3 years and still have it.
Don't think it will go back to the way it was. Makes me look a little pg. I didn't have a c/s but did get lots of tummy stretch marks and that is what mine is from. I am hoping my other skin around my midriff will tighten as I lose more weight and will help a bit (I am a healthy weight but a large tummy size for my weight)
Sorry I couldn't give better news.
