What is Kybella®?

Kybella is the first injectable treatment used for the reduction of submental fullness caused by excess fat under the chin and neck. Kybella injections are performed in a series of treatments to reduce the excess fat over time, effectively dissolving the fat, which your body slowly removes. The main ingredient in Kybella is a substance called deoxycholic acid. This active ingredient helps them to break down and absorb the fat cells to be flushed out of the body over time. With a series of treatments, patients can experience a noticeable reduction in fullness and may even see some mild tightening of the skin.

Who is a Candidate?

Anyone who is bothered by the appearance of a double chin can benefit from this injection. However, this treatment is intended for those who have excess fat causing the fullness and not loose skin. Loose skin in the absence of excess fat cannot be treated by Kybella. Many people with fullness under their chin feel that it makes them look heavier or older than they really are. Even patients who eat well and exercise regularly can experience fullness in the chin and neck due to genetics.  Although surgery can also be used to treat this area, Kybella can be done with no downtime in the office.


Since every patient’s anatomy is different, Dr. Sweat and his staff will work with you to create a treatment plan that is best to meet your aesthetic goals. The recommended treatment plan ranges from 1-3 treatments, performed 4-6 weeks apart. After the treatments, your body needs time to let the injection go to work to break down and absorb the fat cells. Results will continue to improve over the following weeks.  While there is no downtime associated with the procedure and the injections are relatively painless, within about 5-10 minutes of the injection, most patients will experience a dull achy pain similar to a toothache which will last an hour or two.  Swelling is often significant, which can make the area look worse before it gets better, so it is important to plan the treatment around important events or occasions.  The swelling will usually last for 5-7 days before returning to the pre-treatment look with slow improvement over the following weeks.  While the swelling and initial discomfort can be troubling, it is important to avoid medications that can counter the swelling response, as this is an important factor in how the product works.  Lumpiness and numbness to the treated area will slowly resolve as the fat is absorbed.
