Offering continuous, buildable volume, MAC presents the Stack Mascara, a breakthrough formula that resists clumping, flaking and smudging, layer after layer. Create customisable definition, levelling up your look from soft and natural, to bold and dramatic.
The bespoke mega brush coats lashes from root to tip with 360-degree coverage, while proprietary Fibre Melt Technology helps to create a smudge-proof finish. With a weightless feel and up to 24-hour wear, the gravity-defying mascara creates the illusion of instant lift and length.
Press the brush into lashes close to roots and shimmy brush through from roots to tips. Keep stacking the weightless, clump-resistant formula for limitless volume and length potential.

Gamechanger!
Bought the full size mascara after having a sample and it is amazing! No clumpiness, no transfer, no fallout. Excellent product

Nice Mascara
Applies well but I prefer some of my other mascara brand and the brush is easier to use on them, this one is a little too thick.

Not for me
I’d heard such good things about this mascara from friends that I had to try it. It goes on great and looks good but starts to smudge after a couple of hours. I so wanted to like this but it just doesn’t have the staying power.

Great mascara!
I first used this when I got it in the look fantastic calendar and have been using it ever since. Really nice mascara, doesn’t stick lashes together and I love the fact you can build up to your preferred style of lash.

Awful product
This product is fantastic if you want to go for the panda eyes look. It will bleed from your lashes onto your skin and make it look like you’ve not slept in 2 weeks, and that’s only with one layer

Longer lashes
I love this product, no smudge or clumping. I have short and fine lashes so it's OK for the length but not if you want thicker looking lashes

Great lashes
I’ve tried many different mascaras but this has to be my favourite. No irritation for my sensitive eyes and great lash length every time.

Love this mascara. I’ve just repurchased after getting it in the Xmas calander. Stays all day and doesn’t smudge

Lengthening
Nice plastic brush, fans the lashes out and gives a lot of length
