Enjoy hours of beauty sleep with the Slip Silk Queen Pillowcases, pure silk bedding that has been specially-commissioned and scientifically tested to provide anti-ageing, anti-sleep crease and anti-bed head benefits. Unlike standard, synthetic fibre pillowcases, the highest grade (6A) long fibre mulberry silk with a 22 momme thickness has been utilised to create a luxurious night-time experience that is gentle on skin and hair. Refined over ten years to provide the ultimate in shine, thickness, softness and durability, the SlipSilk™ pillowcase has been shown to significantly reduce friction. It allows skin to breathe and glide, which reduces pressure on creased skin and prevents hair from tangling and becoming damaged during sleep. Less absorbent than traditional pillowcases, it also protects the integrity of recently applied face creams to help maintain skin's moisture. Crafted under stringent regulations with certified non-toxic dyes, the luxurious pillowcase is recommended by dermatologists and beauty experts. A natural temperature regulator, it will promote a comfortable night's sleep. Expect smoother-looking skin and tame hair come morning. 100% Silk Naturally dust-mite resistant. Hypoallergenic.
