Okay, the deal with this mascara is the same of those like "fiber wig" mascara. I have learned to loove this stuff, but it can be tricky. It works & looks best if used with a coat of your HG first so the thin formula has something to bond to, it's magic is these little fibers (you can actually see them on the brush) that stick to the end of your lashes and make them look oh so unstoppable. It really does add lots of length to my lashes but if the little fibers don't do right it can look like you burned some lashed off. Can look natural and didn't smear for me at all...comes off super easy. continued >>

Beautiful lashes as a result of using this mascara. It made them super long. I usually use Full and Soft, which would last a while before drying out and everything but it would crust off during the day. In my attempts to try something new, I came across this one. Several people I see on a day-to-day basis noticed without my saying and complimented how long my eyelashes looked. Unfortunately, there is some ingredient in this mascara that made the roots of my lashes sore and itchy. A couple of weeks after using it, I realized that I was losing too many eyelashes. I suppose it was an allergic reaction. It does NOT smudge and it DOES wash off easily. I am not sure why other reviews are saying otherwise... But I do not have the waterproof one, so that could be why (oddly?)

After I put this crapola on, I couldn't even tell I put mascara on. Wow they need to discontinue this crap ASAP.

Worst mascara on the face of the earth. I try mascaras a lot and i typically don't like them. (I do love Lash Blast though.) This mascara dries so fast and clumps like no other mascara i've ever tried. I would not recommend this mascara to anyone who wants beautiful lashes. Your lashes will look so clumpy and messy. Just HORRIBLE!!!!!

This is unstoppable all right - it smears and smears. It didn't give me any length, and waterproof < HA. I originally went to the drugstore to buy "full and soft" just for my daytime/work look and decided to try this, ugh, what a waste of $$. continued >>

My problem: extreme racoon eye no matter what mascara I use. So Unstoppable Waterprood gave me some hope. Absolutely no smearing, Maybelline claims. Wrong. It did smear, but maybe not to the extent of other mascaras. And the brush was big and fat, but somehow the bristles seemed very sparse. As for thickening and lengthening, it was alright. But since it smears, it's going into the trashcan.

My HG mascara!! Makes my lashes SOOO long, like I'm wearing falsies. And it never smudges... lasts all day. The ONLY thing I can find wrong with it, is it seems to dry out a little too quickly in the tube.

I really like this mascara...I just wish it would have given me a bit more volume. It leaves my lashes soft, and doesn't smudge under any conditions (especially those hot sticky summery days) and never have I ever been left with any raccoon eyes after washing it off.

When I use this after curling my lashes, I end up with straight lashes and I have to curl them again after it dries. I hate this stuff.

i've tried many mascara from Shu Uemura to Artistry. but none impressed me. Those tend to dry up after a couple of months. But this mascara is great. i love the fact that it's so easily washed off by warm water. So, i dun need much time removing it. or even when you accidentally smudge it, u can just use water to remove it. However, it doesn't prove to give me "unstoppable lash" that i hope for. Still, it's quite okay. I'd rather recommend this if you wouldn't want to waste money on expensive products for the same quality you would get.
