How long does the results of Kybella last?

Kybella induces fat cell death, and new fat cells don't tend to grow in the place of the treated cells. Although the residual living fat cells can each absorb more fat, this clinically does not seem to happen unless someone were to gain excessive weight.  Kybella hasn't been on the market as long as we have been doing neck liposuction, but the procedures can be thought of as having the same long term duration of results. In more than two decades of  performing neck liposuction in my NYC practice I am not aware of my patients having noted their fat to return in the neck.The information provided in Dr. Shelton's answer is for educational purposes only and is not intended to constitute medical advice.  The information provided should not be relied upon as a substitute for consultations with a qualified health professional who may be familiar with your individual medical needs. 

Hello,
Thank you for your question. Kybella permanently reduces fat. You may need more than one treatment to attain the desired result, however once the fat is treated, it is permanently gone. Good luck!

The medication permanently lysis the fat cells which live under your skin and above the platysma muscle. As long as you maintain your weight, then the results are permanent. This is the only FDA approved injectable for fat removal under the chin and it is safe.Best wishes, Dr. ALDO
