EMFACE VS SKINTITE

So I'm looking to have a noj surgical procedure on my jowls. No needles, no abrasions . Has anyone tried EMFACE or Skintite? What are the major pros/cons and differences? I'm 3 weeks from 51 and lower half of face had dropped literally overnight plus some skin darkening. It really bothers me and kills my self esteem. Suggestions? Help.
