
