Kybella is the first FDA approved a non-surgical injectable for reducing moderate to severe fat on the upper neck, otherwise known as a “double chin. Kybella is deoxycholic acid, a fat-absorbing substance found in our bodies naturally. When injected, it destroys fat cells under the chin, which are reabsorbed by the body leaving the skin substantially tighter and the jaw more contoured. The procedure is non-invasive with minimal downtime or recovery required. Most treatments last between 15 and 20 minutes. Lidocain (a topical numbing anesthetic) can be used to minimize discomfort. Results depend on the amount of excess fat patient have under the chin. Most patients begin seeing results 3-4 weeks post injection. Many patients treated with KYBELLA™ experience visible contouring of their chin profile in 2 to 4 treatments (spaced at least one month apart). Some people require up to 6 treatments in order to achieve results. Once the aesthetic response is achieved no further treatments will be required unless submental fullness redevelops. The safety and effectiveness of Kybella were established in two large studies, which enrolled over 1,000 adult participants with moderate or severe submental fat. The participants who received Kybella (for up to six treatments) instead of a placebo (non-Kybella) more frequently saw reductions in fat and improved jawline/neckline contour.
Kybella can cause serious side effects (temporarily), including nerve injury in the jaw that can cause an uneven smile or facial muscle weakness, and trouble swallowing. The most common side effects of Kybella include swelling, bruising, pain, numbness, redness and areas of hardness in the treatment area. These side effects are also the most common side effects seen with Botox injections or dermal fillers like Juvederm and Restylane.
