What are the 3 main roles of sebum in the skin?

according to http://www.acnesource.org/facts_what-cau鈥?/a> these are some functions of sebum:





'; * It reduces water loss from the skin surface


* It protects the skin from infection by bacteria and fungi


* It contributes to body odor


* It is colonized by the bacteria Priopionibacterium acnes, which may have a role in immune regulation ';





A wikibook on the human physiology of the integumentary system mentions these functions:


';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.';
