Kybella, SculpSure and CoolSculpting are the non-surgical procedures that I use to address a double chin. The right one for you is really going to depend on your anatomy and tolerance for downtime. Kybella was actually designed specifically to address submental fat under the chin and can be the ideal option for localized fat in the area. But if you have a higher degree of excess fat, SculpSure or CoolSculpting may be a better option. My best advice is that you schedule a consultation with a Board-Certified Plastic Surgeon in your area to be assessed in person.
