Whether Kybella is right for you or not is a question of what is behind your double chin. Double chins can form due to fat deposits weighing down the skin, or they can form from excess, sagging skin. If fat deposits are the cause of your double chin, Kybella is perfect for you. However, if your double chin is more a factor of sagging, loose skin, you’d be better off with surgery to remove the excess skin and tighten the underlying support tissue.
