Does at-home cold plasma work?
Short answer
Here is what has been measured. In a 2024 study, 20 adults used PLUNA once, and instrument readings for redness, elasticity, wrinkle roughness and inner skin moisture all changed straight afterwards. It was a single session with no control group, so it shows small, consistent changes, not a promise. Individual results vary and depend on consistency of use.
What was measured
True Skin Clinical Trial Center, 21 June 2024. 20 adults aged 35 to 60, measured by instrument before and straight after one PLUNA session.
| Reading | Before | After | Change |
|---|---|---|---|
| Redness index | 18.81 | 17.89 | 4.93% less redness |
| Elasticity (cheek) | 0.559 | 0.582 | 4.08% more elastic |
| Eye wrinkle roughness | 8.4 | 7.3 | 13.17% smoother |
| Nasolabial fold roughness | 7.64 | 6.61 | 13.45% smoother |
| Inner skin moisture, 2.5 mm | 26.85 | 30.00 | 11.76% more moisture |
Roughness was read from a skin replica, and moisture 2.5 millimetres below the surface, not on it. The charts, with how to read each one, are on Why PLUNA Cold Plasma.
What this shows, and what it does not
- It shows small, consistent changes in instrument readings after a single use.
- It does not show results over weeks. The study measured one session.
- There was no control group, so the readings were not compared with people who did not use PLUNA.
- Everyone is different. Individual results vary and depend on consistency of use.
What the lab research covers
A peer-reviewed 2026 laboratory study, funded by the manufacturer, looked at the same no-ozone cold plasma on human skin cells (keratinocytes) in a dish. It describes the technology in cells, not results in people who used PLUNA.
PLUNA’s maker, FEAGLE, also publishes wider research: 60 papers, 14 of them skin-related. Most of that work studies plasma for other uses, so it is not evidence about PLUNA at home.
What builds a visible difference
PLUNA is designed around five minutes of Face Mode every day, starting with Booster Gel Serum. Day 5 reflects the point at which visible change may begin with recommended daily use. It is not a guarantee.
