If you use HD creams, this is the perfect primer. It creates an amazingly poreless, shine free, no-makeup look. I have never had an issue with white cast and the small size of the jar is deceptive. If you use sparingly (as directed) white cast shouldn't be an issue for you either and the jar should last a looooong time.
I could seriously go on forever about how amazing this primer is but I'll reign it in a bit and just reiterate that this stuff is freaking fabulous.
