18 Classic Beauty Products Our Editors Will Buy Over and Over

"I have oily skin and very thin eyebrows, so the Anastasia Beverly Hills Dipbrow ($18) has been a lifesaver. It's the only thing that makes me look like I have more than three eyebrow hairs and doesn't melt off my face midday like other brow products I've tried. I always look like I have thick brows because of this awesome product." — Sarah Siegel, assistant editor, Beauty and Shop
