Brow Pop
Fill. Define. Shape it.
Kosas’ Brow Pop Defining Pencil is a clean, dual-action micro-triangle brow pencil designed for effortless precision and natural-looking definition. Featuring a thicker side to quickly fill in sparse areas and a finer tip for shape and detail, Brow Pop delivers long-lasting color that stays put—no smudging, no fading.
Infused with conditioning actives like castor oil to encourage fuller-looking brows over time and Provitamin B5 to revive and strengthen, this pencil doesn’t just define—it treats. Available in natural, buildable shades to match and flatter every brow.
