Kybella is an FDA-approved injectable treatment for moderate to severe fat beneath the chin in adults. It contains synthetic deoxycholic acid, which destroys targeted fat cells so they can be naturally cleared by the body.

Once Kybella destroys treated fat cells, those cells can no longer store or accumulate fat. However, maintaining a stable weight remains important because untreated fat cells in the surrounding area can still change in size.

The number of treatments varies based on the amount of submental fat and your desired results. Your provider will create a personalized treatment plan during your consultation rather than using the same number of sessions for every patient.

Swelling beneath the chin is common after Kybella and can be noticeable, particularly after the first treatment. Bruising, tenderness, redness, numbness or firmness may also occur temporarily. Your provider will review expected recovery and aftercare before treatment.

Kybella may be appropriate for adults with unwanted fat beneath the chin who prefer a non-surgical treatment. Because fullness can also be caused by loose skin or facial structure, a consultation is important to determine whether Kybella is the right option for your concern.
