Here's what that means:
* It will smudge and run: If your eyes get wet, whether from rain, sweat, or tears, non-waterproof mascara will likely smear or run.
* It's easier to remove: Non-waterproof mascara can be removed with regular makeup remover or even just soap and water. This makes it a good choice for everyday wear.
* It can be more gentle on lashes: Some people find that waterproof mascara can be drying or irritating to their lashes. Non-waterproof mascara is often formulated to be gentler on sensitive eyes.
In short, if you're looking for a mascara that is easy to apply and remove, and you don't need it to be waterproof, then non-waterproof mascara is a good option.
