Sebum is an oily substance secreted by the sebaceous glands in mammalian skin. Its main purpose is to make the skin and hair waterproof and to protect them from drying out. An excess of sebum, however, can make the skin or hair oily, and it can begin to smell when broken down by bacteria outside the body. The sebaceous glands are usually attached to hair follicles, but they also exist in some hairless areas of the human body, such as the eyelids, where they add sebum to tears to keep the eye moist.
