Hi there, I am not an expert in this area, but I've done some research and, based on our findings, I think that a neck lift can be a really good option for people with sagging skin. There are a lot of different kinds of neck lifts, but the common theme is that they lift and tighten the skin to improve their appearance. Sometimes, this is done by removing excess skin and fat or tightening muscles, but in other cases, it is done by removing the extra skin or fat and then lifting the skin to its correct position. The recovery time will depend on the kind of procedure performed, but after the recovery period, I think that a neck lift can be a good option for many people, and I think that you should consult a board certified plastic surgeon who can evaluate your concerns and help you make the best decision for your needs.
