21 Product Picks From Hollywood’s Greenest Celeb Makeup Artist

Until recently, many natural cosmetics simply couldn’t compete with conventional lines. Products claiming to be free of preservatives (like parabens) often also lacked the key characteristics to make them actually work, like the formulations necessary to deliver bold pigments to lips and eyes, lasting coverage over imperfections, and an enviable glow to cheekbones — many of the exact reasons why many people wear makeup.
Fortunately, those who strive to add eco-friendly and more-natural options to their makeup bags now have reason to rejoice, because the world of natural beauty has made major advances in the past few years. Need proof? Enter celebrity makeup artist Katey Denno. Nicknamed the "green makeup artist," she swears by the natural, eco-friendly products she uses on clients like Amanda Seyfried, Amber Heard, Mindy Kaling, and January Jones. And, if you've seen her girls on the red carpet, you know she's not sacrificing efficacy for eco. 
Clean beauty products are now just as good as their conventional counterparts. So, how do you know which to choose? In the spirit of Earth Day, we asked Denno to take a break from her celeb clients and rad eco-focused blog to teach us how to shop green, right here in L.A.
