Most sleep masks fail because the band is fixed. Ours is silk-covered velcro, so you set the tension once and it stays there all night.

"Your eyelids are thin enough that light passes straight through them. Your brain keeps reading that light all night and holds you in a shallower stage of sleep. Block the light completely and your body finally gets to go all the way under."

Mulberry Silk Deep Sleep Mask
Your first 30 Nights
This is not a supplement. There is no ramp-up period. But the difference between night one and week four is bigger than most people expect.
Night 1
Total darkness
You put it on and the room disappears. Most people notice they fell asleep faster before they notice anything else.
Week 1
No more 3am
You stop waking up to a lit room at 3 or 4am. If you have been checking the clock every night, that is usually the first thing to go.
Week 2
A clearer morning face
The morning crease under your eye is gone. So is the red groove across your temple that the cheap elastic used to leave.
Week 4
It becomes automatic
You stop thinking about it. You just do not sleep without it anymore, and you buy a second one for your travel bag.
Why choose Helvari
Most sleep masks fail for the same three reasons. We fixed all three.

8 Layers, Not One
Cheap masks are a single thin sheet sitting flat on your eyelids. Light goes right through. Ours is built in eight layers and wraps wide past the corner of your eye.
It Stays Where You Put It
Silk-covered velcro adjusts to your actual head instead of squeezing it. No fixed elastic. No plastic buckle digging into your skull while you lie on it.
Silk on Both Sides
Most "silk" masks are silk outside and polyester on the side touching your face. That is the side that grips your skin and creases it. Ours is 6A mulberry silk all the way through.
The problem with your dark room
Your bedroom is not as dark as you think, and your brain notices even when your eyes are shut.

It Slid Off By Midnight
+
Fixed elastic stretches over your head and then works itself loose. Our silk velcro sets to your size and stays. You wake up with it still on.
Light Came In At The Sides
+
A flat rectangle only covers your eyes. Turn your head and light comes in at the corner. Ours wraps wide past your temples.
It Pressed On My Lashes
+
The 8-layer padded build sits above your lids instead of flat against them. Safe for lash extensions and long natural lashes.
I Woke Up With A Crease
+
Cotton and polyester grip your skin and hold it folded for seven hours. Silk lets your face slide instead. That is why the side touching you being real silk actually matters.
The Strap Marked My Face
+
No plastic buckle. No thin cord. A wide silk-covered band that spreads the pressure instead of digging one line into your temple.
It Made Me Sweat
+
Silk is naturally breathable and temperature regulating. It does not trap heat against your face the way synthetic satin does.
Your Questions Answered
30-night risk-free trial. Money back to your card.
How do I know it is real silk?
+
Look for two numbers. Grade and momme. Ours is 6A grade, 19 momme, stated right on this page. Sellers offering "silk" masks for four dollars cannot state either, because most of them are polyester and spandex with the word silk in the title.
Does it work for side sleepers?
+
Yes, and this is what it was designed around. The strap adjusts with silk velcro instead of stretch elastic, and the mask lies flat against your temple so there is nothing bunched between your head and the pillow.
Is it safe for lash extensions?
+
Yes. The padded 8-layer build means the fabric is not resting directly on your lids or lashes.
How do I wash it?
+
Hand wash in cold water with a gentle detergent. Lay it flat to dry away from direct sun. Do not wring it out. Cared for properly it lasts years.
How fast does it ship?
+
Orders leave within 1 to 3 business days and typically arrive in 5 to 8 days after that. Free shipping inside the US.
What is your return policy?
+
Sleep in it for 30 nights. If it does not work for you, send it back and we refund you to the card you paid with. Not store credit.
Will it help me fall asleep faster?
+
It blocks light, and light is one of the main reasons people wake up in the night and struggle to drift off. What it does not do is treat insomnia or replace medical advice. If your sleep problems are serious, talk to a doctor.
