I received this as a sample in my Birchbox and ended up buying it. I didn't realize what a difference using a primer makes! MAKE really kept my skin oil free throughout the day, and it helped my makeup stay put. I ran out a few months ago and would love to buy it again, but it's been out of stock! I ended up switching to Pur Minerals primer (also Birchbox) and love it almost more-it's also paraben-free if you like that sort of thing, which I do. I would, however, buy MAKE primer again.
