In short. Active infection, inflamed acne, a bleeding disorder, immunosuppression, a keloid tendency or oral acne treatment. What stops this treatment, and for how long.
Key points
- A course asks for several appointments at intervals and for sun protection that continues between them.
- A patient who cannot keep the intervals, or who cannot protect the skin afterwards, is a poor candidate for a reason that has nothing to do with her skin.
- That is worth saying plainly rather than discovering at the third session that the third session is not going to happen.
Every treatment has a list of people it should not be started on, and this one's list is longer than the sales conversation suggests. None of these is a permanent exclusion in most cases. What they are is a reason the plan changes or waits, and a clinic that does not ask about them is not assessing you.
Conditions in the skin itself
Active infection or a cold-sore outbreak in the area. Needling over infected skin spreads the problem and can seed it deeper. Cold sores are the version of this that patients most often fail to mention, because it does not feel like an infection between outbreaks.
Inflamed acne. Active, inflamed acne is being treated for the wrong problem. The treatment also risks making the inflammation worse and, in the worst case, producing new scarring. Control the acne first; then judge what remains.
Active eczema or psoriasis in the treatment area. Skin that is already inflamed responds unpredictably, and the treatment can aggravate the condition. Wait until it is calm.
A keloid tendency. Where a patient forms raised scars after injury, creating fresh injury is a risk that has to be weighed very carefully, and often declined.
Medical history that changes the timing
A bleeding disorder, or anticoagulation that cannot be paused. The channels bleed, and a patient whose clotting is impaired bleeds more, bruises more and heals less predictably.
Immunosuppression. Including some medical conditions and some treatments, this changes both the infection risk and how the skin responds.
Uncontrolled diabetes. Healing is slower and infection risk is higher. Well controlled, it is usually compatible with treatment.
A course of oral treatment for acne that is still running. Some of these treatments make the skin fragile and slow to heal. Nothing is treated until the course has finished and the interval agreed by the prescriber has passed.
The commitment is part of candidacy
A course asks for several appointments at intervals and for sun protection that continues between them. A patient who cannot keep the intervals, or who cannot protect the skin afterwards, is a poor candidate for a reason that has nothing to do with her skin. That is worth saying plainly rather than discovering at the third session that the third session is not going to happen.
Three findings that should stop the plan today
- An active infection, an outbreak of cold sores, or inflamed acne in the area being treated.
- A mark that is new, changing, bleeding or asymmetrical. It is diagnosed first, whatever it turns out to be.
- A pregnancy, or a plan to become pregnant during the course, where the plan has not been discussed with the treating clinician.
Being told to wait is not being turned away. Ask what would have to change, and when it would be reasonable to come back.
Frequently asked questions
Can I have this while I am taking oral treatment for acne?
Usually not until the course has finished. Some oral acne treatments make the skin fragile and slow to heal, and treating it while that is happening risks scarring rather than improving it. The interval after finishing is decided by the prescriber and the treating clinician together, so tell both what you are taking.
I get cold sores. Does that matter?
It does, and it is one of the most commonly missed questions. Needling can trigger an outbreak in someone who carries the virus, and an outbreak on freshly treated skin is a miserable and avoidable complication. It is managed by asking about the history beforehand and sometimes by treatment around the session, so say so at the assessment.
What if I have eczema or psoriasis in the area?
Treating skin that is actively inflamed is a bad idea in both directions: the treatment may worsen the condition and the condition will make the response unpredictable. Wait until the area is calm and stable, and have the skin condition managed on its own terms first.
Risks & Limitations
- Response varies between people and between areas of the same face, and the session count is decided as treatment continues.
- Pigment change can occur in either direction, and the risk is higher in skin that darkens after injury.
- A cold-sore outbreak, infection, bruising or a granuloma can occur, and poor technique or a reused cartridge raises the risk.
- Treating the same area too often or too deeply can worsen texture rather than improve it. No result can be guaranteed.
When to Seek Care
- Spreading redness, increasing pain, fever or discharge after a session — contact the treating team promptly.
- Blistering, a burn-like reaction or a colour change that is spreading rather than settling.
- A mark that is new, changing, bleeding or asymmetrical — assessed as a diagnosis before any treatment.
- Difficulty breathing, chest pain, or a rapidly spreading skin infection — seek emergency care immediately.
