Achieve Fuller, Thicker Brows With These Expert-Approved Buys

"This is the tiniest little marker and allows you to fill in brows hair by hair. It's amazing for creating natural, full-looking brows. I usually like to apply a brow pencil first to enhance/create the shape of the brow, then go in with this. They come in a good range of colors so you can use more than one color for extra depth." — Michelle Coursey
