    Big By Definition Waterproof

    Because every lash counts, SEPHORA COLLECTION is launching a waterproof version of its Big By Definition mascara for a fuller, water-resistant fringe.

    Results: Volume, Definition, Water resistance

    This mascara separates lashes one by one with its multidimensional brush

    The definition pumps up your lash volume. Waterproof Big By Definition is a mascara that separates lashes for instant definition from the different sized fibers in the brush.

    Each of the brush’s fibers catches lashes of every size, making it the perfect mascara for lower lashes and small lashes. Makeup results: every lash is revealed and the fringe is +151% longer and fuller(1); it also resists water thanks to the mascara’s waterproof formula.

    This buildable mascara creates volume and adds density for lashes that are up to 3.6x thicker(2)

    With its waterproof formula, Big By Definition isn’t just a lash-separating mascara. It goes further to give your eyes a very impactful look. Aim for definition in all circumstances with this ultra-resistant version of the cult Big By Definition mascara. With its buildable, long-wear formula, this SEPHORA COLLECTION mascara creates volume and adds density for lashes that are up to 3.6x thicker(2). This vegan waterproof mascara resists water, heat and humidity. It won’t run, smudge or flake.

    Made with plant-based waxes, this mascara’s light, stretchy texture envelopes each lash from root to tip, all while smoothing and conditioning to fully define the fringe, lash after lash.

    It gives you buildable results that get more intense after each stroke for an ultra-dark, clump-free look.

    This volumizing mascara’s lash-separating vegan(3) formula is enriched with plant-based proteins whose structure is similar to that of keratin. This long-wear mascara doesn’t run or flake. It holds all day long yet is easy to remove.

    (1) Measured scientifically on 24 false lashes after 10 brush strokes.

    Don't waste your money

    -I've worn this mascara a few times. It is not waterproof within a few hours I have black under my eyes which is very disappointing! it's useless. I've tried it on several occasions by the end of the afternoon I have black smudges. lesson learned.
