On it's own, it can stand alone as a foundation, as it is made to be worn alone. That said, if you prefer a fuller coverage, this alone won't give you that. I've worn it over just primer and concealer and it's going to give you a light, natural coverage. When worn over foundation, however, it gives just a little bit more coverage but what I like is it mimics skin, so it's never cakey or dry. It has a nice satin finish to it.
