Sebum Production

Meaning

The physiological process by which the sebaceous glands, which are microscopic exocrine glands in the skin, synthesize and secrete an oily, waxy substance called sebum. Sebum is a complex mixture of triglycerides, wax esters, and squalene that functions to lubricate and waterproof the skin and hair. This production is heavily regulated by androgens, making it a direct clinical marker of sex hormone activity.
