I've finally found the eyeliner that lasts ALL DAY!!! I feel like I'm the only one of my friends that has this problem, but i have oily skin and every eyeliner I've tried (and trust me, that's alot of eyeliner) runs by midday. It makes me feel like a racoon.
This stuff is amazing. It takes getting used to because it comes in a little pot and you apply it with a brush (reminds me of a calligraphy set). Once it dries, it's set!! I got it in espresso ink, which is great brownish-black, for $18. The only downside is that the brush is sold separately (another $18) but I got my brush from The Body Shop which i think is a much better brush (and cheaper - $10) as it makes a fine thin line.
