In short. Dissolving is a treatment rather than a correction of one: its vascular risk, allergic reactions, bruising and the removal of your own tissue gel.
Key points
- The enzyme breaks down hyaluronic acid wherever it finds it.
- Injected filler is the intended target, and your own tissue contains the same substance.
- That is why too much at once can leave an area hollow or deflated, and why the amount used is a deliberate decision rather than a calculation.
Patients tend to think of dissolving as the correction of a treatment rather than as a treatment in its own right, and it is worth being clear that it is the second. It involves an injection into facial tissue, with the risks that involves, and it has consequences that the filler did not have.
The risks of the injection
Vascular occlusion — material in a blood vessel, starving the tissue it supplies of blood. It is a time-critical emergency that can cause skin loss and, rarely, vision loss, and the outcome depends on how fast it is recognised. Severe pain out of proportion to the injection, or skin turning white, grey, mottled or dusky, requires immediate assessment; any change in vision requires emergency care immediately. Beyond that: bruising, swelling, tenderness, and the possibility of infection at an injection site.
Allergic and inflammatory reactions
A reaction to the agent itself is recognised, and it can present as a spreading rash, itching, or swelling that extends beyond the treated area. Severe reactions, including breathlessness or facial swelling, are emergencies. This is one of the reasons dissolving is performed in a clinical setting rather than offered as a minor appointment.
The agent does not know which hyaluronic acid is yours
The enzyme breaks down hyaluronic acid wherever it finds it. Injected filler is the intended target, and your own tissue contains the same substance. That is why too much at once can leave an area hollow or deflated, and why the amount used is a deliberate decision rather than a calculation.
Removing your own hyaluronic acid
This is the risk that patients least expect. Over-dissolving can leave the area looking hollow, deflated, or older than it did before treatment, and the change is not something that dissolving less next time can undo. It is a change in the tissue that has to be managed afterwards, sometimes by restoring volume once the area has settled. The practical defence is staging: less is used, the response is judged, and the next step is decided from how the area actually looks.
What dissolving does not do
It does not restore a previous appearance. What follows dissolving is the face as it is now without the filler, not the face as it was before the filler. It does not remove material that is not hyaluronic acid. And it does not resolve a problem that filler was being used to camouflage — if anything, it reveals it.
Weighing it
The risks are modest for most patients and are real for all of them. What makes the decision a reasonable one is that the alternative — living with a complication or a result that is causing distress — also has costs, and that the risks of dissolving are substantially lower than the risks of leaving a vascular problem or an infection untreated. The assessment is where those are weighed.
Seek care rather than waiting if
- Pain is severe out of proportion, 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.
- You have any change in vision — seek emergency care immediately.
- You develop a spreading rash, itching, facial swelling or breathlessness after dissolving.
Frequently asked questions
What are the risks of dissolving?
The risks of any injection, which include vascular occlusion — a time-critical emergency that can cause skin loss and, rarely, vision loss — together with bruising, swelling, infection, and allergic or inflammatory reactions to the agent. It also removes the patient's own hyaluronic acid along with the filler.
Can dissolving damage my skin or my face?
It can leave the area deflated or hollow where too much has been dissolved, and it can cause pigment change or skin injury in the setting of a vascular event. Those are the reasons it is staged rather than performed in a single large dose.
Does dissolving have long-term effects?
The material it removes is gone, and the tissue has changed by having had filler in it and by the dissolving. Long-term effects are mainly the change in volume and skin quality after removal rather than a continuing effect of the agent.
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.
