What are closed comedones commonly referred to as?

Closed comedones are commonly referred to as whiteheads. They are small, flesh-colored or white bumps that appear on the skin and are typically caused by a buildup of oil, dead skin cells, and bacteria that clog hair follicles. Unlike blackheads, which are open comedones that are exposed to air and oxidize, causing the dark appearance, whiteheads are sealed at the surface and remain closed. This closure prevents oxidation and gives them their characteristic white or skin-colored appearance. Understanding this distinction is crucial for effective skin care and treatment strategies targeting acne and other related conditions.
