Waterproof mascara is a type of eye makeup designed to resist moisture, making it ideal for situations where tears, sweat, or water exposure may occur. It typically contains special waxes and polymers that create a barrier, allowing the mascara to stay in place longer than regular formulas. This product is popular for various occasions, such as swimming, exercising, or attending events where crying might happen. However, removing waterproof mascara often requires a specific makeup remover or oil-based cleanser, as regular soap and water may not be effective in fully eliminating it.
