MAC Stack Waterproof Mascara - Ulta Beauty

I received this product for free from Topbox Marketing for testing and review purposes. I love it! MAC never disappoints and this mascara was exactly what I need it. No clumps, separates eyelashes well while giving volume. Makes them look really long. Highly recommend.

I'm really loving how this mascara lifts my eyelashes without them looking clumpy. The formula gives my lashes some volume, but keep some separated and wispy looking. This mascara contains argon oil and plant-based waxes which makes it 91% natural ingredients. There's no smudging and this formula is said to be clump proof. So far, I really love this product. The brush has a contour to it to lift the lashes but at the same time giving them volume. Overall, I love the results and can't wait to purchase again!

Love this mascara! Absolutely beautiful great quality! I really think this helps me achieve a great length and volume without it looking too clumpy or overdone! Lashes feel nourished and moisturized as well which I never see with most mascaras on the market! Would definitely recommend this product! So glad that I received this product for free from Topbox Marketing for testing and review purposes!

NOT even remotely waterproof. Returning.

[This review was collected as part of a promotion.] The MAC Chestnut Mascara is a game-changer for anyone who loves a softer, more natural lash look. Unlike traditional black mascara, the deep chestnut brown shade gives your lashes definition without being too harsh — perfect for daytime looks, no-makeup makeup days, or enhancing lighter hair colors. It's also a subtle way to make your eyes pop without overpowering your makeup. The packaging is classic MAC — sleek, black, and professional. The wand itself has a slightly tapered, fluffy brush that makes it easy to coat every lash from root to tip.

Unique brush, DENSE formula, PITCH BLACK coloring the deepest black pigmentation ive come across in mascara and it thickens your lashes something serious. You will feel it on, this is not a light breezy wispy product - it is meant to be seen. Use an oil based remover to get it all off

I got it as a sample and i love it. I went to the store to buy the full size 💗💗

Who needs fake eyelashes when there's M.A.C.Stack mascara. I have been using this mascara for several years now. I am very pleased with it. It thickens and lengthens my eyelashes very nicely! I love the tubing and the silver ball. on the top. It comes in a waterproof version that really stays on...forever. Just joking, but it's long lasting.

Make sure you wipe it off after each application but the clumps are extreme. Still wishing for Zoom Lash to come back. I try each one thinking it might be an alternative but nope! So far Extended Play is tried and true.

Holds up to its reputation. It doesn't clump and it helps with making my lashes look thicker since I naturally have short lashes.

Leaves lashes beautiful and separated.

I do not like this mascara. It clumps and for some reason MAC will not allow you to return this product.

I will always reorder this and keep buying. I live my mac stack and it is the best mascara I have used in quite some time.

[This review was collected as part of a promotion.] It is a good mascara.

My natural lashes have become thinner and more sparse as I've gotten older, so a mascara really has to be amazing in order to wow me these days. This one did that. My lashes looked both fuller and longer and the best part is that I did not experience any smudging or flaking throughout the day. The only thing I'm not super keen on is the brush. I like the spikes, I think they do a nice job at gripping and coating the lashes but what I don't like is the shape overall. It makes it difficult to get an even application; I like a brush to be equal size straight across. the tip of the wand is not well executed because so much mascara builds up there (which yes is normal), but the spikes are very haphazard in that spot that it's just messy even if you wipe off the excess & tends to clump my lashes together. I think next time I will try the MacStack Micro instead. Overall it's a great mascara.

I'm not sure how this has gotten awards or such great reviews. I almost wonder if theres something wrong with the wand I got. It applies so much mascara its insane. Goes on thick and clumpy and awful.

Truly stackable. If you like being able to layer on your mascara and control how natural or dramatic you want your look then this mascara is for you. No flakes and wears nicely all day.

I am a mascara junkie and I have tried all the high end brands. The micro mascara for shorter lashes is hands down the best mascara I have EVER used!!! It doesn't clump and layers on perfectly. No need for falsies with this. It is amazing and you won't regret trying it out!!!

I got this mascara with a eyeshadow palate I purchase and was very surprised how well it worked for me. I would purchase again.
