Mattify! ULTRA

I have extremely oily skin.  If I wash my face and don't put anything on it, I am shiny within half an hour, and slick within an hour.  I was searching for a primer that would help control my oil, and came across a review for Mattify! on EDS, and after reading the reviews on MUA, I ordered the smaller size, opting for the ULTRA formulation instead of the regular or sensitive, because I figured I needed as much help as I could get.
