Review (5/5): Awesome primer
This is the best primer I've ever used. I have extremely oily skin; I'm usually super oily within 2 hours of putting on my makeup, but with this, I can stay oil free for about 5 hours and then I'm only moderately oily after that. If I use this and my Becca matte primer (which I have mixed feelings about), I can stay oil free for a full day!
