The way to get real beauty sleep? Try our Cloud 9 Silk Pillowcase in King size (Standard size available as another item). Hypoallergenic silk is breathable and glides easily to prevent creasing and wrinkles in skin and fall-out, snags, and breakage in hair—preserving youthful looks and professional blowouts. And when it comes to the most productive beauty routine, our 100% High-Grade Mulberry Silk pillowcase is a must. The common cotton pillowcase is highly absorbent, drinking up your nourishing creams and oils and decreasing their effectiveness.
