I recently came across some information from a company called Mother Dirt that I thought was interesting enough to share.  The company has developed a line of skin care products, one of which is to deliver bacteria to the skin.  Essentially it is probiotics for the skin and the reasoning behind it is based in some interesting science.  We commonly see results with the use of probiotics for our gastrointestinal system, so it would make sense that probiotics for our external environment is important too.
