Kybella is the only FDA-approved injectable treatment for reducing moderate to severe submental fat in adults. Its active ingredient, deoxycholic acid, is a naturally occurring molecule that permanently disrupts fat cell membranes when injected into the tissue beneath the chin. Unlike neurotoxins, which relax muscle movement, or fillers, which add volume, Kybella works by eliminating fat cells themselves, so results are permanent once your treatment goal is reached.
