An analysis, not a lab test

Our scores rest on an analysis of what brands publish (website, product pages, formulas, prices, delivery and return terms) and on the experiences their customers share in public reviews.

From analysis to score, in 4 steps

1. 1Collection: what the brand publishes and its customers' reviews.
2. 2Scoring: each criterion of the category gets a score from 0 to 10.
3. 3Overall score: the mean of the criterion scores, out of 10.
4. 4Ranking: the brands of a category are sorted by overall score.
