Kybella, an injectable drug that contains deoxycholic acid, mostly used during mesotherapy, and now in the treatment of double chins. This treatment was approved in 2015 by the Food and Drug Administration. Deoxycholic acid enables fast absorption in your body. When the treatment is administered to your chin, it delivers the acid which dissolves the fat for absorption. You need around 3-6 treatments with one-month breaks in between to heal a double chin.
