KYBELLA® injection is the first and only FDA-approved injectable treatment that contours and improves the appearance of submental fullness, destroying fat cells. Submental fullness, sometimes referred to as “double chin”, is a common yet undertreated facial aesthetic condition. It can impact a broad range of adults, including both men and women, and can be influenced by several factors such as aging, genetics and weight gain. Submental fullness is often resistant to diet and exercise alone.
