In the context of acne, what does the term "comedones" refer to?

The term "comedones" specifically refers to clogged hair follicles or pores, which are a fundamental characteristic of acne. These clogged pores form when sebum (oil), dead skin cells, and sometimes bacteria accumulate in the hair follicle. There are two types of comedones: open comedones, commonly known as blackheads, and closed comedones, or whiteheads.

Understanding that comedones are the precursor to more severe acne forms, including inflamed lesions, is crucial for effective acne treatment. Treatments often focus on addressing and preventing comedone formation, thus reducing the likelihood of developing more serious acne conditions. The other options relate to different aspects of acne but do not accurately define comedones. Inflamed lesions are manifestations of acne but are not the same as clogged pores. Scars are the result of acne lesions healing and do not represent the original comedonal formation. Symptoms of infection may occur in severe cases but don’t encapsulate what comedones are.
