Which term describes clogged pores that result in a lesion?

The term that describes clogged pores resulting in a lesion is comedone. Comedones are a type of acne lesion that occurs when hair follicles become clogged with sebum (oil), dead skin cells, and bacteria. When these clogged pores remain closed, they can result in whiteheads; when they are open and exposed to air, they oxidize and form blackheads. The term "comedone" encapsulates these conditions collectively.

While blackheads and whiteheads refer specifically to the open and closed forms of comedones, respectively, the broader term "comedone" encompasses both types as lesions produced by clogged pores. Papules, in contrast, are inflamed lesions that arise from the irritation and infection of these clogged pores but do not directly describe the clogged pore condition. Understanding these definitions helps clarify the terminology used in skincare and acne treatment.
