Blaze Nails Solar-Powered Glitter Collection: This isn’t a new line, but Beauty High discovered a company called Blaze, which produces nail polishes that change color in the sun. And their latest collection, Glitz on Madison, is glittery to boot. (See above–the “before” color is lighter than the “after” color). So if you can’t decide between two colors, and also love some bling in your polish, this is the collection for you. Get them here, $12.95 each.
