Makeup can sometimes feel like a girl’s worst enemy — which is why former model Stacey Schieffelin created “Your Best Friend” cosmetics. Her goal is to help each girl get the tricks and tools to make makeup shopping and application a breeze, starting with her easy-to-use line of high-tech, good-for-you formulas. Combining fun and sexy packaging with fab colors and textures, she has something every girl will fall in love with. Her eyebrow gel is foolproof, caffeinated eye shadow is a pick-me-up gem and light-refracting lip glosses are a must-have. Shop YBF cosmetics like this lipstick, $23 with a discount, by clicking here.
