Sebaceous Glands: Definition and Explanation

'Sebaceous glands' are small glands found in the skin that produce an oily substance called sebum. Sebum helps to lubricate the skin and hair, keeping them soft and pliable. It also forms a protective barrier against bacteria and other harmful substances. Sebaceous glands are located near hair follicles, and their secretions are released into the hair follicle through a duct. The amount of sebum produced can vary depending on factors such as age, hormones, and genetics. Excessive sebum production can lead to acne, while insufficient sebum production can cause dry skin.
