Filler regret: what dissolving
can — and cannot — undo

The two mistakes people make first

The first is going back for more filler “to balance it out”. One side looks heavier, or the cheek now overwhelms the jawline, and the intuitive fix is to add product somewhere else until the face evens up. This is how a single misjudged syringe becomes an overfilled face: each addition is small and locally reasonable, and the total keeps rising. Chasing symmetry with more volume treats the visible problem and feeds the underlying one.

The second mistake runs the other way: arriving at a clinic and asking for everything to be dissolved, today, in one sitting. The frustration behind that request is legitimate. The request itself is not something I will act on without an assessment, because filler placed over months or years has become part of how the face carries light and support. Removing all of it at once can trade one problem you know for several you do not.

Both mistakes share a root: decisions made in reaction to a mirror, without anyone examining what was actually injected, where it now sits, and what the surrounding tissue has done in response. That examination — not the dissolving itself — is where correction genuinely starts, which is why I begin with a structured facial assessment rather than a syringe of either kind.

What hyaluronidase actually does

Hyaluronidase is an enzyme. It cleaves the chemical bonds within hyaluronic acid, breaking the cross-linked gel into fragments the body then clears through its normal metabolic pathways. It is the reason hyaluronic acid fillers are described as reversible, and that reversibility is one of the strongest arguments for using HA in the first place.

But the word “reversible” needs handling with care. The enzyme reverses the presence of the gel. It does not reverse time, and it does not reverse what the face did while the gel was there. Skin that has been stretched over a large volume, tissue planes that have accommodated product for years, the way you have grown used to seeing your own face — none of that is dissolved with the filler.

There is also a technical dimension. Different HA fillers are cross-linked differently and resist the enzyme to different degrees, so the response to a given dose is assessed rather than assumed. And because hyaluronidase does not distinguish injected HA from the hyaluronic acid naturally present in your tissue, precision about dose and placement matters. This is precise, deliberate work, and it deserves the same planning as the original injection should have had.

The fillers that cannot be dissolved

Hyaluronidase works on hyaluronic acid and nothing else. Calcium hydroxylapatite fillers — microspheres of roughly 25 to 45 µm suspended in a carrier gel — are not affected by it. Neither are poly-L-lactic acid or polycaprolactone products, which work by provoking your own collagen response rather than by occupying space as a gel. If what was injected was one of these, there is no enzyme to send after it; the options become time, and in some situations other approaches assessed case by case.

This is why the first question in any correction consultation is the least glamorous one: what exactly was injected? Brand, product line, roughly when, and by whom. Many patients do not know, because nobody gave them records. Where the history is unclear, the examination has to work harder — how the product feels, where it sits, how it has behaved — before anyone talks about removing it.

It is also the reason I am deliberate about product choice at the outset. An injectable you cannot retreat from is a bigger commitment than one you can, and that difference should be explained before the first syringe, not discovered after the regret. The principles behind those choices are set out in my dermal fillers guide.

Why correction is staged

Filler also outstays its marketing. MRI studies have identified hyaluronic acid filler still present in the face years beyond its labelled duration — which means a face treated annually may be carrying far more accumulated product than anyone intended. Dissolving that load is not one decision; it is a sequence of them.

So I stage correction by anatomy. One region is addressed, the tissue is allowed to settle, and the face is reassessed before the next step. The mid-face may need dissolving while the chin needs none. A small area of migrated product near the lip may matter more than a larger, well-placed volume elsewhere. Each stage answers a question the previous stage asked.

The other reason for patience is the tissue envelope. Skin and soft tissue that have been stretched over chronic overfilling do not reliably snap back when the volume beneath them is removed. Empty a heavily filled face in one sitting and you can uncover laxity that was being propped up by the very product you regretted — a deflated look that reads as older, not corrected. Where that risk is real, the plan may pair staged dissolving with support for the tissue itself, which is the territory covered on the pillow face treatment page. Response varies between faces, and the sequence is judged, not templated.

Why this page has no before-and-after images

People searching for filler dissolving want to see faces that have been through it, so the absence of images deserves a direct explanation rather than silence.

Under Singapore’s Healthcare Services Act, before-and-after imagery in advertising for licensable healthcare services is prohibited. No consent form or disclaimer creates an exemption, and after-only photographs fall under the same rule. This applies identically to every licensed clinic in Singapore. A site showing you such images is not demonstrating better correction work — only weaker compliance.

What can happen instead is specific and more useful: your own face, examined in person, with an honest account of what dissolving could and could not change in your particular case.

What determines the cost

Prices for licensable healthcare services cannot be advertised in Singapore, including as ranges or “from” figures. What can be set out is what the cost of correction actually depends on.

The relevant factors are the regions involved, what the assessment finds about the type and volume of product present, whether dissolving alone is indicated or needs to be combined with support for lax tissue, and how many stages the plan is divided into. Correcting one area of migrated lip filler and unwinding years of accumulated mid-face volume are not comparable pieces of work. Fees are set out in full at consultation, once there is a specific plan to cost.

The part worth saying first

Regretting filler does not mean you were foolish to have it, and it does not commit you to either of the panicked options — more product or none. Hyaluronidase gives us a genuine tool, but only for hyaluronic acid, only with a plan, and only at the pace the tissue allows.

The honest sequence is examination first: establish what is in the face, decide what actually needs to leave, and stage its removal so that what remains still makes sense. I assess correction cases personally at Orchard Road, and where the right answer is to dissolve nothing for now, that is the answer you will get.
