An adolescent has acne with lesions on the cheeks and under the chin. Which distribution is this?

• A. Athletic
• B. Frictional
• C. Hormonal
• D. Pomadal

Answer: (C)

During adolescence, rising androgens drive sebaceous gland activity, increasing oil production in areas with many oil glands. This hormonal influence often manifests as acne on the lower face, especially the chin and jawline, and can involve the cheeks as well. So lesions on the cheeks and under the chin fit the hormonal distribution pattern, since the lower face is a common site for hormone-driven acne in teens. Frictional acne would hit areas from rubbing or occlusion, athletic patterns relate to sweat-prone regions, and pomadal isn’t a standard distribution pattern.
