FAQS
Questions. Answered.
Is this real mulberry silk?
Yes. 100% Grade 6A mulberry silk, OEKO-TEX certified. No satin, no polyester blends, no shortcuts. Our silk is sourced from controlled farms and tested for over 100 harmful substances. What touches your face for 8 hours a night should be the real thing.
What's momme weight?
Momme (mm) is the standard weight measurement for silk, similar to thread count for cotton. Higher momme means denser, more durable silk. Our pillowcases are 22-momme — the sweet spot between luxurious feel and long-lasting durability. Anything below 19mm feels thin; anything above 25mm feels heavy.
How do I wash it?
Machine wash cold on a gentle cycle with a mild detergent. Use a mesh laundry bag for extra protection. Tumble dry low or hang dry. Do not bleach. Do not iron on high heat. It's much easier to care for than most people think.
Will it actually help with acne?
Silk won't cure acne, but it removes several factors that make it worse. Cotton absorbs your skincare products and breeds bacteria. Silk's smooth, non-absorbent surface means less friction, less moisture loss, and fewer breakouts. Dermatologists routinely recommend silk pillowcases as part of a skin-care routine.
What if it doesn't work for me?
We offer a 30-night sleep guarantee. Try it for a full month. If you don't notice a difference in your skin, hair, or sleep quality, send it back for a full refund. No questions asked, no hoops to jump through.
How is this different from cheap satin?
Satin is a weave, not a material. Most "satin" pillowcases are made from polyester — a plastic-derived fabric that traps heat, doesn't absorb moisture, and offers none of silk's natural benefits. Real mulberry silk is a natural protein fiber with inherent temperature-regulating and hypoallergenic properties that synthetic fabrics simply cannot replicate.
How long does it last?
With proper care, a SŌIE silk pillowcase lasts 2–5 years. Our 22-momme weight is more durable than lighter silks, and the charmeuse weave resists pilling. Most customers replace theirs not because it wears out, but because they want one for every room.
Do you offer free shipping?
Yes. Free standard shipping on all orders, no minimum purchase required. Most orders arrive within 3–5 business days.
