In Brief

Pillow face treatment in Singapore usually means mapping excess hyaluronic acid filler by ultrasound, then dissolving it with hyaluronidase in stages. It suits filler that looks overdone or has moved. It cannot dissolve non-HA fillers or grafted fat, or tighten lax skin. Results vary between people.

What the Research Shows: Pillow Face Treatment Singapore

  • 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). [1]
  • A 2015 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. [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. [3]
  • 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. [5]

About This Treatment

What pillow face is

Pillow face describes a puffy, rounded look from too much filler, or filler in the wrong layer, which blurs the natural contours. The medical term is facial overfilled syndrome. It usually affects the cheeks, under-eyes, lips and jaw. It tends to build over repeated treatments, as new filler goes over filler that has not gone. Hyaluronic acid can stay in tissue for a long time, and it draws in water.

Pillow face rarely resolves on its own, and more filler cannot correct a face that already holds too much. The aim of correction is to move the face back towards natural proportions.

The first question is what is actually in the tissue. Some puffiness is hyaluronic acid. Some is a collagen stimulator or grafted fat, and these do not respond to hyaluronidase. Dr Sin Yong therefore images before treating, and he asks you to pause before adding any new product.

Pillow face treatment in Singapore: who it may suit

Excess or misplaced filler

Known or suspected hyaluronic acid looks too much, or sits in the wrong place.

Migrated filler

Product has moved from where it was placed.

Build-up from repeat treatments

Several rounds have added up over time.

A wish to reassess

You want natural proportions, and will review before adding anything.

Signs that may point to overfilling

Wider in photos

The face looks fuller than a few years ago, without weight gain.

Changes on smiling

Cheeks stay prominent, and the eyes narrow.

Under the eyes

A soft ridge or bluish tint does not change with sleep.

Around the lips

A shelf or shadow sits above the lip border.

A growing need

Each treatment feels needed sooner, and the amounts keep rising.

Not proof alone

Several of these have other causes, such as normal swelling, migrated filler, poorly drained fluid, a delayed reaction or grafted fat.

Matching the material to the method

What is causing the excessWhat may be usedNote

Why the material decides the method

A review attributes facial overfilled syndrome to excessive filler and injection technique, and says anatomy plays a significant role. [7] An overfilled face often holds more than one product. Hyaluronic acid may sit over an earlier collagen stimulator, or grafted fat may sit beside filler. Dr Sin Yong scans each area himself, so each layer gets the step that suits it. Hyaluronic acid comes first, the area is reassessed, and the Sculpting mode is then used on what remains. See filler correction.

How ultrasound-guided dissolving works

01
Assessment and imaging
History, palpation and assessment at rest and in movement come first. Concern areas are marked. Ultrasound then shows where filler sits, how deep it is, how far it has spread and whether it is likely hyaluronic acid. It also shows any fluid or inflammation.
02
Written plan and quote
Your plan marks areas to dissolve and areas to keep. A skin test may come before staged dissolving.
03
Dissolving
Diluted hyaluronidase is placed into the mapped deposit itself.
04
Observation
You stay for a period afterwards, with emergency treatment on hand for a rare wider allergic reaction.
05
Review
Dissolving develops over the following days. Results are checked between rounds, and heavy or layered filler may need several, at an interval set at review.

After correction

Staging matters. Emptying the face in one visit can look older and flatter, and some filler may be giving useful support. The face may look hollower than expected for a time, and ageing once masked by filler may show. The true result is judged once swelling has settled. New filler is considered only after the face has settled and been reassessed. Often, support comes from energy treatment that adds no product. The VF Lift uses monopolar radiofrequency along vertical vectors. To lower the chance of this happening again, check what filler is still present before any further treatment, judge results in smiles and photos, and keep records.

Who should wait or discuss it first

Infection or inflammation

Active problems in the area come first.

Pregnancy or breastfeeding

Treatment waits, pending review.

Hyaluronidase allergy

A known allergy rules it out.

Bee or wasp venom allergy

This must be raised for discussion.

Bleeding risk

Tell us about blood thinners or a bleeding tendency.

Expecting one-round removal

Full removal in one session is not realistic.

Non-HA puffiness

If the cause is grafted fat or a non-HA product, hyaluronidase will not help. If ultrasound finds no filler where the puffiness is, dissolving will not help either, and the plan changes.

What it cannot do

Dissolve other materials

CaHA, PCL, PLLA, PDLLA, grafted fat, and brands such as Radiesse, Ellansé, Sculptra and Juvelook do not respond.

Remove everything at once

Treatment is staged, and dissolving may be incomplete.

Act as an undo button

The face does not simply reset.

Promise an outcome

No result or duration can be assured.

Tighten lax skin

Skin may not fully tighten after volume is removed.

Risks to understand

Swelling, tenderness and bruising at injection sites are common, and the face can look puffier for a short time. Allergic reactions can happen. These may be local itching or swelling. Rarely, the reaction is more widespread. You may also find the correction goes too far or not far enough. Hyaluronidase acts on your body's own hyaluronic acid too, so a flatter or hollow look can appear for a time. Staged dissolving, incomplete dissolving and skin that does not fully tighten are all possible.

Aftercare and urgent signs

In the first 24 hours, do not press or massage treated areas unless advised, and use a cool compress if advised. In the first week, expect swelling and bruising. Avoid heavy exercise or heat if tender, and have no new filler or facial treatment until reviewed. Keep out of direct sun while bruised or swollen, and use gentle skincare. Seek urgent care for worsening pain, pale or dusky skin, breathing difficulty or changes in vision.

What affects the fee

No prices are published. The fee depends on the areas treated, the amount and spread of filler, ultrasound use, the amount of hyaluronidase and any planned refinement. You receive a written quote after consultation. See how we quote.

Frequently Asked Questions

Ultrasound maps the filler, then hyaluronidase is placed into the deposit in stages, with review between rounds.
No. Hyaluronidase works on hyaluronic acid only. CaHA, PCL, PLLA, PDLLA and grafted fat do not respond.
Not always. Treatment is staged, and heavy or layered filler may need several rounds.
Hyaluronidase also acts on your own hyaluronic acid, so a flatter or hollow look can occur for a time.
It shows where filler sits and how deep, so product can go into the deposit itself.
It may not fully tighten. Lax skin is referred to a plastic surgery specialist.
Avoid new filler until you have been reviewed. You may not need more.
Raise this first. Bee or wasp venom allergy is flagged for discussion before treatment.
It may be used where the excess is a collagen stimulator, layered filler or grafted fat. Each deposit is mapped with ultrasound, and the Sculpting mode is directed at it without an incision. Hyaluronic acid is usually dissolved instead. Inflamed lumps are treated medically first. We found no published study of this use, laser heat has its own risks, and response varies.
