Anatomical terminology |
The sebaceous glands are microscopic (tiny) glands in the skin which produce an oily/waxy substance, called sebum, to lubricate (oil) the skin and hair.[1] In people, these glands are found in greatest amounts on the face and scalp, joined near the top inside hair follicles or sweat pores. However, they are in all skin areas except the palms and soles (undersides) of the feet.[2] There are different kinds of these glands and sebum. In the eyelids, meibomian sebaceous glands emit a special kind of sebum into tears. There are several related medical conditions, including: acne, sebaceous cysts, hyperplasia, sebaceous adenoma and sebaceous gland carcinoma (see section below: Diseases). Washing skin or hair with plain detergent can cut the amount of sebum in oily skin. Also, water temperature over 84 °F (29 °C) can keep sebum melted during a wash.
