Most primers succeed at smoothing out skin at a basic level, a few stand above the rest. If you have oily- or acne-prone skin, you might want to give Murad's Skin Perfecting Primer Acne and Shine Control ($35) a try. Formulated with salicylic acid to help keep pores clear, this matte-finish multitasker helps reduce and prevent breakouts. (Although it's not a substitute for your regular skin care regimen.) And because it's universal in color, it will match your skin tone to a T; you can even get away with wearing it with very little concealer or foundation on top. Oh, and if you're someone who gets oil slicks so major you've considered alerting the EPA, you'll love the way this primer helps put a stop to excess shine.
