NailKale NailBright in Knightsbridge Mewsadds a flush of copper to the nails for a new take on the naked nail trend. The polish is lightly tinted in the base and blended with reflective glass blur pearls to ensure the nails radiate just a touch of colour. NailKale NailBright can be used alone or as a top coat to add a pretty tint to paler shades. The formulation is not only enriched with kale, but is also powered by bee pollen. Made by honey bees, bee pollen is considered one of nature's most pure products.
