What Facial Fat Grafting Treats
지방이식 (jibang isik, literally “fat transplant” — used in Korean clinics to refer to autologous fat grafting) addresses facial volume loss that cannot be resolved by skin tightening or lifting alone. As the face ages, subcutaneous fat compartments atrophy unevenly, producing hollowing in predictable anatomical zones. Fat grafting replenishes those depleted compartments with the patient’s own living fat cells.
The six areas treated most frequently in Korean practice are summarized below.
| Area | What fat grafting achieves | Alternative treatment | Graft survival note |
|---|---|---|---|
| Under-eye hollowing (tear trough) | Fills the infraorbital hollow; reduces shadowing and the appearance of dark circles caused by volume deficit | Hyaluronic acid filler (temporary) | High-precision zone; micro-fat preferred; survival 60–70% |
| Temporal hollowing | Restores lateral brow and temple fullness lost to temporal fat pad atrophy | Filler (temporary); brow lift (positional only) | Deep plane injection; survival 60–70% |
| Cheek deflation | Re-establishes malar projection and midface convexity reduced by cheek fat pad descent and atrophy | Cheek filler; cheek implant (permanent but alloplastic) | Largest volume zone; 60–70% survival; over-injection standard |
| Nasolabial fold | Reduces fold depth by restoring volume in the deflated medial cheek above the fold — not by filling the fold itself | Filler (direct); facelift (repositioning) | Adjunct to midface volume; survival 60–70% |
| Lip volume loss | Adds subtle volume to the vermilion body and restores lip-to-face proportion thinned by aging | Lip filler (temporary and reversible) | Fine-canula technique required; survival variable, 50–65% |
| Temple | Fills superior temporal fossa hollowing that exposes the temporal bone contour | Filler (off-label, high-risk zone) | Good survival when placed at correct depth; 60–70% |
Understanding which zone is being treated matters for setting expectations: a surgeon injecting into the deep malar fat pad is solving a different anatomical problem than one addressing the tear trough with micro-fat. Confirm the target zones and technique in your pre-operative consultation.
Candidacy: Who Benefits from Fat Grafting
Fat grafting is not a universal rejuvenation procedure. It corrects volume deficit — not skin laxity, not surface texture alone, not structural bone changes. The best candidates present with measurable soft-tissue volume loss in specific compartments and have realistic expectations about the 3–6 month graft stabilization period.
Korea’s approximately 2,100 board-certified plastic surgeons¹ are required by law to hold Korean Society of Plastic and Reconstructive Surgeons (KSPRS; 대한성형외과학회, Daehan Seonghyeong Oegwa Haghoe — South Korea’s official certification and professional board for plastic surgeons)² certification to perform surgical fat grafting legally.² Patients can verify a surgeon’s certification directly on the KSPRS public registry.³
Often a good candidate
- Adults 30+ presenting with visible facial volume loss: under-eye hollowing, flat or deflated cheeks, deep tear troughs, temporal hollowing
- Patients combining fat grafting with facelift — restoring volume while lifting repositions tissue produces more balanced outcomes than either alone
- Patients combining fat grafting with rhinoplasty — midface and under-eye volume correction complements nasal refinement in a single operative session
- Patients with sufficient donor fat available at the abdomen, inner thigh, or flank for harvest (typically 20–60 mL harvested for facial use)
- Non-smokers or patients who have ceased smoking at least 4 weeks pre-operatively — smoking impairs graft vascularization and survival
Should reconsider or wait
- Very low body fat patients: insufficient donor volume limits how much can be harvested without visible donor-site deformity
- Patients expecting 100% graft survival: reabsorption of 30–40% is normal and planned for — surgeons over-inject to compensate
- Patients wanting immediate permanent results: the final result is not visible until 3–6 months post-procedure when graft stabilization is complete
- Patients with active skin infections or inflammatory conditions in the planned injection zones
Not a suitable candidate
- Patients actively losing weight or planning significant weight loss post-procedure — grafted fat responds to weight changes exactly as native fat does, and weight loss after grafting will reduce transferred volume
- Patients expecting fat grafting alone to produce a facelift-equivalent result — volume restoration does not correct ptosis (tissue descent) or skin laxity
- Patients with unrealistic expectations of dramatic facial transformation from fat grafting as a standalone procedure
The Fat Grafting Procedure: Harvest, Processing, Injection
Korean surgeons perform facial fat grafting in three sequential phases: harvest, processing, and injection. Each phase directly affects how much transferred fat survives.
Harvest. The surgeon makes a 2–3 mm incision at the donor site — most commonly the lower abdomen, inner thigh, or flank — and inserts a blunt-tipped cannula (a thin hollow tube) connected to a syringe or low-pressure suction device. Low-pressure harvest is standard because high-vacuum suction mechanically damages fat cell membranes, reducing viability. Typical harvest volume for full facial fat grafting is 40–80 mL of raw lipoaspirate, which yields 20–40 mL of processed fat after the next phase.
Processing. Harvested lipoaspirate contains a mixture of viable fat cells, oil (from ruptured cells), blood, local anesthetic, and tissue fluid. These must be separated before injection. The two most common methods are centrifugation (spinning the syringe at 1,200–3,000 RPM for 3 minutes to separate layers by density) and sedimentation (allowing gravity separation over several minutes). After processing, the surgeon draws off the aqueous lower layer and oil upper layer, leaving the consolidated fat in the middle.
Micro-fat and nano-fat are produced at this stage: micro-fat is processed through progressively finer cannulas (500–600 µm internal diameter) to reduce parcel size for delicate zones; nano-fat is further emulsified — fat cells are disrupted and the resulting product is filtered to a near-liquid suspension used for superficial skin-quality improvement rather than volume.
Injection. Processed fat is loaded into 1 mL syringes and injected in multiple small passes using blunt cannulas at varying depths within the target compartment. Small-parcel, multi-plane injection distributes fat in close proximity to the blood supply — essential for revascularization (the process by which transferred fat cells establish a new blood supply to survive). Total operative time for standalone facial fat grafting is 60–90 minutes under local anesthesia with sedation or light general anesthesia.
Graft Survival: What the Evidence Says
Not all transferred fat survives. A portion undergoes reabsorption — broken-down fat cells are metabolized by the body — over the first 3–6 months. The fat that establishes a blood supply (revascularizes) within the recipient tissue becomes permanent; the remainder does not.
The reported long-term survival rate for facial fat grafting is 60–70%. This figure reflects the proportion of transferred volume remaining at 6–12 months post-procedure. Korean surgeons account for expected reabsorption by over-injecting 20–30% beyond the target final volume. This means patients appear overfilled for the first 4–8 weeks — a normal finding, not a complication.
Three factors most strongly influence whether a graft survives:
- Harvesting technique — low-pressure atraumatic harvest preserves fat cell membrane integrity; aggressive suction reduces viability before injection begins.
- Processing method — centrifugation at appropriate speed separates non-viable material while preserving fat cell architecture; over-centrifugation damages cells.
- Injection parcel size — smaller parcels placed in close contact with well-vascularized tissue survive at higher rates; large bolus injections placed in avascular planes have poor survival and risk fat necrosis (death of fat tissue producing firm lumps called oil cysts).
Fat necrosis producing palpable or visible lumps is the primary quality complication in fat grafting. It is more common with inexperienced technique, large-volume single-session injections, or injection into previously scarred tissue. Patients should confirm their surgeon’s approach to parcel sizing and injection plane before proceeding.
Why Koreans Frequently Combine with Facelift
A facelift — called 안면거상술 (anmyeon georangsul, face-lifting surgery) in Korean — repositions ptosed (descended) facial tissue and removes skin redundancy. What it cannot do is replace the fat volume that atrophied as part of the aging process. A facelift performed without volume restoration on a face with significant fat compartment atrophy can produce a tightened but hollow, “skeletonized” appearance — tissue is repositioned but the underlying volume deficit remains visible.
Korean surgeons combine fat grafting with facelift to address both components of facial aging simultaneously: structural descent corrected by lifting, and volume deficit corrected by fat transfer. This combination is well-established in Korean practice and is a significant driver of the high volume of facial fat grafting performed in Gangnam’s specialist clinics.
The practical logistics favor combination: both procedures require the same general anesthesia session, and fat grafting adds 30–60 minutes to total operative time. Recovery timelines overlap — the swelling from fat grafting resolves within the same window as facelift recovery (2–4 weeks for social presentability, 3–6 months for final fat graft result).
Cost for combined facelift and fat grafting in Korea ranges from ₩7–18M (≈$5,200–13,300 / ≈AUD$7,900–20,400), a meaningful premium over standalone facelift (₩5–12M) but less than the two procedures priced separately. All price data: FX rate July 2026 (1 USD = ₩1,350; 1 AUD = ₩880).
How long does facial fat grafting last in Korea?
The fat that survives the initial reabsorption period (3–6 months) is permanent — it behaves like your native facial fat. The typical 60–70% graft survival rate means what remains after 6 months stays. However, ongoing facial aging will continue to affect the grafted fat over time, as it is living tissue subject to the same volume loss mechanisms as native fat. Most patients see 5–10+ year durability from a well-executed fat grafting session.
Is fat grafting better than filler for the face in Korea?
Fat grafting uses your own tissue and produces permanent results; filler is temporary (6–18 months per treatment) but predictable and reversible. Fat grafting requires surgery, a donor site (small liposuction), and 3–6 months for graft stabilization. Filler is office-based and immediate. Korean surgeons typically recommend filler for patients under 40 with minor volume needs and fat grafting for more significant volume restoration, for patients combining with other surgery, or for patients seeking permanent correction.
What is the difference between micro-fat and nano-fat grafting?
Standard fat grafting transfers fat parcels for volume restoration. Micro-fat uses smaller parcels (processed through finer canulas) for more precise injection in areas requiring detail, such as the tear trough. Nano-fat is fat emulsified to near-liquid consistency — it cannot add volume but is injected superficially to improve skin quality, texture, and fine lines. Korean surgeons often use a combination: standard or micro-fat for deep volume and nano-fat superficially for skin texture.
Can fat grafting be combined with rhinoplasty in Korea?
Yes — fat grafting to the midface and under-eye area is commonly combined with rhinoplasty in Korea. The two procedures operate on different areas and can be performed in a single anesthesia session with total operative time of 2–3 hours. Adding fat grafting to a rhinoplasty trip requires no extension of the minimum Seoul stay (both share a 10-day minimum). Discuss donor site planning (abdomen vs thigh) with your surgeon pre-operatively.
