2 c-sections and a belly button piercing scar: do I need a tummy tuck to fix it? (photos)

Thank you for your question.
Without evaluation and proper photos, it is difficult to say. However, the excess skin may require a tummy tuck to improve. I recommend meeting with a board certified plastic surgeon for proper evaluation and to discuss your options.

Yes!
A tummy tuck will remove most of your loose skin and piercing and leave you with a very flat and beautiful abdomen.
