Immediately following the staple removal, your skin may be irritated from where the staples were. This is not how your c-section scar will look forever. You may see tiny holes were each end of the staple was in your skin. These usually fade very nicely. Sometimes you don't see them at all after a while or they fade to tiny dots lining your main c-section scar.
Your doctor will also give you instructions on how to care for your incision and discuss warning signs for your incision.
