Wearing a luxurious Slip Silk sleep mask at the same time (so your beauty sleep isn’t interrupted). THE SLIPSILK DIFFERENCE: Slip Pure Silk products are made using Slip Silk, developed and refined for over ten years to provide the ultimate combination of shine, thickness, softness and durability. In laboratory testing, Slip Silk pillowcases were shown to absorb significantly less face cream than cotton pillowcases*, so they can help keep your skin’s moisture and valuable face and hair products where they belong, on your face and hair. Slip Silk was also shown to create 43% less friction on average*, which can reduce stretching and tugging on delicate facial skin. *On average compared to cotton pillowcases with a 220-360 thread count.
