I had a surgery when i was born because of a collpased organ. The scar is now about 5 inches long. It causes a big depression and really bothers me. I think that when they did the surgery they removed the fat underneath the layer of skin and it is uneven. Can the scar be revised through grafting and laser? Also can fat be added or removed from the the full stomach to make it even? I would like when I lean or bend it doesn't cause this awkward bend in the skin. Are these alternatives safe?
