Read the evidence behind the graph.

What a product connection means

A product-to-ingredient edge means the ingredient was mapped from an available product list. We record list position where possible. Position is not an exact concentration, and “key ingredient” is a discovery marker rather than a measured percentage.

Formulas may differ by market or change over time. Reformulated and discontinued states are kept visible so an old record is not presented as a current buying recommendation.

What an interaction connection means

Ingredient-to-ingredient edges summarize conservative layering context for separate products. They do not mean that a finished formula containing both ingredients is unsafe. Each note has a confidence level. Database candidates are excluded from the public graph until a source is checked for direct relevance and the public note is narrowed to what that source actually tested.

• Synergistic: evidence or established formula context supports a complementary role.
• Caution: timing, frequency, tolerance, or combined irritation deserves attention.
• Avoid: reserved for the strongest conservative guidance and requires clear evidence.

What “formula companion” means

Formula companions are ingredients that co-occur in mapped active products. Co-occurrence is descriptive. It is not proof of synergy, compatibility, safety, efficacy, or recommended layering.

Editorial and commerce separation

Phase-one K-Beauty Atlas uses text-only editorial references and does not reproduce brand logos or product photography. Brand and product names identify the records being discussed; they do not imply endorsement, sponsorship, or collaboration. Amazon affiliate availability does not determine graph inclusion, confidence, article conclusions, or product status. Amazon links are labeled paid links, and current regional labels and sellers should be checked before purchase.

Accuracy, effects, and adverse reactions

K-Beauty Atlas is an informational research tool, not medical advice, diagnosis, treatment, or an individual safety assessment. We review records before publication, but data may still be incomplete, outdated, or inaccurate. Ingredient descriptions, concern tags, interactions, graph proximity, co-occurrence, and article summaries are general editorial context. They do not establish the clinical efficacy of a finished product or predict its benefits, compatibility, allergies, irritation, or other adverse reactions for any person.

We do not guarantee that a product is safe, suitable, effective, compatible, allergen-free, or free of adverse effects. Individual responses vary, and formulas and directions may differ by market or change without notice. Verify the current package label, ingredient list, warnings, and directions before use. If a reaction occurs, stop using the product and contact a qualified healthcare professional; seek urgent medical help for severe or rapidly worsening symptoms.
