WHY IT WORKS
5
Reasons people
seal every night.
-
24-hour sealed hydration
Marine collagen + hyaluronic acid pulled deep into the skin, locked in by a thin breathable barrier.
-
Glass-smooth by morning
Smooths surface texture and reflects light — the look you usually need filters for.
-
Anti-aging over time
Niacinamide 5% + peptides strengthen the barrier and improve elasticity with daily nightly use.
-
No pillow transfer
Dries to a soft, invisible film. Sleeps on any pillow, washes off any sheet.
-
Two minutes — that's all
Apply with the included applicator. Brush on. Sleep. The mask does the rest.

What gets sealed in,
night after night.
PLUMPING
Marine Collagen
Low-molecular-weight peptides absorb overnight to firm and plump from within.
SEALING
Polyglutamic Acid
Forms a soft, invisible film that locks moisture in for 8+ hours of barrier support.
BRIGHTENING
Niacinamide 5%
Refines tone, smooths surface, strengthens the lipid barrier over weeks of nightly use.
CALMING
Centella + Allantoin
A soothing duo for reactive skin and night-time redness — calms while it seals.
HOW IT WORKS
Four steps,
then sleep.
1
Cleanse + tone
Wash with a gentle cleanser, follow with your usual toner. The mask needs a clean canvas.
2
Apply a thin layer
Using the included applicator, brush on a thin even layer across face, neck, jawline.
3
Wait 60 seconds
Let it dry to a soft film. It won't tighten — just sets gently. No tugging, no shine.
4
Sleep · wake glow
Sleep with it on. Rinse with cool water in the morning. Skin: sealed, smooth, ready.

Everything you're quietly wondering.

How often should I use it?
Every night, or 4–5 nights a week. Daily nightly use gives the best results over 28 days.

Will it transfer onto my pillow?
No. It dries to a soft, invisible film in about 60 seconds. Sleep on any pillow, any fabric.
-
Can I use it with retinol?
Yes — apply retinol first, wait 5 minutes, then layer the sealing mask on top. It locks the actives in.

How long does one tube last?
