"For years I told patients to sleep on silk to protect their skin and hair. When I couldn't find one that met my clinical standards, I made one. ZILK is what I recommend to my patients, and what I sleep on every night."

Silver-infused silk engineered for restorative rest

THE SCIENCE OF BETTER SLEEP

What you sleep on affects how you look and feel when you wake up. ZILK's silver-infused mulberry silk reduces friction and helps your skin hold onto moisture through the night.

The result is smoother skin, less frizz, and a surface that stays cleaner between washes.

The Zilk Sleep Difference

Most skincare routines stop at bedtime. ZILK Sleep picks up where they leave off. Our 25-momme mulberry silk works with your skin and hair while you rest, protecting what you've already invested in and helping you wake up looking like you actually slept.
