Experience the ultimate nightly beauty ritual with the Sleep In Beauty Hyaluronic Acid-Infused Silk Pillowcase. Crafted from luxurious 100% pure 22 momme mulberry silk, this pillowcase is designed to transform your skin and hair while you sleep. Hyaluronic acid is infused into the silk fibers using a unique micro-capsulation technology. Unlike cotton, which can draw moisture away from your skin, our silk is infused with Hyaluronic Acid, a powerful hydrator that works overnight to boost skin's moisture levels, helping to plump, smooth, and reduce the appearance of fine lines. Dermatologists and hair stylists recommend SIB silk for its proven anti-aging benefits. Benefits include continuous overnight hydration, clinically proven to help retain skin moisture and boost radiance, and reduced appearance of fine lines & wrinkles. It's also gentle on hair, helping prevent frizz, breakage, and split ends. The pillowcase is naturally cool, breathable, and hypoallergenic, and OEKO-TEX certified for safe, skin-friendly luxury. Features a hidden zipper design with double stitching and comes presented in a premium black & gold gift box. Standard Queen Size: 50 x 75cm.
