I recently bought this foundation because of all the great things I've heard about it. I bought it with MY OWN MONEY & I'm actually thinking about returning it instead of trying it at all.... Part of the reason I bought it was because of the whole weightless, perfecting, & waterproof claims in the title. I have oily to normal skin and thought this was going to be a great matte foundation.
