[EXPERIENCE THE LASH REVOLUTION]: NEW 4D Silk Fiber Eyelash Mascara gives you insane length and volume without extensions, fillers, or falsies. Our professional formula contains lengthening fibers that can be applied in layers to create lashes that appear to keep growing and growing. [NATURAL, HYPOSENSITIVITY]: Eyelash Mascara has a water-based formula, instead of the oil-based formulas you often see in mascaras. We chose this water-based formula because it has a neutral pH, making it healthier for the delicate skin around your eyes. [SLIM BRUSH HEAD]: This water-based mascara dries quickly and won't cause your eyelashes to clump or stick together the way oil-based formulas can.Its designed to go on smoothly and easily. It comes with a medium-sized silicone brush thats slightly tapered so you can easily reach all your lashes. [WATER-BASED FORMULA]: This mascara set is waterproof, really long-lasting, and stays gorgeously long and thick, even through rain, tears, and sweat. Easy to remove with a makeup remover without damaging your lashes.
