What is a common feature of acne vulgaris?

• A. Open and closed comedones
• B. Excessive dryness and peeling
• C. Inflammatory nodules only
• D. Redness and irritation with no lesions

Answer: (A)

Open and closed comedones are indeed a hallmark of acne vulgaris. Comedones are hair follicles that become clogged with oil (sebum) and dead skin cells, leading to the formation of blackheads (open comedones) or whiteheads (closed comedones). This characteristic is fundamental to identifying acne vulgaris, as the presence of these lesions initially indicates the development of acne before it progresses to more inflamed forms. Other features of acne may include inflammatory lesions, such as papules or pustules, but the presence of comedones is what specifically defines acne vulgaris in its early stages. Recognizing these lesions helps in the diagnosis and assessment of the severity of acne, guiding appropriate treatment options. Understanding this aid students in focusing on the primary characteristics that define different types of skin disorders, particularly acne vulgaris.
