NOT ALL PROOF
I paid for the most expensive brand (FORENCOS) because I have tried EVERY waterproof eyeliner that there is -- they weren't really waterproof, sweat-proof or brown. I thought "This is the one! It's the most expensive!" Well, it is almost impossible to stay consistent while I have tried to apply again & again. It can't even do a straight line; isn't consistent in product & it does sweat off, isn't smudgeproof & it doesn't last all day.  You're lucky if it stays on for half an hour.  Lesson learned, trust no one, I am back to using my old faithful, which also isn't really waterproof, but at least it stays on for longer than 30 minutes & costs much less ----Never think it's the answer just because its the most expensive & hyped!
