WHY IT WORKS SO WELL
-
1COLOUR CORRECTION
Purple pigments neutralise yellow tones on contact. It's the colour wheel — exactly what purple shampoo does at the hairdresser's.
-
2MORE THAN FRESH BREATH
Xylitol, hyaluronic acid and pyrophosphate: gums are hydrated, plaque is less acidic, and coffee stains no longer settle in.

320 SACHETS PER BOX
One sachet a day. Pre-measured, individually sealed, small enough to fit in a handbag or a desk drawer.
They've tried it. Here's what they say.

I did the first sachet on a Sunday night, not expecting much. I spat it out, looked in the mirror, and called my girlfriend over to come and see.

I do it after brushing, it hasn't changed my routine at all. And it doesn't stain your tongue or lips, which was my worry.

Strips, I'd given up after three days, they hurt that much. With this, nothing. Not a twinge, not a hint of discomfort.

My dentist had warned me no whitening would work on them. It's the first time my smile has been the same colour all over.

I was sceptical. After a month, what blew me away wasn't the first day, it's that my teeth no longer start from the same shade each morning.

I didn't even realise I was closing my mouth in every photo. It was my sister who pointed it out, last month.

Common questions
Is it going to hurt? I gave up on strips after three days.
No. No peroxide, no alcohol, no SLS. Nothing penetrates the tooth: the product only works on the surface of the enamel. That's precisely why there's no twinge and no sensitivity — there's nothing to strip.
How long before I see a difference?
From the very first rinse, as you spit it out. It's an optical correction, not bleaching: there's nothing to wait for.
And at the same time, the formula stops new stains from settling in. After a month, it's no longer just the morning effect that shows: the base shade itself stops darkening.
What about my veneers or crowns?
Yes, and it's the one place on the market where we're the only option. No whitening can work on a veneer or a crown: these materials aren't porous, there's nothing to penetrate. Optical correction doesn't penetrate anything — it sits on top. On enamel, on ceramic, on composite, all the same.
Does it damage the enamel?
No. There's no oxidising agent in the formula: nothing strips, nothing penetrates. Xylitol, hyaluronic acid and pyrophosphate are care actives, not abrasives. If you're unsure, it's an easy question to put to your dentist.
How long does delivery take to arrive?
Dispatched within 24 working hours. Tracked delivery to your door or a local pick-up point in 3 to 5 working days across the UK.
And if it doesn't work for me?
30 days to see for yourself. If you're not happy with the result, we refund you — no proof, no questions asked, box opened or not. You've already paid once for something that didn't work. It won't be twice.
