This is a great mascara! It makes my lashes much thicker and longer. It's supposed to curl your lashes as well, but given that even a Shu Uemura eyelash curler can't get the job done for me, I wouldn't expect it of a mascara. Another huge plus is that it doesn't smudge on me, even after an entire day. Before this mascara, I used YSL's Mascara Essentiel which was pretty good but always smudged. But anyways, this one also leaves your lashes incredibly natural feeling- instead of stiff and brittle. Oh, and it doesn't irritate my eyes (I wear contacts). The only reason I'm giving it a 4 instead of 5 is that it tends to clump a bit, but otherwise it's great.
