I have used a lot of eyeshadow primers but this one beats them all hands down. They also recently changed the packaging from a wand to tube, which makes application easier and more sanitary. You can apply this primer and then wait for it to dry, or just put your shadow right over it. It makes your shadow last all day and concentrates the pigments. It is also great with creme shadow. It gave my Make Up For Ever's Aqua Cream shadow a more uniform, smoother look. Urban Decay Eyeshadow Primer is available in four colors, original (nude), Sin (Shimmering Champagne), Greed (Gold) and Eden (Matte Tawny). Eden is great if you have "stained" eyelids, it will cover and prime at the same time. Available at Sephora and UrbanDecay.com, $19.
