Face fat grafting in Korea: the number nobody quotes you is how much of it stays
Written by KCODI medical interpreter team · English deskUpdated · 9 min read
Face fat grafting in Korea gets pitched as the natural option. It is your own tissue, so nothing foreign goes in, and one operation can soften temples, cheeks, the forehead and the area under the eyes at once.
All of that is true. What the consultation usually skips is the only number that decides whether you are pleased at the six-month mark: how much of the transferred fat is still there. Published reviews put the average at roughly half, with a very wide spread.
Interpreters hear the disappointed version of this conversation months later, over a messaging app. So here is the honest shape of the operation, what moves retention, and how it sits next to fat removal, which patients often confuse with it.
What the operation actually is
Fat is taken by gentle liposuction, usually from the thigh or abdomen, processed, and injected in small amounts through fine cannulas into the face. Seoul clinics sell it under several names: fat grafting, fat transfer, micro fat, nano fat, and versions that claim extra processing steps.
The names matter less than three practical facts. There is a second surgical site, on your leg or abdomen, that also bruises. It is done under sedation or general anaesthetic, not as a lunchtime treatment. And it is frequently combined with something else, most often contouring or a lift, which is why it turns up as a line on a bigger quote.
The stay length and price range for the operations it is combined with sit on the facelift and facial contouring pages, and the fat harvesting side is the same technique described on the liposuction page.
Retention: the number to ask about
A systematic review and meta-analysis of 27 studies covering 1,011 patients with facial fat grafting pooled the volume retention rate at 47 per cent, with a confidence interval of 41 to 53 per cent. Individual studies ranged from 26 to 83 per cent, and the authors' conclusion was blunt: the exact percentage retained is currently unpredictable.
| Finding | What it means when you book |
|---|---|
| Pooled retention around 47 per cent | Assume roughly half the injected volume is gone at the end of the settling period |
| Range across studies 26 to 83 per cent | No surgeon can promise your number, and one who does is guessing |
| Measurement method changes the reported figure | Before-and-after photos overstate retention; ask what the surgeon means by success |
| Complications reported in about 2.8 per cent of patients in that review | Uncommon, not zero, and the serious ones are vascular |
This is why Seoul surgeons often overfill slightly at the first operation, and why a second, smaller session is standard rather than a sign that something went wrong. Ask at the first consultation whether a second round is expected, what it would cost, and how long the wait is. Getting that answer before surgery changes how the six-month mark feels.
Adding fat, removing fat, and the under-eye
Patients arrive having read about both grafting and removal and are not sure which they want. They are opposite operations aimed at different faces.
- Fat grafting adds volume to areas that have gone flat or hollow: temples, upper cheeks, forehead, the groove under the eye.
- Buccal fat removal in Korea takes a defined pad out of the lower cheek to make the mid-face look narrower. It cannot be undone, and surgeons are increasingly cautious with younger patients because faces lose volume there with age anyway.
- Korean under-eye fat work is a third thing again. The bulge under a lower eyelid is usually fat that has moved forward, and repositioning it is a different operation from injecting more fat in. Our under-eye fat repositioning page covers it.
- Filler does the adding job without surgery and without a donor site, and is reversible when hyaluronic acid is used. It also wears off. See Korean filler brands.
A consultation that starts by deciding which of those four your face needs is worth more than a price comparison between clinics offering the same word.
Risks, stated plainly
A systematic review of complications in facial fat grafting grouped them into three tiers. Minor ones, prolonged swelling or redness, need no treatment. Moderate ones, lumps, irregularity, asymmetry, fat necrosis or an over-filled area, may need a second operation to correct. Severe ones, where fat enters a blood vessel, are rare and serious.
The same review made a point worth repeating: the true complication rate is not well established, because reporting is inconsistent across studies. Treat any clinic quoting you a precise safety percentage with scepticism.
Practical consequences for you: ask who injects, ask about the cannula technique used around the eyes and the glabella, and take the swelling timeline seriously rather than booking a flight for day three.
The trip, in order
- Consultation with an examination, and a plan that names every area being treated.
- Surgery, under sedation or general anaesthetic, with the donor site chosen with you.
- The swollen days: the face looks fuller than the result, sometimes much fuller. This is expected and not the outcome.
- A review before you fly, with photos taken at the clinic so there is a baseline.
- The settling period at home, over months, during which volume drops.
- The honest assessment, and the second-session conversation if one is needed.
Step three is where patients panic and step five is where they get quiet. Knowing both are normal is most of the benefit of reading this before booking.
