Waterproof Vs. Non Waterproof?
Waterproof has become the new norm for most lip products, but there still are some waterproof options, especially when you're dealing with traditional lipsticks. Some people have problems removing waterproof lipstick which is why they prefer an easy to remove formula, but just as it comes off easy with water, it will also come off easy with drinking, eating, kissing or anything else involving your mouth.
Pro Tip: Remove waterproof lipstick easily with an oil based makeup remover or, in a pinch, baby oil.
