Fat Grafting: More Than Just for Breast Enhancement | Hands, Buttocks, Face, Scar Correction

Updated on Sep 18, 2026

Fat grafting is a cosmetic procedure that removes a patient's own fat (usually from the belly, hips, or thighs) via liposuction, purifies it, and reinjects it into a target area (face, breast, buttocks, or hands) to add volume naturally. Because it uses the patient's own tissue rather than implants or fillers, it carries minimal rejection risk and doubles as body contouring for the donor site. Results appear immediately, with final volume settling over several weeks; surviving fat lasts for years once it establishes blood supply.

Key Takeaways

• It's a two-in-one procedure. Fat is harvested from a donor site (contouring it) and reinjected into a target area (enhancing it), all typically in a single session.
• Not all transferred fat survives, but what survives is generally permanent.
• It's irreversible, unlike dermal fillers which can be dissolved; grafted fat cells integrate permanently into tissue, so careful patient selection and technique matter.
• Since it's living tissue, grafted fat can grow or shrink with the patient's overall weight fluctuations.
• Recovery has area-specific rules such as avoiding sitting directly on the buttocks for a few weeks, avoiding underwire bras initially after breast grafting, and avoiding water/nail polish on hands for a while.
• General precautions include avoiding smoking and alcohol to protect fat survival.

What is fat grafting?

Fat grafting is a cosmetic procedure that transfers a patient's own fat from areas like the belly, hips, or thighs to enhance the face, breast, buttocks, or hands. Because it uses the patient's own tissue rather than implants or fillers, it produces natural-looking, long-lasting results with minimal risk of rejection.

Key benefits

• Uses the patient's own fat tissue, no foreign material, minimal rejection risk
• Removes unwanted fat from donor areas while enhancing target areas ("dual-purpose" contouring)
• Results are natural-looking and long-lasting
• Performed in a single session (harvest, purify, reinject)

Breast Fat Grafting in Singapore: How It Works

Breast fat grafting removes fat from a donor site (typically the belly, hips, or thighs) via liposuction, purifies it by centrifugation, then reinjects it into the breast to add volume, combining body contouring and breast enhancement in one procedure.

Procedure steps

1. Doctor identifies donor site (belly, hips, or thighs)
2. Fat is removed via liposuction
3. Extracted fat is centrifuged to purify it
4. Purified fat is reinjected into the breast to increase volume

Who is it for?

• Women seeking breast volume without implants
• Women who have lost breast volume after weight loss or breastfeeding
• Candidates with sufficient donor fat for harvesting

Is breast fat grafting the same process as buttock fat grafting?

Yes, buttock fat grafting follows the same surgical process (harvest, purify, reinject) and the same core candidacy requirements.

Facial Fat Grafting: Areas Treated and How It Works

Facial fat grafting uses small amounts of the patient's own fat, harvested via liposculpture from the waist, inner thigh, or belly, to restore volume and contour to the face, commonly the temples, cheeks, under-eyes, and chin.

Conditions it addresses

• Sunken or hollow cheeks
• Deep nasolabial folds (nose-to-mouth grooves)
• Dark under-eye circles
• Uneven or aged skin texture
• Deep, pitted acne scars

How it works

1. Small volumes of fat are harvested via liposculpture (waist, inner thigh, or belly)
2. Aspirated fat is processed
3. Purified fat is injected into targeted facial areas

According to Dr Ivan Puah, Medical Director of Amaris B. Clinic Singapore, fat distribution during injection is critical; the transferred fat needs to be surrounded by healthy tissue to maximise its survival rate and the final result.

Hand Fat Grafting: Reversing Signs of Ageing in the Hands

Hand fat grafting restores lost volume in ageing hands by harvesting the patient's own fat, purifying it, and reinjecting it beneath the skin of the hand to reduce the visibility of veins and tendons.

How it works

1. Fat is harvested via liposculpture
2. Fat is centrifuged to isolate pure fat cells
3. Purified fat is reinjected into the back of the hand at strategic points
4. The area is gently massaged for a smooth finish

Recovery: Recovery is typically quick, with swelling that gradually subsides; ice compression can help manage swelling.

Can Fat Grafting Fix Botched Liposuction or Surgical Scars?

Yes. Autologous fat grafting can correct post-surgical disfigurement, including botched liposuction. It can relax tension, soften scar tissue, and relieve pain caused by scar entrapment.

FAQ

When can I see fat grafting results?

You'll see visible enhancement immediately after the procedure. However, the treated area is deliberately overfilled by 20–30% to account for natural fat absorption during healing, with volume settling to its final result over the following weeks ^[1].

How long do fat grafting results last?

Roughly 25–50% of transferred fat is absorbed within the first 3–6 months; the fat that survives establishes its own blood supply and typically lasts for years ^[2]. Hand fat grafting has a higher survival rate of 50–70% ^[3].

Does weight change affect fat grafting results?

Yes. Because grafted fat is living tissue, it behaves like fat elsewhere in the body; it can expand with weight gain or shrink with significant weight loss. Maintaining a stable weight best preserves results.

How do I care for my hands after hand fat grafting?

Avoid straining your hands, submerging them in water (dishwashing, laundry, swimming, baths, saunas), and avoid nail polish or scented hand creams for at least 10 days post-procedure.

Can I sit down after buttock fat grafting?

Avoid sitting directly on the buttocks for at least three weeks to protect the grafted fat's blood supply. Use a donut/horseshoe cushion, rest on your stomach or side, and keep any necessary sitting brief.

Can I wear a bra after breast fat grafting?

Wear a soft, non-underwire crop top for the first two weeks, then transition to a supportive, thick-band, front-hook bra without underwire from week two onward.

Is fat grafting safe?

Yes, when performed by an experienced, qualified doctor. Because it uses the patient's own tissue, the risk of allergic reaction or rejection is virtually eliminated, and the donor site benefits from contouring at the same time.

How much pain or downtime should I expect from fat grafting?

Expect soreness, swelling, and bruising in both donor and recipient areas, generally well-managed with medication and easing within a week. Avoid strenuous exercise for 4–6 weeks; swelling typically peaks at 48–72 hours.

Where does the fat for fat grafting come from?

Common donor sites include the abdomen, inner or outer thighs, flanks (love handles), and hips, chosen based on the patient's anatomy and goals.

Can fat grafting give a large increase in breast size?

Fat grafting suits moderate breast enhancement, adding natural volume, correcting asymmetry, enhancing upper pole fullness, or reconstructing contour after a lumpectomy, rather than a dramatic size increase.

Will fat grafting leave scars?

Some scarring is possible with any incision-based procedure, but strategic incision placement in natural creases (e.g., the inframammary fold, gluteal crease), fine-instrument technique, and post-op silicone gel/sheet care minimise visibility.

What should I avoid after fat grafting?

Avoid smoking/vaping (which restricts blood flow and reduces fat survival), pressure on the grafted area (e.g., side-sleeping after facial grafting, tight bras after breast grafting), strenuous activity, and heat exposure (saunas, hot baths) until cleared.

Can facial fat grafting be reversed?

No. Unlike dermal fillers, which can be dissolved with hyaluronidase, fat grafting uses living fat cells that integrate permanently into tissue and cannot be reversed, making careful patient selection and precise technique essential.
