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."

“I appreciate the effort to use more naturally sourced ingredients, but given the lack of regulated sourcing, processing, and stability of the tallow, as well as the comedogenic properties of using tallow, I would recommend other methods of hydration,” Dr. Maya Thosani, a double board-certified dermatologist, told Allure.

From Salon
