What is the common term for closed comedones?

Blackheads
Inflammation
Milia
Whiteheads

The correct answer is: Blackheads

Closed comedones are commonly known as whiteheads. Whiteheads are non-inflamed clogged pores that have a small white or flesh-colored bump on the skin's surface. Blackheads, on the other hand, are open comedones with a dark appearance due to oxidation of the trapped debris. Milia are small cysts filled with keratin, and inflammation refers to the body's response to injury or infection.
