Key Features and Reviews This mascara is designed to create a false-lash effect without actually using falsies, offering intense definition and lift that holds all day. Formula: The superproof formula is resistant to water, sweat, tears, and oil, which helps prevent smudging, clumping, and flaking. It is also fragrance-free. Brush: It features an optimized hourglass-shaped brush designed to grip and extend every hard-to-reach lash, providing precise application. Volume & Length: It adds subtle, lightweight volume and definition to create a natural lash look. Some reviewers noted it provided more length than volume.
