What is Kybella? January 24, 2023 Kybella® is an injectable cosmetic treatment that helps patients get rid of their double chin once-and-for-all by melting away submental fat. Kybella® gives patients a non-surgical and minimally invasive alternative to more invasive facial contouring procedures – such as neck liposuction – while yielding the same, potentially permanent results. Kybella®’s active ingredient, deoxycholic acid, simply melts away targeted fat which is naturally eliminated from the body following treatment. This leaves patients with a beautifully contoured and slimmed appearance without the downtime and recovery period that comes with traditional facial contouring methods.
