Sillo Silk Pillowcases are made from organic, 6A grade, 22 momme mulberry silk. Our silk fabric is infused with silver ions to help keep impurities at bay and remains hypoallergenic for sensitive, acne prone skin. Designed to maintain a smooth feel and sheen, wash after wash. Each Sillo Gift Set includes a complimentary Sillo Care wash bag for easy care.

Silver ions naturally inhibit the growth of microbes on the fabric surface, helping reduce build-up that can irritate skin. The ultra-smooth silk is kinder to skin than rough fibers, helping minimize friction and redness. Sillo supports healthy skin—it's not a medical treatment.

Yes. Naturally hypoallergenic and OEKO-TEX® certified, safe for sensitive and allergy-prone skin.

Queen: 20" x 30” (50 x 70 cm) and King: 20" x 36” (50 x 90 cm).

Absolutely! Sillo silk is breathable and naturally temperature-regulating to keep you cool and comfortable.

Without a doubt! Investing in Sillo silk pillowcases is like investing in the long-term health and happiness of your hair. It's not just a purchase; it's a commitment to waking up with beautiful, manageable hair every morning. Picture it as a little luxury that pays off in the form of silkier, smoother strands – a worthwhile investment in your daily well being.

Yes. The smooth, low-friction surface helps reduce nightly tugging and snags that can lead to breakage and split ends. It also helps hair retain moisture, keeping strands nourished and more resilient.

Yes—silk is less absorbent than cotton, so leave-ins and treatments stay where they belong: on your hair.

Tips for best results:

• Let serums, creams, and sprays absorb/dry for ~10–15 minutes before bed to minimize transfer.
  
• If you use heavy oils, waxes, or hairspray, wash your pillowcase more often (every 3–4 sleeps).
  
• Some topical acne products (e.g., benzoyl peroxide) can discolor fabrics—let them fully absorb before bed and consider rotating cases or choosing a darker colour.

Yes. Low-friction silk minimize tugging and pillow lines so skin looks smoother and fine lines look less noticeable. Less absorbent than cotton, it helps moisturizers stay put—supporting hydration and barrier. Not a wrinkle treatment.

Yes. The hypoallergenic 22-momme mulberry silk is gentle for dry, oily, combination, and sensitive/acne-prone skin. Its smooth, low-friction surface helps minimize irritation, and because silk absorbs less than cotton, your moisturizers stay put—supporting hydration and a healthy skin barrier. Woven-in silver helps keep the fabric feeling fresh between washes. Not a medical treatment.

Sillo uses luxury-weight 22-momme 100% mulberry silk and is woven with silver ions to help the fabric feel fresher between washes (not a spray-on finish).

Gentle for sensitive and acne-prone skin. Not a medical treatment.

Yes. Travel often means recycled air, new linens, and disrupted routines. Sillo smooth, low-friction 22-momme silk helps minimize irritation, it’s less absorbent than cotton so moisturizers stay put, and the woven-in silver helps the fabric feel fresher between washes. Not a medical treatment.

Sillo 22-momme mulberry silk is kinder to skin and hair on the road than regular cotton, and it packs flat for carry-ons.

• Skin-friendly: Low friction helps minimize irritation and pillow lines; silk is less absorbent than cotton, so moisturizers stay put and skin feels hydrated.
  
• Feels fresher, longer: Woven-in silver helps the fabric feel fresher between washes (not a treatment).
  
• Hair benefits: Smooth surface helps reduce frizz, tangles, and breakage—great for preserving curls, blowouts, and protective styles.
  
• All-climate comfort: Naturally breathable and temperature-regulating for planes, hotels, and changing climates.
  
• Travel-ready details: Secure envelope closure; packs light; includes a Sillo Care wash bag for easy rinses on the go.

Yes—Sillo is machine-washable and quick to air-dry.

On-the-go care:

• Use a washer on cold, delicate with a gentle detergent (in the Sillo Care wash bag). Skip bleach and fabric softener.
  
• Air-dry only: lay flat or hang; most climates dry overnight.
  
• To smooth creases, light steam or iron on low (reverse side).
  
• No machine? Rinse cold, press in a towel, then air-dry.

• Machine wash cold, delicate with a gentle (silk-safe) detergent.
• For extra protection, place in the Sillo Care wash bag; wash with similar colours.
• Skip bleach, fabric softener, and high heat.
• Air-dry only (lay flat or hang, away from direct sunlight).
• To smooth, light steam or iron on low (reverse side).
• Wash weekly (more often if you use heavier hair/skin products).
  

Tip: Some acne treatments (e.g., benzoyl peroxide) can discolor fabrics—let products fully absorb before bed or rotate cases/darker colours.

Yes. With proper care (cold, delicate; gentle detergent; air-dry), our 22-momme mulberry silk keeps its smooth, plush feel wash after wash. Skip bleach, fabric softener, and high heat; steam or low-iron on the reverse if needed.

Once a week is ideal. Thanks to woven-in silver that helps the fabric feel fresher between washes, some people can stretch to 10–14 days (especially when travelling or using minimal products). If you’re acne-prone, sweat at night, or use heavier hair/skin products, stick to weekly. Always machine wash cold, delicate; gentle detergent; air-dry, then steam or low-iron on the reverse if needed.

Yes—machine washable. Use cold, delicate with a gentle (silk-safe) detergent, preferably in the Sillo Care wash bag with similar colours. Air-dry only (lay flat or hang), then light steam or low-iron on the reverse to smooth. Skip bleach and fabric softener.

Air-dry only—no tumble dry. After washing, gently press out water (don’t wring), roll in a towel to blot, then lay flat on a clean towel or hang to dry away from direct sunlight/heat. Most cases dry overnight. To smooth, use light steam or low iron on the reverse.

No—skip fabric softener. It coats fibers, dulls silk’s natural sheen, reduces breathability, and can shorten the fabric’s life. Use a gentle silk-safe detergent on cold, delicate, air-dry only, then light steam or low-iron (reverse side) if you want extra softness.

Yes—on low heat and on the reverse side. Air-dry first, then gently steam or use a pressing cloth and the silk/low setting to smooth. Keep the iron moving and avoid high heat, spray starch, and direct contact with labels/zips.

Yes—those are ideal. Just make sure they’re clean and fully dry, then:

• Clean and fully dry first to avoid odours or marks.
• Fold loosely and place directly in your linen closet or a drawer (keep on top of stacks to minimise creasing).
• Separate from rough items (zips/Velcro); avoid plastic bins or vacuum bags.
• Store in a cool, dry place away from sunlight and heat; allow a bit of airflow.

Use a gentle, silk-safe (pH-neutral) detergent. Avoid bleach, fabric softener, enzymes (bio detergents), and optical brighteners. Fragrance-free is best for sensitive or acne-prone skin. Wash cold, delicate and air-dry.

• Act fast: Blot—don’t rub. Work on a clean towel.
• Universal spot clean: Mix a little silk-safe, pH-neutral detergent with cool water (≈1:10). Dab, rinse cool, repeat.
• Oil/makeup/SPF: Dust cornstarch on the spot for 30–60 min to lift oils, brush off, then use the detergent solution. For foundation/mascara, dab alcohol-free micellar water first, then rinse and detergent.
• Protein stains (blood/drool): Rinse cold only. Dab with the detergent solution. Avoid enzymes/peroxide and hot water.
• Stubborn marks: Soak 10–15 min in cool water + silk-safe detergent, then rinse thoroughly.
• Drying: Air-dry only. Check the area before drying fully—heat sets stains.
• Avoid: Bleach, fabric softener, enzyme or “bio” detergents, oxygen bleach, baking soda/alkaline cleaners, vigorous scrubbing, and high heat.
• Heads-up: Benzoyl peroxide can permanently discolor fabrics—let it fully absorb before bed or rotate/darker colours.

Yes. They’re great for silk pillowcases, lingerie/bras (close hooks), hosiery/tights, lace/satin, knitwear (cashmere/merino), baby clothes, swim/activewear, and small items like socks. The fine mesh lets water and detergent circulate while shielding fibers from snags and abrasion—and it keeps sets together.

How to use: Fill up to 2/3, zip fully (tuck the tab), wash cold on delicate with a gentle detergent, and air-dry items. For heavily embellished pieces, hand-washing is still best.
