Acne Vulgaris
Acne Vulgaris ( 39 Questions)
Excessive skin hydration - Excessive skin hydration is not the primary pathogenesis of acne vulgaris. In fact, excessive oil production contributes to the development of acne lesions.
The primary pathogenesis of acne vulgaris involves increased keratinization (abnormal skin cell turnover) and follicular plugging. Excess sebum production, along with dead skin cells and bacteria, can lead to the formation of comedones, which are a hallmark of acne vulgaris.
Overproduction of melanin - Overproduction of melanin is not the primary cause of acne vulgaris. Melanin is responsible for skin pigmentation, but it does not directly contribute to acne formation.
Allergic reaction to environmental allergens - Acne vulgaris is not primarily caused by an allergic reaction to environmental allergens. While allergens can exacerbate skin conditions, they are not the underlying cause of acne vulgaris.
Explanation: The primary pathogenesis of acne vulgaris involves increased keratinization (abnormal skin cell turnover) and follicular plugging. Excess sebum production, along with dead skin cells and bacteria, can lead to the formation of comedones, which are a hallmark of acne vulgaris.
