Silk pillowcases are lovely. They feel soft and smooth on the skin. Advice from "skincare experts" regarding the benefits of silk pillowcases on social media, on-line blogs, and in health and beauty magazines is ubiquitous. Claims include they prevent acne and wrinkles. The use of a silk pillowcase supposedly prevents split ends on hair. They are reported to help the skin retain moisture and minimize chemical exposure (from what particular chemicals I do not know.) Most of these "experts" are well-intentioned but are simply misinformed. Others financially benefit from their claims by selling silk pillowcases although they may still believe such claims to be true. Let's be clear: There are no scientific studies that correlate the use of a silk pillowcase with improved skin or hair health. There is no evidence that sleeping on a silk pillowcase minimizes acne breakouts, minimizes the formation of facial wrinkles, prevents split ends or chemical exposure. So don't expect healthier skin or hair from making such a purchase.
However, silk pillowcases are beautiful. They are a true luxury!
