thinking about laser lipo

Options
Ive recently lost about 50lbs. I have about 50 more to loose and I notice that my skin is starting to sagg a bit. Ive been working out but thats not doing the trick for me. A friend of mine told me about laser liposuction and how it helps tighten up the skin. Has any body on here ever had the procedure. Please give me feedback, I want to know your experiences...
