Which gland produces oil on the face?

• A. Sweat Glands
• B. Ceruminous Glands
• C. Meibomian Glands
• D. Sebaceous Glands

Answer: (D)

Oil on the face is produced by sebaceous glands. These glands secrete sebum, an oily substance that keeps skin and hair moisturized and forms a protective barrier. They’re linked to hair follicles and spread across much of the facial skin, which is why facial skin often feels oily.

Sweat glands, in contrast, release sweat for cooling and do not contribute oil to the skin. Ceruminous glands make earwax in the ear canal, not on the face. Meibomian glands are a type of sebaceous gland located in the eyelids and primarily help lubricate the surface of the eye; they’re specialized and not the general source of facial oil.
