ENGINEERED FOR ENDURANCE

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.

Frequently Asked Questions

How do I wash my silk pillowcase?

To preserve the natural softness and luster of your silk, hand wash in cold or lukewarm water with a pH-neutral detergent. If you prefer machine washing, place it in a mesh laundry bag and wash on the delicate cycle with like colors. Do not wring. Gently press out excess water with a towel, then hang or lay flat to dry. If needed, use a cool iron or steamer on the reverse side.

Is silk good for acne-prone skin?

Yes. Silk is naturally smooth and less absorbent than cotton, which helps reduce friction, irritation, and bacteria exposure that can contribute to breakouts.

What are silver ions and why are they used in ZILK pillowcases?

Silver ions are natural particles of silver that help resist bacteria, mold, and other microbes. When infused into ZILK silk, they create a cleaner, fresher sleep surface by preventing up to 99.7% of bacterial growth. This means your pillowcase stays hygienic longer between washes — supporting clearer skin and healthier rest.

How long will my pillowcase last?

With proper care, ZILK’s 25 momme silk maintains its smoothness and durability for years of nightly use.

What is a momme?

Momme (pronounced “mo-may”) is the unit used to measure silk’s weight and quality. A higher momme means a denser weave and more durable fabric. While many silk pillowcases are made with 19 or 22 momme silk, ZILK uses 25 momme — the thickest and smoothest available — so it lasts longer and keeps its luxurious finish wash after wash.
