Filler Ultrasound Scan in Singapore
High-frequency skin ultrasound shows where earlier filler sits, how deep it is and what kind of material it is likely to be. At IN Eternity Clinic, Medical Director Dr Sin Yong scans before filler correction so that treatment is aimed at the filler and not at the tissue around it.

WhatsApp to Enquire →Key facts ↓A filler ultrasound scan uses a small high-frequency probe on the skin to show earlier filler as it sits in the face. It shows where the product is, how deep it lies and how much is there, and it helps tell hyaluronic acid from products that cannot be dissolved. At IN Eternity Clinic in Singapore, Dr Sin Yong scans before dissolving or correcting filler, including filler done elsewhere. It is painless and uses no radiation.
- Different fillers look different on ultrasound: hyaluronic acid usually appears as dark, fluid-like pockets, calcium hydroxylapatite appears bright and casts a shadow, and silicone gives a "snowstorm" pattern [1].
- It answers the first question in any correction: is this lump filler, swelling, a cyst or your own tissue? Treatment differs for each [1].
- It makes dissolving more precise: the enzyme can be placed into the deposit under guidance instead of across the whole area [2].
- It shows vessels as well as filler: Doppler mode displays blood flow, which helps in planning and in assessing a suspected blockage [2].
- Filler can outlast its label: imaging has found hyaluronic acid filler still present years after injection, so "it must be gone by now" is not a safe assumption [3].
What a filler ultrasound scan shows
Skin ultrasound uses sound waves at a much higher frequency than a pregnancy or abdominal scan, which gives fine detail in the first one to two centimetres under the skin. That is where filler sits. The probe is moved over the area with a little gel, and the image appears on screen in real time [1].
- Where the filler is. Under the eye, in the cheek, beside the nose, in the lip or along the jaw, and whether it has moved from where it was placed.
- How deep it is. In the skin, in the fat under it, or on the bone. Filler that is too shallow is a common cause of lumps and a bluish tint.
- How much is there. A thin layer, a single deposit, or several layers from different years.
- What it is likely to be. Hyaluronic acid, a collagen stimulator or a permanent material, each of which looks different [1].
- What is not filler. Swelling, a cyst, scar tissue, fat or a salivary gland can all feel like a filler lump.
When a scan is worth doing
- Before dissolving filler, especially when you are not sure what was injected or where.
- A lump, nodule or firm area that has not settled after two to four weeks.
- Puffiness or a bluish tint under the eyes after filler.
- A face that looks heavier or wider after repeated filler over the years.
- Filler that appears to have moved, for example above the lip border or below the tear trough.
- Before adding new filler to an area that has been treated several times.
- Urgently, where blocked blood flow is suspected after an injection [2].
How the scan is done
You sit or lie back, gel is applied, and Dr Sin Yong moves the probe over each area in turn while you watch the screen. There is no needle, no radiation and no downtime. Each area takes a few minutes. The findings are explained on the spot: what is there, at what depth, and what that means for treatment.
If dissolving is planned, the scan can guide the injection so that the enzyme goes into the filler deposit. A repeat scan at review, usually about two weeks later, shows what has gone and what remains [2].
What ultrasound cannot do
- It cannot name the brand of a filler. It shows the type of material, not the label.
- Very small amounts, or filler spread thinly through tissue, can be hard to see.
- It does not replace a medical history. Records of what was injected, and when, still help.
- Reading the image takes training. The scan is only as useful as the person interpreting it.
- A scan does not treat anything by itself. It makes the treatment that follows more accurate.
What happens next
What follows depends on what the scan shows. Hyaluronic acid can be dissolved in small, staged doses. Products that do not dissolve are managed differently, and some are left alone. Where the lump is not filler at all, you are told so and referred if needed. See dissolving filler and filler correction in Singapore, which fillers cannot be dissolved and lumps after filler. Results vary between people, and suitability is decided at consultation.
Frequently asked questions
Does a filler ultrasound scan hurt?
No. The probe rests on the skin with gel. There are no needles and no radiation, and you can return to normal activity straight away.
Can ultrasound tell which filler I had?
It can usually tell the type of material, for example hyaluronic acid as against a collagen stimulator or a permanent filler, because they look different on screen. It cannot identify the brand.
Do I need a scan before dissolving filler?
It is not compulsory, but it makes dissolving more precise. The scan shows where the product sits and whether it is a type that dissolves, so less enzyme is placed in the wrong areas.
Can a scan find filler from years ago?
Often, yes. Filler can remain far longer than its label suggests, and imaging has shown hyaluronic acid still present years after injection. Very small or widely spread amounts can be harder to see.
Can I have a scan if my filler was done at another clinic?
Yes. Dr Sin Yong scans and assesses filler regardless of where it was injected. Bring any records you have of the product and the date.
How much does a filler ultrasound scan cost in Singapore?
It depends on the number of areas scanned and whether treatment follows in the same visit. The scan and any treatment are set out at consultation. The consultation fee is S
Is a filler scan the same as HIFU or an ultrasound facial?
No. A diagnostic ultrasound scan only produces an image. HIFU uses focused ultrasound energy to heat tissue for lifting, and an ultrasound facial is a skin treatment. They are different devices with different purposes.
