What is one of the primary benefits of sebaceous gland secretion?

Sebaceous glands secrete an oily substance called sebum, which plays a crucial role in maintaining skin health. One of the primary benefits of this secretion is its ability to prevent dryness. Sebum coats the skin and hair, providing a protective layer that helps retain moisture, keeping the skin hydrated and supple. This barrier is essential for preventing the skin from becoming dry, flaky, and irritated.

The maintenance of skin moisture is vital for overall skin health, as it helps to protect against environmental factors and supports the skin's natural barrier function. In addition, the lubricating properties of sebum contribute to maintaining the integrity of the skin surface, promoting overall skin vitality and appearance.
