PURPLE GLOW IN THE DARK NAIL POLISH Remember when glow sticks were the coolest things you’d ever seen? Something about that fluorescent little wand captivated us, and that’s why we still get a little thrill every time we come across anything with a tagline that reads “glow in the dark”. Milky Way is a purple glow in the dark nail polish top coat. It is a natural light white polish that is best worn over other colors (best over light shades such as white). Milky Way glows purple in the dark. Nail swatches show 3 coats of Milky Way over a white base coat. In order for the nail polish to glow it will need to be exposed to a light source to charge it. Sunlight is the most effective, but a bright light bulb will work as well. The longer the polish is left in the light, the longer it will glow!
