SOAP SAVES LIVES. But did you know that excessive use of soap and skin-care products is harming our health and the environment? Apart from in hand-washing there is no need to use soap on our bodies at all?

In Clean, he takes us on an irreverent and entertaining journey through our complex relationship with our bodies and cleanliness. Drawing on the latest science, he introduces a new way to think about cleanliness - one that is cheaper, simpler and better for our skin, our immunity and the world in which we live.
