What substance do sebaceous glands produce?

Sweat
Melanin
Sebum
Keratin

The correct answer is: Sebum

Sebaceous glands are glands in your skin that produce an oily substance called sebum. This sebum is important for keeping your skin moisturized and healthy. The other options listed, sweat, melanin, and keratin, are all substances that are produced by other glands or cells in the body and do not come from sebaceous glands. Sweat is produced by sweat glands, melanin is produced by melanocytes in the skin, and keratin is a protein produced by cells in the epidermis. Therefore, only sebum is the correct substance produced by sebaceous glands.
