V34 Colour Corrector utilises colour correcting technology. Purple is directly opposite yellow on the colour wheel and is therefore its complementary colour, so a water-soluble purple dye is applied to your teeth to cancel out any yellow undertones. EELHOE V34 is a non-invasive brightening treatment. Simply apply the v34 Colour Corrector to your toothbrush like a regular toothpaste, and brush V34's Colour Corrector's combination of two water-soluble dyes allow for any shade of yellow to be cancelled for the brightest smile, without leaving behind any residue. EELHOE V34 is intended for people who are looking to further brighten their teeth post-whitening, or already have a very white tooth shade and dont require a full treatment from the Teeth Whitening Kit. Oxidising tooth stains with PAP+ increases the lightness and reduces the saturation of yellow stains, whereas V34 balances the warm and cool tones (hue) in your teeth to reveal a more vibrant shade of white. 1x V34 Color Corrector.
