Editorial protocol / How we work

Useful guidance should show its work.

K-Beauty Ledger uses a repeatable review process, clear research labels, and corrections that stay visible.

Source-awareConflict-disclosedProportional certainty

How we choose products to investigate

We start with a consumer need and a specific Korean retail product. We examine domestic and overseas exposure, formula, disclosed reviews, value and purchase references separately. Being unfamiliar is not sufficient for a recommendation; fit and trade-offs remain essential.

We separate platform totals from inspected reviews and record advertising, product provision, purchase verification and unknown relationships independently. Product discovery leads the publication; ingredient and routine guides support specific decisions.

제품을 먼저 고르는 기준

소비자의 필요와 구체적인 한국 판매 제품에서 시작합니다. 국내외 노출, 처방, 공개 후기, 가격 대비 가치와 구매 경로를 따로 확인합니다. 덜 알려졌다는 이유만으로 추천하지 않으며, 좋은 제품에도 맞는 피부와 사용 조건이 있습니다.

직접 읽은 후기 수와 플랫폼의 전체 후기 수를 구분하고, 광고·제공·구매인증·관계 미확인을 따로 기록합니다. 제품 리포트를 우선하며 성분·루틴 가이드는 실제 선택 질문을 돕도록 연결합니다.

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.

DIRECT USE

Experience with context.

We state who used it, for how long, under what conditions, and what one person cannot establish.

REVIEW SYNTHESIS

Patterns, not personal claims.

We group repeated public consumer experiences and flag selection, platform, and authenticity limits.

EVIDENCE REPORT

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.

PRODUCT FACTS

Primary product sources

Official ingredient lists, packaging, instructions, notices, and market-specific brand pages.

EFFICACY & SAFETY

High-trust evidence

Peer-reviewed human research, systematic reviews, regulators, and professional guidance where relevant.

LIVED EXPERIENCE

Consumer patterns

Eligible public reviews used to identify repeated texture, wear, packaging, and tolerance signals—not to prove causation.

What every Product Report must show.모든 제품 리포트에 공개하는 것.

Independence is demonstrated with a traceable audit trail—not a trust-us slogan.독립성은 “믿어 달라”는 문구가 아니라 독자가 다시 확인할 수 있는 분석 기록으로 증명합니다.

01 / IDENTITY & RELATIONSHIPS

The exact product and who paid for what정확한 제품과 경제적 관계

SKU, market, formula version, review date, direct-use status, product provision, affiliate links, payment and brand pre-approval are disclosed at the top.SKU·판매국가·처방 버전·검토일·직접 사용 여부와 제품 제공·제휴·금전·브랜드 사전검수 여부를 글 상단에 밝힙니다.

02 / FORMULA MAP

INCI order is a clue, not a lab formula전성분 순서는 단서이지 배합표가 아닙니다

We map humectants, emollients, occlusives, emulsifiers, texture, preservation and highlighted actives. Concentration is labelled only as disclosed, possibly above 1%, possibly at or below 1%, or not quantifiable.보습·유연·밀폐·유화·질감·보존·강조 성분으로 처방 골격을 읽습니다. 함량은 공개 수치, 1% 초과 가능, 1% 이하 가능성, 정량 불가로만 표시합니다.

03 / CLAIM AUDIT

The ad, the test and the nearest independent evidence광고 문구와 시험, 독립 근거를 한 줄씩 대조합니다

For every material claim we record whether the evidence tests the same finished product, sample, comparator, duration, outcome, absolute effect, adverse events, funding and full-report availability.핵심 주장마다 동일 완제품인지, 표본·대조군·기간·지표·절대효과·이상반응·연구비·원문 공개 여부를 확인합니다.

04 / REVIEW SAMPLE LEDGER

Counts, exclusions and commercial context후기 수와 제외 사유, 상업성을 공개합니다

Each platform is reported separately: visible pool, records actually read, included and excluded counts, incentives or sponsorship, unknown relationships, repeated positives, repeated negatives and limitations.플랫폼별 전체 수, 실제로 읽은 수, 포함·제외 수와 사유, 협찬·인센티브·관계 불명, 반복된 장점·단점과 한계를 따로 기록합니다.

Review flow: found n → duplicates removed n → full text checked n → excluded n by reason → non-promotional use-context n / commercial n / relationship unknown n.후기 선별 흐름: 확인 n → 중복 제거 n → 본문 검토 n → 사유별 제외 n → 비광고성·실사용 정황 n / 상업성 n / 관계 불명 n.
No visible sponsorship label does not prove a review is independent. Review counts describe patterns in a self-selected sample; they are not efficacy or adverse-event rates. Each report states who checked review selection and coding. A repeat check by the same editor is not independent verification. Where no second reviewer was involved, the report says so.협찬 표시가 없다는 사실만으로 비협찬을 단정하지 않습니다. 후기 건수는 자기선택 표본 안의 패턴이며 효능·부작용 발생률이 아닙니다. 후기 선별·코딩을 누가 확인했는지 글마다 밝힙니다. 동일 편집자의 재검토는 독립 검증이 아닙니다. 별도 검토자가 참여하지 않았다면 그 한계를 명시합니다.
