Can Satin Pillow Cases Really Prevent Facial Wrinkles?

It has long been held that satin pillowcases can prevent wrinkles, but how true is that?

Satin

Sleeping on satin pillow covers is a luxurious experience. The slippery surface of satin means satin seldom bunches up as cotton does. In turn, that means that you won’t wake in the morning with the imprint of wrinkles on your face.

Imprints

Not having the imprints of wrinkles is not the same as not having wrinkles, so what is the truth?

Copper

It seems that satin has an active copper content. Copper is one of the trace elements that help cells grow. Maybe there is an argument for saying that the constant exposure to copper and the lack of exposure to wrinkle imprints does help to prevent wrinkles.

There have been many case studies that seem to support the theory, so it is probably at least true in part that sleeping on satin pillowcases can help prevent wrinkles.
