OUR STORY
Zilk was born out of a passion for helping people look and feel their best—long after they leave the treatment room.
As a board-certified Physician Assistant, international aesthetic expert, and medspa owner in Amsterdam, Elizabeth Cook always gave her clients two essential pieces of advice: use the right skincare products, and sleep on a silk pillowcase. Silk helps preserve skin's moisture, prevent sleep lines, and reduce hair breakage and frizz. When she couldn't find a high-quality silk option in the Netherlands, she decided to create one herself.
We spend a third of our lives sleeping—making it one of the most overlooked opportunities to care for skin and hair. With support from her husband Alejandro, a global business consultant, Elizabeth sourced the highest grade silk on the market and enhanced it with silver ion technology—known for its natural antimicrobial properties. The result: a luxurious, skin- and hair-loving beauty tool designed to protect and prolong the results achieved in the clinic and beyond.
What began as a clinical solution in Amsterdam has grown into an international, sister-powered brand. With Elizabeth's medical expertise and Katharine's two decades in the professional beauty industry, Zilk combines science and beauty to create products that work hard while you rest.
We're a family-owned company with 37 years of combined experience in beauty. Our mission is simple: to provide people with a high-quality product they can lay their head on every night—one that protects their skin, loves their hair, and turns sleep into a true beauty ritual.

SILK VS. COTTON AND SATIN
Silk is a natural, hypoallergenic, and luxurious fiber that is ideal for people with sensitive skin. It lets your hair and skin retain moisture, preventing wrinkles and hair damage. Cotton, while breathable, durable, and affordable, is not as soft or smooth as silk, nor is it hypoallergenic. Most concerningly, cotton quickly traps bacteria after a few nights of use. Zilk's silver ions help prevent over 99.7%* of bacterial and fungal build-up, protecting your skin from breakouts.
INNOVATIVE SILVER ION TECHNOLOGY
Zilk takes the natural benefits of silk a step further by embedding silver ions into our fabric, introducing an antibacterial quality that keeps your pillowcase cleaner for longer. This innovative approach ensures that your pillowcase actively works to prevent bacterial build-up, contributing to clearer, healthier skin. With Zilk, your beauty sleep becomes a source of skin rejuvenation and protection.
