About ZILK Sleep

ZILK Sleep was founded by Elizabeth Cook, a board-certified Physician Assistant and international aesthetic expert who spent years advising patients on skincare and sleep. When she couldn't find a silk product that met her clinical standards, she created one. ZILK's NeuroSilk™ pillowcases, sleep masks, scrunchies and hair bonnets are made with 25-momme mulberry silk, silver-ion infused and Oeko-Tex certified. Designed to reduce friction, resist bacteria and support skin and hair health, every product is built for nightly use and crafted to last. Naturally thermo-regulating and soothing to the touch, ZILK silk creates a cooler, calmer sleep surface — one that signals to the body that it's time to restore. We believe rest is the most overlooked step in any skincare routine. ZILK turns that step into a ritual. Our products are a natural fit for spas, medspas, luxury salons and wellness boutiques. We offer wholesale pricing, clean packaging and a brand story that resonates with beauty-focused clientele.Read their story
