PLUNA or a high-frequency wand?
Short answer
They are easy to confuse because both glow. A high-frequency wand passes a small electrical current through a gas-filled glass electrode held on or just above the skin. PLUNA energizes room air inside its head into cold plasma; the discharge never touches the skin directly, and you glide it over a layer of Booster Gel Serum.
Side by side
| PLUNA | High-frequency wand | |
|---|---|---|
| The light you see | A mode light on the tip: purple, green or red | The gas glowing inside the glass electrode |
| What it uses | Cold plasma: room air energized near skin temperature | A small high-frequency electrical current |
| What touches the skin | A silicone tip. The discharge stays inside the head | The glass electrode |
| Before you start | An even layer of Booster Gel Serum, every time | Varies by device; follow its instructions |
| Session | Timed modes: Face 5 min, Line 3 min, Spot 1 min. It stops on its own | Varies by device |
| Attachments | General, Narrow, and Hair & Body tips | Usually several glass electrode shapes |
High-frequency wands differ from one model to the next, so check the details of any wand you are considering.
Why the gel matters
Plasma works in direct contact with the gel on the skin, so every PLUNA treatment starts with Booster Gel Serum, and you never treat dry skin. PLUNA’s product testing was done with the gel, which is why it is the instructed pairing. Your usual serum or cream comes after.
Where PLUNA comes from
PLUNA grew from 21 years of Korean cold plasma research led by Professor Kim Gyoo-cheon. Its maker, FEAGLE, holds 22 granted Korean patents, and PLUNA won the 2025 Cosmoprof Asia Award for Home and Professional Devices and Tools.
