Question About Lipo to Tighten the Jowls and Neck After a Facelift

I recently had a facelift and everything is coming back. I am really concerned with my jowls and my skin from my neck and that's the reason I had this done and I used a great surgeon. I was told that having lipo to tighten my jowls and my neck would be the best solution. My question is would that only be a band aid for a short time and then come back again and was also told that I can't have anything done for 6 months from the surgery date. I'm just trying to understand all of this.
