Whether you make your living doing makeup or you're just makeup-obsessed, you know the right brushes can make all the difference. The UD Pro Smoky Crease Brush by Urban Decay is the ultimate combination of form and function—it helps define the crease or blend out shadow. Urban Decay's pro-quality, cruelty-free brushes are easy on the eyes and the environment. The brushed gunmetal handles are made from recycled aluminum, and the super-soft, synthetic hair (made from recycled plastic bottles) mimics real hair—from the feel to the pickup and laydown. Another plus: Synthetic brush hair doesn't hold on to gross bacteria the way porous animal hair can, so it's easier to clean and more hygienic.
