Does skin keep out germs

Yes, skin acts as a primary barrier that helps keep out germs and pathogens. The outer layer of skin, called the epidermis, is made up of tightly packed cells that prevent many harmful microorganisms from entering the body. Additionally, skin produces natural oils and antimicrobial peptides that further protect against infection. However, cuts, abrasions, or other injuries can compromise this barrier, making it easier for germs to enter.
