We sell few products. That is the result, not the starting point.

The red light therapy market is saturated with devices whose irradiance nobody publishes, sold with invented reviews and illegal therapeutic promises. Here are the rules we hold ourselves to so we are not part of it.

14 days to try it at home and send it back if it does not fit

2 years of warranty on every device in the range

DOI on every study we cite, never a second-hand summary

0 reviews, ratings or counters hand-written on this site

Four principles

What decides whether a product joins the range.

Evidence before argument

We do not sell a use case the literature does not document. Where research is thin or contradictory, we write that down instead of rounding it up — which is exactly what our Science page does, limitations block included.

One format per real use

A knee wrap exists because a panel lights a bent knee badly. A mask exists because holding a panel in front of your face for twenty minutes does not survive a real week. We do not add a format to pad out a catalogue.

Numbers you can check

Exact wavelengths in nanometres, irradiance with the distance it was measured at, area covered. An LED count on its own means nothing, and we refuse to headline it as though it did. The comparison method is set out in how it works.

The right to say no

Most devices we test never go on sale. A product that delivers less than its spec sheet, runs too hot to be worn, or whose manufacturer refuses to share measurements is dropped without discussion.

Commitments you can verify

What we do, and what we refuse to do.

We cite every study with its DOI

The permanent identifier of the paper, opening the original publication. Not a blog post summarising a newswire summarising a press release.

We flag a study's limitations

A twenty-person sample, manufacturer funding, an effect measured on a biological marker rather than on how you feel: it is written next to the result, not in a footnote.

We publish irradiance with its distance

Irradiance without a measurement distance is a number with no usable unit. It always appears as mW/cm² at X cm.

No hand-written reviews or ratings

Ratings shown on this site come only from verified customer reviews. Until there are any, there are no stars. Publishing a fictitious rating is a misleading commercial practice under French consumer law.

No therapeutic promise

Our devices are wellness products. They do not diagnose, treat or cure any disease, and we will never write otherwise to make a sale.

No retouched before / after

No retouching, no lighting change between the two shots, no generated image. Absent an honest photo, we would rather show nothing.
