What are comedones?

Comedones are a specific type of skin lesion that occurs when hair follicles become clogged with sebum, dead skin cells, and other debris. This clogging can lead to the development of acne. Comedones can be classified into two categories: open comedones, commonly known as blackheads, and closed comedones, which are referred to as whiteheads. The formation of comedones is an important step in the pathogenesis of acne vulgaris, and managing them is crucial in the treatment and prevention of more severe acne forms. Recognizing comedones as clogged hair follicles highlights their role in acne development and underscores their significance in skincare routines and treatments aimed at acne control.
