What is the function of sebaceous glands?

Sebaceous glands play a crucial role in maintaining skin health by producing an oily substance known as sebum. This oily secretion helps lubricate the skin and hair, preventing dryness and reducing the likelihood of skin irritation or damage. The sebum forms a protective barrier on the skin, which not only aids in moisturizing but also has antimicrobial properties, helping to protect against bacteria and other pathogens that can penetrate the skin. The presence of sebum is essential for maintaining the integrity and elasticity of the skin, contributing to overall skin health.

While other glands and structures in the integumentary system have distinct functions—such as sweat glands for temperature regulation, melanocytes for pigmentation, and hair follicles for hair growth—sebaceous glands specifically focus on oil production, highlighting their essential role in skin lubrication and protection.
