Colour Corrector teeth whitening Foam

What is is: The Colour Corrector teeth whitening Foam neutralises yellow tones and brightens tooth shade through colour correction technology. We've cancelled yellow stains. 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. V34 Color Corrector Foam is also vegan and cruelty-free. How to use: 1. Clean your teeth. Brush your teeth with a fluoride toothpaste and floss to remove any food debris or plaque. 2. Apply the foam. Apply 2 pumps of foam directly into your mouth and swish for 15 seconds. 3. Spit out the foam. Do not swallow the foam. 4. Repeat as needed. You can use V34 Color Corrector Foam as often as you like, but it is recommended to use it twice a day for best results.
