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.
Put simply, acne is a disorder of the turnover of skin cells, called keratinization. Improper skin turnover leads to retained cells, which block the oil glands and pores and trap protein and sebum (your skinâs natural oil) under the skin. Those proteins and oils become food for P. acnes, the bacteria that cause acne.
