Quick Answer
Fat grafting (also called fat transfer or autologous fat transplantation) uses liposuction to harvest excess fat from one area of the body, processes it, and re-injects it into an area needing volume — using your own tissue rather than a synthetic implant or filler. It is used across the face, breasts, hands, and body for both rejuvenation and augmentation. The appeal is substantial: natural material, no foreign body, and the added benefit of improving the donor area through liposuction. The limitation is that fat survival is variable — typically 50–70% of transferred fat survives long-term — meaning results are less predictable than implants, and multiple sessions may be needed to achieve the target volume.
How Fat Grafting Works
The procedure involves three stages: harvest, processing, and placement.
Stage 1: Harvest
Fat is removed by liposuction from an area where the patient has sufficient excess — most commonly the abdomen, flanks, thighs, or inner knees. The harvesting technique matters for graft survival: low-pressure aspiration with small cannulas preserves more viable fat cells than aggressive high-pressure liposuction. The tumescent solution injected before harvest reduces trauma to the fat cells and minimises blood contamination.
Stage 2: Processing
The harvested fat contains fat cells (adipocytes), blood, tumescent fluid, and connective tissue debris. The fat must be processed before re-injection to remove these contaminants and concentrate the viable adipocytes. Processing methods include:
Centrifugation — the harvested fat is spun in a centrifuge to separate the fat layer from blood and fluid. The middle fat layer (highest concentration of viable cells) is used for grafting. This is the most widely used processing method.
Sedimentation (gravity separation) — the aspirate is allowed to settle by gravity, separating fat from fluid without mechanical processing. Less traumatic to fat cells than centrifugation but takes longer.
Washing — the fat is gently washed with sterile saline to remove blood and cellular debris.
The scientific consensus is that processing technique affects graft survival, but no single method has been definitively proven superior. The goal of all methods is to maximise viable fat cell concentration while minimising inflammatory contaminants.
Stage 3: Placement
Processed fat is injected through small cannulas in tiny aliquots — typically 0.1ml or less per pass — distributed across the recipient site in multiple passes at different depths and directions. This micro-aliquot technique (the Coleman technique) maximises the contact between each fat droplet and the surrounding tissue, which is essential for the new blood supply (neovascularisation) to form around each fat globule and keep the cells alive.
Placing fat in large boluses is the most common technical error in fat grafting — it produces fat necrosis (dead fat) in the centre of the bolus that cannot be vascularised, leading to hard lumps, cysts, and poor predictable survival.
Fat Survival: What to Expect
This is the most important variable to understand before fat grafting. Not all transferred fat survives. The cells that survive are nourished by in-growth of new blood vessels from the surrounding tissue (neovascularisation). Those that do not establish a new blood supply in the critical early weeks after transfer are reabsorbed by the body.
In experienced hands with good technique, approximately 50–70% of transferred fat survives long-term. This means:
- To achieve a final retained volume of 200ml in the breast, approximately 280–400ml must be transferred
- Initial over-correction is planned to account for expected resorption
- In the first weeks after grafting, the result looks more substantial than the final outcome as swelling adds to the perceived volume
Several factors affect fat survival:
- Technique — micro-aliquot placement in multiple layers maximises survival; poor technique significantly reduces it
- Recipient site vascularity — well-vascularised tissue supports graft survival; irradiated or scarred tissue is a poor environment
- Smoking — dramatically reduces neovascularisation and fat graft survival; smoking must stop well before and after surgery
- Patient health — adequate nutrition, good circulation, and absence of systemic disease support survival
- Compressive forces post-operatively — pressure on the grafted area in the first weeks can collapse the fragile new vessels; compression garments are typically avoided over grafted areas
Where Fat Grafting Is Used
Face — Facial Fat Grafting
The face loses volume in a predictable pattern with ageing — the temples hollow, the cheeks deflate, the tear troughs deepen, and the lips thin. Fat grafting to the face restores this volume with a natural, long-lasting result that fillers approach but cannot replicate in permanence.
Common facial fat grafting areas:
- Temples — one of the most ageing areas; fat restoration creates a fuller, more youthful upper face
- Cheeks and midface — restoring the high, rounded cheek projection lost with age
- Tear troughs — the under-eye hollow; fat is a natural alternative to filler in this area, with longer duration but a slower, more subtle correction
- Nasolabial folds — the groove from nose to mouth, caused partly by cheek volume loss
- Lips — a natural alternative to HA filler; longer-lasting but less precisely controllable
- Jawline — adding definition and fullness to a deflated lower face
Facial fat grafting requires very small volumes placed with precise, fine cannulas. The technique demands experience — the face is an unforgiving canvas where lumps, overcorrection, or poor survival produce obvious results. Results typically last years — longer than any HA filler — though some patients require a top-up session at 6–12 months as early resorption resolves.
Breast — Fat Transfer Breast Augmentation
Fat grafting to the breast offers a natural alternative to silicone implants for patients wanting modest enhancement — typically 100–250ml per breast, equating to approximately one cup size improvement. The appeal is no implant, no foreign material, and a natural feel.
Limitations of fat transfer for breast augmentation:
- Volume increase is limited by the recipient tissue capacity — over-injection into the breast causes fat necrosis and creates calcification visible on mammography
- Results are less predictable and reliable than implants — the volume outcome depends on fat survival, which varies
- Multiple sessions may be needed to achieve the target volume
- Patients must have adequate donor fat available
Fat transfer breast augmentation is appropriate for patients who want a small, natural enhancement, have adequate donor fat, and understand and accept the limitations in predictability compared to implants. It is not appropriate for patients wanting a reliable two-cup-size increase.
Fat grafting is also used in breast reconstruction after mastectomy — to improve the contour and add volume to reconstructed breasts over multiple sessions. In this context, it is an established and effective technique.
Buttocks — Brazilian Butt Lift (BBL)
Brazilian Butt Lift is fat transfer to the buttocks — one of the most popular body contouring procedures globally. Fat harvested from the flanks, abdomen, and thighs is transferred to the buttocks to increase projection, improve shape, and create better waist-to-hip proportion.
Safety in BBL is critically important. The most serious complication of BBL is fat embolism — fat entering gluteal vessels and reaching the lungs — which has a significant mortality rate if it occurs. Safe BBL technique involves injecting fat only in the subcutaneous (above the muscle) plane and not into or deep to the gluteal muscle, where vessels are most at risk. At Inform Clinic, Dr. Kalva strictly follows safety protocols that preclude deep injection.
Hands — Hand Rejuvenation
The dorsal (back of the) hand loses subcutaneous fat with ageing, making tendons and veins more prominent and creating a skeletal, aged appearance. Fat grafting to the hands restores the soft tissue cushion, covering tendons and vessels and creating a more youthful appearance. This is a straightforward, effective procedure with excellent longevity — one of the most underutilised fat grafting applications.
Fat Grafting vs Implants vs Fillers
Understanding the trade-offs between these three options helps patients make the right choice:
Fat grafting vs implants (for the breast):
- Fat: natural material, no foreign body, benefits donor site, modest volume limit, variable survival, multiple sessions may be needed
- Implants: reliable, predictable volume, excellent shape control, foreign material, implant-related risks (capsular contracture, rupture), designed for larger augmentation
Fat grafting vs fillers (for the face):
- Fat: your own tissue, longer lasting (years vs months), one procedure, recovery from liposuction required, slight unpredictability
- Fillers: immediate result, no recovery, fully reversible, requires repeated sessions every 9–18 months, cost accumulates over time
Neither option is universally superior — the right choice depends on the specific goal, the volume needed, the patient's preference for natural vs synthetic material, and their tolerance for surgical recovery.
What the Procedure Involves
Fat grafting is performed under local anaesthesia with sedation or general anaesthesia, depending on the volume of fat being harvested and the number of recipient areas being treated. A face-only fat graft from a small donor area can be performed under local anaesthesia; a full body fat transfer (BBL or breast) requires general anaesthesia.
Duration varies from 60 minutes (facial fat grafting with small harvest) to 3–4 hours (BBL or multi-area transfer). Day-care or overnight stay depending on extent.
Recovery
Recovery varies significantly based on the areas treated:
Donor site recovery (liposuction area): compression garment for 4–6 weeks, bruising and swelling 2–3 weeks, soreness 1–2 weeks.
Facial fat grafting: significant swelling in the first week, resolving to 70–80% of final result by 4–6 weeks. Patients typically return to social settings within 10–14 days.
Breast fat grafting: avoid underwired bra and compression over the breast for 4–6 weeks to avoid compressing the grafts. Swelling over the breast fades over 4–8 weeks as resorption and settling occur.
BBL: cannot sit directly on the buttocks for 6–8 weeks — sitting must be on the thighs or with a BBL cushion. This is the most inconvenient recovery aspect and must be planned for carefully in advance.
Risks Specific to Fat Grafting
- Fat necrosis — dead fat forming hard lumps; most common with bolus injection technique; usually resolves but occasionally requires aspiration
- Calcification — small calcium deposits forming at sites of fat necrosis, visible on imaging; not dangerous but can complicate future breast imaging
- Infection — uncommon with appropriate technique and prophylaxis
- Asymmetry — difference in survival between the two sides; may require a revision session
- Fat embolism (BBL-specific) — rare but serious; prevented by strict subcutaneous-only injection
Fat Grafting Cost in Hyderabad
Cost depends on the number of areas treated, the volume of harvest and transfer, and the duration and complexity of the procedure. Fat grafting is typically priced by site and volume rather than a flat fee. At Inform Clinic, a comprehensive quote is provided after consultation and physical assessment of the donor and recipient areas.
