Deoxycholic acid (Kybella®) – a naturally occurring molecule that permanently destroys fat cells and reduces moderate to severe fat on the upper neck. Treatment results in skin being substantially tighter and the jaw becoming more defined and contoured. Most commonly used in the FDA approved submental region to target the “double-chin.” It often requires 1-2 sessions. Best results are 3-6 months following the final session as the skin continues to tighten.
