What is the role of the sebaceous glands?

The sebaceous glands play a crucial role in maintaining healthy skin through the production of sebum, an oily substance that helps to hydrate the skin. Sebum acts as a natural moisturizer, preventing dryness and keeping the skin supple. It also has protective properties, forming a barrier that can help prevent the entry of harmful microorganisms and pollutants. This hydration is essential for maintaining the skin’s integrity and overall appearance, making the role of sebaceous glands vital in skincare and dermatology.

The other options do not accurately describe the primary function of sebaceous glands. While the regulation of body temperature is a function primarily associated with sweat glands, touch sensations are detected by specialized nerve endings in the skin rather than sebaceous glands. Similarly, while sebaceous glands contribute to overall skin health, they are not directly involved in the healing process in the way some other cells and structures of the skin are.
