    Because every lash counts, SEPHORA COLLECTION’s Big By Definition mascara multiplies lashes by revealing them one by one for a fuller lash fringe.

    A mascara that separates lashes one by one with its multidimensional brush.
    When volume comes from definition.

    BIG BY DEFINITION: the mascara that separates lashes for instant definition thanks to the different sized fibers in its brush. Each fiber catches every lash size, making it the ideal mascara for lower lashes and small lashes.
    Makeup result: every lash is revealed and the lash fringe is fanned out and +135% fuller (1)

    A mascara with buildable volume that densifies lashes for a result up to 3x thicker (2)
    Big By Definition isn’t just a lash-separating mascara. It goes further to give your eyes a high impact look.  With its buildable formula, this SEPHORA COLLECTION mascara adds volume for lashes that are up to 3x thicker (2).

    Formulated with vegetable-derived waxes, this mascara’s lightweight, stretchable texture envelops each lash from root to tip, smoothing and conditioning to fully define, lash after lash.
    The mascara has a buildable result that intensifies with each stroke for an ultra-black, clump-free look.
    This volumizing mascara’s lash-separating vegan formula (3) is enriched with plant-based proteins whose structure is similar to keratin.
    This long-lasting mascara won’t run or flake. It holds all day long yet is easy to remove.

    (1) Scientific test on 24 false eyelashes after 20 brush strokes.
    (2) Scientific test on 24 false eyelashes after 30 brush strokes.
    (3) Formulated with no ingredient from animal origin.

Doesn’t add a lot of volume. Positives are no clumping.

Horrible. It is heavy to apply and smudges so easily, lasts max 1-2 hours before it smudges.

it's okay

Was very thin, and didn't make my lashes look much better. It's very light, and doesn't feel like I have any mascara on. It's good if you layer another mascara on top, but not by itself.

Great!

This is a great mascara! It is a very “wet” mascara and I have very long eye lashes so I like to ease this on! A little goes a long way!

Smudgy

Looks amazing for about an hour, but I found it both smudged under my eyes AND was difficult to remove at the end of the day. I wanted it to work but after multiple attempts I gave up.
