This secretion is not merely a surface-level moisturizer; it is a dynamic fluid that transports antioxidants and antibacterial compounds to the stratum corneum, the outermost layer of the epidermis. These glands synthesize and secrete sebum, a mixture of triglycerides, wax esters, squalene, and cholesterol.

The wax esters and squalene provide oxidative stability, preventing the oil from becoming rancid quickly. The Science of Sebum Composition Sebum’s effectiveness is dictated by its molecular composition.
Sebaceous glands are connected to hair follicles and are most abundant on the face, scalp, and upper back. The Protective Barrier and Moisture Retention One of the primary roles of skin oil is to form the outermost layer of the permeability barrier.
