Kybella is an FDA-approved injectable to destroy fat in the submental or double chin area. Kybella works by decreasing the strength of the fat cell membrane, therefore, allowing the contents of fat to be released. Your body’s own healing process destroys and discards the fat. After 4-6 weeks you should see improvement and a decrease in fullness in the fatty areas that were treated. You may require multiple treatments. (2 treatments are necessary on average but maybe more or less)
