What is the main product produced by sebaceous glands?

• A. Sweat
• B. Oil
• C. Hormones
• D. Collagen

Answer: (B)

Sebaceous glands are specialized structures located within the skin that primarily produce an oily substance known as sebum. Sebum serves several important functions: it provides lubrication to the skin and hair, helps maintain moisture levels, and offers a degree of protection against bacterial growth. The oiliness of sebum helps to prevent the skin from drying out and contributes to the overall health and integrity of the skin barrier.

While sweat is produced by sweat glands, hormones are produced by various endocrine glands in the body, and collagen is a structural protein synthesized primarily by fibroblasts in the dermis. These substances have distinct roles and are not the products of sebaceous glands. The main merchandise of sebaceous glands, specifically the oil, is key to maintaining skin health and preventing conditions such as acne when these glands become overactive or blocked.
