Jane,

Incredible results. I drink coffee 2-3 times a day which has caused staining on my teeth which this has fully removed. Keep it mind though, this staining wasnt long term which is why i believe it came off so quick & easily. Highly recommend

Frequently Asked Questions
How does it work?
+
Colour theory. Violet sits opposite yellow on the colour wheel, so layering one over the other cancels the yellow out. It is the same principle behind purple toner for blonde hair, applied to your teeth. The pigment sits on the surface and corrects the tone optically.
Is it safe to use?
+
Yes. There is no peroxide, so nothing reacts with your enamel. No burning, no sensitivity, no damage. Free from alcohol, fluoride, SLS and bleach. Vegan. Do not swallow.
Will it work on veneers, crowns or bonding?
+
Yes, and this is where it differs from most whitening. Peroxide only reacts with natural enamel, which is why strips do nothing for dental work. Undertone corrects optically, so veneers, crowns, bonding and composite all look the same as the teeth around them.
How do I place an order?
+
To place an order, simply browse our products, add items to your cart, and proceed to checkout. You can review your order before finalizing your purchase.
When will I see results?
+
Straight away. Swish for 30 seconds and you see the difference when you spit. There is no build up period and no waiting weeks.
Will it stain my teeth or tongue purple?
+
No. The pigment is designed to lift away cleanly when you spit. Your tongue may look faintly violet for a minute or two, which fades on its own.
