Useful guidance should show its work.
K-Beauty Ledger uses a repeatable review process, clear research labels, and corrections that stay visible.
The five-pass review.
We move from the product’s own claims to the wider context, then finish with a decision written for a specific user—not an imaginary “everyone.”
- 01 / DefineCapture the exact product, market, formula version, price context, and claims under review.
- 02 / DeconstructMap key ingredients, delivery format, packaging, texture signals, and claim-relevant limitations.
- 03 / CompareLook for recurring consumer experiences across eligible sources, skin types, and environments.
- 04 / CheckCompare material claims with relevant human research, reviews, and authoritative references.
- 05 / DecideState the verdict, best fit, trade-offs, unknowns, and what could change the conclusion.
Labels are part of the evidence.
The label at the top of a report tells you how close we were to the product and what kind of inference is reasonable.
Experience with context.
We state who used it, for how long, under what conditions, and what one person cannot establish.
Patterns, not personal claims.
We group repeated public consumer experiences and flag selection, platform, and authenticity limits.
Research, not diagnosis.
We assess claims against the strength and relevance of available evidence.
Our source hierarchy.
Not every source answers the same question. We use each for the job it can reasonably do.
Primary product sources
Official ingredient lists, packaging, instructions, notices, and market-specific brand pages.
High-trust evidence
Peer-reviewed human research, systematic reviews, regulators, and professional guidance where relevant.
Consumer patterns
Eligible public reviews used to identify repeated texture, wear, packaging, and tolerance signals—not to prove causation.
