Kybella Treatment is an FDA-approved injectable treatment designed to reduce submental fat, commonly known as a double chin. After a Kybella treatment, some patients experience Kybella swelling in the treated area, which typically subsides within a few days. It contains deoxycholic acid, a naturally occurring substance that helps break down and absorb dietary fat. By targeting and destroying fat cells under the chin, Kybella helps contour and enhance the profile of your neck and jawline. Kybella Cost varies depending on the number of sessions required and the clinic’s pricing.
