sebum
Pore-clogging oil secretion
Sebum is the oily, waxy substance secreted by sebaceous glands in the skin.
It serves to lubricate and waterproof the skin and hair, preventing them from drying out.
When sebaceous glands produce too much sebum, it can clog pores and contribute to acne; too little leaves skin dry and prone to irritation.
Teenagers often struggle with excess sebum production during puberty.
