Approved in April 2015, Kybella (deoxycholic acid, Allergan) generated a lot of buzz as an injectable treatment to rid adults of their double chins. So what are physicians saying about Kybella three years later?

Kybella works well for patients who need minimal fat removed and jaw line contouring, according to Walter W. Tom, M.D., a cosmetic surgeon practicing in California and Hawaii, who says he had the procedure and liked the results.

But it’s not popular among patients who have more fat and true double chins, Dr. Tom says.
