Colour correction all starts on the colour wheel, where purple and yellow are complementary colours opposite to each other. Applying purple onto your teeth will neutralise the yellow undertones and cancel them, revealing a perceptively brighter shade of white. Pretty cool right?

The V34 formula blends two water-soluble dyes, capable of tackling any shade of yellow. The result? The brightest smile you can imagine, and the best part is, it doesn't leave any residue behind.
