Not all bacteria are bad for you. In fact, killing all bacteria may do more harm than good. Our Tom’s of Maine Prebiotic Natural Liquid Hand Soap, with the prebiotic ingredient inulin, helps promote the growth of good bacteria. The sulfate-free**, dermatologist tested formula has a microbiome-friendly pH and retains skin's natural moisture while helping to maintain a healthy skin barrier. At Tom's of Maine, we use only ingredients that meet our Stewardship standards for natural, sustainable, and responsible ingredients to help empower families to live more naturally.
