I've read that it is unsafe to use eyeliner on one's waterline. I've also heard that it's safe if you use an eyeliner that's "Waterline Safe." What does "Waterline Safe" mean? Is it truly safe, or is it always bad to put eyeliner there?
"Waterline safe" is just a dumb marketing term you could cause an infection and even blindness trust me no matter how many makeup artists tell you to line the waterline dont! The water line is a mucus membrane and works to keep itself clean of any debris which is what eyeliner will be to it. Besides when you put stuff into the waterline it always ends up getting stuck annoyingly in the tearduct like dirt would! User beware on this one people!
