Sky High is right!
Color: BLACKEST BLACK, Size: 0.24 Fl Oz (Pack of 1)
This mascara truly delivers. The formula dries quickly without flaking or transferring, and the slim applicator brush makes application effortless and precise. I wore it all day and well into the night, and it stayed flawless the entire time with no touch-ups needed. Long-lasting, lightweight, and high quality. I will definitely be repurchasing.

Great mascara
Color: BLACKEST BLACK, Size: 0.24 Fl Oz (Pack of 1)
I’ve tried a ton of mascaras but this one definitely far exceeds my expectations compared to other mascaras. I wouldn’t go as far as to say your lashes will be unbelievably long and fake looking- but it definitely adds volume and depth to my lashes while maintaining a real lash look. I don’t have issues with clumping or lash breakage with this mascara. It washes off easily without leaving you with raccoon eyes. Also it does not cause eye sensitivity for me.

Best mascara I've tried!
Color: VERY BLACK, Size: 0.24 Fl Oz (Pack of 1)
This is hands down my favorite mascara! It gives amazing length and volume without feeling heavy or clumpy. My lashes look so much longer, and it lasts really well throughout the day. I keep coming back to this one because it works better than many more expensive mascaras I’ve tried!

Good Everyday Mascara
Color: BLACKEST BLACK, Size: 0.24 Fl Oz (Pack of 1)
I’ve been using the Maybelline Lash Sensational Sky High Washable Mascara for a couple of weeks now, and overall I’m really impressed.
The biggest standout is the length. It genuinely makes my lashes look noticeably longer without needing multiple coats. The flexible brush does a great job grabbing even the smaller lashes, and I didn’t have much issue with clumping as long as I applied it carefully. It also holds a curl better than I expected for a washable formula, which is a big plus.
Another thing I appreciate is how lightweight it feels. My lashes don’t get that heavy, stiff feeling some volumizing mascaras can cause. It’s also easy to remove at the end of the day, which makes it great for everyday use.
That said, it’s not perfect. While it does add some volume, if you’re looking for a very bold, thick lash look, you might find it a bit lacking. I also noticed a tiny bit of smudging under my eyes after a long day, though nothing too extreme.
Overall, this is a great mascara for length and a more defined, lifted look. I’d definitely repurchase, especially for daily wear, but I’d pair it with something more volumizing for special occasions.

Best mascara on the market.
Color: VERY BLACK, Size: 0.2 Fl Oz (Pack of 1)
I have been buying a more expensive product from Loreal. I saw a tv commericial on the Sky High and tried it. Wow! I don't normally write product reviews, but this is great. This is the best mascara on the market today. The product I get from Loreal was 4 times the price and dried out half the time when I receive. I am just amazed this Sky High is this good. It thickens and makes the lashes longer. I have tried every brand out there, but will continue to use this.
