Aloe Vera is an anti-microbial that can kill bacteria, fungi and other microbes. It works by blocking the cell membrane of the microbe, preventing it from multiplying or spreading. When a wound is infected with bacteria or fungus, aloe vera hand wash helps to fight off infection by sealing up any pores in your skin that might allow them to enter your body. This makes it ideal for treating wounds (both minor cuts and burns), as well as helping with skin repair after surgery or illness.
