Why Silk?

Silk isn't a luxury for the sake of it — it behaves differently against skin and hair than any other fabric. Here's what actually matters when you choose it: momme weight, silk grade and certification.

What actually makes silk worth it

Your skin and hair spend 6–8 hours a night against your pillowcase. Cotton is absorbent and creates friction with every movement; silk is smooth and non-absorbent, so skin glides and hair keeps its moisture. Two numbers tell you whether a silk product is worth buying — momme and grade.

Momme = weight, not thread count

Momme measures how much silk is actually in the fabric. Most brands use 19 momme; Lunare uses 22 momme — denser, more durable, with a more substantial drape.

Grade 6A = fibre quality

Silk is graded by fibre length and purity. 6A is the highest recognised grade — long, even fibres that give a smooth, uniform surface.

OEKO-TEX® = independently tested

OEKO-TEX® Standard 100 certification means the fabric has been tested for harmful substances by an independent institute — a claim you can verify, not just marketing.

Silk vs cotton vs polyester satin

Mulberry silk Cotton Polyester satin
Friction on skin & hair Minimal — hair glides, skin doesn’t crease High — snags cuticles, presses lines into skin Low at first, degrades with washing
Moisture Non-absorbent — skincare stays on your skin Absorbs moisture and skincare products Traps sweat against the skin
Temperature Thermoregulating — cool in summer, warm in winter Holds heat once warm Doesn’t breathe — runs hot
Fibre Natural protein fibre, hypoallergenic Natural plant fibre Plastic
Feel over time 22 momme holds its structure for years Roughens with washing Pills and loses sheen

Worth knowing

How can I tell real silk from fake?

Real silk is a natural protein fibre — it feels cool at first touch and warms to your skin, and it never comes with a ‘polyester’ label. Check the momme weight, the grade, and whether the brand can name its certification. If a listing says ‘satin’ without a fibre, it is almost always polyester.

Why does a silk pillowcase cost more than cotton?

A 22-momme pillowcase contains a large amount of pure silk fibre, reeled from mulberry-fed silkworm cocoons and woven densely. Certified 22-momme, Grade 6A pillowcases typically sell for £59–£110 from premium silk brands. Ours is £50.99 — the same specification, priced honestly.

Where should I start?

Most customers start with a scrunchie or the pillowcase, then add the eye mask. The Ritual Set brings all three together — worth £95.97 separately, £71.99 as a set.
