How does your skin host a whole world of microbes?
Right now, as you read this, millions of tiny creatures are living on your skin. They're invisible to your eyes, but they're there — bacteria, fungi, and other microscopic beings, going about their lives on the landscape of you.
Your skin isn't smooth like glass. Up close, it's more like a mountain range with valleys, caves, and rivers. The "mountains" are the ridges between your skin cells. The "caves" are your hair follicles. The "rivers" are the oils flowing from tiny glands.
