What it is: An anti-aging, anti-sleep crease, anti-bedhead pillowcase that's like an eight-hour beauty treatment every night.What it does: Crafted from pure silk inside and out as recommended by dermatologists, plastic surgeons, hairdressers and beauty experts alike, this pillowcase elevates beauty sleep to a whole new level. We spend a third of our lives in bed, so what you sleep on is important. Silk fibers are significantly less absorbent than many other fibers, so they help keep your skin's moisture and expensive face and hair products where they belong-on your face and hair, not your pillow. Ordinary pillowcases can cause hair to pull and tangle throughout the night, leading to bedhead in the morning and potentially damaging hair. The silk can help reduce friction, too, which also aids in reducing stretching and tugging on delicate facial skin. How to use: When washing the pillowcase, we recommend that you hand wash or use a delicates wash bag. Do not tumble dry or bleach. Use a pH neutral liquid detergent and line dry in the shade. Iron or steam on low heat. 20" x 30" Queen; 20" x 36" King Zip closure Hypoallergenic 100% silk Dry clean, hand wash 30ºC/86ºF or machine wash (delicates wash bag recommended), line dry Imported
