Get a two-for-one manicure with the Sun Switch collection of UV reactive, shade-shifting nail polishes from Ciaté London. The next-generation nail lacquer is formulated with patented colour-changing pigments that adapt with the sun’s rays (even on cloudy days!), switching between two different hues when your indoors and outdoors. ‘Marshmallow’ lays down an even coat of creamy white that transforms into a delicate blush pink when you step outside.
