A silk pillowcase, which in our biased opinion, is one of the smartest beauty products you can invest in.

Here's why: Sleeping on a cotton pillowcase causes friction between your skin and the pillow, which results in sleep creases. Over time these sleep creases turn into permanent wrinkles. Cute! (Not!)

But with a silk pillowcase, crease lines don't exist. Since there is no friction, tugging or pulling with silk, your gorgeous face can glide effortlessly over the pillow all night.

Silk pillowcases also 1) keep your hair shiny and frizz-free and 2) won't absorb your skin's natural moisture (or that face cream you applied before bed) as you sleep.

Hypoallergenic and made from 100% Mulberry Silk, Face Case is a skincare essential, and your cute, crease-free complexion will prove it.
