- Hyaluronic acid (HA) filler can be reduced with hyaluronidase injections. Calcium-based fillers, PLLA and PMMA do not dissolve in the same way, so identify the product first.
- The start of volume reduction, resolution of swelling and reinjection are different time points. Do not interpret the process as the enzyme continuing to work for one or two weeks.
- Partial adjustment is possible, but preserving exactly the desired shape is not guaranteed. Discuss which areas to reduce and which volume you want to keep.
- Worsening pain, pale or darkening skin, or visual changes need immediate medical attention rather than waiting for a cosmetic consultation.

I dislike my filler on the day it was injected. Can it be dissolved immediately?
If shape alone looks unfamiliar, first have swelling distinguished from the injected volume. Reberry Clinic explains that swelling during the one to two weeks after filler injection can be mistaken for overcorrection.
Severe pain or skin-color changes require a different response from waiting to assess appearance. Tell the clinic when treatment occurred, which area changed and how, and arrange the appropriate assessment.

Can every type of filler be dissolved?
Hyaluronidase breaks down hyaluronic acid and is used to adjust HA filler. It does not dissolve PLLA, calcium hydroxylapatite (CaHA) or PMMA.
Materials that biodegrade, such as PLLA, and permanent materials such as PMMA should not be grouped under one removal method. Non-HA filler needs assessment based on the material and symptoms; complete removal can be difficult or impossible.
The 2024 narrative review addresses HA filler complications and excludes non-HA materials. Use this distinction to identify the product, rather than interpreting material degradation time as the duration of your individual cosmetic volume.

When does volume decrease, and when should the result be reassessed?
The start of volume change and reassessment are different. Reberry Clinic describes visible reduction within hours to a day, but the response needs review according to the product, amount and condition.
CMAC guidance describes reassessment 48 hours after elective dissolution and consideration of further treatment if needed. Swelling may remain at this point; it is not a deadline by which every filler disappears in one session.
One reviewer described reduction the next day, while others reported remaining areas or less change than expected. These excerpts cannot establish product-specific success rates or appropriate reinjection intervals.
These are personal accounts from filler-dissolution users. They have not been established as reviews of Reberry Clinic or SeoulLeaguer Dermatology Clinic. Products, doses and complete outcomes were not checked against medical records.

Is swelling or a hollow appearance after dissolution a complication?
Swelling, bruising and redness can follow injection, and allergy to the enzyme must also be considered. Swelling alone does not diagnose allergy, nor does it mean every reaction can safely be left to settle.
Reducing filler may reveal pre-existing hollows or remove volume you wanted to retain. Hyaluronidase also affects HA in native tissue. Persistent hollowing or worrying changes warrant reassessment of injection sites and the extent of removal.
The reviewer below reported marked swelling that night after a dissolving injection. This short excerpt cannot establish the cause or duration of those symptoms.
Seek emergency help for breathing difficulty or swelling of the lips, tongue or throat with dizziness. Skin-color changes and visual symptoms also should not be classified as symptoms to simply wait out.

Can only the unwanted part be dissolved while the rest stays?
A staged approach can adjust selected areas. However, the spread of medication and the filler’s location mean the exact boundary you want to preserve cannot be guaranteed.
Discuss the amount and location to adjust and whether to treat in one session or review the response in stages. Ultrasound guidance can help assess filler or nodules and guide injection placement, but its use alone does not guarantee the removal result.

Does dissolving filler hurt more than having filler injected?
There is no basis to say everyone finds it more painful. Sensation varies by area, extent and injection approach, and the experiences below also differ.
One reviewer described different pain in the lips and cheeks; another found forehead dissolution less painful than expected. These are not comparative data establishing that a particular area always hurts less.
If pain worries you, discuss the area and amount to adjust and how discomfort can be reduced. Worsening symptoms around an injection should be reported separately from ordinary differences in pain perception.
These accounts illustrate individual experiences, not a comparison of clinics’ pain levels or clinicians’ skill.

Why do clinics explain allergy testing differently, and what should I ask?
Ask about the proposed medication, your allergy history and whether treatment is elective correction or an emergency. Having a skin test does not eliminate allergy risk.
CMAC guidance addresses medication and allergy history alongside limitations of skin-test results. Disclose previous hyaluronidase reactions or severe bee or wasp allergy. Testing must not delay emergency treatment when vascular compromise is suspected.

Can I consult another clinic if I do not know which filler I received?
Yes. First ask the original clinic for the product name, ingredients, treatment date, injection areas and amount, and bring whatever records are available.
An unknown product is not a reason to recommend a trial injection of enzyme. Reberry Clinic also explains that filler injected elsewhere requires more cautious assessment when product and injection-layer information is limited.
If records are difficult to obtain, explain the timing and area you know and the changes you are experiencing. Do not delay urgent assessment while trying to retrieve records.

Can filler be injected again immediately after dissolution?
For cosmetic correction, do not start by scheduling refilling on the same day. Remaining filler and swelling need assessment before deciding on retreatment.
CMAC guidance recommends waiting at least two weeks before reinjection to help make the cosmetic result more predictable, and longer when swelling is significant. This is different from saying the enzyme acts continuously for two weeks, and it does not set an identical retreatment date for everyone.
If your preferred shape has changed, discuss whether refilling is needed at all. First distinguish residual filler, swelling and your underlying facial shape as possible explanations for remaining asymmetry.

What should I ask about costs at another clinic or for repeated treatment?
At the first visit, ask what the total includes and when further treatment costs apply. Reberry Clinic lists different fees for filler originally injected there and filler injected elsewhere.
Ask whether ultrasound, medication, each area, follow-up visits and additional injections are included. A single-session fee is not necessarily the cost of complete removal. Compare the actual branch’s quote and whether tax is included.
Sources: Reberry Clinic: filler dissolution and consultation
Which symptoms need immediate care before deciding about dissolution?
Worsening pain, pale or gray-blue skin, blurred vision or reduced vision require immediate medical attention. These can signal serious complications including impaired blood flow; do not wait in a routine cosmetic consultation queue.
Report worsening symptoms after dissolving injections too. For urgent symptoms such as breathing difficulty or visual changes, seek emergency care rather than waiting for a message reply.
Sources: US FDA: dermal filler patient safety information / CMAC guidance on safe hyaluronidase use (PMID 34840662)
What should I ask during the consultation?
- Can we identify my filler product, ingredients and treatment records?
- Should the current change first be assessed as swelling, residual filler or inflammation?
- Can the areas I want reduced be distinguished from the volume I want to keep?
- Why would ultrasound be needed, and what does it cost?
- What assessment is needed given my medication and previous drug or insect-venom allergies?
- When should I be reassessed before deciding on another injection?
- What is the total including follow-up, further injections and tax?
- Whom should I contact for worsening pain or swelling, and which symptoms need emergency care?
Where should I start in my situation?
| My situation | What to discuss first |
|---|---|
| It looks excessive on the treatment day | Have swelling distinguished from injected volume. Do not wait if pain or skin-color changes accompany it. |
| Old filler feels firm or only part remains | Assess the product and location and ask about further treatment. Age alone does not determine the removal method. |
| One dissolution session made no apparent difference | Recheck the product, treated extent and progress. Do not schedule repeat injections yourself based on reviews. |
| I want to retain some volume | Discuss the target areas, staged correction and possible unintended volume loss. |
| I do not know the product and am visiting another clinic | Request product and treatment records from the original clinic and bring the available information. |
| Itching or swelling keeps returning | Seek assessment for inflammation or infection around filler rather than treating this as appearance alone. |
| I want to refill after dissolution | Assess swelling and remaining filler before deciding on reinjection timing. |
| My skin color or vision has changed | These are warning signs requiring immediate care. Do not wait for records or a routine consultation reply. |
Identify the product and symptoms, then discuss the extent to reduce
Start with the product records and the changes you are experiencing. Partial correction, further treatment and refilling are separate decisions. Without urgent symptoms, plan assessment and follow-up; changes in pain, skin color or vision need immediate medical attention.
