Define and maintain your brows in just one step: L'Oréal Paris' transparent Volumizing Brow Mascara Serum allows for naturally defined eyebrows that look more defined and beautiful with each application. The feather-light, long-lasting gel formula with valuable ingredients intensely nourishes the brows, is water- and smudge-proof, does not flake, and does not clump. The precision brush with fine, short bristles creates a professional result and enables effortless application. With just one stroke of the brush, the eyebrows are cared for, defined, and set in place.
