Mulberry Park Silks checks out three "infused" silk pillowcases and reveals why you're paying more for less (and what savvy shoppers should buy instead).
Key Takeaways
- The “special benefits” of infused pillowcases are just silk benefits rebranded — High-quality mulberry silk already delivers smoother hair, healthier skin, and reduced friction with no additives required.
- Infusions fade quickly or lack scientific backing — Aloe vera rinses out after 10–20 washes; silver has no clinical evidence for skin or pillowcase benefits; copper studies were limited and industry-funded.
- Most infused pillowcases cost more while offering less — Many aren’t pure silk, fail to disclose fabric quality like momme weight, and often carry a 50–200% markup compared to genuine Grade 6A mulberry silk.
Savvy Shopper Alert: The Infused Silk Pillowcase Trend
If you've been shopping for silk pillowcases, you've probably seen them: copper-infused for anti-ageing, silver-infused for acne, aloe-infused for sensitive skin. They promise "medical grade" benefits and cost anywhere from $90 to $133.
As silk pillowcase experts, the Mulberry Park Silks team is naturally skeptical of these claims, mostly because we know that silk fabric can deliver these benefits all by itself. We took a look at three popular infused pillowcases-Coppry (copper), Clementine Sleepwear (silver), and Cozy Earth (aloe vera)-and broke down their marketing claims vs actual benefits. What we found: you're often paying premium prices for products that are either inferior quality, make unproven claims, or contain treatments that quite literally wash away in weeks.
What Are Infused Silk Pillowcases?
The infused silk pillowcase trend involves manufacturers adding copper, silver, aloe vera, or other substances to silk fabric. The claims are impressive: anti-ageing properties, antibacterial benefits, healing powers, and enhanced hydration.
These products lean heavily on medical-sounding language: "medical grade," "clinically proven," "revolutionary technology." They position themselves as the next evolution of silk, suggesting that regular silk isn't enough anymore.
Three Infused Pillowcases: A Closer Look
Coppry: The Copper-Infused "Silk" Pillowcase
Price: $110 (king)
The Claims: Anti-ageing solution that stimulates collagen production, reduces wrinkles, and helps manage acne by eliminating 99.9% of bacteria.
The Reality: Coppry's fabric is only 51% silk and 49% copper polyester. Buyers are paying luxury prices for a half-polyester blend, losing many of pure silk's natural benefits.
The scientific backing for copper infusion is interesting. There have been several studies backing up the effectiveness of copper-infused silk, with the most regularly cited study funded by the copper textile industry. This study had a small sample size, ran for around two months, and showed that copper-infused pillowcases did minimise wrinkles and crow's feet. However, the study did not test copper-infused silk fabric, nor did it compare the benefits of sleeping on copper-infused silk with regular pure mulberry silk. This leaves big questions about whether and by how much (if any) copper adds to the benefits of real silk. In fact, the comparison chart on the Coppry website compares the product to cotton pillowcases, not silk.
Bottom Line: Premium prices for a polyester blend; industry-funded research is limited by failing to compare the copper pillowcase to silk.
Clementine Sleepwear: The Silver Ion Silk Pillowcase
Price: $169 (King)
The Claims: "Medical grade luxury" that's "clinically shown to restore skin and hair health"; "actively eliminates 99.9% of acne-causing bacteria."
The Reality: Although the marketing language invokes medical terminology, silk pillowcases are not FDA regulated. The term "medical grade" has no legal definition for pillowcases; it is purely marketing language. Also, the claims made about the Silver Ion Silk Pillowcase include being sustainable, gentle on sensitive and acne-prone skin, and containing hydrating proteins for hair. All of these can be said about pure mulberry silk fabric. On the plus side, the Silver Ion Silk Pillowcase is GOTS-certified organic.
Bottom Line: At $135, this is the most expensive option, yet Clementine doesn't disclose momme weight. For a product making medical claims and charging premium prices, this lack of transparency is concerning.
Cozy Earth: The Aloe Vera-Treated Silk Pillowcase
Price: $88 (King)
The Claims: "Treated with aloe vera" to provide "additional soothing benefits" for skin and hair.
The Reality: The aloe vera treatment washes out. Multiple published textile research studies demonstrate that aloe vera treatments wash out of fabric in 10-20 launderings. Nest Bedding-a competitor making a similar product-explicitly admits their aloe treatment "can withstand up to 10 washes." Cozy Earth doesn't disclose this anywhere. If you wash your pillowcase weekly, the aloe vera is gone within 2.5 months.
Bottom Line: Cozy Earth prices are a bit more in line with "regular" silk, but they don't disclose momme weight so you really do not know how durable your pillowcase will be. They are also selling a "benefit" that vanishes quickly.
The Truth About Pure Silk Pillowcases (No Infusions Required)
The benefits these infused products claim are often the natural properties of pure mulberry silk. This deceptive marketing presents silk's inherent qualities as if they come from the infusions.
"The beauty of silk lies in its natural protein structure," explains Kendra Cosenza, Brand Manager at Mulberry Park Silks. "Pure mulberry silk already offers everything these infused products promise. Its smooth surface reduces friction that causes hair breakage and sleep wrinkles. It's naturally hypoallergenic, resisting dust mites and mold. Unlike cotton, which absorbs moisture from your skin and hair, silk's non-absorbent fibers maintain your skin's natural hydration and keep your skincare products on your face, not your pillow case."
The Benefits of 100% Pure Mulberry Silk Pillowcases
Reducing Friction: The smooth silk fabric creates significantly less friction than a cotton pillowcase or satin pillowcase, preventing frizzy hair, bedhead, and sleep creases that can become permanent wrinkles.
Naturally Hypoallergenic: Pure silk is inherently resistant to dust mites, mold, and fungi-ideal for those with allergies without any infusions needed. The silk fiber creates an inhospitable environment for allergens, making it nearly impossible for them to thrive.
Maintaining Moisture Balance: Unlike cotton, which absorbs water, silk's non-absorbent surface doesn't strip moisture from your skin and hair. This prevents fine lines and maintains healthy hair.
Temperature Regulating: Silk's natural breathability and temperature-regulating attributes help you stay cool in summer and warm in winter; benefits that cotton and satin simply cannot offer.
Protein Structure: Silk contains natural amino acids that are beneficial to both skin and hair health with no infusions required.
You don't need copper, silver, or aloe to get these benefits. You need high-quality mulberry silk from a trusted, transparent brand like Mulberry Park Silks.
What to Look for Instead: The Mulberry Park Silks Difference
When shopping for silk pillowcases, demand transparency about these quality indicators:
Momme Weight: This measures silk density and quality. A 22 momme silk pillowcase offers the ideal balance of durability and luxurious softness at an accessible price point. A real silk pillowcase will note the momme weight on a tag.
Grade: 6A long-fiber mulberry silk represents the highest quality available.
100% Pure Silk: Not blends, not silk satin (often polyester). A 100 mulberry silk pillowcase delivers unmatched softness and genuine benefits.
Organic or OEKO-TEX Certification: Ensures your silk products are free from harmful chemicals, an important standard for something touching your facial skin eight hours nightly.

Frequently Asked Questions
Do copper-infused pillowcases really reduce wrinkles?
While the studies indicate they do, the research was funded by a copper textile manufacturer. Furthermore, Coppry pillowcases are only 51% silk-a polyester blend. Lastly, Coppry was never evaluated in comparison to pure silk pillowcases, which already reduce sleep wrinkles without the addition of copper.
Is "medical grade" silver in pillowcases FDA regulated?
No. These pillowcases are not FDA regulated. Brands state products are "not intended to diagnose, treat, cure, or prevent any disease." "Medical grade" has no legal definition for pillowcases-it's marketing language borrowing credibility without proof.
How long does aloe vera last in an infused pillowcase?
Studies show aloe vera washes out in 10-20 launderings. With weekly washing, it's gone within 2.5 months.
What should I look for when buying a silk pillowcase?
Demand transparency: momme weight (a 22 momme silk pillowcase is ideal), Grade 6A construction, 100 mulberry silk (not blends), and OEKO-TEX or GOTS certification. Satin options won't match pure silk quality.
Are pure silk pillowcases antibacterial and good for allergies?
Yes. A mulberry silk pillowcase is naturally hypoallergenic, resistant to dust mites and mold, creating an antimicrobial environment through its breathable protein structure. These are inherent properties of highest quality silk-no infusions required. Unlike cotton or satin, a luxury silk pillowcase maintains moisture balance and reduces friction naturally for your skin and hair.
How do you wash a pure mulberry silk pillowcase?
Wash your silk pillowcase by hand or in the machine in a silk-only load. Use a gentle, enzyme-free detergent and put your silk pillowcase in a mesh wash bag.
