As hormones shift, your skin rapidly becomes dull, dry, and sensitive. That’s why I recommend Spruka to my patients over 35. It restores hydration, leaving skin visibly lifted and glowing.
SUITABLE FOR: Made for every skin type, even sensitive, dry, or skin that has started losing its bounce. Postpartum and breakout-prone safe.
FEELS LIKE: Cool and grippy the second it touches your face, then weightless, like a second skin. The hush of a high-end facial, in your own bathroom.
HOW IT WORKS: The hydrogel slips its actives into your skin and fades from white to clear as it works. The mask disappears. The glass skin stays.
PERFECT FOR: The night before the reunion. A flat-skin Monday. The weeks the mirror has been winning. Twice a week is all it takes.
FREE FROM: No fragrance, parabens, sulfates, or harsh fillers. Just clean actives, dermatologist-tested.
1. PREP YOUR SKINCleanse your face, then layer on your serum so the actives sink in deeper.
2. APPLY THE MASKPeel off both protective films and press each piece onto your face, top and bottom, smoothing as you go.
3. WEAR ITLeave on for about 60 minutes, until the mask turns fully clear. Your cue to do nothing for once.
4. REMOVE & GLOWPeel it off, pat in the leftover essence, and use twice a week for lasting glass skin.

The 3 Pillars of Glass Skin
Try it risk free
Hydrolyzed Hyaluronic Acid

Hydrate
Galactomyces Ferment Filtrate
The K-beauty ferment legacy, distilled. Refines texture, evens tone, reveals the glass finish.

Why does glass skin take so long?
Between the 10-step influencer routines, 8 hour masks, and the $200+ serums...
There was no fast, convenient, AND affordable way to get glass skin.
And after $57,000+ spent on R&D, dozens of clinical trials, and 3 years of trial and error, we finally discovered the solution...

Not a Mask With Serum. A Serum With a Mask Shape
Other masks are fabric soaked in serum.
Spruka's hydrogel IS the serum, molded solid. As you wear it, the formula moves out of the mask and into your skin.
The mask fades from white to clear. The mask disappears. The glass skin stays.
Glass Skin Without the All-Nighter
Sleep researchers link overnight skincare wear to reduced sleep quality and disrupted rest cycles.
Spruka does in 60 minutes what overnight masks take 8 hours to do.
You get the glass skin without sacrificing your sleep.
Why Hydrogel Masks?
Hydrogel has a clinical origin most beauty brands skip.
It was originally used to treat burns, due to its highly potent formula that heals damaged skin without overwhelming the barrier.
Dermatologists moved the delivery format into cosmetic use decades later. We built on that lineage.
