I always use my Blacktrack f/l on my waterline. It doesn't wear much throughout the day; I do use a pencil liner over top of it though, to make it last even longer.
The only one that is actually waterline approved are the new Kohl Power liners.. so I highly reccommend those if you're trying to go for something safeeee. But if you really don't care, Smolder Eye Kohl is a popular one.
I use everything from pigments to eyeshadows, tecknkhols and ordinary pencils. The only thing I dont use for obvious reasons are glitters and glitter liners.
