According to a 2015 survey by the American Society for Dermatologic Surgery (ASDS), 67% of people are bothered by the excess fat beneath their chin.  Submental fullness due to fat can be caused by genetics, weight gain, and again—and even with diet and exercise, that unwanted fullness beneath the chin won’t always go away. 

Kybella (deoxycholic acid) is the first and only FDA-approved injectable treatment to improve the appearance of moderate to severe fat beneath the chin.  It works by physically destroying fat cells and, once destroyed, those cells can no longer store or accumulate fat.

79% of people treated with Kybella had improved satisfaction with the appearance of the area beneath their chin (compared with 34% of people treated with placebo) 12 weeks after their last treatment.

Kybella patients reported improvement in the visual and emotional impact of submental fat when asked how happy, bothered, self-conscious, embarrassed, old, and overweight they felt with respect to the amount of their submental fat after they received treatment.

Kybella is a series of injections administered over the course of two to six visits, with the visits spaced four to six weeks apart.

The most common side effects include swelling, bruising, pain, numbness, redness, and areas of hardness around the treatment site.  Other potential side effects include nerve jaw injury, which can cause an uneven smile or facial muscle weakness, and trouble swallowing.
