want thick caked-on concealer packed under your eyes; it can make what you’re trying to hide look worse. Try a sheer liquid formula packed with light-reflecting particles to brighten the skin. Using these products on pimples, however, is a no-no. Instead, cover them up with a green-based concealer to nix any redness, then, lightly apply a more natural shade over the top. Just don’t layer it on too thick.
