When a primer can do more than just create a smooth canvas on the skin, that's well and nice. But when it's so good it practically replaces your foundation and gives you a dewy finish, that's when it moves into must-have territory. Laura Mercier's Foundation Primer in Radiance ($30) achieves the ultimate balance. It subtly diffuses imperfections and brightens, all while leaving a level base for which makeup to lay.
Because it's thick in texture, a little goes a long way. That means not only will your foundation (if you even need it) last longer, but the primer itself will, too. Don't let its radiance claims conjure up images of glittery bits or excess shine, however. This primer's pearl tint lends a sheer, healthy-looking glow to the skin. And that's exactly why it's been described as "candlelight in a tube."
