No Smudging
The last thing you want to happen after applying mascara is to have it smudge. This can sometimes happen before you're even done applying it. By having waterproof mascara, you don't have to worry about incidentally rubbing your eye or even washing your face with plain water.
No Racoon Eyes
When mascara runs and gets in your eyes, rubbing it can give you racoon eyes. Sometimes this is actually done so on purpose for a certain look. But if you're not going for that look, waterproof mascara can keep this from happening unintentionally by not running due to sweat, tears, or other incidental wetness.
Still Easy to Remove
While it may not come off with plain water, waterproof mascara is not that hard to remove. All you need is a simple moisturizer or soap. Honestly, to thoroughly remove regular mascara, you probably still need to do this anyway. So, why not just get the kind that helps prevent annoying issues and save yourself the trouble?
