A powder liner to structure, intensify, and thicken brows in a natural or more sophisticated way. The Brow Thickener fills out the thinnest, sparsest brows and instantly accentuates eyes thanks to its included foam applicator and its ultra-sheer powder formula that blends with your natural hair. The applicator can be used for a thin line to draw subtle brows or for a thicker line to fill out brows and provide volume.
