Hair follicles are the tiny structures that grow hair in the scalp. Sebaceous glands produce sebum. On areas where acne develops, sebaceous glands surround the hair follicles. The combination of the sebaceous glands and the hair follicles is the pilosebaceous unit, where acne pimples and cysts develop. Sebum moisturizes hair and skin. Each hair pushes up through the skin surface along with sebum. Acne often begins during puberty. It occurs when sebaceous glands in the skin are over-stimulated to produce sebum and skin cells are not shed normally. These sticky cells block the skin's hair follicles, trapping the sebum. The blocked, oil-filled follicle then causes the bacteria normally in the hair follicles to multiply.
