I'm so glad I bought this primer instead of the $100 one at Sephora. It does exactly what a primer should do: primes the skin's surface for easier makeup application. I applied the primer on top of my daily sunscreen -- I couldn't believe how smoothly it glided across my skin. Next I applied a tinted moisturizer and mineral powder and was thrilled that there was no icky product pilling. Yay! It lasted all day and gave my skin a little extra glow. I have normal/combo skin that gets easily dehydrated. The primer was neither to greasy/shiny or drying for my skin.
