Silk is known to help your skin retain moisture, so if you then use some lotion or serum makeup changes to maintain your skin's moisture before going to bed, a silk pillowcase can wish you luck, even if your face gets on top of it, it won't wipe away your makeup by touching it against the pillowcase and wicks away the excess moisture like a cotton pillowcase.

Silk is the only fabric that does not harbor bacteria and mites. Many fabrics harbor bacteria and mites when they have been exposed to sweat or dust fusion, but silk is naturally antimicrobial, which is why many patients recovering from surgery are recommended to use silk bedding while sleeping to aid in wound recovery.
