How long does Kybella treatment last?

Kybella Treatment

Kybella is an injectable product that can be used to help your body to rid itself of fat cells that form under the chin (submental fat). Typically patients need 3-4 rounds of injections, each one month apart. However I recommend getting a in person consultation with a board-certified dermatologist.

Longevity of Kybella

Kybella is a permanent solution for treatment of submental (under the chin) fat reduction. Most patients require 2-3 treatments. Treatments are spaced every 4-6 weeks apart. Some side effects include swelling, tingling and numbness. Best of Luck!

Kybella's Effects Are Permanent

As with all fat-elimination techniques, the results of Kybella are permanent. In other words, once the fat cells have been destroyed, they are gone for good and cannot return. However, that does not mean you will not gain weight. If you develop poor exercise and eating habits and once more put on the pounds, you will probably see your double chin return. That doesn't mean that the Kybella hasn't worked; it means that the remaining fat cells are now taking up the extra fat that your body isn't burning as fuel.

Kybella works and the fat loss is permanent, but you must also work to maintain your weight in order to maintain the results. Please consult a board-certified dermatologist to find out how to eliminate your double chin for good with Kybella.

How Long does Kybella Last?

In the patient study, the results from Kybella persisted at the 4 year mark, and are considered permanent.  Once the fat cells have been destroyed, they do not come back.  Most patients will desire 2-4 treatments however to reach their goals.  In the studies, patients did up to 6 treatments.  As always, it is best to consult with a board certified plastic or facial plastic surgeon to discuss your goals and decide if you are a good candidate.

Thank you for your question. Kybella is a short in-office procedure with a procedural time that depends on the severity of submental fat. I suggest that you move forward and consult with a board certified facial plastic surgeon. The in-person examination will allow your surgeon to provide you this answer. Please post pictures.

Kybella long term results

Thank you for your question. Kybella works to destroy fat cells. Once those fat cells have been destroyed they are not able to come back. So the results should be permanent.  If you are interested in more information about this treatment I would contact your local board-certified plastic surgery.

Best wishes!

Kybella Results

Thank you for your question. Kybella is deoxycholic acid, a naturally occurring molecule in the body that aids in the breakdown and absorption of dietary fat. That being said the fat is destroyed and cannot come back. Results are permanent. Several treatments are needed to have the best results. 

Wish you all the best,

Kybella duration of results

Hi Jennifer,

Thank you for this excellent question. Kybella (deoxycholic acid) is a bile acid naturally produced by the body that is FDA approved for permanent destruction of submental (under the chin) fat. This is a truly innovative and revolutionary product with excellent and permanent results. Most people require a series of 2-4 treatments for desired results. I would highly recommend you go to a board certified dermatologist or plastic surgeon in your area to see if you are a good candidate for this treatment and to better understand potential side effects and downtime.
