Detailed explanation-1: -Regulation. A complex mixture of fatty acids that keeps the skin soft, supple and pliable is called: Sebum.
Detailed explanation-2: -Human sebum consists of squalene, esters of glycerol, wax and cholesterol, as well as free cholesterol and fatty acids (Table 1). Triglycerides and fatty acids, taken together, account for the predominant proportion (57.5%), followed by wax esters (26%) and squalene (12%).
Detailed explanation-3: -The sebaceous glands, each attached to a hair follicle, produce sebum through a process called holocrine secretion.
Detailed explanation-4: -Sebum lubricates the skin to protect against friction and makes it more impervious to moisture. Furthermore, the sebaceous gland transports antioxidants in and on the skin and exhibits a natural light protective activity. It possesses an innate antibacterial activity and has a pro-and anti-inflammatory function.
