Why treat yourself to a silk pillowcase? * Silk retains your skin's hydration overnight and does not absorb creams applied to your face. * The silk pillowcase is a true ally for your hair: goodbye to friction, frizz, breakage, and split ends. Hair is shinier, and blowouts/straightening last longer. * Silk is also antibacterial, making it ideal for combating acne and other skin imperfections. * Anti-aging, moisturizing, anti-frizz.
