An excited mother of a teenage boy with severe acne furiously reports to the nurse. "I've told him a thousand times he should bathe more often! I've kept after him about all the junk food he eats. I jump on him when I see him squeezing his zits.I tried to get him to scrub his face three times a day! The complaint the nurse recognize as a true statement about the cause of acne is:

A. Poor personal hygiene is incorrect because acne is not caused by dirt or poor hygiene. Excessive washing or harsh cleansing can actually irritate the skin and worsen acne rather than improve it. B. Squeezing the lesions is correct because manipulating or squeezing acne lesions increases inflammation, can push bacteria deeper into the skin, and raises the risk of infection, scarring, and prolonged healing. This behavior can significantly worsen acne severity. C. Ingestion of junk food is incorrect because, although diet is often blamed, no definitive evidence shows that junk food directly causes acne. Some studies suggest certain dietary patterns may influence acne, but it is not a primary cause. D. Need for facial scrubs is incorrect because vigorous scrubbing irritates the skin, increases inflammation, and can exacerbate acne. Gentle cleansing is recommended rather than abrasive scrubs.
