US brands cite a person, Korean brands cite a test

The two sides of this corridor borrow authority from different places: US-origin brands invoke a dermatologist on 8.4% of their products against 1.6% for Korean-origin brands, while 17 of 19 Korean-origin brands use clinical-testing language somewhere in the catalogue against 11 of 18 US-origin ones. One names a professional, the other names a procedure.

A Korean brand translating its own claims literally arrives with a study nobody asked for and without the person American shoppers use as a shortcut for whether to trust it.

Exceptions and limits

Japan’s PMD Act treats advertising, describing or circulating statements that lead to the false impression that a physician or other person has certified the efficacy, effects or performance of a cosmetic as falling within its prohibition on false or exaggerated advertisement, and that prohibition binds any person rather than only the seller.

Held since August 5, 2026What kind of message reads as credible here. The earliest date we are willing to say this held. It may well have been true before that; we do not backdate a record past the evidence we have read. Supported, version 5.

This entry is wrong if

A repeat run finds Korean-origin brands invoking a dermatologist on at least half the share US-origin brands do, or finds US-origin brands using clinical-testing language on a larger fraction of storefronts than Korean-origin ones.

Evidence

Tier Bobserved-webn = 4028
orbt: Market Register commerce collector, run commerce-20260805140548
Two different measures on purpose. Dermatologist is pooled by product, because it is a claim made about individual items. Clinical testing is counted by storefront, because Korean brands use it broadly and shallowly and US brands narrowly and deeply, so the pooled share alone (6.1% Korean against 9.2% US) points the opposite way to the number of brands doing it. Both are reported rather than the flattering one. Dermatologist gap holds with Necessaire removed: 3.3% against 1.6%. Retailers are excluded from both origin groups: OLIVE YOUNG Global, Peach & Lily, Soko Glam, Stylevana. Their catalogues are other companies’ product copy, so counting them by the storefront’s own origin would put Korean listings inside the US-origin group. Run commerce-20260805140548.

History

v5correctedAugust 5, 2026
Correction. The retirement recorded above was an operator error, not a finding. The derivation was run against collector run commerce-20260805053004 while that crawl was still in flight and had reached 4 of 66 storefronts, so every claim whose storefronts it had not yet read failed its sample gate and was retired. 44 claims were retired in one command for that reason. The claim was re-derived the same day from collector run commerce-20260805051110, a complete 66 of 66 crawl, and holds. Nothing about the market changed between the two records. The retirement stays in this log because the log is not edited; this entry is what it means. The instrument now refuses to derive from a run missing more than a tenth of the seeded storefronts, and a claim returning from retired now files its own status revision, which is why this correction had to be written by hand rather than appearing on its own.
v4retiredAugust 5, 2026
Retired against collector run commerce-20260805053004: catalogues too thin (KR 2, US 0; need 8 each). The claim held on the sample available when it was written and does not hold on this one.
