KYBELLA FAQ

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.

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.

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.

Your specialist will create a tailored treatment plan based on your chin profile. At each treatment, you will be given multiple small injections under your chin. You may receive up to 6 treatment sessions, spaced at least 1 month apart. Many patients experience visible results in 2 to 4 KYBELLA® treatments. 59% of patients received 6 treatments in clinical studies.
In clinical studies, results for KYBELLA®-treated patients who had

• A ≥1-grade composite combined physician- and patient-rated improvement were 8% (1 treatment), 28% (2 treatments), 43% (3 treatments), 55% (4 treatments), 66% (5 treatments) and 72% (6 treatments), compared with 2% (1 treatment), 7% (2 treatments), 12% (3 treatments), 14% (4 treatments), 15% (5 treatments), and 22% (6 treatments) of patients treated with placebo
• A ≥2-grade composite combined physician- and patient-rated improvement were 0% (1 treatment), 0.2% (2 treatments), 0.8% (3 treatments), 3.5% (4 treatments), 3.9% (5 treatments) and 15% (6 treatments) compared with 0% (1 treatment), 0.2% (2 treatments), 0.2% (3 treatments), 0.5% (4 treatments), 0.2% (5 treatments), and 1.5% (6 treatments) of patients treated with placebo

KYBELLA® can cause serious side effects, including injection site problems such as bruising, hair loss, open sores (ulcers), and damage and tissue cell-death (necrosis) around the injection site or trouble swallowing and nerve injury in the jaw that can temporarily cause an uneven smile or facial muscle weakness. 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 are swelling, bruising, pain, numbness, redness and areas of hardness around the treatment area. These are not all of the possible side effects of KYBELLA®. Call your healthcare provider if you develop open sores or drainage from the treatment area or for medical advice about side effects.

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.
