KYBELLA® is an injectable made of deoxycholic acid, which breaks down excess fat. This injectable is used to reduce submental fullness, or in other words, to eliminate a double chin. KYBELLA® can be injected into the neck area in a short, 20-minute treatment. Over the following weeks, the deoxycholic acid will break down the excess fat to produce a more slender and defined neckline. Results will become more and more noticeable over the weeks and months. After one to six treatment sessions spaced at least four weeks apart, patients can expect a permanent improvement in their neck contour.
