Kybella is an FDA-approved injectable that improves the appearance of double chins by destroying fat cells. Kybella is made form of deoxycholic acid, a naturally occurring material that helps the body absorb fat. Kybella destroys the membranes of the cells that store fat.  Once these cells are destroyed, they can no longer store fat. The body’s natural healing and elimination processes take over, and in about four to six weeks, your fat deposits are dramatically reduced or eliminated.
