This primer is the best primer that I have ever used. When put on, you can feel that your skin has become very slightly tacky, which helps your foundation stick. Your foundation doesn't slide all day, and your contour looks just as good after a day at a festival as it did when you put it on that morning. Hands down best primer. My only complaint is the price, but for a product this good, it's worth it. And it really enhances any foundation, from drug store to high end.
