Evidence method

How Mikoyoo verifies a product

We keep identity, formula, package and market observations separate. Evidence can support one field without proving every other field.

01

Collect a bounded source document

Official registries, brand sites, actual packages and monitored retailer listings serve different evidence purposes. Restricted sources such as CPNP are not scraped.

02

Normalize claims without overwriting history

A source observation becomes a dated assertion. A changed name, barcode, ingredient list or package creates a candidate—not a silent replacement.

03

Resolve identity conservatively

Exact GTIN and official SKU evidence is stronger than a similar name. An 880 prefix, K-beauty marketing text or OCR alone never proves Korean ownership or manufacture.

04

Review conflicts before publication

Formula, Responsible Person, barcode and safety-alert conflicts require a human decision. Private submissions and unreviewed staging records remain outside the public catalog.

Field-level language

What the evidence labels mean

  • Verified

    Reviewed evidence supports the published field.

  • Corroborated

    Two or more sufficiently independent sources agree.

  • Observed

    Seen in a monitored source, without independent confirmation.

  • Unverified

    Reported by a source but not yet confirmed.

  • Conflicting evidence

    Current evidence disagrees and remains under review.

  • Stale

    The latest observation is older than the monitoring threshold.

Market language

“Not observed” is not “not sold.”

A local market listing is a storefront intended for that country. A cross-border listing means a retailer in another market may ship there. We do not present the two as equivalent.

Coverage reports only sources monitored by Mikoyoo. Limited coverage is always shown, and an absent listing is never converted into a claim that the product is unavailable.

Safety and ingredients

Matching requires identifiers.

Safety alerts are published against a product only after strong product identifiers are confirmed. Brand and name similarity alone creates a review candidate, not a public warning.

A declared ingredient list can show additions, removals or reordered text. It cannot on its own prove the underlying formula is identical.
