Since I discovered the Smashbox primers, my beauty routine is changed forever. As a MAC fan, I was hesitant to use a different product, but now that I have been using this primer for 2 months, I will never use anything else. The Smashbox Photo Finish Hydrating Primer delivers a fresh and long lasting hydration to the skin, while smoothing out lines and extending your make up wear. The formula is light and non greasy - the perfect primer.
