Concerns about chin lipo redo and leftover skin. Will there be pulling and wrinkling from a new incision? (photo)

Based on your photos- you have loose skin and muscle- that should be treated with cheek/neck lift. In my opinion- this is the only option that will produce the best result 

Good day, thanks for your question and provided information with pictures as well.. You need to consider to do a neck lift, you will have even better results from the procedure. Redoing the neck lift is your best option. Good luck with your procedure! 

You seem to have loose skin and loose platysma muscle bands. More liposuction will likely make it worse. The only way to fix the muscle bands is to redo the surgery (or Botox may give a short fix). The Z type incision may help but will leave a scar.
