For the cheek on its own, see overfilled cheeks and how they are dissolved.

An overfilled face rarely happens in one visit. It builds up quietly, one top-up at a time, until the cheeks look heavy, the smile looks wide and friends start to say you look tired or puffy. The good news is that most of it can be corrected without surgery, once you know exactly what is under the skin.
An overfilled face is one that holds more injected volume than its bones, fat pads and skin can carry. Instead of restoring a contour, the filler starts to change the shape of the face. In medical writing it is called facial overfilled syndrome; on social media it is called pillow face. Both describe the same thing: a soft, rounded, slightly swollen look that no longer moves like a natural face.
It is not a problem of one bad injection. Most overfilled faces Dr Sin Yong sees in Singapore have had filler from several clinics over several years, often with a mix of products, and nobody has looked at what is still there.

Filler lasts longer than most people think. Hyaluronic acid filler is often described as lasting months, but ultrasound regularly shows it in the tissue years later. When a top-up is planned on the assumption that the last one has gone, the new filler sits on top of the old.
It holds water. Hyaluronic acid draws in water, so a face with several layers can swell more on some days than others.
It moves. Filler can drift from where it was placed, for example from the cheek into the under-eye or from the lip border into the skin above it.
Volume is used to treat sagging. When the real problem is loose skin or a descending jawline, adding volume to lift it eventually makes the face bigger rather than higher.
Different materials are layered. Hyaluronic acid, Sculptra, Radiesse, Ellansé and fat grafts are often found in the same face. They behave differently and are removed differently, which is why guessing does not work. The fat graft or filler comparison explains how the two most common causes are told apart.
Usually not quickly on its own. Hyaluronic acid filler breaks down slowly and keeps holding water while it does, so many people wait months for a change that does not come, and some are offered more filler in the meantime.
The face can return close to its own shape once the excess is removed. How close depends on how long the filler has been there, whether the skin over it has stretched, and what material it is. That is decided at the assessment, not promised in advance.
Dr Sin Yong’s approach is to see first and treat second, and to take away rather than add.

“An overfilled face is not fixed by adding more. I map what is there first, then take away only the excess.”

Fresh filler. Swelling in the first two weeks after filler is expected and is not the same as overfilling. Unless there is a warning sign, it is usually judged after it settles.
Pregnancy and breastfeeding, active skin infection, or a known allergy to hyaluronidase mean dissolving is postponed or a different plan is used.
Seek urgent care if, during or soon after any filler injection, the skin turns white, grey or dusky, pain is severe and increasing, or vision changes. These can be signs of a blocked blood vessel and need same-day treatment.

An overfilled face is a face that has had more filler than its structure can carry, usually built up over several top-ups. It looks puffy, wide or heavy, most of all when smiling. The same picture is called pillow face or facial overfilled syndrome.
Not quickly on its own. Hyaluronic acid filler can stay for years and holds water, so the fullness often persists. Where hyaluronic acid is the cause, it can be dissolved selectively after ultrasound mapping, and the face is reviewed as it settles.
Too much filler can make the face look puffy or unnatural, can drift into nearby areas, and over time can stretch the skin it sits under. The longer layers build up, the more important it is to map what is there before anything else is done.
In most cases, yes. Excess hyaluronic acid is dissolved with hyaluronidase after ultrasound mapping, and filler that cannot be dissolved, such as Sculptra, Radiesse or Ellansé, or grafted fat, is reduced with the Time Freeze Laser LCLR®, without an incision.
Correction is usually staged. Hyaluronidase starts working within hours, swelling settles over a few days, and the face is reviewed after about two weeks before deciding whether more is needed. Several layers of filler may need more than one visit.
Dissolving only the excess is meant to bring back the face’s own contours, not to empty it. Mapping with ultrasound first means filler that is helping can be left in place, and loss of support is treated with tools other than volume.
They describe the same problem. “Pillow face” is the popular term for a soft, puffy, overfilled look; “facial overfilled syndrome” is the term used in the medical literature. The pillow face guide covers it in more detail.
Yes, though not with hyaluronidase, which only breaks down hyaluronic acid. Dr Sin Yong has treated hard Ellansé nodules, Juvelook lumps and mixed, encapsulated filler; excess biostimulator and fat are treated with the Sculpting mode of the Time Freeze Laser LCLR®, always after confirming on ultrasound what is there.
