Sebum is the oily secretion in the skin which keeps the hair and skin moisturized and prevents them from cracking, getting dry, and becoming brittle. Sebum comes from the Latin word "fat".
Sebum is composed of lipids,wax and clusters of dead-fat producing cells.
its is produced in the sebaceous gland and secretes through a small duct that moves up the hair shaft and ultimately rises to the skin's surface, which equals pimples/blemishes.
