Are you bothered by submental fullness or double chin? Do you wish your jawline was more defined? This is a very 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, and is often resistant to diet and exercise alone.

What is Kybella?

Kybella (deoxycholic acid) injection is the first and only FDA-approved injectable treatment. Kybella injections are a prescription medicine used in adults that contours and improves the appearance of submental fullness, sometimes referred to as the “double chin.”

How does KYBELLA Work?

The active ingredient in Kybella, deoxycholic acid, is a naturally occurring molecule in the body that aids in the breakdown and absorption of dietary fat. When injected into the fat beneath the chin, Kybella causes the destruction of fat cells. Once destroyed, those cells cannot store or accumulate fat again.

KYBELLA Treatment*

After scheduling a consultation with Dr. Tracy Evans, we will design a treatment plan tailored to help you improve your chin profile. During the treatments, Dr. Evans will administer Kybella into the fat under your chin using multiple small injections. Many patients experience visible results in 2 to 4 treatment sessions. Up to 6 treatment sessions may be administered about 6-8 weeks apart.

If you are bothered by submental fullness, you are not alone. According to a 2015 survey conducted by the American Society for Dermatologic Surgery (ASDS), 67% of people said they’re bothered by under-the-chin fullness. The study also showed that people are just as bothered by under-the-chin fullness as they are by lines and wrinkles around and under the eyes.


After the series of treatments have been completed, you can expect less submental fat and a more defined jawline profile. Once the desired aesthetic response is achieved with Kybella, retreatment is not necessary.

79% of patients treated with Kybella reported satisfaction with the appearance of their face and chin. This includes improvement in self-perception including feeling happier and younger based on their chin profile, as well as feeling less embarrassed, less self-conscious, less overweight, and less bothered by submental fullness.
