Fat grafting (autologous fat transfer) is an elegant surgical technique that harvests fat from one area of your body—typically abdomen, thighs, or flanks—and carefully transfers it to areas requiring volume restoration or enhancement. This natural approach to facial rejuvenation and body contouring uses your own tissue, eliminating rejection risk whilst providing soft, natural-feeling results. Beyond simple volume replacement, fat grafting improves skin quality, provides permanent enhancement (once fat survives initial healing), and offers the additional benefit of body contouring at the donor site.

What Is Fat Grafting?
Fat grafting involves three key steps: harvesting fat from donor sites using gentle liposuction, processing and purifying the harvested fat (removing blood, oil, damaged cells), and precisely injecting purified fat into recipient areas requiring volume or enhancement. This autologous (your own tissue) approach offers unique advantages including complete biocompatibility (no rejection or allergic reactions), natural appearance and feel (living tissue that moves naturally), permanence once fat survives (unlike temporary fillers), regenerative properties (stem cells and growth factors improve skin quality), and dual benefit of contouring donor site whilst enhancing recipient area.
Fat Survival and Permanence
Not all transferred fat survives. Approximately 40-60% of grafted fat establishes blood supply and survives permanently; the remainder is reabsorbed by the body during the first 3-6 months. Surviving fat remains permanently, behaving like normal fat tissue—it can gain or lose volume with weight changes but doesn’t disappear. Surgeons typically slightly overcorrect initially, anticipating this resorption. Some patients require secondary grafting sessions to achieve optimal volume.
Applications and Treatment Areas
Facial Fat Grafting
Midface/Cheek Restoration: Restores youthful cheek fullness and elevation lost with ageing, creating lifted, rejuvenated appearance. This is one of the most common and effective fat grafting applications.
Under-Eye Hollows: Fills tear trough depressions, reducing dark circles and tired appearance. Requires expert technique given delicate area.
Temples: Restores volume to hollow temples, common with ageing, improving facial balance and reducing gaunt appearance.
Nasolabial Folds and Marionette Lines: Softens deep facial folds, though results are more subtle than with dermal fillers in these dynamic areas.
Lips: Provides natural lip enhancement with permanent results, though technique is challenging and results less predictable than hyaluronic acid fillers.
Overall Facial Rejuvenation: Multiple areas treated simultaneously create comprehensive facial volume restoration, often combined with facelift surgery for optimal rejuvenation addressing both structural laxity and volume loss.
Hands
Fat grafting rejuvenates aged hands by restoring volume, minimizing visible tendons and veins, and improving skin quality—creating more youthful hand appearance.
Scar Revision and Contour Irregularities
Fat grafting improves depressed scars, fills contour deformities from previous surgery or trauma, and enhances skin quality in damaged areas through regenerative properties.
Ideal Candidates for Fat Grafting
Ideal candidates include those with facial volume loss from ageing, weight loss, or genetics seeking natural, long-lasting correction, sufficient donor fat for harvesting (lean patients may have inadequate fat), good general health without bleeding disorders or healing problems, realistic expectations about fat survival rates and potential need for multiple sessions, non-smokers or willing to stop (smoking dramatically reduces fat survival), and stable weight (significant weight changes affect results).
When Fat Grafting May Not Be Ideal
Very thin patients may lack adequate donor fat. Patients seeking precise, predictable volume may prefer hyaluronic acid fillers (more controllable, immediate final result). Those unable to accept potential need for secondary grafting may prefer fillers. Smokers unwilling to stop have poor fat survival rates. For small volume additions, fillers may be more appropriate; fat grafting suits moderate to large volume restoration.
The Fat Grafting Procedure
Fat grafting is performed under local anaesthesia with sedation or general anaesthesia depending on extent. The procedure takes 1-3 hours.
Fat Harvesting
Donor sites (typically abdomen, flanks, thighs) are identified and marked. Small incisions are made and tumescent fluid (saline with local anaesthetic and adrenaline) is infused. Fat is gently harvested using small liposuction cannulas with low suction to minimize fat cell trauma. Approximately 50-100ml of fat is typically harvested, though this varies by treatment plan.
Fat Processing
Harvested fat undergoes processing to remove blood, oil, and damaged cells. Methods include centrifugation (spinning to separate components) or filtration/washing. This yields purified, concentrated fat ready for injection.
Fat Injection
Purified fat is loaded into small syringes. Using specialized cannulas, fat is injected in multiple tiny parcels throughout recipient areas in different tissue planes. This micro-droplet technique (many small deposits rather than large boluses) maximizes fat survival by ensuring each parcel contacts blood supply. Overcorrection (slightly more volume than desired final result) accounts for expected resorption.
Closure and Dressing
Small incisions are closed with sutures or left to heal naturally. Dressings are applied to donor and recipient sites. Compression garment may be worn at donor site for 2-4 weeks.
Recovery and Results
Recovery Timeline
Swelling and bruising are significant initially, most pronounced in first week. Donor sites experience soreness similar to liposuction recovery. Most patients return to work within 1-2 weeks. Strenuous activity avoided for 4 weeks. Swelling gradually resolves over 3-6 months with final results apparent once all resorption complete. During this time, volume decreases as non-surviving fat reabsorbs.
Results and Longevity
Final results emerge at 3-6 months once all resorption complete and surviving fat stabilizes. Approximately 40-60% of transferred volume remains permanently. Surviving fat behaves as normal tissue—it can fluctuate with weight changes but doesn’t disappear. Results are natural-appearing with soft, living tissue that moves naturally. Skin quality often improves due to stem cells and growth factors in transferred fat. Some patients require secondary grafting sessions to achieve optimal volume.
Advantages Over Fillers
Fat grafting offers permanent results once fat survives (unlike temporary fillers), natural living tissue (not synthetic product), improves skin quality beyond volume alone, dual benefit of donor site contouring, and cost-effective for large volume restoration (multiple filler syringes expensive; single fat grafting procedure more economical).
Specialist Technique and Expertise
Fat grafting demands exceptional surgical skill, aesthetic judgement, and experience. Success depends on gentle fat harvesting preserving cell viability, meticulous processing techniques, precise injection technique maximizing survival, appropriate volume assessment accounting for resorption, and comprehensive facial anatomy understanding.

Frequently Asked Questions
Is fat grafting permanent?
Yes and no. Approximately 40-60% of transferred fat establishes blood supply and survives permanently, behaving like normal fat tissue. The remainder is reabsorbed by the body during the first 3-6 months. Surviving fat remains permanently (unlike temporary fillers) but can fluctuate with weight changes—gaining volume if you gain weight, losing volume if you lose weight. Some patients require secondary grafting sessions to achieve desired volume. Once stabilized, results are long-lasting.
How does fat grafting compare to dermal fillers?
Fat grafting offers permanent results (surviving fat remains indefinitely), natural living tissue, improved skin quality from regenerative properties, and cost-effectiveness for large volume restoration. However, it requires surgery with recovery time, has less predictable volume (due to resorption rates), may require multiple sessions, and involves two surgical sites (donor and recipient). Fillers provide immediate, predictable results with no downtime but are temporary (6-18 months), require ongoing maintenance, and become expensive for large volumes. Many patients use both—fillers for precise areas, fat grafting for large volume restoration.
Will I need more than one fat grafting session?
Many patients achieve desired results with single session, but approximately 30-40% benefit from secondary grafting to achieve optimal volume. This is particularly true for large volume restoration or areas with poor blood supply (like lips). The need for secondary grafting cannot be predicted definitively beforehand, as fat survival rates vary individually. Most surgeons initially overcorrect slightly, anticipating resorption, but some patients require additional grafting once final results apparent at 3-6 months. This staged approach allows gradual, controlled enhancement.
