Kybella Treatment | Tracy Evans, MD | San Francisco CA

Are you bothered by submental fullness or a double chin? Do you wish your jawline was more defined? This is a very common yet under treated 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. Patients choose to treat this area with Kybella as it is often resistant to diet and exercise alone.

What is Kybella?

Kybella is the first and only FDA-approved injectable that treats fat cells under the chin. Specifically, the area commonly referred to as a double chin. Kybella injections are a prescription medicine that contours and improves the appearance of submental fullness.

How does KYBELLA Work?

The active ingredient in Kybella, deoxycholic acid, is a naturally occurring molecule in the body. Deoxycholic acid 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.

The Double Chin Removal Process*

During a consultation with Dr. Tracy Evans, she will design a treatment plan tailored to help improve your chin profile. During the treatments, Dr. Evans will administer Kybella into the fat under your chin using multiple small injections. Based on your personal treatment plan, patients may choose to receive additional sessions for ideal results. Patients may receive up to 6 treatment sessions which our staff will schedule about 6-8 weeks apart.

After the series of treatments have been completed, you can expect less submental fat and a more defined jawline profile. Patients report their results are typically visible in 2 to 4 treatment sessions. After this time and once the desired aesthetic response is achieved, 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, self-conscious, overweight, and bothered by submental fullness.

SIDE EFFECTS of kybella Injections*

Kybella injections, similar to other cosmetic procedures and dermal fillers, can result in mild side effects. The most common include:

  • Swelling
  • Bruising
  • Pain
  • Numbness
  • Redness
  • Hardness in the treatment area

Kybella can cause more serious side effects including trouble swallowing and nerve injury that could cause an uneven smile or facial muscle weakness. Though these side effects are rare, it is important that you understand the risks of Kybella treatment. During your consultation Dr. Evans will go over these risks and side effects with you.
