Editorial policy

Research and writing

• We read consumer and professional cosmetic explainers to identify the questions an article needs to answer.
• Ingredient identity is checked against current ingredient databases, regulatory records, or manufacturer documentation.
• Benefit claims are compared with the best available evidence and the conditions under which it was produced.
• Every major benefit must be paired with an ingredient-specific explanation of how it could work and a clear label for the evidence level, such as human, cell, laboratory, or ingredient-function evidence.
• Product listings may help us understand common formats, but they do not decide an article's conclusion.

Review before publication

• The page must answer the reader's main question in its title, summary, and opening rather than burying the ingredient's characteristic benefit.
• Identity, benefit, mechanism, practical use, cautions, and the limits of the cited material are checked as separate items.
• A Korean master is reviewed for natural phrasing before the English version is independently adapted and read again in English.
• Internal process notes, product-demand evidence, unsupported superlatives, and medical-treatment claims are excluded from public copy.
• Publication and review dates, sources, language pairing, links, and page rendering are checked before a page is made public.

Claims and corrections

Articles explain useful cosmetic effects without turning preliminary evidence into a guaranteed result or a medical treatment claim. Material corrections are added to the article, its review date is updated, and changes that alter a reader's understanding are recorded on the public corrections page.

Advertising

Advertising does not determine which ingredients are covered or how a claim is assessed. Ads are labeled and kept separate from the article text.
