What does comedogenic mean?

Something that is comedogenic tends to clog facial pores and cause blackheads or acne to form.

 A comedo is a more formal word for a blackhead, most often forming on the face. Something that is comedogenic promotes or accelerates the formation of blackheads. Some substances are known to be comedogenic because they are made from certain types of oils or mild acids that tend to clog pores. If you’re concerned about the number of blackheads you have or might develop, you might be advised to check the ingredients on your makeup and skincare products for common comedogenic ingredients.

Dermatologists and cosmetologists frequently recommend noncomedogenic skincare treatments and cosmetics to help prevent blackheads. As you might guess, the non- in noncomedogenic means “not.” In other words, a noncomedogenic cleanser, lotion, or makeup usually won’t clog your pores.

Example: The lotion I used on my face was pretty thick and turned out to be comedogenic.

Where does comedogenic come from?

The first records of the term comedogenic come from around the 1960s. It combines comedo, a formal term for a blackhead, and the combining form -genic, meaning “producing or causing.” Comedogenic effectively means “causing blackheads.”
