Please carefully evaluate all pre- and post-photos of liposuction patients, whether using Cool Lipo or any other technique. Be realistic about your own skin and its elasticity because this is the most important determinant of the result you will get other than the skills of your surgeon.
I am particularly unimpressed by the photos of necks and abdomens where there is clearly too much skin laxity to get a nice result. These patients would have a much better result by a properly done surgical procedure such as a cheek and neck lift or a tummy tuck.
Be sure your MD can do all types of procedures so you can get the one which is right for you, not just the only one they know how to perform!
