By "turkey neck" patients usually mean their neck has laxity and is droopy. This can be corrected surgically if severe, or via #Ultherapy if less severe, especially in those wanting to avoid the potential side effects and high cost of surgery. If you also or rather have excess fat under the chin, you would want to have one or more treatments with #Kybella. There is some intending of the skin with Kybella in addition to reducing the fat under the chin, so if you have fat and mild to moderate laxity, this would probably be the way for you to go go. Then, if you still see any laxity after Kybella, you can still have Ultherapy. All the best, Dr. Clark
