Predict why does acne worsen at puberty?
What will be an ideal response?
Sebaceous glands and sebaceous follicles are very sensitive to changes in concentrations of sex hormones. When the concentration of these hormones increases at puberty, the sebaceous glands are stimulated to secrete greater amounts of sebum, which can block sebaceous ducts with accumulated secretions, causing inflammation and providing a fertile environment for bacterial infection.
