Using too much makeup. “I see more and more women wearing more and more makeup. Though I’m a huge supporter of wanting to look the way you want to look, I’m concerned that a number of women are simply following an Instagram trend. To me, that much makeup doesn’t even look good in pictures with professional lighting, let alone in full daylight or under fluorescent office lights.
OD’ing on brow pencil. “One trend I’ve been seeing that is bad is what I call the stencil brow. It has hard, square edges and an unbelievable arch. The brows are a vast mountain of little hairs. The best way to draw them on or fill them in is to use a lighter color than your hair and use featherlight strokes in the direction your hairs naturally grow. And it doesn’t need to be the same opacity everywhere—usually the brows are more transparent on the inner edges.” —Quinn Murphy, who works with Gigi Hadid, Lily Aldridge.
Making a mess of mascara. “I constantly see women who apply so much mascara but then don’t clean up the eye area properly. You’re then left with mascara smudged all over the lid. After applying mascara, I like to wait for it to dry before taking a dry Q-Tip to wipe away excess product that may have transferred onto the eyelid and underneath the eye. It only takes a few seconds, and it makes such a difference.” —Carissa Ferreri, who works with Gina Rodriguez.
