What shoppers are saying: "I never find foundation that matches my skin tone and feels this good. This one is a winner right out of the gate. Looks like I have nothing on and I have very uneven skin tone. It also covers well using very little product. My skin feels amazing." (via Sephora shopper vsquared)
