I had my nose pierced when I was a sophomore in high school. I loved it until a nasty keloid formed and had to take it out. Here I am, a freshman in college. It's been three years since I have taken out the piercing, and I still have a gray scar due to the problems I had with it. I read online that the silver nose ring I had in it could be why I have a gray scar. Would it be absolutely stupid to repierce it again to try to get the gray out? Or should I just never get my nose pierced again and use Mederma or some sort of scar removal to help it?
