The Wonder Perfect 4D Waterproof Mascara provides volume, length, curvature and definition to the eyelashes for a perfect look in 4 dimensions, completely and visibly improving the length and thickness of the eyelashes day after day. The more you wear it, the more your eyelashes become beautiful. Another advantage? Its water-resistant and "emotion-resistant" super formula can handle all of your everyday setbacks. This mask remains unfazed by water, humidity, heat or tears (from happiness, of course!). Trust her, she will never fail you.
