Pillow Face Correction Singapore: A Patient Guide

How overfilling happens, and how it is carefully addressed

A puffy, rounded look after filler usually builds up slowly. Correction means finding where the product sits, then removing only what should go. Results vary.

In Brief

Pillow face correction in Singapore finds excess hyaluronic acid filler with ultrasound, then dissolves it selectively with hyaluronidase. It suits known or suspected overfilling or migration. It cannot dissolve fat or non-HA fillers, and it is not an undo button. Results vary and rounds may be staged.

What the Research Shows: Pillow Face Correction Singapore

  • A 2015 expert consensus on filler-related impending necrosis, not a trial, recommended at least 200 U of hyaluronidase, more if no improvement within 60 minutes, and said early treatment within 24 hours usually gave better outcomes. [1]
  • A 2023 retrospective case series of 39 patients with vascular filler events, all flooded first, reported a mean 122.5 IU hyaluronidase with ultrasound-guided targeting versus 1519.4 IU with flooding (level of evidence 4). [2]
  • A 2024 preliminary case series of 5 women with acute vascular occlusion from filler found the 4 treated promptly fully recovered and the fifth, treated later, markedly improved, with a mean of 87 IU hyaluronidase across all five under ultrasound. [4]
  • A 2023 narrative overview from 2 clinical centres in 2 countries described equipment choice and 2 techniques for ultrasound-guided filler injection, scanning before or while injecting, with no numerical outcomes. [6]

About This Topic

What pillow face is

Pillow face is the everyday name for facial overfilled syndrome. The face looks puffy and rounded, and natural contours blur. It usually shows in the cheeks, under the eyes, around the lips and along the jaw. It often looks heaviest in a smile, when the eyes narrow.

It rarely comes from one treatment. It tends to build across repeat sessions, sometimes with filler sitting in the wrong layer. Because it builds gradually, each step may have seemed small at the time.

Pillow face correction in Singapore: the short answer

The usual route is mapping followed by selective dissolving. Areas with appropriate volume are left alone. This is a staged, careful process and not a single reset. The treatment is described on the pillow face treatment page, which explains each stage. Worries about filler complications more widely are covered under complication care.

Why overfilling happens

Filler stays longer than expected

Hyaluronic acid filler can stay in the tissue for longer than people expect.

Water uptake

Hyaluronic acid draws in water.

Wrong placement

Filler placed to chase a line or shadow can sit in the wrong plane.

Look-alikes

Migration, fat-graft overgrowth and fluid or swelling can mimic overfilling, and each needs a different plan.

How correction is carried out

01
History and examination
Past treatments are reviewed, the face is felt, and it is assessed at rest and in movement.
02
Ultrasound mapping
Concern areas are marked. Ultrasound shows where filler sits, how deep it is and what is nearby, before any enzyme is placed.
03
Selective dissolving
Diluted hyaluronidase is directed into the mapped deposits. Dissolving develops over several days.
04
Staged rounds
Heavy or layered filler may need more than one round. The interval is set at review.
05
Reassessment
Once the face settles, any refinement is planned. This is often energy-based treatment and not more filler.

Why dissolving is staged

Taking everything out at once can leave the face looking older or flatter. Filler may also be masking changes that came with age. So the aim is to remove what is excess and leave what is doing a useful job. Each round is judged after the face has settled, and the next step is decided then. People expecting all filler to disappear in one round are asked to wait and reconsider, because that is not what this treatment does.

Who it suits, and who should wait

May suit

Known or suspected excess or misplaced hyaluronic acid filler, including build-up from several sessions, if you are willing to be reassessed before adding anything new.

Should wait

Active infection or inflamed skin, and pregnancy or breastfeeding, where the plan is reviewed first.

Caution

Known hyaluronidase allergy, blood thinners or a bleeding tendency, and bee or wasp venom allergy, which is flagged and discussed.

Referred on

Heavy lax skin or structural change after dissolving goes to a plastic surgery specialist.

What correction cannot do

It is not an undo button. Stretched tissue may not fully tighten. Filler broken into small pockets may need several rounds, so complete removal in one visit cannot be promised. Dissolving everything at once can leave the face looking older or flatter. Hyaluronidase does not act on fat or non-HA fillers. Any ageing that the filler was masking may also become visible.

After dissolving: what comes next

Reassessment comes before anything new. If skin looks loose or the face looks flat once it has settled, refinement is often energy-based and not more filler. Options are chosen after review. Heavy lax skin goes to a plastic surgery specialist. If filler is considered again later, the amount, plane and reason should be clear. For how filler should be chosen in future, read the dermal fillers guide.

Risks to discuss first

01
Expected
Swelling, tenderness and bruising at injection sites. The face may look puffier for a short time.
02
Allergy
Local itching or swelling can signal allergy. A wider allergic reaction is rare. Patients are observed afterwards and emergency treatment is kept on hand.
03
Over or under-correction
The enzyme also acts on your own hyaluronic acid, so the face can look flatter or more hollow for a while.
04
Emergencies
Difficulty breathing, throat tightness or rapidly spreading swelling, or any vision change or eye pain, needs a 995 call. Worsening pain, or pale, dusky or mottled skin, needs urgent review by the injecting doctor or A&E.

Aftercare and fees

In the first 24 hours, avoid pressing or massaging the area unless advised. In the first week, expect swelling and bruising, and avoid new filler or facial treatments until reviewed. Keep out of direct sun while bruised or swollen. The fee depends on the areas treated, the amount and spread of filler, whether ultrasound mapping is needed, the amount of hyaluronidase, and whether refinement is considered later. A written quote follows history, examination and, where useful, ultrasound.

Frequently Asked Questions

Mapping excess filler with ultrasound, then dissolving hyaluronic acid selectively with hyaluronidase. Heavier cases may be staged, and the face is reassessed before anything else is considered.
No. Hyaluronidase only acts on hyaluronic acid. Radiesse, Ellansé, Sculptra and PDLLA need a different approach, and so does fat.
Sometimes not. Filler in small pockets or layers may need several rounds. The number depends on filler load and is set at review.
It might for a while. Any ageing the filler was masking may show, and the enzyme can make the face look flatter or more hollow for a time.
It shows where filler sits, how deep it is and what is nearby. Enzyme can then be directed into the mapped deposits.
Allergy is possible, so tell the doctor about any known hyaluronidase allergy or bee or wasp venom allergy. Patients are observed afterwards.
Not straight away. Reassessment comes first, and refinement is often energy-based and not more filler.
Then hyaluronidase will not dissolve it. Ellansé, Sculptra, Radiesse and PDLLA are mapped with ultrasound, and Dr Sin Yong uses the Sculpting mode of Time Freeze Laser LCLR® on the excess, without an incision. Inflamed lumps are treated medically first, and response varies.
