The 3 Products I Swear Help My Skin While I'm Sleeping

I cover my most comfortable pillow with a silk pillowcase — like the
Brooklinen Mulberry Silk Pillowcase ($59) — so that I actually use it every single night, and therefore reap the skin-care and hair-care benefits. The slippery, silky fabric is said to help your skin hold on to moisture, hopefully allowing the creams and masks you rub in before bed to make more of a difference. Silk pillowcases also reduce friction — a big win if you have super-sensitive skin or are trying to avoid hair breakage.
