Cold atmospheric plasma is an emerging technology in skin science. In an aesthetic clinic, its value depends on the specific device, its authorized intended use, the clinician’s training, and a well-defined treatment protocol. This guide explains the technology in plain language and offers a responsible workflow for evaluating it in practice.
Evidence in context: Published dermatology research covers several different plasma sources and treatment methods. Results from one device or research protocol should not be assumed to apply to every cold plasma machine or to every aesthetic indication.
What is cold atmospheric plasma?
Plasma is often described as the fourth state of matter. Cold atmospheric plasma is a partially ionized gas generated near room temperature and atmospheric pressure. Depending on the source and settings, it can contain short-lived reactive oxygen and nitrogen species, charged particles, and other physical components that interact with a surface.
In dermatology research, both direct application and indirect approaches—such as plasma-treated liquids—have been studied. These approaches are not interchangeable. The energy source, gas, distance, exposure time, treatment area, and device design all affect what is delivered.
For that reason, “cold plasma” is not a single standardized treatment. A clinic should follow the specific device instructions for use (IFU) and avoid transferring a protocol from a study unless the device and method genuinely match.
Potential applications in aesthetic clinics
Research and clinical use are developing at different speeds. A systematic review of dermatology studies found a broad range of plasma sources and applications, with much of the published work focused on wound healing and other medical dermatology questions. That landscape supports careful interest—not blanket claims for cosmetic outcomes.
Adjunctive skin protocols
Some clinics explore cold plasma as an adjunct within a broader skin-care plan. Any use should stay within the device’s intended purpose and the practitioner’s professional scope.
Scalp wellness services
Scalp applications are an emerging area. A consultation should first distinguish cosmetic scalp care from hair loss that needs medical assessment.
Evidence-aware protocols
Published findings can help frame questions for clinicians, but a study protocol is not a substitute for a manufacturer’s validated operating instructions.
Clear expectations
Explain what the device is intended to do, what is still being researched, and what outcomes cannot be promised before treatment begins.
Potential benefits for clinic operations
When a device is appropriate for the clinic and used according to its instructions, cold plasma may offer operational qualities that practitioners find useful. These are workflow considerations, not guaranteed patient outcomes.
| Clinic consideration | What to evaluate |
|---|---|
| Non-thermal approach | Confirm the device’s treatment mechanism and whether the intended protocol is non-thermal at the tissue level. “Cold” does not remove the need for precautions. |
| Service fit | Assess whether the device complements existing services and whether staff can explain its purpose without overstating evidence. |
| Training and repeatability | Review onboarding, settings, treatment distance, exposure time, cleaning, and documentation procedures. |
| Client experience | Set expectations for sensation, session length, aftercare, and follow-up using the device-specific IFU. |
Scalp care and hair restoration treatments
Interest in cold plasma for scalp care and hair restoration is growing, but the evidence base remains early and device-specific. Hair loss has many possible causes—including genetic, hormonal, inflammatory, nutritional, and medication-related factors—so the first step is an appropriate clinical assessment rather than assuming one treatment fits every client.
A small 2020 pilot study examined the tolerability of an indirect cold-plasma approach using plasma-activated medium in people with androgenetic alopecia. The study’s primary aim was tolerability, not proof of efficacy; its authors called for larger, longer studies. A 2025 nonrandomized controlled study on a cold atmospheric plasma device and hair growth has also been published, but its PubMed record does not provide an abstract, so detailed results cannot be assessed from that record alone.
These reports are not evidence that every direct-application aesthetic device produces hair regrowth. The method, device, study design, patient group, and measured outcomes matter. Clinics should present CAP as an area of ongoing investigation and refer clients with sudden, patchy, painful, or progressive hair loss for medical evaluation.

A responsible cold plasma treatment workflow
A consistent workflow helps staff communicate clearly, follow device instructions, and document each session. Adapt every step to the specific equipment and local requirements.
-
Consult and screenClarify the client’s goals, review relevant history, assess the treatment area, and identify concerns that require referral or a different care pathway.
-
Confirm the device and indicationCheck the model, intended use, local authorization, contraindications, and current manufacturer instructions before scheduling treatment.
-
Set a baselineRecord the starting condition using consistent notes and, where appropriate and consented, standardized photographs. Do not promise an outcome.
-
Prepare the treatment areaFollow the IFU for cleansing, positioning, eye protection, consumables, gas supply, and any other device-specific preparation.
-
Deliver the protocolUse only the parameters, distance, movement, and exposure schedule specified for that device and indication. Do not improvise settings.
-
Observe and documentMonitor comfort and the skin or scalp response during treatment. Record settings, duration, observations, and any interruption or adverse response.
-
Give aftercare and follow upProvide written, device-appropriate aftercare and agree on a review plan. Reassess before any repeat session.
Safety, patient selection and responsible claims
Cold plasma systems differ in their energy source and operation. A clinician should be trained on the exact model and should not assume that a low-temperature process is risk-free. Use the manufacturer’s current instructions, maintain the device as specified, and follow local professional and regulatory rules.
- Use the device only for its stated intended purpose and treatment sites.
- Screen the client and treatment area against the manufacturer’s contraindications and precautions.
- Do not apply over a compromised or symptomatic area unless the device instructions and a qualified clinician specifically support that use.
- Pause and reassess if unexpected discomfort, irritation, or another concerning response occurs.
- Keep treatment records and explain the limits of current evidence, especially for hair restoration.
For hair concerns, a licensed medical professional can help identify the cause and discuss established options. Cold plasma should not replace a diagnosis or delay appropriate care.
Frequently asked questions
Is cold plasma treatment the same as a plasma pen?
No. The term “plasma” is used for different technologies. Cold atmospheric plasma systems and cosmetic plasma pens can differ substantially in how they generate energy and interact with tissue. Confirm the device type and follow its own instructions.
Can cold plasma regrow hair?
Current research is promising enough to justify further study, but it does not support a universal promise of hair regrowth. Published scalp work includes small or nonrandomized studies and uses specific plasma methods; results may not apply to another device.
How many cold plasma sessions are needed?
There is no single schedule for every device or indication. Use the manufacturer’s protocol and the treating clinician’s assessment rather than applying a generic session count.
Can any aesthetic clinic offer cold plasma?
That depends on the device’s regulatory status, intended use, local rules, and the practitioner’s qualifications. Clinics should verify each of these points before offering treatment.
