Kybella is an FDA-approved injectable that improves the appearance of double chins by permanently destroying fat cells.
 
Kybella is a man-made form of deoxycholic acid, a naturally occurring material that helps the body absorb fat. Treatment with Kybella is fast, requires little downtime, and destroys fat cells permanently. 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.
 
In clinical trials used by the FDA, even those patients who gained weight after Kybella injectables did not see their fatty areas return.
 
You'll need at least 2-4 sessions 4-6 weeks apart to get optimal results.
