This is a FANTASTIC mascara made by the people who really know how to do their makeup! I've tried a variety of both HE and d/s mascara in the US, and most either don't do jack to my lashes, or they don't hold curl at ALL. even some of the waterproof mascaras are rather wimpy.
A few months ago i visited Japan and finally picked up the Kiss Me Heroine Long & Curl mascara, as well as the Volume & Curl. V&C ended up being my HG, but the L&C is quite fantastic as well!
Unlike the V&C, this mascara gives me minimal volume to my lashes. Instead what it does quite well is hold curl and FAN OUT my lashes. the bristles on the wand is really thin so it works great at keeping my lashes not clumped together. It lengthens my lashes but not by a lot, but i can totally forgive that when it does such a fantastic job with holding curl and fanning out my lashes. I like to use this during the day for work to give a rather soft look due to the almost feathery effect it gives me.
Note i am asian so I hae stubby asian lashes that doesn't hold curl, and also i have very THIN and few lashes. I believe those with more lashes or thicker lashes would love this mascara, as it helps with keeping lashes separated and curled. for me since my lashes are thin and decently long, i mainly benefited from the separation and curl holding.
One thing to note is that I noticed if I layer more than 1.5 layers or so, it would start to clump at the tip and give me a spidey look. ^^;;
overall this is a fantastic mascara. In the US it's a bit more pricy, but in Japan it varies from 1000yen (at the airport) to around 1200yen. Personally i think it is quite worth the money!
