Meet Brow Flick, the latest makeup must-have from Glossier.

It’s a brand new brush-tip detailing pen that fills in brows with gentle, featherlight strokes for fuller, natural-looking brows. You can use it to define the arch and add depth to sparse areas. On clean brows, simply hold the pen at a downwards angle, start where your brows are more sparse, and etch lightly for added dimension or definition. Brow Flick comes in three sheer, smudge-proof shades — blonde, brown, and black. Follow up with Boy Brow to groom and hold hairs in place.

Brow Flick is available now at glossier.com for $22. To get the full Glossier brow, shop the Brow Flick + Boy Brow duo for $35.
