What is Kybella?

Kybella (deoxycholic acid) is a manmade form of a substance your body makes that helps to absorb fats. Deoxycholic acid works by destroying fat cells where it is injected into the body.

Kybella injection is used to help decrease the appearance of fat that hangs below the chin, sometimes called a double-chin.

Kybella has not been tested for safe use on other areas of the body.
