Frequently Asked Questions
Why choose a POSHEY silk pillowcase over cotton or satin?
Cotton creates friction that tangles hair and presses sleep lines into skin. Silk is a natural fiber, while satin fabric is a weave, and many satin options are made from polyester satin or another synthetic fiber rather than real silk. POSHEY uses 100% pure mulberry silk at 22-momme weight - naturally smooth, breathable, and dermatologically safer than synthetic fabrics for sensitive skin. It is also naturally hypoallergenic and resistant to dust mites, which can help reduce allergens for sensitive skin. Silk helps maintain moisture better than cotton, which can be especially helpful for curly or sensitive hair overnight.
How does a silk pillowcase help improve skin?
POSHEY silk pillowcases have been independently lab-tested and shown to reduce friction by 43% compared to standard cotton pillowcases. Less friction means fewer sleep creases, reduced skin tugging, and less absorption of your skincare products overnight. Unlike cotton, silk does not absorb moisture the same way, which helps retain skin hydration for better beauty sleep and supports skin health.
What momme weight should I look for in a silk pillowcase?
22-momme is the gold standard for silk pillowcases: for a mulberry silk pillowcase or silk pillow case, momme count is a better quality indicator than thread count. Lower momme weights (16-19) are thinner, while higher momme means thicker, more durable silk fabric. Higher weights (25+) can feel heavy. 22-momme provides the ideal balance of durability, smoothness, and breathability for silk products, matching what most silk pillowcases aim for in the 19-22 momme range. It also fits the 100 mulberry silk pillowcase standard shoppers expect from the highest quality silk, while weights above 25 momme are less common and usually more expensive.
How do I wash a POSHEY silk pillowcase?
Machine wash on gentle cycle with cold water using mild detergent. For the gentlest care, hand wash a pure mulberry silk pillowcase to help preserve its softness and sheen. No bleach or fabric softener. Air dry flat or, if needed, use machine drying carefully on low heat, though air drying remains preferred. Remove while slightly damp. Wash separately the first time. Gets softer with every wash. Use a mesh laundry bag in the washer, and avoid direct sunlight while drying.
Are POSHEY silk pillowcases certified?
Yes. Every POSHEY silk pillowcase is Oeko-Tex Standard 100 certified, meaning it has been independently tested for over 100 harmful substances and is safe for direct skin contact. Our silk is also Grade 6A - the highest quality classification for mulberry silk, referring to the highest quality silk made from the longest continuous threads, which helps define real silk quality and aligns with OEKO-TEX testing for products free from harsh chemicals.
