Kybella is made up of synthetic deoxycholic acid. Deoxycholic acid is a naturally occurring molecule in the body that aids in the breakdown and absorption of dietary fat. When injected into the fat beneath the chin, kybella destroys fat cells, resulting in a noticeable reduction in fullness under the chin. Once destroyed, these cells can no longer store or accumulate fat, so further treatment is not expected once you reach your desired aesthetic goal.
At each treatment, you will receive multiple small injections under your chin, the exact number of injections will depend on the amount of fat you have under your chin and your desired profile. The number of treatments also varies as each individuals profile is different as well as their aesthetic goals.
