Never. Brands can’t pay for placement, preview a verdict or request edits, and we accept no free products in exchange for coverage.
Reader-supported affiliate links, which are always clearly labeled and kept separate from scores.
Four layers: the full ingredient list, published research on key actives, the design and size of brand-reported studies, and patterns across verified buyer reviews. Brand claims are always labeled as brand-reported.
Our verdicts are research-based: we analyze formulas and evidence rather than running our own clinical trials. Whenever we cite a result, we say whose study it is.
Yes. If a brand reformulates, we re-evaluate and publish the new score with a dated changelog on the review.
