State two function of the sebum?

To moisturize the skin, not sure about another function. Sorry =)State two function of the sebum?
way too expensive for what you get. rooms are very small like a motel 6, the staff seems like they have better things to do in the back room rather, than tend to the front counter. one lady was particularly rude. dogs running around the office barking. mediocre breakfast. one thing good about this hotel is that the keys always worked. will not return.State two function of the sebum?
Sebum acts to protect and waterproof hair and skin, and keep them from becoming dry, brittle, and cracked. It can also inhibit the growth of microorganisms on skin. This is what makes the face oily.
