Frequently asked questions

Discolouration happens when pigments from food, drink and habits attach to your teeth. Stains can be removed in two ways: physically, by gently polishing away surface stains, or chemically, with peroxide that penetrates enamel and breaks down deeper stains.

Our Advanced Whitening Strips, V34 Strips, Whitening Pen and the strips in the LED kit contain 6% hydrogen peroxide. The V34 Colour Correction Serum is peroxide-free. Sets that include strips or the pen contain peroxide.

Hydrogen peroxide penetrates enamel and releases oxygen, which breaks down stain molecules so your teeth look whiter.

V34 uses purple colour-correcting pigments. Purple sits opposite yellow on the colour wheel, so it counteracts yellow tones and makes teeth look brighter straight away. It is a temporary, cosmetic effect.
