artiteacher Sweat and sebum work together to create an acidic barrier that keeps skin hydrated and germ-free.

artiteacher Millions of specialized sensory receptors in the dermis translate physical contact into electrical brain signals.
Acid mantle: Your skin is naturally acidic, with a pH similar to coffee, which helps stop harmful bacteria from growing.
The community of microorganisms, such as bacteria, fungi, and viruses, that inhabit a particular environment. In 2007, researchers began mapping these diverse microbial communities living across different areas of human skin.
