1)My eyes are sensitive to waterproof mascara. Does the "24 hour" mean waterproof? 2) what type of product should be used to remove it?
- Asked by Sally
- Official Answer By MACThanks so much for your question! While MAC's original MACStack Mascara is incredibly long-wearing, it is not waterproof like MAC's MACStack Waterproof Mascara. We recommend using MAC Gently Off Eye and Lip Makeup Remover for best results when taking off your makeup. It's an ophthalmologist-tested, non-irritating formula that's great for removing long-wearing products.Was this answer helpful to you
- Q
Is the brown mascara waterproof?
- Asked by Nh
- Official Answer By MACThanks for reaching out! While MAC MACStack Mascara Superstack in Chestnut is flake- and clump-resistant with impeccable wear, it is not a waterproof formula. You can find MAC MACStack Waterproof Mascara on the site for a waterproof and smudge-proof mascara. To enhance the wear of any lash look, be sure to check out MAC MACStack Legit Lift Lash Primer. This conditioning primer helps lift and lengthen lashes before mascara application and would make a great addition to your makeup bag.Was this answer helpful to you

Easy to Apply, No Spider Lashes, Non Clumping,
Hello my lovely readers! I was recently gifted the new M·A·CStack Micro Brush Mascara by Bzzagent in exchange for a review. The M·A·CStack Micro Brush Mascara retails for about $28, and claims that it's clump resistant, layerable, separates and defines lashes, is nonflaking, and lasts up to 24 hour...

Can see the advantages, but not for me
For me, I don't know if I will be repurchasing this mascara. I have used it twice since receiving it and while the brand is great and I really like the color, this mascara is not a great fit for me.

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.

Comments about M·A·CStack Mascara
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
smudges on the face
nobody likes to get black eyes I even stopped putting it on my bottom lashes and it still smears I didn't like this mascara
I would buy this product again! Much better than L'Oreal.
This mascara is so much better than L'Oreal telescopic!
