Orly Gel FX Shade Shifter Gel Polish is the amazing new product from Orly. Dark when you're cold, clear when you're hot! Add two coats of Shade Shifter after the traditional colour coats, allow to cure and add the top coat, then watch as your nail colours transform along with your body heat.
Unique to your body chemistry, as you move between cold and warm your nail colour will begin to show through with a gradated effect or tie-dye effect. Seeing is believing!
