Is a Mulberry Silk Pillowcase Worth It

Yes, if what you actually want is less friction on your hair and skin overnight, a certified fabric, and something that holds up to repeat washing. It isn't worth it if you're buying it expecting a treatment for skin aging or hair growth, since it isn't one.

Why mulberry silk costs more than other fabrics

Mulberry silk is a natural protein fibre, reeled from silkworm cocoons in a process that's still largely done by hand. That's the real cost driver, not a marketing markup: cotton is machine-spun from a plant fibre, and polyester satin is synthesized cheaply at scale. Neither can match silk's weave-independent property of being genuinely smooth along the whole fibre length, which is what gives it the low friction the fabric is actually bought for.

What that friction difference actually does

• Less pulling on hair. Hair slides across silk instead of catching, so a night of moving around doesn't strain the same strands over and over.
• Fewer overnight creases. A smooth surface doesn't press a line into skin the way a coarser fabric can, and any mark that does form fades on its own within an hour or two, regardless of what you slept on.
• Less moisture pulled from your skin. Silk absorbs less of whatever's on your face than cotton does, so more of a night cream stays where you put it.

None of that is a claim about skin aging or hair growth. It's a friction difference, and it's real on its own terms.

What to actually check before buying

1. A stated momme figure. 19 to 22 momme is the range that holds up to weekly washing without going stiff or thin. Above that, weight keeps climbing but a pillowcase doesn't need it the way heavier bedding might.
2. OEKO-TEX certification, the independent check for anything harmful left in the dye or finish.
3. Whether both faces are silk. A lot of pillowcases print silk on the photographed side and back it with something cheaper.
4. The closure. A zip keeps the pillow fully enclosed; an envelope fold is simpler but can let a pillow work its way out over a few nights. Neither is wrong, but it's worth knowing which you're buying.

Common questions

Is silk actually better than cotton or satin?

For friction, yes, silk is smoother than both. Whether that's worth the price depends on what you want it for. Cotton is fine if friction isn't your concern; a polyester satin pillowcase splits the difference on price but doesn't breathe as well.

Can I wash a silk pillowcase like a regular one?

No. A cool hand wash with a pH-neutral, silk-specific detergent, then laid flat to dry, is the safe routine regardless of brand. Avoid bleach and the dryer.

Is a higher momme always worth paying more for?

Not past a point. 19 to 22 momme covers what a pillowcase needs to do. Beyond that you're mostly paying for weight the fabric doesn't need.

The Zipper Silk Pillowcase is 22 momme mulberry on both faces, OEKO-TEX certified, with a hidden zip closure. It sits in the pillowcase collection.
