# Cosmetic Affairs > An independent journal exploring cosmetic science, ingredients, and the craft of manufacturing. Cosmetic Affairs publishes cosmetic science explainers, ingredient articles, manufacturing notes, news, and regulatory source briefings. Publication credit identifies responsibility for an article; it does not imply independent scientific review. Regulatory briefings retain their jurisdiction, document status, original source dates, and source-check dates. Consult the linked original documents for their current status. This index and the Markdown exports are generated from published content at build time. Each export identifies its canonical HTML page, author, dates, and any paid-story sponsor. Separately inserted sponsored resources are not part of the article text. ## Publication - [A closer look at cosmetics.](https://cosmeticaffairs.com/about/index.md): Cosmetic Affairs is a journal for people who want to understand what goes into a product, and what happens before it reaches the shelf. - [Sources, review, and corrections.](https://cosmeticaffairs.com/editorial-policy/index.md): How Cosmetic Affairs handles source material, editorial interpretation, updates, and corrections. - [Transparency, AI, and our values.](https://cosmeticaffairs.com/transparency/index.md): Human-written articles, AI-assisted editing, clearly labeled imagery, guest contributions, and the principles behind Cosmetic Affairs. - [Cosmetic Affairs Editorial](https://cosmeticaffairs.com/authors/editorial/index.md): The publication credit used for Cosmetic Affairs explainers, editorial notes, and source briefings. ## Collections - [All stories](https://cosmeticaffairs.com/articles/): The latest from our journals, news desk, and regulatory coverage.
