Learning about the new understanding of the skin microbiome over the past few years, I was reassured that it's a pretty brillant product of millions of years of evolution, a superorganism composed of trillions of other organismes that were doing fine before we came along and will do fine after we are gone. The ecosystem does not need to be maintained in any elaborate way that we didn't already know made our skin look good: sleeping ans eating well, minimizing anxiety, and spending time in nature.
