Silk pillowcases used to feel like a bit of an indulgence. Now they are everywhere. From dermatologists and hair stylists to sleep coaches and beauty editors, everyone seems to be recommending them. They get name-checked by celebrities like Kristen Bell and Kim Kardashian, show up in countless TikTok routines, and regularly feature in conversations about better skin, smoother hair, and more comfortable sleep.
But behind the hype, a fair question still hangs in the air. Are silk pillowcases actually doing anything useful, or are they just a glossy, expensive upgrade that feels nicer than it performs?
We look at what the science really says, how silk pillowcases perform in everyday use, and which options are actually worth considering in the UK. The goal is simple: to work out whether silk deserves a permanent place on the bed, or whether cotton is doing the job just fine.
Silk vs Cotton Pillowcases: What’s the Real Difference?
Silk and cotton may both be soft to the touch, but they perform very differently when it comes to sleep, skincare, and overall comfort.
Friction
Cotton pillowcases can tug and pull on facial skin and hair during the night. This friction contributes to sleep lines on the face and hair breakage. Silk, by contrast, offers a glide-like texture that reduces mechanical stress on skin and strands.
Moisture Absorption
Cotton is highly absorbent, meaning it draws moisture from the skin, hair, and even products applied before bed. Silk, on the other hand, is much less absorbent and helps preserve hydration. This is particularly valuable for those using night serums or moisturisers.
Temperature Regulation
Silk is naturally temperature-regulating due to its protein structure and breathable weave. Cotton, while breathable, lacks silk’s ability to adapt to changes in body temperature, often leading to overheating.
Durability and Feel
While cotton comes in varying grades (e.g. Egyptian, Pima), silk is graded in momme (a measure of weight and quality). The softness and smoothness of a high-momme mulberry silk pillowcase are superior to most high-thread-count cotton alternatives.
Skincare Benefits of Silk Pillowcases
Fewer Sleep Creases and Potentially Fewer Wrinkles
Side sleepers and stomach sleepers often wake with deep creases on one side of the face. Over time, these can contribute to the formation of permanent lines. Silk minimises this risk by allowing the skin to glide, not drag.
Hydration Retention
Those with dry or eczema-prone skin often struggle with maintaining moisture overnight. Silk’s lower absorbency helps retain the skin’s natural oils and topical products.
This benefit is especially valuable during colder months when indoor heating exacerbates dry skin. Silk’s gentle surface provides a low-irritant option for individuals with conditions like psoriasis or contact dermatitis.
Reduced Skin Irritation and Redness
People with sensitive skin or inflammatory conditions often report that silk pillowcases reduce redness and itchiness overnight. This is due to silk's smooth texture and minimal contact resistance.
Hair Benefits of Silk Pillowcases
Reduces Frizz and Morning Tangles
The reduction in friction with silk leads to noticeably fewer tangles in the morning, especially in longer hair. Curly-haired individuals report fewer knots and better curl definition after switching to silk.
Hair stylist Andrew Walker told Women's Health Magazine:
"Standard cotton cases are known to cause breakage and split ends. Silk pillowcases help to maintain your style, in addition to keeping your curls and coils from frizzing and straightening out"
Minimises Breakage and Split Ends
Hair is more fragile when wet or during movement. Traditional pillowcases can rough up the cuticle layer. Silk offers a protective barrier that reduces stress on the hair shaft.
Extends the Life of Hairstyles and Hair Treatments
For those who spend time and money on keratin treatments, hair colouring, or straightening, silk helps prolong results. It doesn’t strip product residue or absorb oils, so styles last longer.
Sleep Benefits of Silk: Comfort and Cleanliness
Temperature Adaptability
Silk is thermoregulating, which means it keeps the sleeper cool in summer and warm in winter. This helps prevent overheating — one of the most common causes of nighttime wake-ups.
Hot sleepers and women experiencing perimenopausal or menopausal symptoms (like night sweats) often find relief with silk.
Hypoallergenic Properties
Silk has natural resistance to dust mites, mould, and fungus. These properties make it a wise choice for those with:
Allergic rhinitis
Asthma
Eczema
Sensitive immune systems
Combined with regular washing, silk pillowcases can contribute to a cleaner and healthier sleep space.
Silk Pillowcases and Acne: What the Experts Say
Though not a cure for acne, silk may help reduce breakouts caused by skin irritation or product absorption according to one study.
Also speaking to Women's Health Magzine, Gary Goldenberg, M.D. noted:
“Patients with acne or acne-prone skin may benefit from high-quality silk since it doesn’t clog pores.”
However, it’s important to pair a silk pillowcase with other hygiene practices:
Wash the pillowcase at least once per week
Avoid going to bed with makeup on
Change pillow inserts monthly
While clinical studies on acne reduction are limited, anecdotal evidence and logic support the role of silk in minimising irritation for acne-prone individuals.
Who Will Benefit Most From Silk Pillowcases?
The benefits of silk are widely appreciated by:
People with curly, frizzy, or brittle hair
Individuals prone to dry skin or eczema
Those undergoing dermatological treatments or laser therapy
Menopausal or perimenopausal women experiencing night sweats
Allergy sufferers and asthma patients
People using retinoids, vitamin C serums, or other strong actives
Even children with sensory sensitivities may benefit from silk’s soft, low-resistance texture.
How to Choose the Best Silk Pillowcase in the UK
What to Look For:
When choosing a silk pillowcase, a few details make a real difference. Momme count is one of the most important. A range of around 19 to 25 momme tends to strike the right balance, feeling soft and luxurious while still holding up well over time. Lower momme silk can feel flimsy, while higher counts quickly push the price up without adding much benefit.
The type of silk matters too. Look for 100% mulberry silk, ideally graded at 6A, which is considered the highest quality and offers a smoother, more consistent weave. Anything blended or vaguely labelled is unlikely to perform as well.
Closure style is mostly about practicality. Envelope closures are common and easy, but a discreet zip keeps the pillow firmly in place and stops it sliding out during the night. Finally, certifications are worth checking. OEKO-TEX Standard 100 indicates the fabric has been tested for harmful substances, which is reassuring given how much time the face spends against it.
Recommended UK Brands:
Slip: One of the most luxurious options (22 momme).
This Is Silk: British brand, affordable and OEKO-TEX certified.
Drowsy Sleep Co.: Specialises in silk sleep masks and pillowcases.
John Lewis & Partners: Mid-range, well-reviewed options.
Marks & Spencer: Entry-level pure silk at an accessible price point.
Caring for a Silk Pillowcase: Maintenance Without the Stress
Silk may have a reputation for being high-maintenance, but it is actually straightforward to look after once the basics are covered. Washing should be kept gentle. Hand washing is ideal, but a cold, delicate machine cycle works well too if the pillowcase is placed inside a mesh laundry bag. A pH-neutral or silk-specific detergent helps protect the fibres and keeps the fabric smooth.
Drying is where a bit of care really matters. Silk should be air dried, laid flat, and kept out of direct sunlight, which can weaken the fibres over time. Wringing it out or using a hot tumble dryer is a fast way to ruin the fabric, so both are best avoided.
Stains need a light touch. For marks caused by oils or skincare products, a silk-safe enzyme spray applied before washing is usually effective. Gently blot the area with cold water if needed, but avoid rubbing, which can damage the weave and leave the silk looking dull.
Following proper care ensures a silk pillowcase lasts 1–3 years or more, depending on usage.
Common Concerns and Ethical Considerations
Price
Silk pillowcases typically range from £30–£90, depending on momme, brand, and craftsmanship. While they cost more than cotton, they last longer when cared for properly.
Durability
High-quality silk holds up well but is still more delicate than cotton or bamboo. It’s vulnerable to:
Snags from jewellery
High heat from dryers
Stains from oils or hair products

The upfront cost may be higher, but the long-term payoff in comfort, appearance, and sleep quality makes it a smart investment.
Frequently Asked Questions About Silk Pillowcases
Are silk pillowcases actually better than cotton?
Silk pillowcases do perform differently to cotton. Silk creates far less friction, absorbs much less moisture, and tends to feel cooler against the skin. Cotton is durable and affordable, but it can pull at hair and skin overnight and soak up skincare products. Whether silk is better depends on priorities like skin sensitivity, hair type, and comfort.
Do silk pillowcases really help skin?
Silk is not a cure for skin conditions, but it can help reduce irritation. Because it is smoother and less absorbent than cotton, it allows skin to glide rather than crease and helps keep moisture and skincare products on the face. People with dry, sensitive, or eczema-prone skin often notice fewer sleep lines and less morning redness.
Can a silk pillowcase help with acne?
Silk will not treat acne on its own, but it may help reduce irritation that can make breakouts worse. Silk does not trap oils and bacteria in the same way as rougher fabrics, and it does not absorb products applied before bed. Cleanliness still matters, so regular washing is essential.
Is silk good for hair, or is that just hype?
For many people, the hair benefits are very real. Silk reduces friction, which means less frizz, fewer tangles, and less breakage overnight. This is especially noticeable for curly, textured, or colour-treated hair. Hairstyles also tend to last longer compared with sleeping on cotton.
What momme silk should be chosen for a pillowcase?
A momme count between 19 and 25 is ideal for most people. This range offers a good balance between softness, durability, and price. Anything lower can feel thin, while much higher counts increase cost without adding much practical benefit.
How often should a silk pillowcase be washed?
Once a week is a good rule of thumb. If acne, heavy skincare use, or night sweating are factors, washing every three to four days is better. Gentle washing helps maintain hygiene without damaging the fabric.
Are silk pillowcases good for hot sleepers?
Yes. Silk is naturally temperature-regulating, meaning it adapts well to body heat. Many hot sleepers find silk feels cooler and less clammy than cotton. It can also help people experiencing night sweats feel more comfortable.
Do silk pillowcases last long?
With proper care, a good quality silk pillowcase can last one to three years or more. Longevity depends on momme count, washing habits, and avoiding heat damage or snags from jewellery.
Are silk pillowcases suitable for allergies?
Silk has natural resistance to dust mites, mould, and fungus, which can be helpful for allergy or asthma sufferers. Regular washing is still important, but silk can contribute to a cleaner sleep surface overall.
Are silk pillowcases worth the money?
For people focused on hair health, skin comfort, or better sleep quality, silk pillowcases are often worth the investment. They are not essential for everyone, but for those with sensitive skin, textured hair, or sleep issues linked to overheating or irritation, the benefits tend to justify the cost.
