Volumizing mascara
Got mascara as a free gift will definitely purchase again. It goes on nicely and gives volume. I really like it. That said, All these dramatic reviews are ridiculous. These people clearly don’t have real problems. If you get mascara on something other than your eyelashes grab a q-tip and wipe it off like the rest of us do. I would not trust reviews from people using language like horrid or really disappointed. There are things in this world that are horrid and disappointing but mascara is not one of them. So this hard working woman enjoys this mascara and will purchase in the future. I hope your customers learn how to find some joy in life and read a book.

hard pass
I’m in my 50’s. I love my eyeliner and mascara. I don’t leave home without either of them. I’ve tried many a mascara in my lifetime both cheap and expensive. This is a hard pass. While I love MAC and I am a loyal customer of their studio fix foundation, lipliners, pencil sharpeners, mascara (extended play gigablack mascara is all I use for my lower lashes) …with that said, I absolutely hate this mascara. It’s awful. I cannot figure out how to apply it without it going spidery on me and straight up globby. I feel like I’m in the fifth grade putting mascara on for the first time not knowing how to apply it lol. And I know how to do my makeup.
Guerlain mad eyes and Maybelline Sky High are two of my favorite mascaras. I love a buildable high impact mascara for that wow factor. I have short lashes and small eyes.
MacStack isn’t it.

I was pleasantly surprised by this mascara! The Denim Stack shade adds a fun pop of color that really enhances my eyes. It goes on smoothly, doesn’t clump, and lasts all day without flaking. The packaging is super cute and feels high-quality. I received this product for free from MAC COSMETICS for testing and review purposes.

Lovely shade of blue
I guess I’m a little picky when it comes to my mascara. I have camel lashes that are relatively long but stick straight down, so you can’t really see them. The lash curler is my best friend. I require from my mascara to hold that curl. Typically, it ends up having to be a waterproof formula of some sort. My standards are specific, yet reasonable. Here are my findings on this guy:
Pros:
•slightly lifts lashes on its own without first curling.
•the demon blue color is so nice! It’s so deep, almost black.
•color coats lashes evenly.
•separates lashes and defines.
•the wand is very comfortable to use.
•the packaging is sleek and elegant. It’s long but doesn’t take up too much space.
Cons:
•theres a fine line that can be crossed when using this mascara that leaves you with “spider lashes.”
•the formula doesn’t seem to be water resistant or sweat resistant, so it smudged under my eye.
Overall, I’d say this is a wonderful bottom lash mascara or a great topper to your staple. I liked layering this blue on top of my in extreme dimension waterproof. The color is gorgeous and I’m excited to try others. I’m hopeful for a waterproof formula and will run to try!

Terrible. Like Elmer’s hlue!
I bought two thinking I would love it. It went on ok and actually did make my lashes look nice.
The problem is it takes several washes to get your eyelashes clean at night!!’ My Gosh, it’s like glue. Not wanting to beat up my eyes and lashes in order to remove it, I’m returning both. Will have to try something else.
