Patients sometimes come to Silk because they are unhappy with filler they have had somewhere else. The reasons range from the cosmetic, where the result simply does not look how the patient hoped, to the clinical, where late swelling, migration, or hardness has developed months or years after treatment. The conversation in each case is honest, calm, and focused on what can be done.
I am Shontelle, the registered nurse at Silk Clinical Aesthetics. This article walks through the most common reasons patients seek correction of previous filler work, what the realistic options are, and what we offer at Silk.
What Counts as a Filler Complication
Not every unhappy filler result is a complication in the strict sense. The category covers a spectrum.
Cosmetic disappointment: the technique was sound, the placement was reasonable, but the result is not what the patient wanted. Common in over-treatment, in cases where the wrong product was used, or where expectations were not aligned with what the treatment can do.
Late-onset swelling or inflammation: an area of filler that looked fine for months or years suddenly becomes puffy, tender, or visible. Triggered sometimes by illness, vaccination, dental work, or no obvious cause.
Filler migration: filler has moved from where it was placed. Common in the lips and tear trough, often producing a duck-like lip projection or persistent under-eye fullness.
Visible Tyndall effect: a bluish or grey discolouration where filler has been placed too close to the surface, particularly visible under the eyes. Light scatters through the gel, producing the colour.
Lumps and palpable nodules: small areas of filler that have not integrated, or that have been placed in a way that left a discrete lump.
Granulomas and biofilms: rarer, more inflammatory complications that can present as firm, tender nodules, sometimes appearing months after the original treatment.
Vascular complications: rare but serious, including vascular occlusion (filler interrupting blood supply) and skin necrosis. These are emergencies that should be addressed at the time of original treatment, not later.
The early ones in this list are the most common reasons patients seek correction. The later ones are rarer and require careful clinical management.
The Most Common Tool: Hyaluronidase
Hyaluronic acid filler is the dominant product class in considered aesthetic practice partly because it is reversible. Hyaluronidase is an enzyme that breaks down hyaluronic acid, including the cross-linked hyaluronic acid that makes up most modern fillers. It is delivered by injection into the area where dissolution is needed.
Hyaluronidase is the right answer for most filler problems involving hyaluronic acid filler. It can:
- Dissolve filler that has migrated outside its intended area.
- Reduce the volume of an over-corrected area.
- Resolve persistent swelling that is filler-related.
- Treat early-stage vascular occlusion as part of an emergency protocol.
- Reset an area that has accumulated multiple layers of filler from previous treatments.
The treatment is straightforward in skilled hands. A small amount of hyaluronidase is injected into the affected area, the filler softens within minutes, and the visible improvement appears over the following hours and days.
What hyaluronidase cannot do:
- Dissolve permanent or semi-permanent fillers (such as silicone or polyalkylimide). These products are not reversible; correction requires different and sometimes surgical approaches.
- Reverse changes in the surrounding tissue caused by long-standing filler. Skin that has been stretched by years of overfilling does not always return to its previous state.
- Fix complications that are not actually filler-related (such as fat herniation that has been mistaken for filler issues).
There are some specific risks with hyaluronidase, including allergic reactions (rare but possible) and the potential to dissolve native tissue hyaluronic acid alongside the filler. A skilled practitioner uses targeted injections and accepts a small period of altered tissue quality that resolves over weeks.
Specific Scenarios and What we Do
Migrated Lip Filler
Migrated lip filler is one of the more common reasons patients come to us for correction. The presentation is typically a fuller, projected upper lip that has moved beyond the natural lip border, creating what some patients describe as a "duck pout".
The treatment is targeted hyaluronidase to dissolve the migrated filler, followed by a settling period of two to four weeks. We then reassess. In some cases, no further treatment is needed because the patient discovers their natural lip looks better than the filled version. In others, conservative re-treatment within the natural lip border is appropriate.
We do not retreat lips at the same appointment as the dissolving session. Settling time is part of the protocol.
Migrated or Accumulated Tear Trough Filler
Persistent under-eye puffiness or a bluish tinge that has developed over time after filler is often a sign of filler that has migrated, accumulated water, or been placed too superficially. The standard approach is targeted hyaluronidase to dissolve the affected filler, followed by a settling period.
We are conservative about retreating the tear trough after dissolution. In many cases, the area looks better without further filler. If treatment is appropriate, it is approached carefully with a different product or technique. For more on the clinical considerations, see Tear Trough Filler: When It Works and When It Makes Things Worse.
Over-Filled Cheeks or Midface
A common presentation in patients who have had multiple filler appointments over years. The face looks fuller and more obviously treated than the patient wants, and the natural facial contours are softened. The treatment is targeted hyaluronidase in the affected areas, often performed in stages over a few sessions to allow the tissue to adjust gradually.
In some patients, particularly those with significant volume of older filler, full reversal can produce an initial appearance of deflation as the tissue adjusts. We discuss this clearly before treatment so the trajectory is expected rather than surprising.
Late-Onset Swelling
A previously settled filler area that becomes puffy or tender months or years after treatment can be alarming. The most common trigger is an immune response to the filler, sometimes precipitated by illness, vaccination, dental work, or no obvious cause.
The clinical approach depends on severity. Mild cases sometimes resolve with anti-inflammatory medication and time. More persistent or severe cases are typically treated with targeted hyaluronidase to remove the filler, sometimes alongside a short course of oral steroids. The area is then reassessed once the inflammation has settled.
Granulomas and Persistent Nodules
Rare, but they happen. Firm, often tender lumps that develop weeks to months after filler. The mechanism varies, including foreign body reactions and biofilm-related inflammation.
Treatment in these cases is more involved than simple dissolution. The protocol can include hyaluronidase, oral antibiotics if biofilm is suspected, intralesional steroid injections, and in some cases referral to a plastic surgeon or dermatologist. We assess each case individually and refer when the right answer is outside our scope.
Vascular Complications
Vascular occlusion, where filler interrupts blood supply to an area of skin, is the most serious filler complication. It is rare in skilled hands but always possible. The presentation is typically immediate or within hours of treatment: blanching, severe pain disproportionate to the procedure, dusky or mottled skin, and progressive change.
This is an emergency. The treating clinic is responsible for the immediate response, which involves hyaluronidase, warm compresses, vasodilators, and close monitoring. If a vascular occlusion is suspected at any point during or after treatment, the patient should call the treating clinic immediately. If the treating clinic is unavailable, the patient should go to a hospital emergency department.
We keep hyaluronidase on site at all times and follow established vascular occlusion protocols. We will also assist patients who present to us with concerns about a vascular event from a recent treatment elsewhere, with the understanding that time-sensitive cases should ideally return to the treating clinic first.
What Silk Offers
We accept patients seeking correction of previous filler work, including patients who have been treated by other clinics. The conversation is non-judgemental: we are not interested in critiquing another practitioner, only in working out what is best for the patient now.
Our standard approach for non-emergency correction:
- A consultation and assessment, often including photographs to establish the baseline.
- A discussion of what is appropriate to dissolve, what to leave, and the realistic outcome of dissolution.
- Hyaluronidase treatment, with clear consent and discussion of risks (including the small risk of allergic reaction).
- A settling period of typically two to four weeks before any retreatment.
- Reassessment, with retreatment only if appropriate. Sometimes the right answer after dissolution is no further filler.
For older work in patients who have had multiple sessions of filler over years, we often stage the dissolution across several appointments rather than attempting full reversal in one session. This produces a more controlled tissue adjustment and a better final result.

What We Cannot Do
We are not the right clinic for every complication.
Permanent filler complications often require specialist input from a plastic surgeon. We can assess and refer.
Long-standing tissue changes from years of overfilling sometimes do not fully resolve with dissolution. We will be clear about this in consultation.
Some inflammatory complications benefit from a longer-term plan that includes specialty referral. We are happy to be the clinic that coordinates that, but we will not pretend to manage what is outside our scope.
Vascular emergencies should ideally return to the treating clinic immediately. We will help, but the time-sensitive component of these cases is best handled by the practitioner who performed the treatment.
Frequently Asked Questions
How quickly does hyaluronidase work?
The filler typically begins to soften within 30 to 60 minutes of the injection. Visible improvement is often noticeable the same day, with the full result developing over 24 to 72 hours. In some cases, particularly with older or more cross-linked filler, a second hyaluronidase treatment is needed to complete the dissolution.
Will dissolving my filler return my lips or face to how they were before treatment?
Mostly, yes. Hyaluronidase removes the filler. The surrounding tissue usually returns close to its pre-treatment state, although tissue that has been stretched for years by significant volumes of filler can take longer to fully retract, and in some cases does not fully return to its previous appearance.
Is hyaluronidase safe?
Hyaluronidase has a long clinical track record and is generally well tolerated. Allergic reactions are possible but rare. We perform a sensitivity test before first-time use in some patients, and we are equipped to manage any reaction that occurs.
Can I have new filler at the same appointment as dissolving old filler?
We do not recommend this. The dissolved area needs time to settle, often two to four weeks, before any new treatment is considered. Layering new filler immediately on top of dissolved tissue produces a less predictable result.
What does dissolving filler cost?
Hyaluronidase treatment at Silk starts from $250 per session depending on the area and the volume of filler being dissolved. Multi-session protocols for complex cases are quoted after consultation. For our full pricing, see the pricing page.
What if I do not know what was injected previously?
Bring whatever records you have, but do not worry if you have none. The clinical assessment can usually identify whether the area has hyaluronic acid filler in it, and the response to test injections gives further information. The first session is sometimes diagnostic as much as treatment.
