Clinical studies demonstrated that continued exposure to copper oxide-embedded textiles, such as pillowcases, significantly reduces the depth of facial wrinkles and skin sagging and enhances skin elasticity.
This study substantiated the anti‐aging effect that copper ions have on the skin and gave insights into the mechanisms by which exposure of the skin to copper ions improves the skin well‐being.
