This opalescent Nail Brightening Treatment is formulated with vitamin E and lemon fruit extract. It helps to exfoliate nails. Mellow the Yellow formula scrubs the surface of your nails to help them appear brighter and smoother. The pearly white nail color and nail treatment formula gives the effect of a shimmery manicure look while working hard to brighten the look of nails. How do I use it: Apply one coat of Mellow the Yellow to clean, dry, bare nails. For a more opaque look, layer two or three coats to enhance the pigment. Let the nail treatment dry completely. Can be worn alone, or to provide the look of extra shine, apply with butter LONDON Hardwear Shine Topcoat (not included). The curved brush makes for easy application and a flawless-looking finish.
