Infected hair follicle in acne, illustration. The sequence progresses from a normal hair follicle at top left. After the follicle has been damaged or blocked (top right), pus and secretions from the sebaceous gland fills the lesion (centre left). This progresses at centre right, culminating in the severe inflammation and swelling at bottom left. Acne is a skin disorder in which the sebaceous glands of the skin become inflamed. It usually occurs in adolescence but can continue through adulthood in severe cases. | |
