Conventional sanitizers evaporate from your hands in approximately 30 seconds leaving you unprotected. So you end up using sanitizers 15-20 times a day, which is tedious and dries out your skin, leaving it rough. Just Human 24 Hour Protection Sanitizer only needs to be used once a day for 24 hour protection. It has no harsh chemicals, is safe for kids, and it contains moisturizing elements that keep your skin soft.
