What procedures would yield best results for me? (Photo)

There are a number of options for neck tightening, many of which you mentioned, such as kybella, coolsculpting, body tite, and some others, but the tried and true best way to do it is via liposuction. This will remove the majority of the excess fat and get your neck as tight as possible with given one’s anatomy.

Hope this helps!
