Review (4/5): Stays on forever
Like many older people, my eyes water a lot because they are "dry" from being irritated by computer use, store air circulation, etc. Because of that, I need a truly waterproof eyeliner. Cherimoya eyeliner really has staying power. The brush makes application easy, too.
If I forget to remove my eyeliner at night, it's still on the next morning. Unlike mascara, it doesn't bleed down to under the eye - so no owl-look the next morning. To remove it I use eye makeup remover on the little round pads that come in a jar. I have found that only the oily ones will work, but I prefer them anyway because they moisten the skin around the eyes.
The only reason I didn't give it 5 stars is because I've noticed after several weeks of use that it is getting a bit dried out. I stirred it and that has helped. I do clean the brush on a piece of tissue every time I use it, and it has stayed as good as new.
