Can you wear makeup before you get your nose pierced. Like have foundation on while they are piercing it or do you have to be wearing no makeup?

No,I don't think that is too safe.The chemicals from your foundation can get into the hole,where they pierced the nose!

To be safe,don't wear it! If your piercer is legit they'll clean the area before they pierce it. Just to make things easier, don't put makeup on your nose.
