    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.

Great for Volume

Great at adding volume to lashes without caking them in product! Next to no transfer or flaking.

Not worth the price

After 1 or 2 uses the tube and brush go clumpy and it's garbage. I've tried 2 tubes and the same thing both times. Very cheap quality. It also flakes and falls within a few hours of application

The smudging ruins it

I love the way it goes on -- so smooth and never clumpy. However, within an hour or two of applying it, I have extremely noticeable dark smudge crescents below both eyes. Should I close my eyes for even 5 minutes, it looks like I was punched. I've never experienced mascara that smudges so easily and quickly from just like...blinking. I don't rub my eyes; this happens regardless of the weather (humid, not, raining, not).

I have bought over and over.

This is one of my favorite mascaras! I have tried so many and I got this in a sample pack a couple of years ago. It lengthens my eye lashes and they actually stay up! Easy to work with and the brush is great! The only negative thing is that it does not come in waterproof. So if you sweat or your lashes get wet, it will melt off and smudge. So I try to use a waterproof mascara over it if I know I will be sweating. I enjoy it and have bought it over and over.

Not great

Very liquid formula, falls below the eyes throughout the day. Not as good as the original this update was meant to replace. Doesn’t add volume. Brush is the only good part.

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