Never keep mascara for more than six months because it’s a haven for bacteria, and if you’ve had any type of infection, such as pink eye, don’t reuse it because you could reinfect yourself. Also, never add water or any other liquids to the bottle if your mascara begins to dry out. To get the most out of your mascara, keep it tightly closed and stored in a dark, cool place, and don’t pump the wand in and out of the tube — you’ll simply be exposing the product to more drying air and airborne bacteria.
