The largest organ in your body is your skin. What goes on outside is equally important as what happens inside. Your good health and your skin’s health are inexorably linked. On a practical level, we know that! Just eat or drink from something you know you shouldn’t and your skin shows up the next day and screams at you like some kind of deranged witch with a pimple for the middle of your forehead! Good, healthy skin is home to a vast number of microbes named collectively, the skin microbiome. Scientists tell us to think of this in the same way as gut health.
