V34 Color Corrector uses color correction technology. Purple is the exact opposite of yellow on the color wheel and is therefore its complementary color, so paint your teeth with a water-soluble purple dye to counteract any yellow undertones. EELHOE V34 is a non-invasive whitening treatment. Just apply v34 Color Corrector to your toothbrush like regular toothpaste, and brush V34's Color Corrector combines two water-soluble dyes to eliminate any shade of yellow for the brightest smile without leaving any residue. EELHOE V34 is suitable for people who want to further brighten their teeth after whitening, or those who already have very white teeth and do not need comprehensive treatment with teeth whitening kits. Oxidizes stains with PAP+ to increase brightness and desaturate yellow stains, while V34 balances warm and cool tones (tints) in teeth to reveal more vibrant shades of white.
