Body Wraps?

I've been seriously noticing some skin loose-ness issues lately. My upper arms (which have always had "bat wings" since I can remember losing weight 4yrs ago) and a bit on my tummy (like right above belly button) and definitely lots on my thighs.. I've always hated my thighs because they've been big since I was a little kid (even before I was technically "overewight") and now there's loose skin around the top and especially above my knees.. it kinda grosses me out and I dont like the way it looks. I'm meeting with my doctor on the 17th and he does plastic surgery to correct these kind of things (when exercise on its own doesnt work, like it doesnt for me!), but I've also been reading about body wraps lately.

Has anyone tried them? Did they help? Do they really help tighten skin/lose some inches? Would you recommend them?
