favorite high end mascara of all time! i would say it focuses on volume AND length but i would say more volume which is better in my opinion, can't wait to try the elevated one!

Great mascara. It's the only one I've used for years!!
Not good
I really wanted to like this mascara, used it by itself, my lashes lost their curl, combined with another mascara and it clumped my eyelashes, let it dry a little because the formula is too wet and nothing, bottom line, I ended up throwing it away

Best waterproof mascara I have found.
I will return this product
Doesn't work Too heavy for my eyelashes pp
