Three reasons to make the switch to slipsilk™
We spend a third of our lives in bed. In laboratory testing, slipsilk™ 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.
Anti Sleep Crease
Ever woken up with a sleep crease? As skin ages, it loses elasticity and sleep creases—which are caused by friction and pressure on facial skin—can become more pronounced and longer-lasting. While the creases usually go away later that day, they can be gradually ‘ironed in’ over the years.
Sleeping on silk is a great expert beauty tip and a long-time beauty secret. Slipsilk™ has been shown to reduce friction by 43% on average*, allowing skin to glide along the pillow, which can reduce pressure on creased skin.
Anti Bed Head
The world’s most renowned hairstylists have long recommended sleeping on gentle, hair-friendly silk to help preserve your blow out. Ordinary pillowcases can cause hair tangling during the night. In laboratory testing, slipsilk™ has been shown to reduce friction by 43% on average*.
*Compared to widely available cotton pillowcases with 220–360 thread count.
