A silk pillowcase could very well be the smartest beauty product you ever invest in. Sounds crazy, I know. But this 100% Mulberry silk pillowcase avoids the friction a cotton pillowcase can cause between your skin and the pillow (who knew?!). This means it prevents sleep creases that can eventually turn into permanent wrinkles (ah!). AND will not absorb your skin’s moisture or whatever cream you apply before bed. Did we mention it’s hypoallergenic?
