(HealthDay News) -- Acne is often thought of as a younger person's condition -- a symptom of the transition from childhood to young adulthood.
But some people in their 30s, 40s and 50s still have acne, the American Academy of Dermatology says.
Here's the group's list of common triggers of adult acne:
- Fluctuating hormone levels during the menstrual period, during pregnancy, peri-menopause and menopause, and after starting or discontinuing birth control.
- Stress. Our bodies produce more androgens when they're under stress. Androgens stimulate oil glands and hair follicles.
- Family history of adult acne.
- Side effect of some hair- and skin-care products.
- Side effect of certain medications.
