Usually 20 to 30, and up to 50, injections are used under the chin. The acid then works gradually to kill fat cells, which are metabolized by the body over the following weeks. The number of treatment sessions necessary varies for each person. Multiple treatments might be needed to reach optimal results.

KYBELLA® is a prescription medicine 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 the treatment of fat outside of the submental area or in children under 18 years of age.

You're probably wondering if Kybella is a temporary improvement or a permanent procedure. What you need to know is that because Kybella kills fat cells, it is considered permanent. Once the fat cells are dead, they're dead. However, you can develop new fat cells.

KYBELLA® is made of deoxycholic acid, which is an acid that is naturally produced by your body. With age, the natural production of deoxycholic acid slows, which results in your body being less efficient at absorbing fats. KYBELLA® injections are a cytolytic drug, which is used to destroy specific cells.

Once the deoxycholic acid in this injectable treatment destroys fat cells in injected areas, those fat cells will be eliminated for good, which means you should be able to enjoy permanent results.

Once the deoxycholic acid in the Kybella injections destroys your fat cells, your body will not be able to replace them with new fat cells. Therefore, the results of this treatment are considered permanent.

#3: KYBELLA Injections Are Safe. There is a small risk of nerve damage that may result in a lopsided smile or difficulty swallowing. In most cases, however, this damage is temporary and the nerves will return to normal.

Kybella is a popular alternative to surgical methods of getting rid of double chins, such as fat excision and liposuction. While these traditional methods require anesthesia and can cause bruising, infection, and scarring, by contrast, Kybella has fewer side effects and is less time-consuming.

It's important to understand that Kybella destroys fat cells, so the fat doesn't return to the treated area but can return to a new location.

In 2015 the FDA announced the approval of Kybella, which is a set of deoxycholic acid injections used to treat moderate-to-severe chin fat. Aside from its governmental approval, the agency has noted that Kybella has serious side effects such as skin and nerve damage.

If you're thinking about receiving Kybella, here are 10 side effects to keep in mind.

• Injection site pain, swelling, or numbness.
• Skin bruising.
• Headache.
• Mouth and neck pain.
• High blood pressure.
• Nausea.
• Difficulty swallowing.
• More serious injection site reactions.

Every patient is different, but in general, you should start seeing great results after just one Kybella treatment. Most patients need one or two additional Kybella treatments if they have thicker submental fat tissue.
