Plasma pen on the eyelids: what "non-surgical blepharoplasty" does, the burn, pigment and scar risks, and who should not

A plasma pen is sold as a way to tighten loose eyelid skin without an operation, often under the name "non-surgical blepharoplasty" (blepharoplasty is the medical name for eyelid surgery). The pitch is simple and the device is real. What is less often said is how it works, how small the published evidence for eyelids is, and what a burn, a pigment change or a scar on a lid can mean. This article sets out all three, and then what loose skin, a heavy brow and a true droopy lid each actually need.

What does a plasma pen do to the eyelid?

It makes tiny, controlled burns on the surface of the skin. Health Canada describes a plasma pen as a device that focuses electricity on the skin surface and causes a controlled burn, and notes that these devices are marketed for eyelid lifts and wrinkle reduction.

The idea is that a pattern of small surface injuries is followed by healing, and that the skin contracts as it heals. The device is sometimes called a "fibroblast" pen, after the cells that lay down collagen during repair. Note what that means: the treatment works by wounding the skin and relying on the repair. It does not lift the brow, it does not touch the muscle that raises the lid, and it does not remove skin.

Not every "plasma" device is the same. A hand-held pen, a microplasma applicator and a nitrogen plasma unit differ in power, in how the energy is controlled and in how much has been studied. The papers below involve medical devices used in research settings, which is not the same as a pen bought online.

What does the published evidence for eyelid skin actually show?

Small studies, short follow-up and mostly mild cases. That is the honest summary, and it is worth reading the details.

One trial treated 40 women with loose upper-lid skin (dermatochalasis, the medical name for excess eyelid skin) using plasma exeresis, three sessions a month apart. Two dermatologists and two ophthalmologists who did not know which photographs were which scored the lids three months after the last session. Lid laxity on a rating scale improved, with 36 of the 40 (90%) showing a change and 4 showing none, and the marginal crease distance increased. The authors reported no serious adverse events and concluded the method could suit mild and moderate cases.

A second, open-access study used an ablative radiofrequency microplasma device on 21 eyes of women aged 45 to 67, with photo skin types I to IV. How much it helped depended on how much skin there was to begin with. Among the 10 mildest eyes, 9 were judged to have significant improvement. Among the 7 with severe excess skin, 1 was (14.3%). The authors concluded it may suit mild loose skin and that for more advanced grades surgery gives better results.

Three things limit all of this. The groups are small and the follow-up is weeks to a few months, so nothing here says how long a change lasts. The device in each paper is a specific medical-grade system, so the results do not transfer to any pen. And the improvement is measured as a change in how much skin overhangs, not as a change in the position of the lid or the brow, which is what a heavy-looking eye often depends on.

A randomised trial of nitrogen plasma near the eye, in 18 volunteers in Bangkok, treated wrinkles around the eye with an untreated side as a comparison. It is evidence about fine lines, not about lid laxity, and it is included here mainly for what it reported about side effects.

What are the burn, pigment and scar risks?

Health Canada lists pain, swelling, redness, sagging skin (particularly in the upper eyelids) and hyperpigmentation, meaning darker patches, among the effects of plasma pens even when they are used as intended. It lists skin punctures from the needle tip, excessive burns from overuse or prolonged use, and burns to the eye as risks of improper use. Its alert adds that the likelihood and severity of side effects rise with the duration, frequency and intensity of treatment.

Pigment matters most for Malaysian skin. In the Bangkok trial the short-term effects included redness, scaling, itch, dryness and temporary hyperpigmentation, and the authors say they chose the device partly because of the higher skin types, such as those of Thai patients. Paler patches, hypopigmentation, are the opposite change, and the papers read for this article do not report on them. None of them measured pigment change by skin type for the eyelid, so no figure can be quoted for how likely it is in a given person.

Scarring is the risk that cannot be walked back. A burn deep enough to destroy the skin's lower layers heals as a scar, and on a lid, scar tissue pulls. The eyelid skin is among the thinnest on the body, and that is the reason a treatment that is mild elsewhere on the face can be less forgiving here. Any open surface wound can also become infected.

The eye itself is the other concern. A published case report from Dundee describes a woman who had plasma fibroblast skin tightening at a salon and arrived at hospital four hours later with severe pain in both eyes, light sensitivity and reduced vision. She had alkali chemical injuries with corneal epithelial loss, thought to be from numbing cream that had got into both eyes during preparation. She recovered satisfactorily with treatment. The injury was not from the arc at all, which is the point: the hazards of working near the eye include everything done around the device, not only the device.

Who should not have plasma treatment on the eyelids?

The papers do not give one agreed list, but they do show where the researchers drew their own lines. The microplasma study enrolled only photo skin types I to IV and excluded people whose ptosis was caused by a muscle or nerve problem, people with possible impaired wound healing and people with compromised skin integrity.

That points to the groups who need an individual assessment first, and in many cases a clear answer of no. People with darker skin types, who are more prone to pigment change, are one such group. A skin type IV cut-off in a study is also a reminder that the evidence was not gathered in people with the deepest skin tones. Active infection or an inflamed skin condition at the site is another. So is a history of poor healing or heavy scarring. Medicines that change healing or skin sensitivity are the sort of thing any doctor asks about before a treatment that injures skin; this is a general principle, not a finding from the papers cited here.

Equally important is who should not be treated for the wrong reason. If the problem is a lid that has dropped because the lifting muscle has weakened, or a brow that has descended, an arc on the skin is aimed at the wrong structure. A sore, swollen or changing lid also needs a diagnosis before anything is burned.

What changes when the device is bought online or the operator is untrained?

The risks above are the risks with a controlled setting. Health Canada's alert warned against unauthorised plasma pens used at spas and by estheticians, and noted that harm rises with duration, frequency and intensity, which are exactly the settings a trained operator controls and a home user may not. An update to the alert said that certain plasma pens were then authorised for use by healthcare professionals only.

The general rule is firm. In Malaysia a medical device supplied here must be registered under the Medical Device Act 2012, and the public register can be searched. The Retreat Clinic's explainer on the Medical Device Order 2026 and how to check a device's registration shows how that search works; it concerns lasers and HIFU, so it does not say whether any particular pen is registered. The questions it raises, who is operating the device and whether the device is registered, are worth asking of any energy treatment near the eye.

What do loose skin, a heavy brow and a true droopy lid each need?

Three different problems can make an upper lid look heavy, and each has a different fix. Loose skin is a skin problem. A heavy brow is a position problem. A droopy lid, ptosis, is a muscle problem. A plasma pen can only ever be aimed at the first.

Excess skin hanging over the lid margin is what upper blepharoplasty removes, and my guide to upper blepharoplasty in Kuala Lumpur sets out what that operation involves. When the brow has sagged, it pushes skin down onto the lid, and tightening the skin below does not raise it; brow ptosis versus eyelid ptosis explains the difference, and how surgeons tell a hooded lid, ptosis and a heavy brow apart shows what is being checked. When the lid margin itself sits low, the levator (the muscle that lifts the lid) is the target, which is the subject of my piece on droopy eyelids without surgery.

The microplasma study makes the same point in its own way: it excluded muscular and neurological ptosis, and found the benefit shrank as the excess skin grew. The full range of options, from creams to devices to injections, is laid out in non-surgical eyelid rejuvenation: what it can and cannot do.

If you are weighing a plasma treatment, the useful first step is a diagnosis: which of the three is it, and how mild? That decides whether any non-surgical option fits. More on the area is in periorbital aesthetics, the eyelid conditions section and my hub article on why eyes look tired.
