What is the epidermis?

Less than a millimeter thick, the epidermis serves as your body's protective coat, keeping potential toxins out. It's where some molecules are created (like vitamin D3, from the sun) and others are destroyed (like folic acid, from the same sun). This layer of skin is continually renewing itself; beginning at birth, old skin cells die off and are replaced by new ones.
