If you discard someone who doesn't look good without makeup, you're pretty shallow. Makeup is made to make girls (or guys) feel good about themselves, not for other people to like them. They aren't advertising anything, them looking good may be something to catch your eye with, but you're not supposed to fall in love with their face. Sorry for rant, don't usually do that. Just wanted to set these other commenters straight.
I read somewhere (from tumblr I think) a good response to this bullshit statement I never want to see or hear anymore: I'm not a product and I'm not trying to sell myself to you.
Well, we can't do it right now can we? We get labeled ugly and lazy without any make up, and it's ''false advertising'' if you wear too much of it. If you're not interested in women who wear make-up, you shouldn't hold them to your own impossible standards.
If we put makeup on it's for us, not for your guys :)
