The key? "It's not about the shine — it's about the shock of color," Dubroff says. That's why she applied Obsessive Compulsive Cosmetics' Lip Tar in Queen ($14), a vibrant, satiny red-coral, over Nars Pur Matte Lipstick in Carthage ($25), a richly pigmented hot pink. This way, by layering two ultrabold colors, you'll get even more intense, long-lasting results. And that's what you call hot stuff, hot stuff.
