No flakes or runs
I love this mascara because it doesn't flake onto my cheeks or run into my under eye area like other ones do.

It smells bad, like it's gone off. I didn't like the applicator, and I wouldn't buy it again... 3/10

Great Mascara
I stopped wearing eyelash extensions not too long ago because they were falling out to quickly. This mascara has made it so I don't miss my false lashes anymore.

This is literally the best mascara I've ever purchased. I'm not sure if it's the brush or the product. You know when your mascara dries out and you can't apply more, or else it will clump, YOU CAN with MAC highly recommend

Great mascara
Great mascara. Lengthens and thickens the lashes, doesn't smudge even after many hours. I got to sleep with the mascara on and in the morning it's still beautiful, just needs a little cleaning under the eye, and it looks great.

Would be good if it wasn't used…
I thought Ulta wasn't supposed to put returned/used mascaras back in the shelf? Either someone opened it in the store and used it, or someone returned it and it accidentally got put back on the shelf. But as soon as I pulled the stick out of the tube, there were two small black eyelashes stuck to it. You can clearly tell it had been used. It wasn't part of the brush bc the bristles are silicone like. I'm going to take back and exchange for a new one, but otherwise it looks like it works good.

Looks good but flakes off
I love how it applies on and the brush applies the mascara flawlessly but the product after it dries flakes off and ends up every where on my face and eyes which when you wear contacts irritates the heck out of them.

Love the color!
I'm a fan of brown, not black, mascara. I also use eyedrops, the store rep guided me to this mascara. I love it - the right color and it lasts.

Best Mascara!
This mascara did not disappoint. My lashes looked full and there was no clumping or flaking. It's a bit pricey for the amount but I would buy again because I haven't found any other product that provides the same quality.

Always works for me how I like it to.
Smooth, bold color, and very nice to use.
