KYBELLA® (deoxycholic acid) is used for the treatment of submental fullness (double chin). Deoxycholic acid is a naturally occurring molecule in the body. Bile acids (including deoxycholic acid) are produced in the liver and stored in the gallbladder. Bile is released into the small intestine after a meal to metabolize dietary fat. The active ingredient in KYBELLA® is a synthetic form of deoxycholic acid and, in aesthetic medicine, it is used to metabolize unwanted subcutaneous fat. When a KYBELLA®-trained injector injects into the fat beneath the trouble area, KYBELLA® destroys fat cells, resulting in a noticeable reduction in fullness. Because we are born with a fixed number of fat cells and do not make or destroy them naturally, the cells do not regenerate in the area that was injected. Once the patient reaches their desired aesthetic outcome, further treatment is not necessary as the results are permanent.
