Comedogenic
Comedogenic — a term describing ingredients or products that have a tendency to clog pores, which can contribute to comedones such as blackheads and whiteheads. How comedogenic something is can depend on its concentration, the overall formula, and an individual's skin.
Key points
- Comedogenic ingredients may block pores and encourage the formation of blackheads or whiteheads in prone skin.
- Comedogenicity is often described on a scale, but ratings can be inconsistent and don't always predict real-world results.
- An ingredient's effect depends on its concentration, the finished formulation, and how a person's skin responds.
- People with acne-prone skin sometimes avoid ingredients widely reported as more comedogenic, though tolerance is individual.
Frequently asked
Do comedogenic ingredients always cause breakouts?
Not necessarily, since the effect depends on concentration, the overall formula, and your individual skin. An ingredient rated as comedogenic may still be well tolerated by many people.
How reliable are comedogenic ratings?
Comedogenic scales can be inconsistent because they are often based on limited testing that may not reflect finished products. They are best used as a general guide rather than a definitive prediction.
