    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.

Nice one!

It is the perfect consistency. Not too thick or too wet. It is a rich black color. The brush lifts and separates the lashes. It also builds easily without clumping. I would recommend curling your lashes with a lash curler before applying. I typically apply two- three coats. It stays put without smearing or crumbling, until I am ready to was it off. It is a little more difficult to wash off, so I would recommend a makeup remover or a double wash with your favorite face wash. I get compliments on my lashes all of the time while wearing this mascara. I have had a few people say they thought I was wearing false lashes. It really is that great!

This mascara was another winner. It made my lashes look long and fluffy. It also lasts a long time and does not smear. A high quality mascara that doesn't break the bank! I definitely recommend this amazing mascara

Will buy again

I love this product. It's the best mascara I have ever used as it makes my lashes look more defined. Once, a lady even asked me if I was wearing false lashes.

Mascara from the gods

My holy grail mascara - I tried it two years ago and will never stray. The application is beautiful. I love the thicker brush, and it’s buildable so if you like the wispy look, one application is enough. Thicker style, another layer and you’re set. It lasts forever, and stays all day without flaking. The only thing I’d mention is that if you’re a person who tears up or suffers with watery eyes, this may not be the best because it’s not tear proof at all. So it’s a great mascara for a great day - don’t go ending your relationship while wearing this.

Would buy again … but

Love the mascara its self. It’s very light weight and doesn’t smudge. My only complaint is the packaging. It feels cheap and there is still marks on it from when I took the sticker off.

BEST MASCARA EVER

I’ve used this product for over a year now and I love it! I have short Asian lashes and it really defines and lengthens them. It doesn’t clump or smear when I wear it all day. It also does an amazing job at holding the curl all day. If can’t recommend this product enough.

Great mascara at a bargain price

Love the brush and smoothness of the formula. It does tend to flake by the end of the day. My daughter uses the waterproof formula and loves it!

Wanted to love it

I liked the mascara but unfortunately it made my eyes itch really bad. This has never happened with any other brand.
