Kybella, deoxycholic acid, is a naturally occurring substance in the body that is produced to help digest dietary fat. In aesthetics, it has been found to be useful to permanently remove unwanted fat cells in the chin area. However, while Kybella has been FDA approved for use in treating “double-chin”, it is commonly used used in other areas as well. Treatment usually involves a series of 2-6 injections 4 weeks apart.
