Sebum is the substance produced by the sebaceous gland that is essential for lubricating the skin. This oily secretion plays a critical role in maintaining the skin's hydration and barrier function. Sebum coats the surface of the skin and hair, preventing water loss and providing a natural protection against external elements, such as bacteria and environmental stressors.

In addition, sebum contributes to the overall health and integrity of the skin by helping to keep it supple and preventing dryness and cracking. The balance of sebum production is crucial; insufficient sebum can lead to dry skin conditions, while excessive sebum may cause issues such as acne.

Understanding the role of sebum emphasizes the importance of maintaining proper skin health and the function of the sebaceous glands within the integumentary system.
