What's in the data

One row per ingredient: name, comedogenic_rating_0_5 (0 = non-comedogenic / acne safe, 5 = highly pore-clogging), category (oil, ester, emulsifier, botanical extract…), pore_clogging (rating ≥ 3), fungal_acne_trigger (can feed Malassezia), aliases (normalized INCI synonyms) and the url of the ingredient's detail page.

Method & sources

Ratings are compiled from published comedogenicity references — primarily Fulton et al. (1984, PMID 6229554) and the re-evaluation by Draelos & DiNardo (2006, PMID 16488305) — plus AAD guidance. A rating reflects an ingredient's potential to clog pores at high concentration, not a verdict on any finished formula. Full methodology on each ingredient page.
