Skin-discoloration Question?

OK so I have some acne scars and a little bit of skin discoloration. Do you think I should wear a tinted moisturizer and concealer or wait until I'm older b/c I'm only 12. I don't want a full blown flawless face with foundation. Or should I use something else to get an evener skin tone? I'm only in middle school so my Mom doesn't like me wearing a bunch of makeup.
