Ingredients

PAP (phthalimidoperoxycaproic acid) 12 % does the whitening. Hydroxyapatite, a mineral close to the tooth's own surface, is in the formula, with potassium citrate, xylitol and peppermint oil. Vegan and cruelty free.

Whitening you can measure.

A tray that times itself

Ten minutes, then it stops. Contact time decides day twelve.

A 20-step card

The method dentistry has used since 1956: match, note, match again.

Unlike most PAP kits, the dose is stated.

PAP is an ingredient, not a dose. Independent lab testing puts numbers on it:

Whiteness index · 12 % PAP8.82
Hydrogen peroxide · 37.5 %4.48
Carbamide peroxide · 35 %4.16
Read the evidence, including what goes against us

Twelve evenings. One reading.

Ten minutes in front of whatever you were going to watch anyway.

Day 1
Set the baseline

Brush, hold the card up in daylight, photograph the match.

Days 2-11
One session a night

A dose along the tray, press once, it stops on its own.

Day 12

Same card, same light, same phone. The match is the reading.

How to use.

Ten minutes a day for twelve days. Four steps, and nothing to learn.

1Melina Galant
Brush

Any toothbrush will do. Brush and dry your teeth first, so the gel grips clean, dry enamel.

2Ella Holmberg
The gel

Twist the pen and brush a thin layer onto the front of each tooth you want whiter. Thin is right, more gel is not more whitening.

3Wilma Tillander
The light

Slip the tray in and press once. The ten-minute timer runs the session and switches itself off.

4Thyra Lundin
Measure

Before each session, hold the shade card to your teeth and take a photo. That photo is what the guarantee is judged on, and it is where you watch the number move.

The study behind the 12 % claim

Llena et al., J Funct Biomater 2026;17(2):104, Universitat de València. Independent, no external funding. It tested another manufacturer's 12 % PAP gel, not ours. Nine further studies, including the ones that disagree, are on the science page.

Questions?
Fair ones.

Straight answers, including the ones that cost us a sale.

The full science, every study cited → The Reddit questions, answered →
Isn't PAP in every whitening kit now?

It is in a lot of them, and that is exactly the problem. PAP is an ingredient, not a dose. Almost nobody prints theirs.

In an independent laboratory study, 12 % PAP moved the whiteness index 8.82, more than the peroxide gels dentists use (a lab study on extracted teeth, testing another maker’s 12 % gel, not ours). In a separate 2026 study, a PAP+ kit whose label does not state its strength produced no significant whitening, even used for twice as long as its instructions say. Same ingredient on the label, different outcome on the tooth.

Ours is 12 %, and it is printed on this page, because a percentage you cannot read is a percentage you cannot judge. The study, including what goes against us →

Does it hurt?

We cannot promise it will not. What we can say: the sting people remember from whitening is a peroxide story, and there is no hydrogen peroxide in this gel. If your teeth are already sensitive, use mode two and ask a dentist first.

How fast will I see something?

Most people see a difference within the first few sessions, but the number that counts is day twelve, because that is the one the guarantee reads.

Does the LED light actually do anything?

The light is inspired by violet-LED research: a 12-month randomised clinical study (Lopes et al., Frontiers in Dental Medicine, 2024) found violet LED light (405-410 nm) alone whitened teeth with minimal sensitivity, and did even better combined with bleaching.

The honest part: that study tested other equipment, and we have not published our own tray's wavelength. What it certainly does is hold the gel in place for a fixed ten minutes, and contact time does matter.

Can I use it with fillings or crowns?

Safe to use, but whitening only works on natural enamel. Visible work at the front? Ask your dentist about the order to do things in.

What if I miss an evening?

Fine. The guarantee asks for twelve sessions within twenty days, so there is room for a busy week.
