1. No Arch
The fix: You can create the illusion of one with this simple trick: Brush the brows up and angle out with a spoolie brush, like Trish McEvoy Brow Groomer ($14; Bloomingdales.com
). Then apply Anastasia Matte Highlighter ($21; Anastasia.net
) under the outer half of your brow. Never overtweeze the tail ends—without them, you can't create an arch.
