How this is paid for, and how it stays honest.

Some "Where to buy" links are affiliate links. If you buy through one, we may earn a small commission at no extra cost to you. That is currently how the site is funded.

• Affiliate links are labelled wherever they appear.
• Commission never influences a verdict, a score, a ranking or whether a product is listed. Ratings are computed from the formula and community reports before any retailer link exists.
• Products without any affiliate link are rated on exactly the same basis, and can and do outrank products that carry one.
• Prices shown come from the retailer and may be out of date at the time you click.

We don't accept sponsorships, paid placements, paid reviews, or gifted products in exchange for coverage. No brand can pay to be added, removed, re-scored or featured. If that ever changes, this page changes first and any paid content will be labelled as such.

Our method — what we read, what we score, and how confident we are — is written up in how we know this. Corrections are welcome from anyone, brands included: corrections@skinparency.com.

We use automated tools, including AI models, to read ingredient lists off pack photos and brand pages, to normalise ingredient spellings, and to summarise published evidence. Scores and verdicts themselves are produced by deterministic rules we wrote — not by an AI deciding what it thinks of a product.

AI extraction can be wrong. That's why every product shows where its ingredient list came from and how many independent sources agree, and why single-source lists are labelled as such rather than treated as fact.

Community numbers are aggregates of what real users reported after using a product. They are self-reported, unverified, and often based on small samples — we show the sample size so you can judge them. Individual users' entries are never shown to other users.
