At 12 years old, make-up will only make you look older, and this can cause attention from unwanted people like perverts. I am not even joking. If you wear make-up and you look good, you’ll be hit on. And at 12 years old, do you really want to get such disgusting male attention? I don’t think so.
I am proud that you have decided to stay natural, because you shouldn’t let these girls at your school influence you in any way. If they all want to look like a clown, let them. They’ll regret it in the future, trust me. You have so many years of your teenage life to come and you’ll have plenty of time to experiment with make-up. Be who you are, not what others want you to be.
Good luck :)
