What Are Copper Peptides and How Do They Interact with the Skin?

Copper peptides are naturally occurring complexes in the body. When used in topical applications, they are often celebrated for their role in skin maintenance. However, it is a misconception that these ingredients have no effect on the skin; on the contrary, they are biologically active.
