The science
Meet cold plasma.
Plasma sounds like something that ought to be hot. Staying cool is the whole point of this one. Cold plasma is the fourth state of matter, air that has been energized rather than heated, and it is gentle enough to hold against your skin for five minutes a day.
The mechanism
Cold plasma doesn't damage the skin.
It signals it.
PLUNA delivers energy to the skin, creates reactive signals, activates cellular activity and supports renewal.
Why this needed solving
Every technology strong enough to change how skin looks has historically asked for something first. Heat. A wound. Time off afterwards. The compromise was treated as the price of the result. Cold plasma does not ask for it, and the reason is in the physics rather than in the dose.
01Deliver energy
Energized air meets the treatment surface directly.
02Create signals
Short-lived, charged molecules form at the skin surface.
03Activate
Cellular activity is prompted rather than injured.
04Support renewal
The skin does its own work, supported.
The consumer takeaway
Stronger-looking barrier support, better hydration, smoother-looking texture and improved topical performance.
U-Turn technology
Optimized plasma flow for
gentle, efficient skin activation.
PLUNA's patented U-Turn pathway recirculates and controls plasma inside the head, helping create a dense, steady output across the treatment surface.
U-Turn pathway
The flow turns back on itself inside the head rather than passing straight through, which is what the technology is named for.
Across the treatment surface
Output is distributed across the surface the tip is held against, not concentrated at one point.
Direct contact
The open tip removes the screen found on many plasma devices, so plasma meets the treatment surface directly.

The contrast
No heat. No wounding.
No downtime.
Many aesthetic technologies intentionally create controlled injury and then rely on recovery. Cold plasma is designed to work without heat-based injury.
Injury and recovery
Energy is used to create a controlled wound. The visible result arrives through the healing that follows, which is why recovery time is part of the treatment.
Signalling
Energy is used to prompt activity in skin that is not injured. There is nothing to recover from, which is what makes a daily five-minute routine possible.
NoZone Cold Plasma®
Cool enough
for every day.
A dielectric barrier turns the air at the tip into cold plasma. No heat and no electrical current go into the skin. A filter strips the byproducts, so it is comfortable to use every single day.
No heat, no current
Plasma meets the skin cool. The treatment does not work by heating tissue, so there is no thermal injury to recover from.
Runs on air
Fed by air alone. No cylinder, no refills, and a filter that strips the byproducts.
Opens a short window
For a short time, what you apply next gets past the surface. Then the window closes on its own.
What it is for
PLUNA is intended to help manage skin condition: to help soothe the skin and maintain a healthy complexion.

Cold plasma physicist
“Cold plasma is not a tool. It is a category of physics. The job of the device is to deliver it faithfully.”
21 years at the leading edge of cold atmospheric plasma research. His laboratory is where the science behind PLUNA was written, and the peer-reviewed research and registered IP behind the platform are its work, engineered for home by FEAGLE.

The science
The charts, as published.
PLUNA's own measurements for the device and for Nano Gold Gel. Tap any chart to read it in full.
Device: 20 adults aged 35 to 60, one session. Gel: 22 adults aged 19 to 59, one application. Individual results vary and depend on consistency of use.
Built for daily use
Four things the
platform is built on.
True cold plasma, ultra-low ozone engineering, measurement at the handpiece, and a treatment that changes to suit the area rather than the other way round.
Safety
Engineered for ultra-low ozone emissions, and measured at the handpiece: the point that actually meets your skin.
The technology
Plasma generated by PLUNA’s own patented method. Twenty-two granted Korean patents sit behind the platform.
Absorption
Cold plasma works near skin temperature and helps the skincare you already use further in. Nothing about it stings.
Customizing
Three modes and three tips. The treatment changes to match the area and the skin. The routine does not.
Patent count is granted Korean registrations; PCT entries are international applications and are counted separately on the technical information below. Source and regulatory footnotes are published with the final Instructions for Use.

Categories, not brands. The point is the shape of the trade, not a scoreboard.
| Measure | PLUNA | In-clinic energy devices | Most home devices |
|---|---|---|---|
| Heat | None | Often central to the mechanism | Varies by device |
| Downtime | None to plan | Commonly some | Usually none |
| Consumable gas | None, fed by air | Often a cylinder | Not applicable |
| Where | At home | An appointment | At home |
| Session | Five minutes | Scheduled around | Varies by device |
| Open tip | Yes | Varies | Typically screened |

Still wondering
Does PLUNA get hot?
PLUNA is designed around cold plasma operating near skin temperature rather than a heat-based treatment.
How often should I use PLUNA?
Face Mode is designed as a five-minute daily treatment.
Do I need Nano Gold Gel?
Yes. Apply an even layer of Nano Gold Gel to the treatment area before using PLUNA. The source materials instruct users not to treat dry skin.
