Why silk works
You sleep on a pillowcase every night. Make it work for you.
Unlike cotton, silk creates zero friction as you sleep. Less hair breakage, fewer sleep creases, and better moisture retention for your skin and hair.

The SISIMI Difference
Our mission
The multibillion-dollar beauty industry taught us to approach skincare with endless product layering and routines.
Our mission at SISIMI is to end the era of the complex 10-step beauty routine.
We simply want to make wellness feel supportive, not stressful, ensuring your environment does the heavy lifting while you just exist.
Our approach is to upgrade the things you naturally do—sleeping, winding down, waking up—with high-performance, restorative essentials.
Our values
- Minimalism - No 10-step beauty routines. Just sleep, done better because it really is nature's beauty secret.
- Excellence - We exclusively use Grade 6A Mulberry Silk, the global gold standard, to ensure your rest is never compromised.
- Intentionality - We value fewer things, done better. Every Sisimi piece is a deliberate choice to simplify your ritual.
- Care - Every stitch is a commitment to your mental and physical health. We meet you as you show up. No promises of perfection. Just support where it matters most.
- Sustainability - This is our baseline. We prioritize natural, biodegradable protein fibers and ethical production.
Our philosophy
Our philosophy is rooted in Radical Ease —the idea that the most effective routines are the ones that fit seamlessly into your real life.
We have reframed silk from a luxury accessory to a functional health tool. No chemicals, no 10-step rules. It is a gentler way to care for yourself, designed for the lazy glow, and we're proud of it.
Your questions, answered
PRODUCT FAQs
Yes. Cotton is a porous material that absorbs moisture (and your skincare). Our silk is naturally hydrophobic, meaning it keeps the moisture in your skin and hair, preventing dehydration and sleep creases.
Absolutely. Silk is a natural thermal regulator. It wicks away excess heat in the summer and insulates in the winter, keeping your body at the optimal temperature for deep, uninterrupted sleep.
Our pillowcases are made of nothing but silk. 100% Mulberry silk, Grade 6A - the industry's gold standard.
- Hand wash is ideal - But for the busy life, machine wash is perfect. Use a delicate cycle, cold water, and a mesh laundry bag to prevent snags.
- Always use a pH-neutral liquid silk/wool detergent - Avoid bleach or fabric softeners, which can break down the natural protein fibers.
- Never tumble dry - Lay flat in the shade or hang to air dry. Silk dries remarkably fast.
- Iron or steam on a low "silk" setting to bring back that signature high-luster shine.
