Honor Society of Nursing (STTI) answeredSebaceous glands produce an oil called sebum, which is thought to play a role in keeping your skin moist. Sebaceous glands are located next to individual hairs in sebaceous follicles. The hormones that cause body changes at puberty also cause the sebaceous glands to produce more oil. If this oil mixes with dead skin cells and blocks a pore, it can produce a pimple.
