We spend a third of our lives in bed. By the time we are 60 we will have slept for an average of 20 years. We developed the slip® anti aging, anti sleep crease, anti bed head, pure silk pillowcase because slipsilk™ can help to reduce friction, which can reduce stretching and tugging on delicate facial skin. What could be better than sleeping on a slipsilk™ pillowcase? Wearing a luxurious slipsilk™ sleep mask at the same time (so your beauty sleep isn’t interrupted).
