Filler correction in Singapore is the assessment and treatment of problems after dermal filler, whether done recently or years ago. People come for it with lumps they can feel or see, filler that has moved from where it was placed, a bluish tint under thin skin, uneven sides, a result that is simply too much, or swelling that appears weeks or months later. Some come because they do not know what was injected or by whom.
Most cosmetic fillers in use are hyaluronic acid (HA), which can be dissolved with an enzyme, hyaluronidase. Other materials cannot be dissolved this way and need different approaches. Filler correction is performed by Dr Sin Yong at IN Eternity Clinic, starting with a careful history and, where useful, ultrasound to see what is there.
How it works
The mechanism,
in plain English
The plan depends on the problem. For HA lumps, migration, overcorrection, a blue tint (the Tyndall effect, where shallow filler scatters light) or asymmetry, hyaluronidase is injected into the unwanted filler so the body can clear it, typically over a day to a few days. Ultrasound helps locate the deposit, its layer and nearby vessels, so the enzyme goes where it is needed and filler you want to keep can be preserved.
Delayed inflammatory reactions, which appear as red, tender or firm swelling weeks to years after HA filler, may need a combination of approaches, which can include hyaluronidase, anti-inflammatory medicine or antibiotics depending on the cause. Vascular occlusion is different: it is an emergency where filler blocks blood flow, causing pale, blotchy or dusky skin and increasing pain, or rarely vision change. It is treated urgently with hyaluronidase at higher doses to flood the affected area, and early treatment matters.
“Before anything is dissolved or added, the first question is what filler is there, where it sits, and whether it is HA at all.”

Is it right for you
Who it suits,
and who it does not
Filler correction usually suits anyone unhappy with how HA filler has settled: visible or palpable lumps, filler that has spread above the lip or into the under-eye, a bluish tint, uneven results, or a face that looks heavier than intended. It also suits people with swelling or firmness appearing long after filler, and people who are not sure what was injected and want it assessed before having anything more.
Hyaluronidase does not dissolve non-HA fillers such as poly-L-lactic acid, calcium hydroxylapatite, polycaprolactone, silicone or polyacrylamide, so these need a different plan, sometimes including surgical opinion. People allergic to hyaluronidase, or with significant bee or wasp sting allergy, need careful assessment and testing. Active infection needs treating first. Suspected vascular occlusion is an emergency and should not wait for a routine appointment.
What to expect
Consultation, session
and aftercare
At consultation, Dr Sin Yong takes a full history of previous treatments, examines the area and, where useful, scans it with ultrasound to see where the filler sits and what it looks like. He explains the options, including whether dissolving all, part or none of the filler makes sense. Allergy history is checked and a small test may be done. If treatment goes ahead, hyaluronidase is placed precisely into the unwanted filler.
Mild swelling, redness or itch for a day or two is common. Avoid massaging the area, strenuous exercise and saunas for about a day. The area is reviewed a few weeks later once it has settled, and some problems need more than one round. If you develop pale, blotchy or dusky skin, increasing pain or any vision change after filler anywhere, seek help immediately.

What the research says
The evidence,
with sources
A guideline on the safe use of hyaluronidase in aesthetic medicine sets out when to use the enzyme to dissolve HA filler, how formulations differ, its side effects, and why a history of bee or wasp sting allergy increases the risk of allergic reaction, along with guidance on skin testing. A 2026 systematic review and meta-analysis of 231 patients with HA-related vascular complications found that early hyaluronidase, within six hours, significantly improved outcomes, and that higher doses were linked with better resolution of skin necrosis.
Delayed inflammatory reactions are rare. A 2026 meta-analysis pooling 242 studies found an incidence of about one event per 2,000 patients followed for one year, with a median onset of about three months but a range from two weeks to 12 years; nodules, redness, swelling and firmness were common, and management often involved a dissolving enzyme and other prescription medicines. Ultrasound literature supports imaging to see displaced filler and guide hyaluronidase directly into a deposit.

Common questions
Your questions,
answered
How much does filler correction in Singapore cost?
The cost depends on the problem, the area, how much filler needs dissolving and whether ultrasound and more than one session are needed. Pricing is given at your consultation with Dr Sin Yong at IN Eternity Clinic. SkinRev Lab does not perform injections, but our team can pass on your enquiry and help you book an assessment.
Can filler correction in Singapore fix filler done elsewhere?
Yes, many people seek correction for filler done elsewhere, sometimes overseas. It helps to bring any records of the product used. If you do not know, ultrasound can show where the filler sits and sometimes suggest what type it is. Dr Sin Yong will explain whether dissolving is likely to help or whether a different approach is needed.
How quickly does hyaluronidase work?
Hyaluronidase starts breaking down HA filler within minutes to hours, and most of the change is seen over a day to a few days as swelling settles. Some dense or older filler deposits respond more slowly and may need another round. Your face is reviewed a few weeks later before anything further is decided.
What is the Tyndall effect?
The Tyndall effect is a bluish tint seen when HA filler sits too close to the surface under thin skin, most often under the eyes. Light scatters through the gel, producing the colour. It does not usually settle by itself, but it generally responds well to small, targeted amounts of hyaluronidase.
Why has my filler swollen months later?
Delayed swelling can be caused by a delayed inflammatory reaction, sometimes triggered by an infection, a vaccine, dental work or illness, or by water-binding of filler in areas that drain slowly, such as under the eyes. It should be assessed rather than left. Treatment depends on the cause and may include hyaluronidase or medication.
What should I do in a filler emergency?
If after filler you notice skin turning pale, white, blotchy, purple or dusky, pain that is increasing, or any change in vision, treat it as an emergency. Contact the clinic that treated you immediately, or go to the nearest emergency department if you cannot reach them. Early hyaluronidase makes a real difference to outcomes.
