Fat grafting versus dermal fillers comes down to where the procedure happens and whether it can be undone. Fat grafting is a surgical transfer of the patient's own fat, with donor-site work and variable graft survival; dermal fillers are placed in clinic in staged amounts, and hyaluronic acid filler can be dissolved with hyaluronidase.
Fat grafting harvests the patient's own fat, processes it and re-injects it into deflated facial compartments — a surgical procedure with donor-site work, variable graft survival and results that are largely permanent where the fat takes. Dermal fillers place manufactured volume — hyaluronic-acid gels, or collagen-stimulating products such as Radiesse and Ellanse — through a needle or cannula in clinic, adjustable in small staged amounts. Both can restore a hollow; they differ in everything around that fact.
“Permanence commits today's judgment to a moving target. A dissolvable filler lets the plan evolve with the face.”
— Dr Sin Yong
Fat behaves like living tissue: it can gain and lose weight with you, survival is not fully predictable, and correcting an over-grafted area means surgery again. HA filler behaves like a considered product: predictable placement, staged millimetres, and — its defining property — reversibility. If a placement is wrong, migrates or simply is not wanted, hyaluronidase (hyalase) dissolves it. That reversal pathway is a clinical discipline of its own, covered on the filler correction page, and the wider volume strategy on volume restoration and sunken face treatment — where lifting descended fat often shrinks the volume question before either tool is chosen.
Permanence sounds like the premium option until a face changes — and faces change. Weight shifts, tissue descends, taste matures. An adjustable, dissolvable material lets the plan evolve with the face; a permanent graft commits today's judgment to a moving target. There are faces where grafting is genuinely the right tool — large-volume reconstruction, filler-exhausted cases — and those are referred to the appropriate specialist honestly. For most aesthetic volume work, staged and reversible wins on safety of judgment, not just safety of procedure.
Fat grafting and dermal fillers both restore facial volume: grafting is surgical with variable survival and near-permanence, while hyaluronic-acid fillers are staged, adjustable and reversible with hyaluronidase — a clinical advantage, not a consolation; at Dr Sin Yong's Singapore practice the choice follows assessment, with grafting referred where genuinely indicated.

People wanting one fixed, single-visit result, or whose face has descended rather than lost volume, tend to respond poorly to either tool and need lifting or referral considered first.
Expected effects after filler are temporary bruising, swelling, tenderness and small lumps that settle. Uncommon complications include asymmetry, an overfilled look, lumps or nodules, infection, and a vascular event, which needs urgent attention. Hyaluronic acid can be dissolved with hyaluronidase if a placement is wrong; Radiesse and Ellansé cannot, so reversibility is weighed when the material is chosen. Fat grafting adds surgical and donor-site risks, unpredictable survival and weight-linked change, and correcting an over-grafted area means surgery again. Risk is reduced by assessing first, using small staged amounts and reviewing before adding more.
The fee for filler depends on what your assessment finds: which compartments are deflated, and whether volume is lost or has simply descended. It reflects the areas treated, the material chosen, whether hyaluronic acid, Radiesse or Ellansé, the amount placed in each staged visit, and whether lifting is combined first. A written quote is given at consultation, after examination. Fat grafting is quoted separately by the surgical team it is referred to. The consultation decides whether treatment is advised at all.
How quotes work at this practice: how we quote.
Grafted fat is living tissue whose survival cannot be fully predicted, and it gains and loses weight with you.
Hyaluronic acid filler can be dissolved with hyaluronidase; Radiesse, Ellansé and grafted fat cannot.
Hyaluronic acid filler can be dissolved with hyaluronidase, also called hyalase, if a placement is wrong, migrates or is simply not wanted. Grafted fat and collagen-stimulating fillers such as Radiesse and Ellansé cannot be dissolved this way, which is why reversibility is weighed when choosing a material.
No. Fat grafting is a surgical procedure with donor-site work, and it is referred on where it is genuinely indicated, such as large-volume reconstruction or filler-exhausted cases. In clinic, volume is restored with hyaluronic acid filler, Radiesse or Ellansé, placed in small staged amounts.
Fat grafting harvests the patient's own fat, processes it and re-injects it into deflated facial compartments as a surgical procedure. Dermal fillers are manufactured products, either hyaluronic acid gels or collagen-stimulating products, placed in clinic through a needle or cannula and adjusted in staged amounts.
Grafted fat is living tissue, so how much survives cannot be fully predicted. It also gains and loses weight with you, and correcting an over-grafted area means surgery again. A staged, adjustable filler plan lets the approach change as the face changes.
Whether volume is truly lost or has descended is checked before any filler or graft is considered. Where tissue has descended, lifting may be considered first, because it can change the volume question before either tool is chosen. Assessment separates the two.
Filler cost follows the plan, not a list. It depends on which compartments are deflated, the material chosen (hyaluronic acid, Radiesse or Ellansé), the areas and amounts placed, and whether lifting comes first. A written quote is given at consultation, after examination. Fat grafting is surgical, is referred on, and is quoted separately by the team performing it.
Staged fillers tend to suit people who want small, adjustable changes and value reversibility with hyaluronidase for hyaluronic acid. Fat grafting is a surgical option for large-volume reconstruction or filler-exhausted faces, and is referred on. Neither suits a face where tissue has descended and lifting should come first. Assessment decides.
No duration can be promised for either. Grafted fat is living tissue, so how much survives is unpredictable and changes as you gain or lose weight. Filler longevity depends on the material, the area, your metabolism and anatomy. Review timing and any repeat visit are set at consultation and adjusted to how the face responds.
Fat grafting involves surgery and donor-site work, unpredictable survival and weight-linked change, and correcting over-grafting means more surgery. Fillers are temporary and may need repeat visits, can cause bruising, lumps, an overfilled look or, uncommonly, vascular problems, and Radiesse and Ellansé cannot be dissolved. Both fail when used for descent rather than lost volume.
Lifting, filling, grafting or nothing — the honest comparison is made on your face, not in general.
