I use this awesome mascara call Kiss Me made by Blinc. It is a really cool formula that creates little tubes around each lash, so it never smudges and is completely tear-proof. It also comes off really easily with just warm water and a bit of rubbing.
The even better thing about this mascara is it comes in terrifically vivid versions of blue, green and purple, as well as the standard black and brown.
It is a bit pricey ($26.50 cdn, $24 US) but I think it is totally worth it. I found a great website to order it from in Canada – check it out and order more than one tube for free shipping. Enjoy!
