Waterproof black eyeliner is a cosmetic product designed to define and accentuate the eyes with a bold, intense black color. It's specially formulated to resist water, sweat, and smudging, making it ideal for long-lasting wear, even in humid or rainy conditions. The formula typically has a rich, pigmented texture that glides on smoothly and dries to a smudge-proof finish. Whether used on the upper lash line for a classic cat-eye look or along the waterline for a dramatic, bold statement, waterproof black eyeliner helps create striking eye makeup that stays put throughout the day or night. It’s available in various forms such as pencil, gel, liquid, or felt-tip pen, providing versatility for different application techniques.
