3D Sleep Mask
Total blackout. Zero pressure. Wear it any way you sleep.
Most sleep masks press against your eyes. This one doesn't. The 3D contoured design creates a protective dome over your eyes and lashes — blocking light completely without any contact pressure. No crushed lashes. No dry eyes. Just total darkness and the deep sleep that comes with it.

Most masks press
against your eyes.
Standard sleep masks are flat.
That's the problem.
A flat mask sits directly on your eyelids and lashes. Hours of gentle, constant pressure — enough to flatten lash extensions, dry your eyes, and create discomfort that disrupts your sleep without you realising why.
The 3D dome changes
everything about this.
The contoured structure holds the mask material in an arch above your eyes. Nothing touches your lashes. Nothing touches your eyelids. You get complete blackout with absolute zero pressure — the way a sleep mask should have always worked.
Light suppresses melatonin production even through closed eyelids. The mask eliminates that entirely, protecting the deep sleep window your body needs to complete its overnight repair cycle.
Why total blackout
changes your sleep.
Light is your body's primary signal for wakefulness. Even ambient light reaching the retina — through closed eyelids — suppresses melatonin and keeps your nervous system partially alert.
The pineal gland releases melatonin in response to darkness. Even low-level ambient light — a streetlamp, a charging indicator, a partner's phone — partially suppresses this release and keeps your brain in a lighter sleep stage.
N3 slow-wave sleep — where growth hormone is released and cellular repair happens — requires sustained melatonin. Complete darkness from sleep onset protects this window and extends the time your body spends in deep repair.
When your melatonin wasn't suppressed overnight, the transition from sleep to wakefulness is cleaner. No residual grogginess. No squinting at the alarm. Just a clear, natural wake.
On in seconds.
Works all night.
Set the elastic to a comfortable fit — snug enough to stay in place, never tight enough to create pressure on your head.
Place over your eyes so the 3D dome sits clear of your lashes. You should feel no contact with your eyelids or extensions.
Side, back, or anywhere in between. The contoured design moves with you without shifting, bunching, or losing the seal.
Remove in the morning. No lash damage, no dry eyes, no pressure marks. Just whatever you woke up with, exactly as it was.
