A great question – well put!
My friend says her silk pillowcase fights wrinkles. Is she bonkers?

No, she’s right. Silk doesn’t crease and leave imprints on your face as much as cotton, so you wake up with fewer lines. It also stops skin drying out and prevents static, knotty bed-head hair. So they’re a good investment!
