Sebaceous glands produce sebum which is an oily and white substance containing lipids such as triglycerides, wax esters, and squalene. Sebum helps to lubricate and waterproof the skin, but it is not involved in cooling the body. Eccrine sweat glands are active from birth and do not become active at puberty, and they produce a thin and watery secretion consisting of mostly water, electrolytes, and a small amount of organic substances.
