What it is: A limited-edition version of the anti-aging, anti-sleep crease, anti-bedhead pillowcase with a flowery initial embroidered at the corner.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: Slip onto your pillow and settle in for a luxurious night of sleep.
