Frequently Asked Questions
Our silk pillowcases create a calmer, cooler, and cleaner sleep environment. The natural qualities of mulberry silk support deeper rest while adding a touch of luxury to your nightly routine.
Comfort You Can Feel
Silk’s ultra-smooth texture helps your body relax, reduces nighttime friction, and provides a soothing, cloud-soft surface to rest on.
Temperature Balance All Night
Silk naturally adjusts to your body temperature. It keeps you cool on warm nights and comfortably warm when the temperature drops.
Breathable + Moisture-Wicking
Air flows easily through mulberry silk, and moisture is drawn away from your skin to prevent overheating and discomfort.
Naturally Hypoallergenic
Silk resists common allergens like dust mites and irritants, making it an ideal choice for anyone with sensitivities or allergies.
Silk supports healthier, more hydrated skin by reducing friction, limiting irritation, and helping your nighttime skincare stay where it belongs—on your face.
Locks In Moisture
Unlike cotton, which absorbs hydration and skincare products, our 22-momme mulberry silk helps your skin retain moisture throughout the night.
Minimizes Fine Lines
Silk creates far less friction than cotton. That means fewer sleep creases, less tugging, and reduced irritation that can contribute to signs of aging.
Supports Clearer Skin
Mulberry silk naturally helps repel bacteria, making it a great option for acne-prone skin. The smooth surface also reduces rubbing that can worsen breakouts.
Gentle on Sensitive Skin
Free from harsh fibers and irritants, silk is soothing for conditions like eczema and psoriasis.
Silk helps maintain your hair’s natural shine, reduces breakage, and keeps it smooth by morning.
Keeps Hair Hydrated
Silk doesn’t draw out your hair’s natural oils, helping it stay soft, shiny, and healthy.
Reduces Breakage + Frizz
The smoother the surface, the less friction. Sleeping on silk helps prevent split ends, frizz, and overnight damage.
No More Morning Tangles
Silk’s glide prevents knots and bedhead, so your hair is easier to manage when you wake up.
Better Sleep
Breathable, cool, soft, and hypoallergenic—silk enhances overall sleep quality and comfort.
Better Skin
Reduced friction and moisture retention help keep skin calm, hydrated, and smooth.
Better Hair
Silk preserves natural oils, reduces breakage, and keeps hair looking shiny and healthy.
