Can my belly button be fixed? (photo)

I had a "tummy tuck" 4 years ago it was just skin removal my muscles were not tighten or stitched. A week post op I had my incision open and I had to go back in to close it. A week later my BB started closing I had a revision as well The skin around my BB is really thin, I can see the veins through that part of the skin, it looks like it has a lot of tiny stretch marks around it My dr said it happened because I was allergic to the stitches I want it fixed but I do not want to make the scar worse
