We love to wear daring bright lip colors, but we can't seem to make them last all day. We layered on our newest crimson red to deepen the shade and at first blush were most impressed with the results. But as the day wore on our color started to smudge and then it started to feather. It looked as if pigment had seeped into all of the cracks of our lips and then found a nice downstream route onto the rest of our face. The lesson? Invest in lip primer if you are serious about lipcolor. Here are our favorites. Philosphy Big Mouth Primer, Urban Decay Cosmetics Lip Primer Potion.
