What does "sebum" refer to?

A type of acne
An oily substance produced by sebaceous glands
A skin treatment method
A form of sunlight exposure

The correct answer is: An oily substance produced by sebaceous glands

Sebum is specifically recognized as an oily substance that is secreted by sebaceous glands located in the skin. These glands play a critical role in maintaining healthy skin by providing necessary moisture and lubrication. Sebum helps to form a protective barrier, preventing the skin from drying out and also serving as an antibacterial agent. Furthermore, understanding sebum is essential for professionals in cosmetic arts, as an imbalance in sebum production can lead to various skin conditions, including acne or excessively dry skin. This biological function underlines the importance of maintaining a healthy level of sebum for overall skin health and appearance.
