Thank you for your question.If you are looking soley for a non-surgical solution, I am finding that the combination of Kybella or Coolsculpting Mini to reduce the sub mental fullness and an energy device to tighten the skin are among the best non-surgical combinations to help your neck concerns.Kybella is an injection procedure that dissolves the fat an may require between 2-4 treatments spaced 4-6 weeks apart. There is some swelling and bruising potential, with the greatest amount with the first treatment.The Coolsculpting mini procedure cools the fatty tissue under the submental area and also reduces the fatty tissue under the chin.As far as energy devices, I would recommend Ulthera if you are looking for something with no downtime, or Profound if you could tolerate some downtime. Ulthera is an ultrasound based energy that heats the underlying tissue and stimulates collagen in response. Profound is a radio frequency microneedling device that allows for the creation of Elastin, collagen and hyaluronic acid and hence restores some of the lost elasticity in the neck. It has more visible downtime with the possibility of some swelling and bruising that diminishes in about a weeks time.Surgical options are also very rewarding and include liposuction or neck lift. I would recommend visiting with a board certified plastic surgeon in your area to help you discuss your options in more detail.
