I love this primer/setting spray! I find that it makes the most impact when used as a setting spray rather than a primer. After my makeup application, I use 3-4 sprays and my foundation and eye makeup stays put all day. I notice the biggest difference around my eyes and with my eye makeup after using the spray. I have hooded eyes and often find my eyeshadow to crease over the day. When I use this spray before and after makeup application the eyeshadow stays without creasing until I take it off at night!
