Quizplus · Accepted Answer

The oil on the surface of the skin is made up of sebum, which is a mixture of fatty acids, wax esters, and other lipids produced by the sebaceous glands. It is not waste material or extracellular fluid. Although plasma leakage can contribute to skin exudate in the case of injury or inflammation, it is not the primary component of normal skin oil.
