I treat this everyday in my practice. You may be a surgical candidate but you do not need surgery for improvement. Properly performed liposuction with energy based devices and physical fat removal will do fantastic to remove the fat, lift the skin, and contour the jawline. I pretreat everyone with Botox 1-2 weeks before surgery to relax the neck muscles, allowing for better retraction of the skin after surgery. Then after treatment we do skin tightening with Venus Legacy to improve the results and decrease the neck swelling. I suggest you only see an expert for treatment of this area as a meticulous surgeon is required to get great results and complications in this area can be devastating both medically and cosmetically. A new medication that is used to remove chin fat with injections called Kybella may also be an option, as it secondarily allows for skin tightening/lifting as well. A formal consultation is needed to determine what are the best options for you. Coolmini can work well for certain patients on the neck but often need more fat than skin, so if you have a "waddle" ensure this is fat and not just skin which would require lifting or ThermiRF as well. Best, Dr. Emer. Best, Dr. Emer.
The new CoolSculpting Cool-Mini applicator can be used to reduce fat of the double chin. Most turkey waddles, however, are the result of loose neck skin. This will not be treated by CoolSculpting. An alternative treatment may be more suitable for you. To best determine, you should see an experienced physician in your area for consultation. Your age is not an issue. Best of luck.
