24/7 Glide-On Lip Pencil, Get primed and ready for action. This long-lasting, waterproof liner glides on smoothly to prime AND define-for long-lasting lip color and clean lines. Smooch. Pout. Smack. Nibble. Lick. 24/7 stays put through everything (yes, EVERYTHING) you do. When you use this liner to fill in your lips completely, it primes them for lipstick or gloss, grabbing on to color to help it last. Part of the 24/7 family, Urban Decay's long-lasting, waterproof formula glides on smoothly, stays creamy and defines your lips with gorgeous color. And unlike a lot of waterproof pencils, 24/7 never feels dry or cakey. Moisturizing vitamin E, jojoba oil and cottonseed oil nourish your lips every time you reapply. And shade-matched barrels make it easy to find the exact color you need (no matter how crammed your bag is). Even women who don't usually wear lip liner love Ozone, Urban Decay's best-selling clear shade. Like all their other shades, it holds color in place and prevents feathering--yet it's totally invisible on your lips. Tip: For ultra long wear, fill in your lips completely with 24/7 Glide-On Lip Pencil in Ozone (UD's clear shade) to prime lips and prevent feathering. Then, to intensify color and provide even longer wear, apply 24/7 Glide-On Lip Pencil in a shade that matches your favorite lip color. Follow with Revolution Lipstick (or your favorite UD lip product).
