This tool checks whether a skincare or makeup product may clog your pores. “Comedogenic” means an ingredient is more likely to block pores and lead to blackheads or breakouts. We score each product from 0 to 5: 0 is unlikely to clog pores, 1–2 is low risk for most people, 3 is moderate, and 4–5 is high risk if your skin breaks out easily.

This tool is for general guidance only. It is not medical advice, and it cannot replace a dermatologist or patch testing.
