Kybella, or deoxycholic acid, is a naturally-occurring molecule in the body that helps to break down or absorb dietary fat.

As concentrated in the injectable Kybella formula, the deoxycholic acid begins to destroy fat cells when injected into the double chin and further disables them from absorbing fat in the future in this area.

Through multiple treatments, as Kybella continues to destroy fat cells, the double chin shrinks more and more, creating an increasingly streamlined profile of the chin.
