I've tried sooo many high end mascaras and this is by far the best! It holds a curl like *no other*. They even stay curled for a little while after I remove all my eye make up! I have fairly long, straight lashes (my mother is Japanese), so the curl aspect is important! This mascara lengthens more than it thickens giving a lovely, natural look- but the hyper-curl that I get with this product is pretty dramatic. Sometimes when I want extra thickness I apply this followed by a coat of YSL Volume Effect Faux Cils (which makes my lashes super-straight on its own). Awesome mascara! I'd be lost (and straight-lashed) without it!
