Understanding Facial Fat Grafting 

What is Facial Fat Grafting?

Facial fat grafting, also known as autologous fat transfer, involves harvesting fat cells from a donor site on your body—typically the abdomen, flanks, or thighs—and transferring them to areas of the face that have experienced volume loss. This surgical technique uses your own tissue, which eliminates concerns about allergic reactions or material compatibility.

Facial Anatomy and Age-Related Changes

The face contains two distinct layers of fat pads that provide structure and definition:

  • Superficial fat pads sit just beneath the skin in areas including the forehead, temples, cheeks, and around the eyes
  • Deep fat pads are located closer to bone and muscle, providing foundational support in the midface and orbital regions

As we age, both layers undergo atrophy and descent. Superficial fat pads shrink and migrate downward due to gravity and reduced skin elasticity, resulting in flattened cheeks, hollowing under the eyes, and pronounced nasolabial folds. Deep fat pads also diminish, contributing to a gaunt or sunken appearance in the midface and temples.

Technical Approach

Facial fat grafting addresses these changes through a three-stage process:

  1. Harvesting: Fat is extracted using gentle liposuction techniques designed to preserve cell viability
  2. Purification: The harvested fat undergoes centrifugation and cleansing to isolate healthy, viable fat cells
  3. Injection: Purified fat is carefully placed into targeted facial areas using fine cannulas and a layering technique

Treatment Areas

Common areas treated with facial fat grafting include:

  • Cheeks and midface
  • Under-eye hollows (tear troughs)
  • Nasolabial folds
  • Temples
  • Jawline
  • Lips
  • Chin
  • Forehead

Comparison to Other Techniques

Unlike temporary dermal fillers that require repeated treatments, facial fat grafting uses your own tissue and can provide longer-lasting results. The procedure also contains stem cells that contribute to improved skin texture. However, not all transferred fat cells survive the grafting process—typically 60-70% integrate successfully—which means some patients may benefit from additional sessions to achieve their desired outcome.

Am I a Suitable Candidate?

Ideal Patient Characteristics

Suitable candidates for facial fat grafting typically:

  • Are in good overall health without medical conditions that impair wound healing
  • Have realistic expectations about surgical outcomes
  • Maintain a stable weight
  • Have sufficient fat reserves in donor areas for harvesting
  • Experience facial volume loss or wish to enhance facial contours

Medical Considerations

Patients should disclose their complete medical history, including any medications, supplements, or underlying health conditions. Certain medical issues may affect surgical planning or recovery.

AHPRA Requirements

As of July 1, 2023, patients seeking cosmetic surgery in Australia must undergo a psychological assessment to ensure they are suitable candidates for surgery. This assessment helps determine emotional readiness and confirms realistic expectations.

Benefits of Facial Fat Grafting

  • Uses your own tissue, eliminating foreign material concerns
  • Can provide long-lasting results once integrated
  • Addresses multiple facial areas simultaneously
  • Minimal visible scarring due to small incisions
  • Provides body contouring benefits at the donor site
  • Contains stem cells that may enhance skin quality

How is Facial Fat Grafting Performed?

Facial fat grafting is performed under general anaesthesia in a fully accredited private hospital facility in Sydney, with continuous monitoring by a qualified anaesthetist throughout the procedure. The surgical duration typically ranges from 60 minutes, depending on the specific technique employed and whether additional procedures are performed concurrently.

Incision Locations and Approach

Small incisions (typically 3-4mm) are made at the donor site for fat harvesting and at strategic points on the face for fat injection. These incisions are placed to minimise visibility.

Step-by-Step Overview

  1. Harvesting Phase: Fat is collected from the predetermined donor site using specialised liposuction cannulas designed to minimise trauma to fat cells
  2. Processing Phase: The harvested fat undergoes centrifugation to separate viable fat cells from blood, oils, and other fluids. Only the healthiest fat cells are selected for transfer
  3. Injection Phase: Using fine cannulas, the surgeon carefully injects small amounts of purified fat into multiple tissue planes. This layering technique promotes even distribution and optimal cell survival
  4. Final Assessment: The surgeon evaluates facial symmetry and volume distribution before completing the procedure

Recovery and Aftercare

Facial fat grafting is typically performed as a day procedure, with most patients discharged the same day. Swelling and bruising at both the donor and facial sites are expected, peaking around days 2-3 before gradually improving. During the first week, patients should sleep with their head elevated, apply cold compresses as directed, and avoid strenuous activity. Most visible swelling and bruising resolve within 2-3 weeks, and patients can generally return to normal activities at the two-week mark. Sun protection is important during the healing period.

Final results become apparent over 3-6 months as swelling fully resolves and the transferred fat establishes a blood supply. Approximately 60-70% of grafted fat typically integrates successfully, with results varying based on individual healing, overall health, and lifestyle factors. Smoking, significant weight fluctuations, and sun exposure can all affect outcomes. Dr Turner schedules regular follow-up appointments to monitor healing and assess progress, with the first appointment typically occurring within one week of surgery. Some patients may choose a second grafting session to achieve additional volume if desired.

Risks and Complications

All surgical procedures carry inherent risks, and understanding these potential complications allows patients to make informed decisions. General surgical risks include infection at incision sites, bleeding or haematoma formation, adverse reactions to anaesthesia, scarring (typically minimal with this procedure), and nerve injury, which is usually temporary. Procedure-specific risks include fat reabsorption, in which some transferred fat cells do not survive; fat necrosis, in which cells may die and form firm lumps or cysts; asymmetry from uneven fat reabsorption; contour irregularities; calcification within transferred fat tissue; and poor integration with surrounding tissue.

These risks are minimised through thorough pre-operative medical assessment, sterile surgical technique in accredited facilities, gentle fat harvesting to preserve cell viability, and precise injection using small amounts in multiple layers: comprehensive post-operative care instructions and regular follow-up monitoring further support safe outcomes. Patients should contact Dr Turner’s rooms immediately if they experience signs of infection, such as fever, increased pain, redness or discharge, excessive swelling on one side of the face, severe or worsening pain not controlled by prescribed medication, or any other concerns about their recovery.

Individual results will vary from patient to patient and depend on factors such as genetics, age, diet, and exercise. All invasive surgery carries risk and requires a recovery period and care regimen.
