What are blackheads?Updated a year ago
Blackheads are disruptive clogs in the skin. Their medical name is “open comedones,” and they’re considered an acne symptom, along with whiteheads and inflammatory pimples.
They’re made up of sebum and dead skin cells that harden and clog up the pore. They can vary widely in size and severity. Unlike pimples, there isn’t redness, pain, or swelling.
They’re called blackheads because they turn dark at the surface where the clog is exposed to oxygen. They’re generally more common in those with oily or acne-prone skin.
