Is silk hypoallergenic?

Yes. Pure Mulberry silk is naturally hypoallergenic. It resists dust mites, mold, and bacteria — making it ideal for people with allergies, eczema, or sensitive skin. More Sunday silk is also OEKO-TEX STANDARD 100 certified, meaning it has been tested and confirmed free of harmful chemicals.

Why is silk better for sleep?

Silk is thermoregulating, meaning it adapts to your body temperature — keeping you cool when it's warm and warm when it's cool. This prevents the overheating or chilling that disrupts sleep cycles. Silk is also smooth against the skin, reducing friction and irritation that can cause restlessness.

Is silk sustainable and eco-friendly?

Yes. Natural Mulberry silk is 100% biodegradable and produced without synthetic pesticides. More Sunday silk is OEKO-TEX STANDARD 100 certified and produced with sustainability at every stage — from sourcing and dyeing to manufacturing and packaging.

Why Silk? The More Sunday Difference | Best Fabric for Sensitive Skin

Q: What are the skin benefits of wearing silk?

Silk contains 18 naturally occurring amino acids that interact positively with human skin. These proteins help soothe irritation, support skin regeneration, and maintain moisture levels. Silk is also gentle on hair, reducing breakage and frizz. Unlike cotton or synthetic fabrics, silk does not absorb moisture from your skin.

Pure Mulberry silk is the only fabric that is simultaneously hypoallergenic, thermoregulating, antimicrobial, biodegradable, and rich in skin-nourishing amino acids. Nothing else comes close.

Silk is uniquely thermoregulating — it reads your body temperature and responds, keeping you cool when you're warm and warm when you're cool. This prevents the temperature spikes that pull you out of deep sleep cycles.

If you've ever woken up sweating at 3am or shivering by morning, your fabric is working against you. Silk works with you.

Do less laundry

Silk is naturally antimicrobial, actively repelling dust mites, bacteria, mold, and bugs without any chemical treatment. This means you genuinely don't need to wash it as often as cotton or synthetic fabrics — saving time, water, and energy.

Less washing also means your pieces last longer, reducing waste and keeping your investment looking beautiful.

Silk contains 18 naturally occurring amino acids — the same building blocks as human skin — that actively soothe, support skin regeneration, and maintain moisture levels rather than stripping them away. It's why dermatologists often recommend silk for eczema, rosacea, and reactive skin.

Unlike synthetic fabrics or even cotton, silk creates zero friction against skin and hair, reducing irritation, breakage, and morning creases.

The science of silk

Why silk is in a category of its own

Mulberry silk — produced by Bombyx mori silkworms fed exclusively on white mulberry leaves — is the highest grade of natural silk available. Its uniquely fine, long filaments create a fabric with properties no synthetic can replicate.

The protein structure of silk (sericin and fibroin) is chemically compatible with human skin, which is why it doesn't trigger immune responses in people with allergies or sensitivities. It's not just soft — it's biologically gentle.

When you choose OEKO-TEX® certified silk like More Sunday's, you're also choosing a fabric that has been independently tested and verified free of over 100 harmful substances — including formaldehyde, heavy metals, and pesticide residues.

Everything you've wondered
about silk

What is the best fabric for sensitive skin?

100% Mulberry silk is widely considered the best fabric for sensitive and reactive skin. Its protein structure is biologically compatible with human skin, it contains 18 amino acids that soothe and support regeneration, and it creates zero friction. Unlike synthetic fabrics or treated cotton, silk does not disrupt the skin barrier or trigger immune responses.

Is silk truly hypoallergenic?

Yes — pure Mulberry silk is naturally hypoallergenic. It resists dust mites, mold, mildew, and bacteria without any chemical treatment. People with eczema, rosacea, psoriasis, or general skin sensitivity often find silk the only fabric they can sleep and lounge in comfortably. More Sunday silk is also OEKO-TEX® STANDARD 100 certified, independently verified free of harmful substances.

Why is silk the best fabric for better sleep?

Silk's thermoregulating properties mean it responds to your body temperature in real time — preventing the overheating and chilling that interrupt sleep cycles. It's also naturally smooth, reducing tossing and turning caused by fabric friction. Studies link thermoregulation during sleep to improved REM quality and overall restfulness.

Is silk actually sustainable?

Natural Mulberry silk is one of the most sustainable textiles available. It's 100% biodegradable, produced without synthetic pesticides, and has a significantly lower environmental footprint than synthetic fabrics which shed microplastics and take centuries to decompose. More Sunday silk is also OEKO-TEX certified, ensuring every step of production meets strict environmental and safety standards.

What does OEKO-TEX® STANDARD 100 mean?

OEKO-TEX® STANDARD 100 is one of the world's most rigorous independent textile certifications. It means every component of the fabric — threads, dyes, finishes — has been tested and verified free of more than 100 harmful substances, including formaldehyde, heavy metals, pesticide residues, and known allergens. It's the assurance that what touches your skin is genuinely safe.

How does silk benefit skin compared to cotton?

Cotton is absorbent, pulling moisture away from skin and hair. Silk, by contrast, maintains your skin's natural hydration while its amino acids actively support regeneration. Cotton also has a coarser weave that creates friction against delicate skin; silk's smooth surface eliminates that friction entirely — which is why it's recommended for hair health, reducing breakage and morning frizz.
