I have used this concealer for the past few days, and I really love the way that it brightens up under my eyes. I am extremely fair skinned (N21 tends to be too dark for me), and this actually brightened up my face for me. I have tried setting it with 4 different setting powders, but it always ends up breaking down by the 5-6 hour mark. Overall, I am very pleased with this product and would purchase it again.
