There are more and more examples of the ways in which we can benefit from our bacteria. According to researcher Rolf Lood from Lund University in Sweden, this is true for the skin as well.
He has shown that the most common bacteria on human skin secrete a protein which protects us from the reactive oxygen species thought to contribute to several skin diseases. The protein has an equally strong effect on dangerous oxygen species as known antioxidants such as vitamin C and vitamin E.
