Kybella is an injectable treatment to treat a double chin, also known as submental fullness. It is made up of synthetic deoxycholic acid, which is a naturally occurring molecule in the body that helps with the breakdown and absorption of dietary fat. When Kybella is injected into the fat beneath the chin, it destroys excess fat cells, for long-term results. Because everyone’s chin profile is unique, the number of treatments will vary from patient to patient. However, patients should not receive more than six treatments spaced one month apart.
