Oh yeah i had that happen. I used water proof makup like the skin colored creams and stuff. But thats not a garenteed cover. Best thing is to talk to your parents. Or if your scared like i was, try a bandaid on the site (if its liike a small patch) or makeup, or tattoos that last for a couple days. That can cover some. But get the black or red tattoos. like a big rose or something.
