Okay, we’ll admit it. We love a good prank. If you do too, then this color-changing polish is just what you need. Meet Peek-a-Boo, the most surprising nail polish you’ll find. It goes on clear, but turns to apple candy red when outside. Apply it to your victims when they’re sleeping and watch them react when they’re out in the sun, away from nail polish remover. Peek-a-Boo will be your best kept secret. Not only is it one of our top-selling nail polishes, but Peek-a-Boo is safe too — being 5-Free and never tested on animals.
Much like a flower that blooms when exposed to sunlight, Del Sol's products change colors in the sun using their proprietary Spectrachrome® technology.
Spectrachrome® molecules in the products shift to colors visible to the human eye when exposed to UV sunlight.
Del Sol's Spectrachrome® formula for color change was developed from a concept originally researched by NASA for use in space.
