1. Yes, Silk Pillowcases Really Can Make a Difference- But Perhaps Not in the Way You Think

While silk isn't a miracle cure, its naturally smooth fibres help reduce friction against both your skin and hair while you sleep. Many people find they wake with smoother hair, fewer sleep creases and skin that feels less dry than after sleeping on traditional cotton pillowcases.

For many people, this means waking up with:

• Less frizzy or tangled hair
• Fewer sleep creases on the skin
• Hair that feels smoother and easier to manage
• Skin that feels and looks more hydrated than after sleeping on cotton

Silk is also naturally breathable and temperature regulating, helping to create a cooler, more comfortable sleep environment throughout the year.

The key is to think of a silk pillowcase as part of your beauty and wellbeing routine rather than a quick fix. Like good skincare, the benefits come from using it consistently.

The takeaway: A silk pillowcase supports healthier hair and skin by reducing friction and creating a smoother sleep surface—but quality makes all the difference.

2. Not All Silk Pillowcases Are Created Equal

One of the biggest misconceptions is that all silk pillowcases are the same.

They're not.

Just as you wouldn't compare a cashmere jumper to an acrylic imitation, the same applies to silk.

Many products marketed as "silky" are actually satin made from polyester. Others use lower-grade silk or lighter fabric weights that simply won't last as long.

When comparing silk pillowcases, there are four things worth checking before you buy:

• Is it made from 100% pure mulberry silk?
• Is it Grade 6A, the highest quality available?
• What is the momme weight?
• Is it OEKO-TEX® certified?

If these details aren't clearly stated, it's worth asking why.

The finest silk pillowcases are transparent about the quality of the silk they use because they know it matters.

3. Why 22 Momme Is Worth Paying For

One term you'll come across when shopping for silk is momme. If you're new to silk, you may enjoy our complete guide explaining what momme means and why it matters.

Think of momme as the silk equivalent of fabric density. The higher the momme, the more silk has been woven into the fabric.

Lower weights, such as 16 or 19 momme, can feel beautifully soft when new but are generally lighter and may show signs of wear more quickly.

After researching different silk weights while developing Silk Works, we chose to use 22 momme pure mulberry silk across our entire collection.

For us, it offered the ideal balance of:

• Exceptional softness
• Beautiful drape
• Long-term durability
• Everyday practicality

A high-quality 22 momme silk pillowcase should continue to feel luxurious for years when cared for correctly, making it an investment rather than a short-lived purchase.

The takeaway: If you're buying silk to enjoy night after night, 22 momme offers an excellent balance of comfort, durability and longevity.

4. Grade 6A Silk: Why Fibre Quality Matters

Just as diamonds are graded for clarity, silk is graded according to the quality of its fibres.

Grade 6A represents the highest quality available.

It uses the longest, strongest and most consistent silk filaments, creating a fabric that feels smoother, looks more lustrous and lasts significantly longer than lower grades.

At Silk Works, every pillowcase is crafted using Grade 6A pure mulberry silk.

We made that decision because we wanted every product—from pillowcases to scrunchies and loungewear—to reflect the same uncompromising standard of quality.

It's a choice that prioritises longevity over shortcuts.

5. Silk vs Satin: What's the Difference?

This is one of the questions we're asked most often.

Although they may look similar at first glance, silk and satin are not the same thing.

Silk is a natural fibre.

Satin is a type of weave.

While satin can be woven using silk, many satin pillowcases are actually made from polyester or nylon.

Here's a simple comparison:

 

If you're investing in a pillowcase for its beauty and wellbeing benefits, always check that it states 100% mulberry silk rather than simply "satin".

6. Why Do Some Silk Pillowcases Cost £20 While Others Cost £80?

If you've spent any time shopping for silk pillowcases, you've probably noticed a huge difference in price. At first glance, they may all look similar—but what's underneath the surface can vary dramatically.

The price of a silk pillowcase is influenced by several factors, including the quality of the silk, the weight of the fabric, how it's woven, and the care taken during production.

Cheaper silk pillowcases are often made from lower momme silk, blended fabrics, or even polyester satin marketed as "silky". While they may feel smooth initially, they generally won't offer the same longevity or performance as premium mulberry silk.

A high-quality silk pillowcase should be viewed as an investment rather than a disposable purchase. With the right care, a well-made 22 momme Grade 6A mulberry silk pillowcase can remain beautifully soft for many years.

Instead of focusing solely on the price tag, ask yourself:

• Is it made from 100% pure mulberry silk?
• Does it clearly state the momme weight?
• Is it Grade 6A?
• Is it OEKO-TEX® certified?
• Is it designed to last?

When those boxes are ticked, you're investing in quality rather than clever marketing.

Takeaway: The true value of a silk pillowcase isn't measured by its price today, but by how beautifully it performs night after night.

7. How to Choose the Best Silk Pillowcase

Shopping for silk can feel confusing, especially when every brand claims to offer the "best".

Here's our simple checklist.

✔ Choose 100% Mulberry Silk

Mulberry silk is widely regarded as the finest silk available thanks to its exceptionally smooth, long fibres.

✔ Look for Grade 6A

This is the highest grade of silk and offers superior softness, consistency and durability.

✔ Choose 22 Momme

A 22 momme silk pillowcase strikes the ideal balance between luxurious softness and everyday durability.

✔ Check for OEKO-TEX® Certification

OEKO-TEX® certification means the fabric has been independently tested for harmful substances, offering reassurance that it's gentle on your skin.

✔ Consider the Details

Small details often reveal the quality of a product.

Look for features such as:

• Hidden zip closures
• Beautiful finishing
• Machine washability
• Clear care instructions
• Transparent information about the silk itself

These thoughtful touches often distinguish a premium product from a mass-produced alternative.

Why We Chose One Uncompromising Standard

When we founded Silk Works, one thing became clear very quickly: shopping for silk was surprisingly confusing.

Every brand described their silk as "luxury", yet many failed to explain what actually made one pillowcase different from another.

Rather than offering multiple silk weights or different quality levels, we made a conscious decision to focus on one exceptional standard.

Every Silk Works pillowcase is crafted from 100% Grade 6A, 22 momme pure mulberry silk and is OEKO-TEX® certified.

We chose this specification because we wanted to create products that feel luxurious from the very first night and continue to do so for years to come.

It's the same silk you'll find throughout our collections—from our pillowcases and sleep masks to our scrunchies and loungewear—because we believe exceptional quality should never be compromised.

For us, true luxury isn't about excess.

It's about investing in fewer, better pieces that become part of your daily rituals.

So... Is a Silk Pillowcase Really Worth It?

If you're simply looking for the cheapest option available, then perhaps not.

But if you're investing in better sleep, healthier-looking hair, and a more thoughtful nighttime routine, then a high-quality silk pillowcase is one of the simplest upgrades you can make.

The key is choosing genuine quality.

Look for 100% pure mulberry silk, Grade 6A fibres, 22 momme weight, and OEKO-TEX® certification. These details may seem small, but together they make the difference between a pillowcase that lasts a few months and one that remains beautifully soft for years.

Explore our collection of 22 momme Grade 6A mulberry silk pillowcases, thoughtfully crafted for healthier hair, skin and sleep.

After all, you spend around a third of your life asleep.

Why not make every night count? Because true luxury isn't about having more, it's about choosing better.
