Plasma pen treatment uses a tiny electrical arc to remove small, benign skin spots like skin tags, cherry angiomas, and milia. Yes, it genuinely works on those, but only on those. It is not a wrinkle eraser and it is not for any spot you have not had checked. Here is exactly what the treatment does, what to realistically expect, and how the at-home version compares to a clinic visit.
This article covers the mechanism in plain language, the step-by-step procedure, an honest by-spot-type efficacy breakdown, the at-home versus in-clinic comparison, safety rules you must read before treating anything, and the healing timeline.
Key takeaways
Plasma pen treatment works very well on small raised benign spots. The at-home version costs a fraction of a clinic session and covers unlimited spots for one price.
- A fine probe tip ionizes air into a plasma arc that lifts raised blemish tissue without cutting the skin.
- It works reliably on skin tags, cherry angiomas, milia, seborrheic keratoses, and small raised age spots.
- It does not work on flat deep pigmentation, large lesions, or any spot that has not been confirmed benign.
- One at-home device handles unlimited spots for a one-time cost versus per-session clinic pricing of $100 to $400+ per area.
- A scab forms the same day and falls off on its own in one to two weeks. Do not pick it.
What plasma pen treatment actually is
A plasma pen never touches your skin. A fine probe tip held just above the surface ionizes the air into a small spark called plasma, and that spark makes tiny controlled contact points on the spot you are targeting. On a raised benign blemish, those contact points dry and lift the tissue so it flakes away over the following days as the skin underneath heals. That is the entire mechanism. It is the at-home version of a tool dermatologists and aestheticians have used for years under names like electrocoagulation and fibroblast treatment.
For a deeper look at the device itself and the science behind the fibroblast mechanism, see our guide on what to expect from a plasma pen procedure.
What happens during a treatment, step by step
The process is short and the same whether you target a skin tag or a cherry angioma.
- Clean the area and, if you want more comfort, apply a numbing cream and wait about 20 to 30 minutes.
- Hold the tip just above the spot and make brief, light contacts. You see tiny dots form on the surface and may notice a faint crackle and a wisp of smoke. This is normal.
- A small scab forms over the next day. Leave it alone.
- Over roughly one to two weeks the scab falls off on its own and fresh skin is underneath.
A single small spot is usually a one to two minute job. Treat lightly on the first session to see how your skin responds before continuing.
Does it actually work? The honest version by spot type
This is the question most pages dodge. Here is the straight answer by spot type.
It works well on raised, benign spots: skin tags, cherry angiomas, milia, seborrheic keratoses, and small raised age spots. These sit on or just above the surface, which is exactly what the plasma arc is designed to lift.
It works less reliably, or not at all, on flat pigmentation deep in the skin, large lesions, and anything requiring it to reach below the surface. It does nothing for a spot that is not actually a benign blemish. A plasma pen is a finishing tool for things you have already identified as harmless, not a diagnosis.
Plasma pen treatment is very good at one job: removing small benign spots you already know are harmless. Ask it to do more than that and you will be disappointed. Ask it to do exactly that and it delivers.
At-home device vs in-clinic treatment
Both use the same underlying method. The real differences are cost, convenience, and who is holding the tool. For a full cost breakdown, see our guide on whether the plasma pen is worth it.
| At-home plasma pen | In-clinic session | |
|---|---|---|
| Typical cost | One-time device purchase | Per session, often $100 to $400+ per area |
| Best for | Small known benign spots, ongoing touch-ups | A spot you want a professional to assess and remove |
| Downtime | A small scab for 1 to 2 weeks | Same healing, same timeline |
| Convenience | On your schedule, unlimited spots | Booked appointments, travel |
| Assessment | You must already know the spot is benign | Professional looks at it first |
For someone with recurring skin tags or a scatter of cherry angiomas they have already had checked, a one-time at-home device pays for itself after a single spot. For a spot you are unsure about, the clinic visit is worth it for the assessment alone.
Safety: read this before you treat anything
Safety callout
Get it checked first. Never use a plasma pen on a spot that is new, changing, bleeding, itching, asymmetric, or multi-colored, or on any mole. Those need a professional eye, not a removal tool. A plasma pen is only for spots a doctor or dermatologist has confirmed are benign and cosmetic. When in doubt, leave it and book a skin check. See guidance from the American Academy of Dermatology on when to see a dermatologist for skin growths.
Beyond that, keep treatments light, do not pick the scab, keep the area clean, and protect the new skin from the sun while it heals. For the full safety picture, see our guide on what makes the plasma pen procedure safe.
Aftercare and the healing timeline
The four-phase window after every treatment. Following it gives the skin the best chance to heal clean with no marking.
Day 1-7
Leave it alone
Do not pick. Let the scab do its job as the skin underneath heals.
Week 2 onward
Skin renewed
Daily SPF 50. New skin burns easily. See the NIH MedlinePlus note on UV protection during healing.
(The Advanced Numbing Cream, Healing Patches, Skin Therapy Recovery Cream, and SPF 50 are available together in the Ocura Ultimate Bundle. They are not included with the base pen.)

The bottom line
Plasma pen treatment is a proven at-home method for removing small, raised, benign spots. It works best on skin tags, cherry angiomas, milia, and similar surface-level blemishes. The healing process is predictable: a scab forms the same day, falls off in one to two weeks, and fresh skin appears. For anything undiagnosed or changing, see a professional first. For confirmed benign spots, the at-home route is the simplest and most cost-effective way to remove them.
