Bare minerals matte powder. The matte covers much better than the original. If I need a liquid under for special occasions (ill be sweating alot, etc) I use a Benefit primer. I love Ulta and have found the girls there very helpful without being too pushy to sell.
I love Stila illuminating foundation. I have dry skin so I like the glow it gives. It is a lighter coverage but hides flaws well and makes you look dewy.
