Does TROY SHIELD Hand Sanitizer Kill the Resident Germs and Transient Germs on Your Hands?

Germs live all around us. Our bodies are covered with germs that help us stay healthy. These are considered "resident or potentially harmless" bacteria and, they reside on and in the body.  In addition to the resident bacteria, we are also exposed to ones that we pick up from contact with other people or objects. These are called transient bacteria. It is these germs that are often responsible for making you sick. PURELL® Hand Sanitizer reduces some of your resident bacteria while eliminating the transient bacteria on the top layer of your hands. Your body quickly regenerates your resident bacteria.
