Say ""I do"" to beauty sleep with this ""Just Married"" set of multi-award-winning slipsilk pillowcases. Slipsilk. Laboratory tested. Hypoallergenic. The beauty secret of celebrity hairstylists, dermatologists and beauty experts. Slip Pure Silk products are made using slipsilk, developed and refined for over ten years to provide the ultimate combination of shine, thickness, softness and durability. In laboratory testing, Slip Pure 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. Slipsilk was also shown to create 43% less friction on average,* which can reduce stretching and tugging on delicate facial skin, allowing skin to glide along the pillow, which can reduce pressure on creased skin. Slipsilk also helps avoid the hair tangling caused by ordinary cotton pillowcases. Why switch to a Slip Pure Silk Pillowcase? Real results, real benefits in just four nights!
