Hand sanitizers use antibacterial ingredients like alcohol to kill germs on contact. They are available in the form of gel, foam, and single-use towelettes. Hand sanitizer is a great product to keep in your purse or pocket for times when soap and water are not available. Some hand sanitizers also contain aloe or vitamin E to help keep skin moisturized. Express Medical Supply offers several brands of hand sanitizer, including Purell, Sani-Hands, and more.
