Which structure is primarily involved in skin's waterproofing and lubrication through sebum?

Explanation:
Sebaceous glands are responsible for producing sebum, the oily substance that coats the skin and hair. This lipid film forms a water-resistant barrier, helping to limit water loss and keep the skin lubricated. The sebum is released into the hair follicle canal and then onto the skin surface, which is why these glands are closely linked to hair follicles. Eccrine glands produce sweat for cooling rather than lubrication, and dermal papilla supports hair growth and nourishment rather than sebum production. Therefore, the structure primarily involved in waterproofing and lubrication through sebum is the sebaceous glands.
