The primary function of sebaceous glands is to secrete oil, or sebum, which helps to lubricate the skin and hair. Sebum plays a crucial role in maintaining skin hydration, protecting against moisture loss, and providing a barrier against certain types of bacteria and fungi. This oil helps to keep the skin soft and supple, preventing dryness and potential irritation. As the skin and hair are exposed to external elements, the lubrication provided by sebum is essential for overall skin health and functionality.

In understanding this function, it becomes clear that the role of sebaceous glands differs fundamentally from that of sweat glands, which focus on temperature regulation through sweat production. Additionally, while nutrient absorption is critical for overall health, sebaceous glands do not serve this function. Instead, their oil secretion contributes to the skin’s protective barrier, highlighting the unique and vital role they play in skin care and maintenance.
