Detailed explanation-1: -The normal function of sebaceous glands is to produce and secrete sebum, a group of complex oils including triglycerides and fatty acid breakdown products, wax esters, squalene, cholesterol esters and cholesterol. Sebum lubricates the skin to protect against friction and makes it more impervious to moisture.
Detailed explanation-2: -The main cause of an overproduction of sebum is hormonal imbalances, including as a result of puberty and pregnancy. “As well as hormones, heat, exercise and genetics play a part, ‘’ says Kate Kerr, acclaimed clinical facialist.
Detailed explanation-3: -WHAT DOES SEBUM DO? Put simply, it helps to protect your scalp and hair, to keep them healthy and feeling moisturized. Sebum forms a kind of barrier on the surface of the skin to protect it from the elements, and oxidative damage (the same harmful force that causes skin aging).
