For faces that look heavier, puffier or less like themselves after filler. Medical Director Dr Sin Yong locates the product with ultrasound before anything is dissolved, adjusted or added.

Correction starts by treating the existing product as the problem to be understood. Many people do not know which filler they had, how much, or when. Some products last far longer in the tissue than the face suggests, and several types can be present in the same area.
A high-frequency ultrasound scan lets Dr Sin Yong see filler deposits under the skin: their size, depth and relationship to vessels and muscle. HA filler, calcium-based products and polycaprolactone look different on the scan, which matters because each is handled differently.
The scan is paired with an examination at rest and on movement. A smile, a frown and talking all show where product drags or bunches. Photographs are taken in standard positions so later sessions can be compared fairly.
“Filler that makes a face heavier is rarely fixed by adding more. It is fixed by finding where it went.”
Dissolve. Where HA filler is the cause, hyaluronidase is placed precisely into the deposit, often under ultrasound guidance, and in small amounts so the face is not stripped of the support it still needs.
Adjust. Where some structure is genuinely missing, a small, well-placed correction may be planned after the excess has settled — never in the same session as dissolving.
Wait. Non-HA products such as calcium hydroxylapatite, polycaprolactone and poly-L-lactic acid cannot be dissolved with hyaluronidase. Here the plan may be to wait, to treat the area around them, or to refer when a surgical opinion is appropriate.
Sudden pain, blanching, a dusky or bluish patch, or vision changes after any filler need same-day medical attention. A firm, red, tender or warm lump can be an infection or inflammatory reaction rather than “extra product”. These are assessed urgently rather than booked as routine correction.
No. Hyaluronidase breaks down hyaluronic acid filler only. Calcium hydroxylapatite (for example Radiesse), polycaprolactone (for example Ellansé) and poly-L-lactic acid (for example Sculptra) are not dissolved by it, so knowing what is present comes first.
Because history is often incomplete. The scan shows which product is where and how deep, so hyaluronidase goes only where it is needed and the rest of the face keeps its support.
It can if too much is removed at once. Correction is staged in small amounts, and the face is reassessed between sessions before any further step.
Not usually. The tissue is allowed to settle after dissolving so the true baseline can be seen before deciding whether anything should be added.
It is a prescription medicine with known risks, including allergic reactions, swelling and bruising. Your history is reviewed first and the treatment is given by the doctor.
It helps, but it is not essential. Bring any records you have; the ultrasound and examination fill the gaps.
