Why WeSmile

Whitening that shows its work.

A Swedish brand built on one idea: tell people exactly what is in the gel, then let them measure the result themselves. 20,000+ customers in Scandinavia later, that is still the whole plan.

Her personal professional opinion. It does not cover our whitening products.

White teeth. Without the peroxide.

Most whitening gels rely on hydrogen peroxide. Ours never has. Here is the honest difference.

Peroxide whitening

The old chemistry
  • ✕The most common cause of stinging and zingers
  • ✕Can irritate gums and wear on enamel over time
  • ✕EU caps consumer gels at 0.1%, so home results are weak anyway
Still used by most brands on the market.

WeSmile PAP formula

The gentle chemistry
  • ✓Whitens stains without hydrogen peroxide
  • ✓Contains hydroxyapatite, a mineral found in tooth enamel
  • ✓Developed with dentists, registered under the EU Cosmetics Regulation
The formula behind every WeSmile product.

Zero-risk trial · Starter Kit

Every "but what if..." is covered.

The guarantee exists so your first kit is a test we pay for if it fails. It applies to the Whitening Starter Kit, our bestseller. Here is the fine print, unfolded.

Start risk-free · €49.90 →
What exactly do I get back?

The full price of the Starter Kit, to the card you paid with. Return shipping for the kit is the only cost on you.

What if I miss a day of the course?

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

How do you know I did the course?

A timestamped photo against the shade card before every session, plus the used gel pens in the return. Fair for both sides.

Does it apply to strips and the pen?

The photo-verified money-back guarantee covers the Starter Kit. Strips and pen carry the standard right of withdrawal.

Does whitening hurt?

The sting most people associate with whitening comes from peroxide, and there is none in our gel. Sensitive teeth may still notice the course; pause a day and continue.

How many people actually claim the guarantee?

2.4% of kit customers. We publish that number because a guarantee nobody can check is just marketing.
