The register

Unproven Claims

Somebody has to write down what was actually tested. Every entry here takes one beauty claim, restates it as a proposition somebody could go and check, and records what turned up — including, often, that nobody has looked. No brand is named in a verdict. Nothing here is sponsored, and nothing here links to a shop.

The useful column is not the verdict. It is the one next to it, which says what kind of evidence is missing — because “there is no evidence” is nearly always false, and the accurate answer is usually that the study exists and belongs to something else.

Visible light from the sun does cause pigmentation. That evidence belongs to sunlight, not your monitor, and was carried across without a trial.

Where this stops

This register records the state of published evidence. It does not tell you a product does nothing, and it never says a company is lying — both would be claims about the world that would need proving, where “we searched here, on this date, against this bar, and found this” is a claim about my own reading and can be checked by anyone who repeats it.

The bar is written down in advance, so “nothing met it” means something: A human study, published and peer-reviewed, with a comparator — placebo, vehicle, or an active with its own evidence — reporting the endpoint the claim is actually about. In-vitro work, animal models, uncontrolled before-and-after series, consumer-perception surveys and unpublished supplier data are read and reported, but they do not clear the bar on their own.
