What shoppers are saying: "It only took one application for me to fall in love with this foundation. A week later and that still hasn't changed. I always have a problem with foundations separating on my skin and this doesn't happen at all with this foundation, even after having it on for 12 hours with no touch ups. Not to mention, the coverage is AMAZING!"(via Sephora shopper MariahW17)
