MCQ IN MEDICINE

Detailed explanation-1: -Why do I still have acne in my late 20s? At its root, adult acne is caused by the same things that cause teen acne: excess skin oil and bacteria. Any changes in hormones, including those brought on by pregnancy and menstruation, can trigger excess oil. Women who smoke also seem to be more prone to acne.

Detailed explanation-2: -No one knows exactly how long acne will last for each person. Many teens find that their acne improves as they get older and that it almost disappears by the time they reach their twenties. Others have acne well into their adult years.
