The Science
Color theory, not chemistry.
Purple and yellow sit opposite each other on the color wheel. When they meet, the yellow cancels out — visually, instantly, without touching your enamel.
Opposites cancel on contact
Yellow-toned teeth reflect warm light; purple pigment absorbs it. Layer the two and the yellow cast disappears the moment the rinse touches your teeth — the same principle that fixes brassy blonde hair, borrowed for your smile.
Three actives working underneath
While the color does its job up front, Xylitol, Hyaluronic Acid, and Pyrophosphate support tooth health, gum hydration, and tartar prevention between brushes. Oral care and color correction in one sachet.
Gentle enough for dental work
Because the effect is optical, not chemical, it reads the same on natural enamel, veneers, crowns, and bonding — without the shade mismatches whitening treatments can leave behind on restorative work.
The Routine
Four steps. Thirty seconds.

FAQ
Questions, answered.
Everything you might want to know before your first rinse.
How fast will I see a difference?+
Right away. The effect is instant and cosmetic — purple pigment neutralizes yellow tones on contact, so your smile looks visibly brighter the moment you rinse. For lasting brightness, use one sachet daily as part of your routine.
Is it safe for veneers, crowns & bonding?+
Yes. Because this is optical color correction rather than chemical bleaching, it reads the same on natural teeth and dental work — without the shade mismatches whitening treatments can leave behind on restorations.
Will it make my teeth sensitive?+
No. There's no peroxide and no alcohol — the two usual causes of sensitivity and burn. The formula is designed to be gentle while it freshens and brightens.
How does the purple actually work?+
Purple and yellow sit opposite each other on the color wheel, so purple visually cancels yellow tones on contact — the same principle behind purple shampoo for blonde hair. It works on the surface, without bleaching or stripping enamel.
How do I use it?+
Tear open one sachet after brushing, swish for 30 seconds, and spit. The purple rinses away and the brightness stays. One sachet a day, 20 per box.
What if it doesn't work for me?+
You're covered by our refund policy. If you're not satisfied, reach out and we'll make it right — no questions asked.
