you should check out Make Up Forever's Aqua eyes eye pencils or Avon's super shock long-wearing gel eyeliners. I don't think you'll be dissapointed.
But remember if you're using kohl on your waterline, while it is less of an irritant it is also lacking in staying power. that's why it is a good idea to "set" your eyeliner by running an eyeshadow in a similiar color very close to the lashline.
hope this helps!

I like Sephora's Waterproof Retractable Eye Liner because it is one of the few that claims to be waterproof and actually is. I can swim with it on and it last all day long, even in the summer months. I love that it is retractable and has a smudge brush on the end.
i am obsessed with MAKEUP FOREVER Aqua Eyes and religiously use it for the past 3 yrs. They have many shades to choose from so you can find the one that suits you best and you dont ever have to worry about it smudging all over. I can always depend on it to enhance my smoky eye look!
I like to use tokidoki's perfetto eyeliner. It's like a marker so it doesn't smudge and it's also waterproof. It also can be used as a marker to draw pictures on your skin, whenever I get bored I just pull it out and start doodling
Do you wear it on the inside of your eyes?
I've been using Buxom's Insider Eyeliner ... its amazing and comes in tons of different colours ) You can also use it on the inside of your eyes.
MAKE UP FOR EVER's aqua eyes eyeliner pencils are incredibly long wearing through everything! Sweat, tears, you name it, it doesn't budge until you take it off with eye makeup remover.
