Facial Fat Grafting Guide — From Survival Rate to Swelling Timeline & Stay Plan

Who it suits / who should be cautious

Facial fat grafting takes a small amount of fat from your own body (mainly thighs or abdomen), purifies it, and places it into hollow areas of the face. Many people choose it because it uses your own tissue rather than a foreign material, and fat that takes hold can last a long time.

• People whose broad areas such as the forehead, temples or front cheeks are hollow, making the face look tired or older
• People who want one long-lasting approach rather than repeating filler again and again
• People who prefer to restore volume with their own tissue instead of a foreign material
• People who can stay in Korea for about 5–7 days and allow for 1–2 weeks of swelling

How Fat Grafting Works — Harvest, Purify, Inject in 3 Steps

Fat grafting happens in three main steps. How carefully each step is done affects graft survival (fat living and settling in) and how smooth the result looks.

The 3 steps

Uses and cautions by area

Fat is good at softly filling large areas. It is not suited to building a sharp shape, like a defined nose tip.

What Is Survival Rate? — Not All the Fat Stays

Transferred fat must connect to new blood vessels in its new spot to survive. Some is absorbed and lost in the process, and the share that survives is called the survival rate. It varies widely by study, area and body type, and it is generally planned on the basis that only part of the amount placed will remain.

• Most of the fat that will remain is usually settled by about 3 months after the procedure.
• Areas with little movement, such as the forehead and temples, tend to hold fat relatively well, while areas with lots of expression movement tend to hold less.
• Smoking, strong pressure or massage right after the procedure, and rapid weight loss all work against survival.
• Any shortfall is usually topped up with a second session 3–6 months later, and some people plan for two sessions from the start.

Fat Grafting vs Hyaluronic Acid Filler

The two share similar goals but have different characters. Depending on the area and your schedule, you may use just one, or both together.

Be careful with the terms “micro-fat” and “stem cells”

• “Micro-fat” refers to processing fat into smaller particles to place in thin areas, and the standard differs by clinic. What matters more than the name is which area it is used in and how it is placed.
• The phrase “stem cell fat grafting” often emphasizes cell components naturally found in fat. It is hard to treat as proof of a guaranteed survival rate or skin improvement, and treatments that culture cells separately require separate approval.
• Claims like “guaranteed ○○% survival” or “permanent in one session” are likely exaggerated, so judge them carefully.

What Happens on the Day

1. 1
   In-person consultation and design (about 30 minutes to 1 hour): the doctor looks at your face, decides the areas, amounts and harvest site, and marks them with a pen. Your manager interprets.
2. 2
   Tests and preparationif you are having sleep anesthesia, simple tests and fasting instructions are checked.
3. 3
   Harvest (about 20–30 minutes)the needed amount of fat is drawn through a small opening in the thigh, abdomen or similar area.
4. 4
   Purify and inject (about 40 minutes to 1 hour): the filtered fat is placed in small amounts across several layers of the face.
5. 5
   Recovery and heading back (about 1 hour)after waking from anesthesia you get cold compresses and aftercare instructions, then go to your accommodation. If you had sleep anesthesia, do not travel alone.

Swelling and Bruising — Day by Day

Fat grafting causes more swelling than filler, and it lasts longer. The early look is not the final result, so it is important not to rush.

• Day 0–3
  Swelling is at its peak. The face may look puffy and bruised, and the harvest site also has bruising and tightness.
• Day 4–7
  The main swelling starts to go down. Light outings are possible with a mask and hat, and bruises fade to a pale yellow.
• Weeks 1–2
  Most of the major swelling and bruising settles, making daily life and makeup easier. It may still look slightly overdone.
• Months 1–3
  Lingering swelling clears, some fat is absorbed and the shape settles.
• After 3 months
  Most of the remaining fat has settled. From this point you can decide whether a touch-up is needed.

Sample Stay Plan (6 nights, 7 days)

We generally recommend a stay of 5–7 days. The plan is to spend the peak swelling period in Korea and fly home after a progress check.

• Day 1
  Arrive → in-person consultation and design. Rest at accommodation near the clinic
• Day 2
  Fat grafting procedure → cold compresses and rest at accommodation
• Days 3–4
  Peak swelling. Rest mostly at your accommodation and share swelling photos with your manager
• Days 5–6
  Light outings with a mask are possible. Progress check and harvest site dressing at the clinic
• Day 7
  Fly home. We explain aftercare and how to contact us after you return

When Flying

• Flying after a progress check is fine for most people, but cabin pressure changes may make the swelling feel slightly worse for a while.
• Drink water often on the plane and avoid alcohol. Be careful not to press on your face with a sleep mask or neck pillow.
• If you wear a compression garment on the harvest site, move your legs often during a long flight.

Before and After the Procedure — Including the Harvest Site

Before

• From 1–2 weeks before, cut back on medicines and supplements that make you bruise easily, such as aspirin, anti-inflammatory painkillers, omega-3 and vitamin E (do not stop prescription medicine on your own; tell us at your consultation).
• Smoking works against fat survival, so we recommend stopping for at least 2 weeks before and after.
• Avoid crash dieting, and bring a record of any previous filler, fat grafting or thread procedures (area, timing, product).

Face care

• Do not press or massage the treated area. Avoid facial massage and meridian treatments for at least 1 month.
• For about 2 weeks, avoid saunas, jjimjilbang, hot baths and heat-based treatments.
• Avoid alcohol and intense exercise for at least 1–2 weeks.
• For a few days, sleep on your back with your head slightly raised, and do not sleep face down.
• In strong sun outdoors, protect bruised areas with a hat and sunscreen.

Harvest site care

• The harvest site can have bruising and tightness for 1–2 weeks, and you may wear a compression garment as the clinic instructs.
• Do not soak the small openings in water for long until the date you are told, and follow disinfection instructions.
• If stitches are used, they are usually removed around day 5–7, or dissolving stitches are used. Please check before you leave Korea.

Normal Reactions and Symptoms to Report Right Away

Common passing reactions

• Swelling, bruising and tightness in the face and harvest site (most improve within 1–2 weeks)
• Volume that looks too full early on, and a slightly firm feel when touched
• Temporary asymmetry from uneven swelling on the two sides

Side Effects to Know About

Contact us immediately if

• The treated area or surrounding skin turns pale white or becomes mottled purple
• Your vision blurs, or you have eye pain, headache or dizziness
• Pain or swelling gets worse day by day, or you notice heat or pus

Questions to Ask at Your Consultation

1. Which areas of my face suit fat grafting, and which are better with filler?
2. Roughly how much will be placed in each area, and where will the fat be harvested?
3. How much absorption do you expect, and how likely is a second session?
4. When and under what conditions is the touch-up done?
5. What kind of anesthesia is used, and does the doctor I consult also do the harvest and injection personally?
6. How do you correct overcorrection or lumpiness if it happens?
7. How do you handle emergencies such as vascular complications?
8. Given my schedule, on which day should I have my progress check before flying home?
9. If a problem comes up after I return home, can I consult with photos?

How to Choose a Clinic

• Whether a board-certified plastic surgeon personally consults and also does the harvest and injection
• Whether they honestly explain absorption and the chance of a second session (rather than stressing only “permanent” or “guaranteed ○○% survival”)
• Whether they explain area by area whether fat suits you or filler or another method is better
• Whether they avoid recommending an excessive amount from the start and look at the balance of the whole face
• Whether they explain anesthesia management and emergency response for sleep anesthesia
• Whether they offer foreign-language support and review your progress by photo after you return home
