It adds fibers to your lashes with every application. Love it.
I have never used this product but based on the reviews and what I have seen about it, It looks like I would LOVE it.
This is fantastic mascara. It's one of the few make-up products I really splurge on. The product is made of tiny fibers that attach to your lashes, like brush on eyelash extensions, but it feels just like you've put on mascara - done in 10 seconds. I love the look of eyelash extensions but I never want to mess with actually putting them on. It lengthens without clumping and is very easy to remove with facewash & water. I especially like that it doesn't end up giving me raccoon eyes - it doesn't smudge or run while wet. It's worth the price. You can find it at Sephora.
