Question: 1 / 400

What is the primary function of sebum on the skin?

Cools the skin

Lubricates the skin

The primary function of sebum on the skin is to lubricate the skin. Sebum, which is an oily substance produced by sebaceous glands, plays a crucial role in maintaining the skin's moisture balance and preventing dryness. This natural oil helps to keep the skin soft and supple, forming a protective barrier that can reduce water loss from the skin's surface.

In addition to lubrication, sebum also has other protective functions. While it does contribute to the overall health of the skin, such as providing some level of antimicrobial properties that can help ward off certain infections, its primary role is to ensure the skin remains lubricated and hydrated. Furthermore, it does not provide significant UV protection, and while it may contribute slightly to cooling through evaporation, this is not its main function.
