Silk pillowcases are much gentler on your skin and hair compared to traditional pillowcases. Traditional pillowcases tug on your skin and hair throughout the night, thus causing wrinkles, skin inflammation and bed head. Silk is a natural fabric and is hence believed to be more compatible with our skin and hair.  Silk is also naturally hypoallergenic, making it perfect for people with sensitive skin and allergy sufferers. Satin while smoother than traditional pillowcases, is a synthetic weave and do not have the benefits associated with silk being a natural fibre.
