I lost over 40 pounds in my 20's and my skin is only getting looser. I didn't want the pain or cost of a tummy tuck so I decided to try Exilis. I had five treatments over the course of 4 - 5 weeks. The procedure itself I would describe as being uncomfortable at times because of the heat of the laser, but nothing extreme. I'm not really sure how much of a difference I really see. I was told it may take a few more weeks to see final results.
