In short. Pigment change is the risk that decides the indication, particularly in skin that tans readily. What else can be considered for laxity, and what none of it can do.
Key points
- It is paying the discomfort, the redness and the days of healing and getting a change too small to justify them.
- That is not a medical complication.
- It is the predictable outcome of asking a surface treatment to solve a problem of position, and it is why the boundary of the indication matters more than the result.
Pigment change is the risk that decides whether plasma treatment suits a particular patient, and it deserves more space than the procedure itself. Any resurfacing injury can leave the treated skin darker than it was, or in some cases lighter, and both are harder to correct than to avoid.
Why pigment risk dominates
Skin that tans readily, skin that has marked after a previous injury or infection, and skin with an active pigment condition all carry more of this risk. The change may settle over months and may not settle completely, and treating it again is often the wrong response, because a further injury can deepen the problem. This is why an assessment begins with the skin rather than the device, and why a small test area first is reasonable rather than a delay.
The other risks
The remaining risks are the ordinary risks of a wound: infection, delayed healing, and a scar that heals thickly or spreads. The pinpoint marks left by hand-held instruments can take a week or two to fade, and redness lasts several days. Treatment close to the eye carries its own concerns: eyelid skin is thin and the eye lies immediately behind it.
The commonest disappointment is not a complication
It is paying the discomfort, the redness and the days of healing and getting a change too small to justify them. That is not a medical complication. It is the predictable outcome of asking a surface treatment to solve a problem of position, and it is why the boundary of the indication matters more than the result.
What else can be considered
Where the target is surface quality, the alternatives are topical care, chemical peeling and the resurfacing family. Fractional laser resurfacing, radiofrequency microneedling and microfocused ultrasound each reach different depths and each has a longer and larger published record than plasma treatment does. Where two of them would address the same finding, the one with the longer record is the more honest starting point.
Where the target is looseness of the skin, the same list applies with the same caveat: a surface treatment reaches only the skin. Where tissue has descended, or there is skin to remove rather than skin to tighten, an operation addresses what the devices cannot. Where the finding is volume loss, no tightening option answers it, because tightening an area that has lost volume changes firmness rather than shape. Where the finding is an active pigment condition, the treatment is medical, not device-based.
Doing nothing
Doing nothing remains a real option, and it carries no pigment risk. Skin quality changes slowly, and an appearance that troubles you today may be stable rather than worsening. Waiting costs nothing and makes every decision taken afterwards better informed.
Seek care if
- Blistering, spreading redness, warmth or pus in a treated area — that suggests infection and needs assessment.
- A treated area that heals darker or lighter than the surrounding skin — have it assessed rather than treated again.
- Any treatment near the eye followed by pain, a change in vision or a lid that will not close — seek emergency care immediately.
Frequently asked questions
Why is pigment change the main risk?
Because it is common, it is caused by the treatment itself rather than by error, and it is harder to correct than to avoid. Any resurfacing injury can leave treated skin darker or lighter, and the risk is higher in skin that tans readily or has marked after a previous injury. Treating the change again is often the wrong response, because another injury can deepen it.
What can be done for loose skin without surgery?
Energy-based tightening treats the skin and can produce modest improvement, with a result that is not guaranteed and is smaller than an operation. Where there is significant excess skin, or tissue that has descended, a device does not remove skin or reposition tissue, and surgery is the option that addresses what the devices cannot.
Is doing nothing a reasonable choice?
Yes, and it is often the first sensible one. Skin quality changes slowly, an appearance that troubles you today may be stable rather than worsening, and waiting carries no pigment risk and costs nothing. Any decision taken afterwards is better informed for the wait.
Risks & Limitations
- Plasma treatment acts on the surface of the skin. Tightening the skin is not a lift and does not reposition tissue that has descended.
- Pigment change is the central risk. Any resurfacing injury can leave treated skin darker or lighter, and the risk is higher in skin that tans readily or marks after injury.
- The change may settle over months and may not settle completely.
- New collagen forms as part of healing, but the amount formed is not established as enough to change the position of the face.
- Infection, delayed healing and a scar that heals thickly or spreads are the ordinary risks of any wound.
- The most common disappointing outcome is not a complication: it is days of healing for a change too small to be worth them.

When to Seek Care
- After a resurfacing treatment, blistering, spreading redness, warmth or pus suggests infection and needs assessment.
- A treated area that is becoming more painful rather than less, or a wound that is not closing on the expected course, needs review.
- Any treatment close to the eye that leaves pain, a change in vision or a lid that will not close — seek emergency care immediately.
- A treated area that heals darker or lighter than the surrounding skin should be assessed rather than treated again.
- A fever, or a rash spreading beyond the treated area, needs medical assessment rather than cosmetic advice.
