The 25 Momme silk pillowcase is our Premium range: a dense, structured and exceptionally durable silk. Made from 100% Grade 6A mulberry silk certified OEKO-TEX®, it offers a heavier drape, a deep lustre and superior resistance to repeated washing. Ideal for sensitive skin and fragile hair, it reduces frizz, preserves overnight hydration and lasts up to 7 years with proper care.
The 25 Momme silk pillowcase holds a special place in our range: denser and more durable than our bestselling 22 Momme, it offers an enveloping feel and greater opacity while keeping the same properties of 100% natural Grade 6A mulberry silk. It is the benchmark for dry skin, skin undergoing intensive dermatological treatment, and anyone looking for a long-term beauty investment.
At 25 Momme, the fabric weighs around 68 grams per square metre. This is the density at which silk becomes truly opaque — which also makes it the pillowcase of choice for high-end hotels and for those who want a premium look for their bedding.
The question all our customers ask when they're torn between the two weights. Here is the honest, complete comparison.

For standard everyday use, 22 Momme remains our main recommendation. 25 Momme is the natural choice for dry or sensitive skin, beauty routines rich in active ingredients, and anyone who wants to maximise the lifespan of their investment.

For dry skin that naturally loses moisture during sleep, the difference is noticeable: 25 Momme silk maintains a slightly more humid micro-environment at the skin's surface, without retaining sebum.
Patients treated with high-strength retinol, retinoic acid, topical corticosteroids or aesthetic medicine treatments (injectable hyaluronic acid, laser) will find the 25 Momme silk pillowcase to be the bedding most compatible with their protocol. Zero absorption of active ingredients, zero friction on areas of skin weakened by treatment, no risk of mechanical irritation overnight.
Grade 6A mulberry silk is naturally antibacterial and resistant to dust mites with no chemical treatment, and certified OEKO-TEX® Standard 100 — no chemical allergens in the fabric. The 25 Momme density adds an extra mechanical barrier between the skin and the night-time environment, particularly valued by those with a weakened skin barrier (eczema, psoriasis, dermatitis).
The same anti-friction properties apply to hair. On a 25 Momme silk pillowcase, the surface, slightly denser than 22 Momme, offers an even smoother glide. Particularly recommended for long hair, bleached or badly damaged hair whose cuticle is open and vulnerable to night-time friction, and for smoothing or keratin hair treatments whose effect you want to prolong.
The higher density of 25 Momme makes it slightly more robust in the wash than 19 Momme, though the usual precautions still apply. Machine wash at 30°C on a delicate cycle, with a mild detergent free from enzymes and bleach, and a gentle spin (600 rpm maximum). Dry flat or hang in the shade — never tumble dry. Ironing is optional: slightly damp, on a low heat (silk setting), inside out. With this care, your 25 Momme Grade 6A pillowcase keeps its lustre and its properties for 4 to 5 years.
For standard everyday use, 22 Momme already delivers all the benefits of Grade 6A mulberry silk and remains our bestseller. 25 Momme is the natural choice in three cases: dry or sensitive skin that benefits from the higher density, active beauty routines (high-strength retinol, hyaluronic acid) where every gram of skincare counts, and long-term investment — durability goes from 3-4 years to 4-5 years. The price difference is €4.10 for a pillowcase that lasts one to two years longer.
Momme is the unit used to measure the weight of silk. At 25 Momme, the fabric weighs around 68 grams per square metre — 8 g more than a 22 Momme (60 g/m²). This extra density means a fabric that is more opaque, more resistant to washing and slightly heavier to the touch. Below 16 Momme, silk is too thin to withstand regular washing. 25 Momme is the density at which silk becomes truly opaque and suited to intensive use.
Yes, absolutely. 25 Momme Grade 6A mulberry silk is naturally antibacterial and resistant to dust mites with no chemical treatment whatsoever. It doesn't harbour the bacteria responsible for blemishes, doesn't absorb sebum and causes no irritating friction on inflamed areas. Certified OEKO-TEX® Standard 100, it contains no chemical allergens. For skin undergoing anti-acne treatment, it is the only bedding that doesn't neutralise your active ingredients (retinol, niacinamide, azelaic acid) by absorbing them overnight.
Yes. The smooth surface of 25 Momme silk eliminates the night-time friction that flattens curls and causes frizz. When you wake, curly hair keeps its definition with no extra treatment. The slightly higher density than 22 Momme gives an even smoother glide — particularly appreciated for long, thick or very curly hair. For coily hair, the effect on moisture retention is immediate and measurable from the first week.
Yes, just like the other weights of mulberry silk. The smooth surface removes the repeated night-time friction on the same areas of skin — the main mechanism behind sleep wrinkles. And silk doesn't absorb your anti-ageing skincare: retinol and hyaluronic acid stay active on your skin all night. The 25 Momme density adds extra fabric stability — less movement, less friction on the areas around the eyes and lips that are most affected.
Measure your pillow before ordering. Our 25 Momme silk pillowcase is available in 40x60 cm (standard French rectangular size), 50x70 cm (large rectangular comfort size), 60x60 cm (classic European square) and 65x65 cm (large hotel-style square). If you're torn between two sizes, choose the larger one: a slightly roomy pillowcase fits better and preserves the silk's glide.
Machine wash at 30°C on a delicate cycle, with a mild detergent free from enzymes and bleach, and a gentle spin (600 rpm maximum). Dry flat or hang in the shade — never tumble dry. Ironing is optional: slightly damp, on a low heat (silk setting), inside out. The 25 Momme density makes it slightly more robust in the wash than 19 Momme. With this care, your Grade 6A pillowcase keeps its lustre and its properties for 4 to 5 years.
You have 30 days from receipt to return your pillowcase, provided it is in its original condition, unwashed and unused. The refund is issued within 5 to 10 working days of the return being received and checked.
