What procedure would help with turkey neck and double chin? (Photo)

An alternative would be a necklift to eliminate fat in the area and tighten the underlying muscle.  Kybella alone would not solve the problem.  Fat elimination with tightening is needed and I would advise muscle tighening rather than skin or dermal tightening alone.

Get rid of that turkey neck and jowls with a little lower face/neck lift under local and see an amazing result. It is very easy to undergo and look so natural.

In all likelihood, the most benefit for you would be a necklift or minilift type of procedure to improve your neck and jaw line. It appears that you have some fat with some excess skin and perhaps some muscle banding. Fillers or kybella alone would not correct the issue and a lifting procedure for that area that would address the skin, muscle and fatty tissue would be your best option. Good luck in your area.
