This pillowcase is soft and less absorbent than cotton, allowing the skin to retain its natural moisture and helping to keep your skin soft, hydrated, and crease-free. Silk is anti-static and contains the same protein as human hair, preventing it from becoming dry and brittle ensuring you wake up with healthy, shiny hair. The mulberry silk's hypoallergenic properties include a natural resistance to dust mites, fungus, mold, and other allergens. Natural temperature-regulating properties give silk the ability to stay cool and comfortable when the temperature rises. Soft and gentle, silk also soothes sensitive skin like no other.
