Re: A question about foundation
i think different people react differently so that is why you have to find something that works for you
it never turns dark for me either... on my sisters wedding i wore it around 7:30pm and we took pics until 5am and it looks perfect...never yellow...never dark
and i also use a primer but i use smashbox primer and using a primer is a must if u want your make up to last for more than 1 or 2 hours
that could be on reason? and the other important thing is to set your make-up in the end with loose power
all MUA recommend using loose powder as you end up using less product with better results and use compact powder only for touch-ups
