The Case for Waterproof Mascara Shop Now There’s a reason best waterproof mascaras are red-carpet and wedding essential. Pros Unbeatable longevity: It doesn’t smudge or run, making it perfect for long events or unpredictable weather. Sweat and tear proof: Ideal for emotional moments, workouts, or humid climates. Holds curl better: For women with naturally straight lashes, waterproof formulas lock in the curl from an eyelash curler more effectively. Cons Harder to remove: You’ll need an oil-based remover or micellar water to break it down. Potential lash damage: With daily use, the tugging during removal may weaken lashes. Heavier formula: Some women find it feels stiffer and less comfortable for everyday wear. In short, waterproof mascara makeup is a great choice when you need performance above all else but it’s not necessarily designed for daily use.
