I think I have tried every single primer on the market (okay, a bit of an exaggeration, but I've definitely tried a lot) and I have found that L'Oreal's Studio Secrets Magic Perfecting Base is actually one of the best. Who knew a drugstore primer could knock out some of my top-tiered ones?! This stuff is inexpensive (base one), you can always find a coupon for it (base two), really smooths out the skin beautifully (base three) and has incredible staying power (homerun). I can't even begin to tell you how much longer my foundation has lasted because of this little glass pot of goodness and how smooth my face feels after using it. I love the texture (so incredibly silky) and there's no smell (and I've had no irritation with my sensitive skin whatsoever). This is a definite must-have and at drugstore prices, it's a definite no-brainer as far as I'm concerned.
