Start with the question
If you want the current product formula, start with the product label or brand page. If you want naming and function context, use ingredient databases. If you need limits or restrictions, go to regulatory sources.
| Question | Useful source | Limit |
|---|---|---|
| What is in this product? | Current package or brand page | May differ by region or batch |
| What is the ingredient name? | INCI and ingredient databases | Name does not equal suitability |
| Is there a restriction? | Regulatory text and official lists | Conditions and product category matter |
| Will it suit me? | Your history plus product context | Not fully predictable from the label |
Official sources are best for boundaries
Official sources are strongest when the question is about registration, labeling, restrictions, or allowed use. They are less useful for predicting whether a specific serum will feel good on your skin.
Best for the exact product version in your hand. Check region, size, batch, and reformulation date when available.
Best for restrictions, labeling obligations, allowed uses, and regulatory status. Read conditions, region, and product category.
Best for names, synonyms, and common cosmetic functions. Do not treat a function field as a product promise.
Useful when it cites sources and separates regulation, formula role, and personal preference.
- European Commission CosIng
- FDA cosmetic ingredients overview
- FDA cosmetics labeling
- Health Canada Cosmetic Ingredient Hotlist
Third-party sites need citations
Plain-language explanations are useful when they keep their source trail visible. Prefer pages that separate regulatory boundaries, formula function, and personal preference.
Keep version differences in mind
Formulas can change by market, batch, product size, or reformulation. When buying, check the current label for the exact product version.
