What is another name for a closed comedo?

A closed comedo is commonly referred to as a whitehead. This term describes a type of acne where the hair follicle is completely blocked by sebum and dead skin cells, preventing the contents from being exposed to air. Because of this, the surface of the comedo remains closed, leading to the characteristic white appearance.

In contrast, a blackhead, which is often confused with a closed comedo, is actually an open comedo where the pore remains open to air, causing the trapped material to oxidize and turn dark. Understanding the differences between these terms is crucial for identifying various forms of acne and effectively treating them.

Other terms, such as "pore," refer to the openings on the surface of the skin and are not specific to the type of comedo. "Acne" is a broader term that encompasses various lesions, including both blackheads and whiteheads, rather than specifically indicating closed comedones. Thus, the terminology around closed comedones is important in the context of skin care and treatment.
