Amp up your mascara with Photo Finish Lash Primer. Perfected on photo shoots to condition and lift lashes to new heights, it’s formulated to boost lashes and make mascara last longer—and it never flakes or smudges. Featuring Smashbox’s dual-sided Two-Timer brush, it has an ultra-thin comb for clean, clump-free separation and molded bristles that enrobe each lash. Just layer for an even bolder lash look.
