Why can't Kybella be used wider out on the neck? Why can it only be used right under the chin?

Thank you for your excellent question.  Kybella has been used in off label manners to address bra fat and other smaller areas of localized adiposity.  The only FDA indication for Kybella use is in the submental (below the chin) region and it is not recommended to be used wider for concerns of a temporary injury to the nerve responsible for controlling your lower lip. Hope this helps.

If the pocket of fat under your chin extends to a wider margin, Kybella is still effective and can be used.  I've also had success using Kybella off-label in other small areas of fat such as bra fat, back fat, and lipomas.Good luck!

Kybella is approved for the reduction of fat under the chin.  However, Kybella can theoretically be used anywhere there is excess fat.  However, it is usually cost-prohibitive and not predictable to use in larger areas.  Kybella has been used in the lateral fat of the neck as well as pre-bra fat with good success.  However, in off-label use, it should only be used by the most experienced of injectors due to increase risk.

Kybella can be used on the neck and jawline if there is fat. I suggest you see an expert though for the best outcomes as it is currently only approved for under the chin other areas are off label. Best,  Dr. Emer.

Kybella dissolves and kills fat cells but it also creates large amounts of inflammation. That inflammation can injure nerves that move the lower face. There is a safe area where Kybella can be placed in the middle of the chin fat pad but as you move to the outer areas beneath the jaw the risk of injuring nerves and blood vessels rises. Kybella is a safe product but please consult with an experienced physician injector that understands the product's risks. I hope this information is helpful for you.Stephen Weber MD, FACSDenver Facial Plastic Surgeon
