Grafted fat cannot be dissolved like filler. When a fat transfer has left the cheeks, under-eyes or temples heavier than planned, Dr Sin Yong first maps what is fat, what is filler and what is ageing, then reduces the excess from the surface with his Time Freeze Laser LCLR® protocol, adding VF Lift – Vertical Facelift where the face also needs lifting or contouring.
Fat grafting correction is the assessment and reduction of excess grafted fat when a fat transfer has left the face fuller, heavier or lumpier than planned. Because grafted fat is living tissue, hyaluronidase does not dissolve it. Dr Sin Yong maps the face with ultrasound, then uses the lipo-remodelling arm of Time Freeze Laser LCLR® to reduce and reshape the excess graft from the surface over a planned series, adding VF Lift – Vertical Facelift for patients who want more lift or contour. Surgical removal, such as microliposuction, is discussed when the excess is large and stable. He assesses and treats this personally at his clinic on Orchard Road, Singapore.
“Grafted fat is not a product to be dissolved. It is tissue, so it is reduced the way tissue is reduced: carefully, in stages, and only once it is clear what is fat and what is not.”
— Dr Sin Yong
With filler, the volume in the syringe is roughly the volume in the face. Fat behaves differently. Only part of what is injected survives, and how much survives varies between people, between areas of the face and between techniques. To allow for that loss, fat is often placed generously, and when more of it takes than expected the result is fuller than planned.
Repeated sessions add a second layer. A review of facial fat grafting complications notes that overcorrection is seen more often after repeated grafting than after a single session, because the survival of each area is hard to predict and the face carries the total.
Time adds a third. Once grafted fat has its own blood supply it behaves like the fat around it, and reports describe grafted fat enlarging with later weight gain. Across 103 studies, graft hypertrophy made up about 7% of reported adverse events, and contour irregularities about one in five.1 A face that looked balanced six months after grafting can therefore look heavier years later.
| Area | What patients notice | Often confused with |
|---|---|---|
| Cheeks | A wider, rounder face, heaviest when smiling; loss of the cheekbone line | Filler build-up, weight gain |
| Under the eyes | A ridge or fullness below the lower lid; puffiness that does not change through the day | Eye bags, fluid, under-eye filler |
| Temples and forehead | A domed or heavy upper face; a visible edge where the graft ends | Brow descent, filler |
| Nasolabial and jawline | Bulk beside the mouth or along the jaw that blurs the lower-face contour | Jowling, sagged fat |
| Any grafted area | A lump or uneven edge, sometimes firm | Fat necrosis, cysts, nodules |
Ageing, weight change and any filler added later affect the same areas, so not every heavy look after fat grafting is the graft itself. The assessment separates what is graft, what is filler and what is the face changing around them.
Many faces that have had fat transfer have also had filler, sometimes before, sometimes after and sometimes in the same areas. On the surface they can look alike, and they are corrected in completely different ways: hyaluronidase breaks down hyaluronic acid filler and does nothing to fat.
The first step is therefore working out what is actually there. A full treatment history is the starting point: which areas were grafted, how many times, and whether any filler or collagen stimulator was added. Ultrasound then shows what sits where and at what depth.4 Where hyaluronic acid filler is also present, it is dealt with separately through pillow face correction, which sometimes changes how much of the problem remains.
LCLR® stands for Laser Collagen Lipo Remodelling. It is the protocol Dr Sin Yong developed on a long-pulsed 755 nm and 1064 nm laser platform, and it has two arms. The collagen arm heats the dermis for tightening. The lipo-remodelling arm uses controlled bulk heating, through a Sculpting mode, on the superficial fat in zones he selects.
Grafted fat has no dissolving agent, so the same lipo-remodelling arm is used where a fat graft has been overfilled, has migrated from where it was placed, or has formed uneven areas. Zones are chosen from the ultrasound map, the depth and pass pattern are set per area, and the excess is reduced over a planned series rather than in one session. It is the treatment he reaches for first in these faces because it works on the excess from the surface, with no further injections and no incisions.
Response is gradual and varies between individuals. In clinic feedback patients describe the warmth during treatment as mild, and there is no redness or downtime afterwards; tenderness can occur where fat was targeted. Because removing fat from a face that is already lean would not help, the zones are kept to where the graft is in excess, and the plan is reviewed between sessions.
An overfilled graft is often not only a question of volume. Heavy cheeks can drag the mid-face down, and when the excess is reduced the skin over it may need support. VF Lift – Vertical Facelift is Dr Sin Yong’s protocol on Volnewmer 6.78 MHz monopolar radiofrequency, planned zone by zone along vertical vectors. It does three things in one plan: it lifts where tissue has descended, it sculpts pockets of puffiness, and it restores areas that are lean or hollow.
For patients who want more than reduction alone, the two are combined: Time Freeze Laser LCLR® works on the excess graft, and VF Lift lifts and contours the face around it. The order and spacing are set at review, and a face that is already lean is treated with restraint.
Microliposuction removes fat through fine cannulas and is one of the routes described for excess grafted fat, including MRI-guided removal in the forehead.3 It is surgery. In Singapore, microliposuction is liposuction for regulatory purposes: it may only be performed by doctors accredited under the Ministry of Health’s liposuction framework, in a hospital or an approved Ambulatory Surgical Centre, with a seven-day cooling-off period.5,6
Microliposuction tends to be considered when the excess is large, well defined and stable, or when a non-surgical series has not been enough. Where it is the right tool, Dr Sin Yong says so and refers you to an accredited surgeon; it is not offered as the first step for every heavy face. Direct excision is occasionally used for a discrete firm lump, and injections such as triamcinolone or deoxycholic acid have been described for small localised areas;2 both act on tissue and carry their own risks, including dents and skin thinning.
| Option | What it does | What it cannot do | Setting |
|---|---|---|---|
| Time Freeze Laser LCLR® | Reduces and reshapes excess superficial graft with controlled bulk heating, over a planned series | Remove a large deep excess in one step; replace surgery for marked skin excess | Clinic, no incisions, no downtime |
| VF Lift – Vertical Facelift | Lifts descended tissue, sculpts puffiness and restores lean areas with monopolar radiofrequency | Remove a discrete lump; it shapes rather than extracts | Clinic, no incisions |
| Microliposuction | Removes fat through fine cannulas | Avoid surgical risks such as dents, irregularity and bruising | Accredited surgeon, hospital or approved surgical centre |
| Excision | Removes a discrete firm lump directly | Treat diffuse fullness; it leaves a scar | Surgeon |
| Injections (triamcinolone, deoxycholic acid) | Act on small localised areas | Predictably treat large areas; can thin skin or leave dents | Doctor, used sparingly |
| Hyaluronidase | Dissolves hyaluronic acid filler | Dissolve fat. It has no effect on grafted fat | Clinic, after ultrasound mapping |
Swelling after fat grafting can take weeks to settle, and the graft continues to establish over the following months. Correction is generally considered only once the result has stabilised, which is one reason the first consultation is about assessment rather than treatment.
Gradual heaviness is rarely urgent. Increasing pain, redness, warmth or a hard, tender, growing lump after grafting is different and should be seen promptly, because inflammation, infection, cysts and fat necrosis are among the recognised causes. Any change in vision after an injection to the face needs urgent medical attention at once.
Dr Sin Yong takes the full history of grafting, filler and weight change, examines the face at rest and in movement, and uses ultrasound to show what is fat, what is filler and at what depth each sits.
Zones of excess graft are marked. The plan states what Time Freeze Laser LCLR® will be directed at, whether VF Lift is added, and what is better left alone or referred.
Excess graft is reduced over a planned series, with the depth and pass pattern set per zone. VF Lift, where included, is timed around it.
The face is reassessed between sessions so that only the excess is treated. If the excess is large and stable and a surgical route is better, that is said plainly and a referral is made.
The fee depends on the areas treated, the number of zones, which protocols are combined and how many sessions are planned. Fees are not published, because a figure given before an examination cannot reflect your situation. A written quote is given at consultation, and the consultation also decides whether treatment is advised at all. How fees are quoted.
Often, yes. Dr Sin Yong uses the lipo-remodelling arm of Time Freeze Laser LCLR® to reduce excess superficial graft from the surface over a planned series, with VF Lift added where lifting or contouring is wanted. Where the excess is large, deep and stable, surgical removal may be the better route and is discussed honestly.
No. Hyaluronidase dissolves hyaluronic acid filler only. Grafted fat that has taken is living tissue, so it is reduced with approaches that act on fat rather than dissolved.
LCLR® stands for Laser Collagen Lipo Remodelling. Its Sculpting mode applies controlled bulk heating to superficial fat in zones selected from the ultrasound map. In a face with excess graft, those zones are the areas of excess, and the reduction is gradual over a series.
VF Lift – Vertical Facelift lifts descended tissue, sculpts puffiness and restores lean areas with Volnewmer monopolar radiofrequency. It is added for patients who want more than reduction alone, particularly when heavy cheeks have weighed the mid-face down.
It is one of the routes described for excess grafted fat. In Singapore it counts as liposuction, so it is performed only by MOH-accredited doctors in a hospital or approved surgical centre, with a seven-day cooling-off period. Dr Sin Yong refers patients to an accredited surgeon when it is the right tool.
Until the result has stabilised. Swelling takes weeks to settle and the graft continues to establish over the following months, so assessment is not rushed.
Grafted fat behaves like the fat around it and has been reported to enlarge with weight gain. Ageing, weight change and any filler added later can also contribute, so each factor is assessed.
Irregularities are the most common contour complaint after facial fat grafting and many are harmless. A firm, red, tender or growing lump should be reviewed promptly, because fat necrosis, cysts and inflammation are recognised causes.
It can if too much is taken, which is why only the zones of excess are treated, the plan is reviewed between sessions, and a lean face is treated with restraint. Where support is needed, VF Lift restores lean areas.
No. Dr Sin Yong assesses and treats the after-effects without surgery. Fat grafting and liposuction are surgical procedures, and where they are needed he refers to an accredited surgeon.
