Material Deep Dive
Frequently Asked Questions
Is satin the same as silk?
No. Satin is a weave pattern, not a fiber. Most affordable satin pillowcases are made from polyester, which is a synthetic plastic-based fiber. Silk is a natural protein fiber produced by silkworms. Silk satin exists (silk woven in a satin weave), but most products labeled 'satin' are polyester.
Is silk worth the extra cost over cotton?
For sleep quality, hair health, and skin benefits, yes. Silk reduces friction (less frizz, fewer sleep creases), regulates temperature better, and does not absorb your skincare products. The cost per use over a 2-3 year lifespan works out to just pennies per night.
Can I get the benefits of silk from satin?
Satin offers some friction reduction due to its smooth weave, which can help with hair. However, polyester satin lacks the natural moisture-wicking, hypoallergenic, and temperature-regulating properties of real silk. It is also not breathable, which can cause overheating.
What momme count should I look for in silk?
For pillowcases and sheets, 19-25 momme is ideal. Lower momme (16-19) feels lighter and is more affordable but less durable. Higher momme (22-25) is denser, more luxurious, and longer-lasting. Promeed uses 23-momme silk, which is in the sweet spot of quality and durability.
Making the Switch
If you have been sleeping on cotton your whole life, switching to silk can feel like a bigger decision than it needs to be. Here is some practical advice to make the transition smooth.
Start with a single pillowcase. You do not need to replace your entire bedding set at once. A silk pillowcase is the single highest-impact upgrade you can make, since your face and hair are in direct contact with it for 7-8 hours every night. Try one pillowcase for a few weeks. If you like it (and you almost certainly will), you can add a second pillowcase, then consider sheets or a duvet cover down the line. This approach also keeps the upfront cost manageable.
Expect a short adjustment period. Silk feels different from cotton. It is cooler to the touch, slipperier, and lighter. The first couple of nights, you might notice the pillow moves around more inside the case, or that the fabric feels unfamiliar against your skin. This is completely normal. Most people adjust within 3-5 nights, and after a week, going back to cotton feels rough by comparison. If your pillow slides around, a pillowcase with a zipper closure (like Promeed's) helps keep everything in place.
Learn the care basics before your first wash. Silk is not as fragile as people think, but it does need a bit more attention than tossing it in with your regular laundry. Use a mesh laundry bag (Promeed includes one for free), wash on a gentle or delicate cycle with cold water, and use a mild detergent. Skip the dryer and lay the pillowcase flat to air dry. The whole process takes about two minutes of extra effort. Once you have done it a couple of times, it becomes second nature.
Keep realistic expectations about stains. Silk is a natural protein fiber, and while it resists dust mites and bacteria, it can stain from oils and makeup. If you use heavy night creams or serums, give them a few minutes to absorb before lying down. For spot cleaning, dab gently with cold water and a tiny amount of mild soap. Never use bleach or hot water on silk.
The bottom line: switching to silk is one of those small changes that pays off immediately. You will notice the difference in your hair and skin within the first week, and the better temperature regulation means fewer middle-of-the-night wake-ups. It is a surprisingly easy upgrade for something that affects a third of your life.
