After your 20-minute session with our team, the results will present themselves over the next several months. Each session will be around the same time and treatments will be discussed with our professionals to schedule accordingly. Since the injections kill fat cells, the results are permanent. Fat cells die and are no longer able to store fat. Kybella reduces the number of fat cells under the chin. If one were to gain weight after the original treatment, new fat cells can begin to grow which could lead to minimal regrowth.
