In short. The signs that should not wait for a routine review after RF microneedling, how to route yourself to the right service, and what to say when you get there.
Key points
- With an energy injury, the difference between a good and a poor outcome is usually time rather than treatment.
- That is why the routing is written as a sequence, and why the red flags at the top of this site bypass it entirely and go straight to the last step.
Most of this site is about telling ordinary healing from a problem. This page is about the step after that: what to do when you have decided something is wrong, and how to get to the right place without losing time.
Route one: your treating team
For anything that is not immediately dangerous, the treating team is the right first call. They know what was done, at what depth, on what date and with what aftercare, and that is what the judgement depends on.
Route two: the hospital main line
If your treating team cannot be reached, the hospital can route you to the service that can help. It is not a lesser option; it is the same building and the same record. The contact page explains the channels, and the reason this site publishes no emergency number of its own is that a number printed on a website can be wrong at the moment it matters most.
The order of the calls is the whole point
With an energy injury, the difference between a good and a poor outcome is usually time rather than treatment. That is why the routing is written as a sequence, and why the red flags at the top of this site bypass it entirely and go straight to the last step.
Route three: the nearest emergency department
Some findings do not wait for a reply from anyone. Blistering, or skin turning white, grey or leathery over a treated area, is a burn and is treated as an emergency. Spreading redness with heat, pus, fever or a foul smell is an infection that moves faster than most people expect. Any change in vision, or severe eye pain after treatment near the eyes, is an emergency in its own right. Go, and do not wait.
What to say when you arrive
One sentence carries most of the value: that you had radiofrequency microneedling, on what date, to which area. Then what you have noticed, when it started, and what you have applied since. Bring any record you were given, your medication list, and photographs taken over the previous days, because a burn is judged by how the appearance has evolved rather than by a single moment.
What urgent care cannot tell you
An emergency assessment answers one question: whether there is something that needs treating now. It will not say what the skin will look like in six months, because nobody can know that, and it will not plan later treatment. That belongs to a review once the acute problem has been dealt with. What matters in the urgent setting is that nothing dangerous is missed, and being told that nothing dangerous is happening is a good outcome.
Go to the nearest emergency department now if
- Skin over a treated area is blistering, or turning white, grey or leathery.
- There is spreading redness, heat, pus, fever or a foul smell from the skin.
- There is any change in vision, or severe eye pain, after treatment near the eyes.
Frequently asked questions
Who should I call first if something is wrong?
Your treating team, because they know what was done to your skin and when. If the team cannot be reached, call the hospital main line. If the finding is a burn, a spreading infection or an eye symptom, skip both and go to the nearest emergency department immediately.
What should I say when I arrive?
That you had radiofrequency microneedling, the date, the area treated, and what you have noticed and when it started. Say what you have applied to the skin since. That single sentence about the treatment is what tells the clinician what kind of injury to look for.
Can I wait until morning if it is late at night?
For blistering, skin turning white or grey, spreading redness with fever, or any change in vision or severe eye pain, no. These are the findings where a delay of hours changes what can be done. For a stable colour change or a lump under healed skin, waiting for a review is reasonable.
Risks & Limitations
- A burn, where heat delivered at depth injures the skin more than intended. Blistering, or skin turning white, grey or leathery, needs immediate assessment.
- Infection, which moves faster than most people expect and is treated rather than observed.
- Pigment change. Darkening often settles over months; loss of pigment may not recover, and no treatment reliably restores it.
- Scarring, including a lump, ridge or raised scar forming under skin that looked healed.
- A herpes outbreak reactivated by treatment, which needs same-day care because an untreated outbreak can scar.
- Contour change, where heat delivered at depth has affected the fat beneath the skin rather than its surface.
- A result that cannot be judged in the first month, because collagen change is gradual.
When to Seek Care
- Blistering, or skin turning white, grey or leathery over a treated area — a burn until assessed otherwise; seek emergency care now.
- Spreading redness, heat, pus, fever or a foul smell from the treated skin — seek emergency care now.
- Any change in vision, or severe eye pain, after treatment near the eyes — seek emergency care now.
- Pain that keeps worsening after the first two days instead of settling, or a painful cluster of blisters on the face — seek care the same day.
- Skin that has turned darker, lighter or white in patches and is not recovering, or a hard lump or ridge forming under the skin — have it assessed at a review.
