Thank you for your question aresbany. Kybella is the first and thus-far only FDA-approved non-surgical injectable treatment for the double chin. Kybella can be administered by any physician which has appropriate training. A series of 2-4 treatments is recommended, sometimes up to 6 treatments. I treat my patients every 3 months. Results are seen slowly over time. Patience is important. We usually use 2 vials per treatment. Please consult with a doctor for specific recommendations. Good luck!
