Kybella is the go-to treatment for people who want to get rid of a stubborn double chin. It’s an FDA-approved injectable, and its active ingredient is synthetic deoxycholic acid, which is a naturally occurring substance in the human body.
Once injected into the fat beneath the chin, Kybella starts to destroy fat cells, resulting in a noticeable reduction of a double chin. The exact number of injections you will need will depend, however, on the amount of fat under your chin.
Once you finish the treatment, the destroyed cells are gone for good. So long as you maintain a healthy lifestyle, there’s no need for further treatment afterwards.
