Natural looking makeup?

First of all, you have to be confident in yourself! If you are confident in yourself, others will think you are confident, and many people find that very appealing! If your birth mark bothers you that bad, consider getting it removed. If you don't want to or can't try to cover it up with some concealer and foundation, or even a nice shade of eyeshadow! Because makeup isn't allowed, just use a little concealer on dark circles and blemishes, light foundation, light mascara, and eyeliner or eyeshadow. Just make sure not to overdo it, otherwise it will not appear natural. If you need help, ask your mom or sister or check out some videos on youtube! The makeup I use is: Covergirl concealer and foundation, Clinique eyeshadows, Great Lash mascara, Maybelline eyeliner, and chapstick or light lipgloss. Hope this helps!
