Frequently Asked Questions
What is submental fullness?
Submental fullness is a gathering of excess fat beneath the chin, commonly known as “double chin.” It can be something you’ve had your whole life due to genetics, or start to appear as you get older or if you gain weight.
What is KYBELLA®?
KYBELLA® is a prescription medicine and is the only FDA-approved injectable treatment used in adults to improve the appearance and profile of moderate to severe fat below the chin (submental fat), also called “double chin.” It is not known if KYBELLA® is safe and effective for use outside of the submental area or in children less than 18 years of age.
How does KYBELLA® work?
The active ingredient in KYBELLA® is synthetic deoxycholic acid. 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® destroys fat cells, and once destroyed, these cells can no longer store or accumulate fat. This results in a noticeable reduction in fullness under the chin, revealing an improved chin profile.
How is KYBELLA® administered?
Treatment can only be administered by a KYBELLA®-trained healthcare specialist. At each treatment, you will receive multiple small injections under your chin, and the injection process takes about 15 to 20 minutes. The exact number of injections will depend on the amount of fat you have under your chin and your desired profile.
How many KYBELLA® treatment sessions will I need?
Since everyone’s chin profile is different, the number of treatments varies from patient to patient. Your healthcare specialist will help determine how many treatment sessions you need based on the amount and distribution of your submental fat and your personal treatment goals. Each KYBELLA® treatment session is given at least 1 month apart, and you should not receive more than 6 treatments. In clinical studies, 59% of patients received 6 treatments.
How long will results last?
When injected into fat under the chin, KYBELLA® causes the destruction of fat cells. Once destroyed, those cells cannot store or accumulate fat. After reaching your desired aesthetic, further treatment is not expected.
Will I need time to recover?
After KYBELLA® treatment, you will likely have some swelling, bruising, or numbness under your chin. Be sure to inform your healthcare professional if you develop an uneven smile, facial muscle weakness, or difficulty swallowing.
What are the possible side effects of KYBELLA®?
KYBELLA® can cause serious side effects, including nerve injury in the jaw that can temporarily cause an uneven smile or facial muscle weakness (experienced by 4 out of 100 people in clinical studies) and trouble swallowing (experienced by 2 out of 100 people in clinical studies). In clinical studies, nerve injury in the jaw resolved on its own in a median of 44 days (range of 1 to 298 days), and trouble swallowing resolved on its own in a median of 3 days (range of 1 to 81 days).
The most common side effects of KYBELLA® include swelling, bruising, pain, numbness, redness, and areas of hardness in the treatment area. Side effects are usually temporary and often resolve on their own.
What should I tell my doctor before treatment?
Before receiving KYBELLA®, tell your healthcare provider about all of your medical conditions, including if you:
- Have had or plan to have surgery on your face, neck, or chin
- Have had cosmetic treatments on your face, neck, or chin
- Have had or have medical conditions in or near the neck area
- Have had or have trouble swallowing
- Have bleeding problems
- Are pregnant or plan to become pregnant (it is not known if KYBELLA® will harm your unborn baby)
- Are breastfeeding or plan to breastfeed (it is not known if KYBELLA® passes into your breast milk; talk to your healthcare provider about the best way to feed your baby if you receive KYBELLA®)
- Are taking any medications, especially blood thinners
