Kybella is a nonsurgical injectable technique used to target the fat beneath the chin. The process uses a series of deoxycholic acid injections to target the fat cells in this area. No incisions are required, and the downtime is minimal in most cases. The best candidate is an adult 18 years or older with moderate to severe fat beneath the chin. You might not be a good candidate if you have had or are planning to have facial surgery, if you have trouble swallowing, are pregnant or nursing, or have an infection or medical condition in or near the planned injection site.
