Our growing fascination with day-to-night makeup just shifted over to our nails, thanks to a new glittery polish that changes color when the sun hits it. Having bad flashbacks to the mood ring you sported back in middle school? Don't worry: Unlike those kitschy jewels that never changed colors (you know yours was always black), Blaze's Glitz on Madison collection is legit.
The made-in-the-USA brand uses SolarActive technology to create a dramatic transformation. You can go from a funky bright like Seductive Teal to gorgeous emerald shade, Twilight Sparkle; or try Lucky Charm, a seafoam shade that morphs into a super-chic slate. Now if only they could make a mood ring that worked as well as these cool polishes, our fingers would be all set!
