One of the biggest summer make-up challenges we face is watching our eyeshadow melt right off our eyelid. We leave the house with the perfect bronze-y gold smoky eye, and by the time we get where we're going, there's a pound of make-up settled in the crease and instead of looking light and shimmery, our eyelids just look oily.

Fortunately, there are products to combat this exact problem, and the one that we've heard the most buzz about is Urban Decay's Eyeshadow Primer (seriously -- check out the reviews!). It delivers "eyeshadow that lasts, color that stays vibrant all day, and absolutely no creasing." You dab a bit of the nude-colored cream on your lid, add your liner and shadow, and it all stays put until you remove it -- even in the heat of summer!
