These areas of skin have the most oil (sebaceous) glands. Acne occurs when hair follicles become plugged with oil and dead skin cells. Hair follicles are connected to oil glands. These glands secrete an oily substance (sebum) to lubricate your hair and skin.
Acne happens when oil (sebaceous) glands come to life around puberty, when these glands are stimulated by male hormones that are produced in the adrenal glands of both boys and girls. The oil glands, which are located just beneath the skin, continuously produce and secrete oil through openings in the skin.
