Our story
How Zilk Was Born
ZILK was created from Elizabeth Cook’s passion for helping people look and feel their best—long after they leave the treatment room.
Why Silk?
As a Physician Assistant and aesthetic expert, Elizabeth always recommended silk pillowcases to preserve skin’s moisture, prevent sleep lines, and reduce hair breakage. When she couldn’t find a high-quality option in the Netherlands, she decided to create one herself.
Science Meets Beauty
With her husband Alejandro’s support, she sourced the highest-grade silk and enhanced it with silver ion technology—adding natural antimicrobial benefits.
Our Mission
A Family Brand
What started as a clinical solution in Amsterdam has grown into an international, sister-powered brand. With Elizabeth’s medical expertise and Katharine’s beauty industry background, ZILK combines science and beauty to create products that truly work while you rest.
The ZILK Promise
We’re a family-owned brand with 37 years of combined experience in beauty. Our mission is simple: to protect your skin, love your hair, and turn sleep into a true beauty ritual.
The Science of Calm
NeuroSilk™ Technology for Mind–Body Restoration
Rest isn’t only about time spent sleeping, it’s about creating the conditions where your body and mind can let go.
ZILK’s NeuroSilk™ technology is inspired by the science of psychodermatology and neurocosmetics—fields that explore how emotions, stress and skin are connected. The goal is simple: support the brain and body as they shift into a calmer state.
Calming Sensory Cues: ZILK’s smooth, cooling sensation activates relaxation responses, signaling to your nervous system that it’s safe to slow down.
Less Friction, More Flow: When your skin and hair glide instead of tugging, it’s a small but powerful signal of ease.
Cleaner Rest, Clearer Mind: Silver ion infusion helps resist bacteria and odor, so your sleep surface feels fresher — reinforcing the ritual of calm.
SCIENCE MEETS SELF-CARE
CRAFTED FOR RESTORATION
ZILK’s silver-infused silk is engineered to support your nightly renewal — reducing friction, resisting bacteria, and helping your skin, hair, and rest stay in balance.
