Treat your face to our Zinc infused pillowcases. We use the same Zinc technology found in our bedsheets for our pillowcases. Sleeping on a clean pillowcase has many benefits for your skin. Modern Zinc makes that easy with our antibacterial, Zinc infused pillowcase. We use a sateen woven 400 thread count fabric for our pillowcases. They are produced from high-quality long staple cotton.
