In short. Dissolving is decided by an assessment rather than by a request. Why the substance class comes first, what the examination establishes, and what follows.
Key points
- That single sentence settles a large share of consultations.
- If filler was placed to disguise a structural hollow, dissolving restores the hollow.
- If it was placed to change a contour the bone determines, dissolving returns the original contour.
Dissolving looks like a simple request and behaves like a treatment, which is why it begins with an assessment rather than an appointment. The assessment answers four questions, and the first of them determines whether the other three are even relevant.
What was injected
The substance class, the areas treated, the date, and how many previous injections have been performed in the same place. This comes first because it decides whether dissolving is available at all: hyaluronic-acid filler can be dissolved with an enzyme, and calcium hydroxylapatite, poly-L-lactic acid and polynucleotides cannot. Where the product is unknown, it is recorded as unknown, and the plan proceeds on the basis that dissolving may not work — with a first measured dose serving as information as well as treatment.
What the problem actually is
A patient who dislikes the amount of filler has one problem. A patient with a nodule, an asymmetry, a vascular complication or an infection has another, and each changes the urgency and the order of treatment. So does a patient whose real concern is a contour or a hollow that the filler was placed to camouflage — because removing the filler returns that contour rather than changing it.
Dissolving removes material; it does not remove the reason for it
That single sentence settles a large share of consultations. If filler was placed to disguise a structural hollow, dissolving restores the hollow. If it was placed to change a contour the bone determines, dissolving returns the original contour. The question is not only whether it can be removed but what is underneath.
What the examination establishes
What is present and where it sits, how much of it there appears to be, how the tissue around it looks, and whether there is something else going on — a nodule, an inflammatory reaction, an infection — which would change the order in which things are treated. Photographs are taken for the record, because the change after dissolving happens over days and weeks and is judged more reliably from a series of images than from memory.
What the plan should answer
Whether dissolving applies to your material. How much will be used, and in how many sessions. What the area is expected to look like in between, including the possibility that it will look hollow if a large volume is removed. When any further treatment would be considered. And what the limits are: that dissolving does not restore a previous appearance, that it may not remove everything, and that it carries the risks of any injection.
What you should leave with
Clear answers to those questions, and an honest statement of what cannot be promised. A patient who understands that the face afterwards will be the face as it is now without the filler — rather than as it was before the filler — is the one who judges the result realistically.
Seek care rather than waiting if
- Pain is severe out of proportion to an injection, or the skin turns white, grey, mottled or dusky — a vascular emergency; contact your treating team now, and if the team cannot be reached go to the nearest emergency department immediately.
- Any change in vision — seek emergency care immediately.
- A fever, spreading redness, heat or pus at an injection site, or a rash spreading beyond the treated area.
Frequently asked questions
Why can I not just book dissolving?
Because whether it is possible depends on what was injected, and whether it is appropriate depends on what the problem actually is. A patient who dislikes the underlying shape rather than the filler would not be helped by removing it, and a patient with a non-dissolvable material would not be helped either.
What if I was injected elsewhere and have no records?
You can still be assessed. Bring whatever you have, say where and when the injection was performed, and say what you know about the product. A tertiary hospital assesses complications and requests after treatment performed elsewhere routinely.
Will I need tests before dissolving?
Usually not. The assessment is mainly history and examination, with photographs for the record. Tests are used where a specific question needs answering, such as whether there is an infection or whether a lump is a collection rather than product.
Risks & Limitations
- A dissolving agent works on hyaluronic-acid filler only. Calcium hydroxylapatite, poly-L-lactic acid and polynucleotides cannot be dissolved.
- Vascular occlusion — filler blocking a blood vessel — is a time-critical emergency that can cause skin loss and, rarely, vision loss.
- Dissolving is not risk-free: it can cause an allergic or inflammatory reaction, bruising or swelling.
- Too much dissolving agent can remove your own hyaluronic acid as well as the filler, changing volume and skin quality.
- A filler whose identity is unknown cannot be assumed to be dissolvable.
- The result after dissolving is not a return to a former appearance; it is the face as it is now, without the filler.
- No outcome can be guaranteed, and more than one session may be needed.
When to Seek Care
- Severe pain, or skin turning white, grey, mottled or dusky after an injection — a vascular emergency; contact your treating team now, and if the team cannot be reached go to the nearest emergency department immediately.
- Any change in vision — seek emergency care immediately.
- Fever, spreading redness, warmth or pus at an injection site.
- Increasing swelling, a hard painful lump, or a rash and itching that spreads after dissolving.
- Blistering or skin breakdown over a treated area.
