Purple shampoo cancels brass in blonde hair. PERO's Violet Tone Technology does the same for your smile — one chewable tablet neutralises yellow tones on contact, so teeth look brighter the moment you spit. No tube, no water, no fluoride.
Violet Tone Technology works on a simple fact: purple and yellow sit opposite each other on the colour wheel. As you brush, the tint meets yellow-toned enamel and visually cancels it — the same principle as purple shampoo for blonde hair. Underneath, PAP lifts the everyday surface staining from coffee, tea and wine. Nothing is stripped from your enamel, and the tint rinses clean away.
Drag the slider to brush. The warm tones cancel out as you go, and your smile reads brighter on contact — no peroxide involved.
Purple (P) sits directly across from yellow (Y). Layer one over the other and the eye reads a neutral, cleaner white.
Everything in, nothing to hide — and the tube, the fluoride and the water filler left out on purpose.
The same mineral that makes up most of your enamel. Originally researched by NASA and used in Japanese toothpaste for over 40 years — a fluoride-free way to look after teeth daily.
Phthalimidoperoxycaproic acid — the surface-stain active from professional whitening strips, formulated here to target staining from coffee, tea and wine. Peroxide-free.
A naturally derived sweetener that doesn't feed the bacteria behind cavities, so it earns its place beyond taste.
A gentle polish, with a little calcium carbonate and a peppermint–spearmint blend for a cool, fresh finish.
Pop one tablet in your mouth and chew until it forms a paste with your saliva.
Wet your toothbrush and brush as normal for a full two minutes.
Rinse with water. One tablet morning and night — 90 per tin, about 45 days.
Standard toothpaste is mostly water in a single-use plastic tube. Remove the water and you get a concentrated dose that ships flat, stays dry in a sealed metal tin, and travels without counting as a liquid.

No. The purple tint rinses away completely when you spit. What stays is a cleaner, brighter-looking smile — it won't stain your teeth, tongue or sink.
Yes. Every tablet is built around hydroxyapatite, the mineral that makes up most of your enamel, with no fluoride. Hydroxyapatite is the fluoride alternative that's been standard in Japan for decades.
The purple formula adds two things: PAP, the surface-stain active from whitening strips, and a purple tint that cancels yellow tones as you brush. A plain tablet is mineral daily care without the brightening layer.
One per brush, morning and night. Each sealed tin holds 90 tablets — roughly a 45-day supply for one person.
The formula is SLS-free and peroxide-free, which many people with sensitivity find gentler than foaming, bleaching alternatives. As with any oral-care change, check with your dentist if you have specific concerns.
