small skin gland producing oily sebum for lubrication
A sebaceous gland, also known as an oil gland, is a small gland in the skin that produces sebum, an oily substance that helps to lubricate and protect the skin and hair. These glands are typically found in high concentrations on the face and scalp and are connected to hair follicles, releasing sebum through the hair follicle to the surface of the skin.
