Comedogenic Ingredients
Comedogenic ingredients are substances that have a tendency to clog pores (comedones), which can lead to blackheads, whiteheads, and acne breakouts. Each ingredient is rated on the comedogenic scale from 0 (non-comedogenic) to 5 (highly comedogenic). Ingredients with a score of 3 or higher are generally considered risky for acne-prone or oily skin types.
Below you will find 40 ingredients in our database flagged as medium or high pore-clogging risk, ordered by their comedogenic score.
High Pore-Clogging Risk (13)
