How We Rate Ingredients
Comedogenic Scale (0–5)
The comedogenic rating system measures an ingredient's likelihood of clogging pores, based on published dermatological research. 0 means non-comedogenic (will not clog pores), while 5 means highly comedogenic (very likely to cause breakouts).
Fungal Acne (Malassezia)
Certain ingredients feed the Malassezia yeast that causes fungal acne (pityrosporum folliculitis). We flag esters, fatty acids, and oils with carbon chain lengths of C11–C24 that are known triggers, based on research by dermatologists and the fungal acne community.
Data Integrity
Our comedogenic and irritancy ratings draw from peer-reviewed dermatological research, including the widely cited Fulton comedogenicity scale and the Draelos irritancy index, cross-referenced with the EWG Skin Deep database and the European Commission's CosIng ingredient directory. Ratings are reviewed and updated regularly to reflect current scientific consensus.
