Ingredients

PAP (phthalimidoperoxycaproic acid) 12 % does the whitening, without hydrogen peroxide. Hydroxyapatite, a mineral close to the tooth's own surface, is in the formula, with potassium citrate, xylitol and peppermint oil. Developed with dentists. Vegan and cruelty free.

Full INCI: Aqua · Glycerol · Phthalimidoperoxycaproic Acid (PAP) · Carbomer · Disodium EDTA · Hydroxyapatite · Sodium Hydroxide · Titanium Dioxide · Potassium Citrate · Povidone (PVP) · Triethanolamine · Xylitol · Mentha Piperita Oil

A session with the LED booster

Same tray. Same card. Another twelve evenings.

Whitening is not a one-off. Coffee and tea keep working on your teeth, so a new course every few months keeps the shade you reached. You already own the hardware.

The routine

Ten minutes. Twelve evenings.

Exactly like your first course.

Step 1
Brush

Clean, dry teeth before every session.

Step 2
One dose

About 0.75 ml spread along the front of the tray, upper and lower.

Step 3
Tray in, press once

The booster runs ten minutes and switches itself off with a beep.

Step 4
Rinse and read

Rinse your mouth and the tray. Check the shade card in the same light as before.

Sensitive gums?Use the booster's second light mode, blue and pink.
The LED booster with the tray attached

Unlike most PAP kits, the dose is stated.

PAP is an ingredient, not a dose. Ours is 12 %, in every WeSmile gel. Independent lab testing of a 12 % PAP gel put numbers on what that dose can do:

Whiteness index · 12 % PAP8.82
Hydrogen peroxide · 37.5 %4.48
Carbamide peroxide · 35 %4.16

Llena et al. 2026, lab study on extracted teeth. It tested another manufacturer's 12 % PAP gel, not ours.

Why the number matters

Between courses, keep it.

Questions?
Fair ones.

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

Can I reuse my old booster and tray?

Yes, that is the idea. The refill is gel only and works with the Starter Kit tray and LED booster you already own.

How often should I do a course?

Whenever the shade card says you have slipped. For many people that is every three to six months, depending on coffee, tea and red wine.

How much gel per session?

About 0.75 ml, spread thinly along the front of the tray. More gel is not more whitening.

Is it the same gel as the kit?

Yes: PAP12%, the same stated dose and the same ingredients, listed in full above.
