Beauty sleep: When you can hardly fall asleep most nights, it sounds more like a fairytale than an attainable reality. Overnight beauty products claim to work double-duty while you sleep to help fake those eight hours, while silk pillowcases are touted for having serious beauty benefits, like reducing wrinkles, split ends, and frizz. But can silky bedding really be the path to smoother skin and better hair?

In short, yes — silk pillowcases really do make a difference. After we tested the best silk pillowcases in the Good Housekeeping Institute Textile Lab, many of our editors began sleeping on the luxurious bedding and now swear by silk pillowcases, with one saying, “I realized my cheap pillowcase was the real culprit behind my bad hair days.”
