I find girls to be better looking without make-up. Although I guess it could be just my preference. But make-up is also more like a fashion thing for like formal parties and stuff. It does make you seem a little more elegant, unless you put it on wrong... then you look trampy
If a young girl wears make-up though, they look older... Like those preteen beauty pageant girls... hold on let me find some pics..
I don't know who she is (I just googled real quick), but she looks old for her age because of make-up:
