Kybella is a great option for non-invasive fat reduction under the neck; however, effectiveness depends on a lot of factors including the amount of fat, the position of the fat, the amount of product injected and the skin quality of the area treated. In general, kybella works best in patients with a small amount of fat localized under the chin. For larger amounts of fat, more treatments and more volume of Kybella need to be used often making it costly. In the studies most patients had 4-6 treatments. Return to your physician and have an open conversation about your results and expectations; it may be that you need more treatments or a different approach. Best of luck.
