PRP Micro Fat Grafting for the Face in Seoul

What is PRP micro fat grafting?

PRP micro fat grafting is a procedure that takes a small amount of fat from one part of your body, usually the abdomen or thighs, purifies it, and injects it in very fine droplets into areas of the face that have become hollow or flat. The fat is combined with platelet-rich plasma (PRP) prepared from your own blood.

PRP micro fat grafting is one of Will Be's recognised strengths. Its appeal is simple: the material is your own, it integrates with the surrounding tissue, and the portion that survives behaves like the rest of your facial fat. It is used to address facial volume loss in the temples, forehead, cheeks, under-eye hollows, nasolabial folds, and around the mouth and chin.

Who is it for, and who is it not for?

Fat grafting may suit you if you:

• have hollow temples, flat cheeks, a sunken under-eye area or deepening folds;
• would prefer your own tissue to synthetic fillers;
• want a result that can be long-lasting, and accept that more than one session may be needed;
• have enough donor fat, which even slim people usually do in small quantities.

It may be less suitable if you want a precise, immediately predictable result in a small area, where filler may be easier to control; if your weight is likely to change significantly; or if you have recently had large volumes of filler in the same area. The page comparing filler vs fat grafting sets out the trade-offs.

How Dr. Kim designs facial fat grafting

At Will Be, Dr. Kim Jun-young personally performs the consultation, the design, the harvest, the grafting and every follow-up. Fat grafting is as much about judgement as technique, and a single surgeon managing each step keeps the plan coherent.

Design starts with light and shadow. Dr. Kim studies where your face has lost its curves, how light falls across the temple, cheek and lower lid, and which hollows make you look tired or older. He also looks at your face from different angles and when you smile, because fat placed in a moving area behaves differently from fat placed over bone. The aim is to restore your own contours rather than to add volume for its own sake. Over-filled cheeks or a heavy midface can look as unnatural as hollowness.

Volumes are planned conservatively for each zone, with a small allowance for the portion of fat that will not survive. Dr. Kim prefers a natural result that can be refined later to an overfilled one that cannot easily be reduced.

The technique and why PRP is used

The procedure has three stages. First, fat is harvested with a fine cannula through a tiny incision, under low suction to protect the fragile fat cells. Second, the fat is processed: blood, oil and fluid are separated so that only healthy fat tissue is used. Third, the purified fat is mixed with PRP and injected with very fine cannulas in tiny amounts, layer by layer.

Transplanted fat has no blood supply of its own at first. For the first few days it survives by absorbing nutrients from surrounding tissue fluid, a process called plasmatic imbibition, until new capillaries grow into it. Fat cells that are too far from a blood supply during this window do not survive; they are gradually reabsorbed or, if clustered, can form small oil cysts or firm nodules.

PRP, or platelet-rich plasma, is prepared from a small sample of your own blood, spun in a centrifuge to concentrate the platelets. Platelets release growth factors, signalling proteins involved in healing and in the formation of new blood vessels. The rationale for mixing PRP with the fat graft is to support this early phase: to encourage new vessels to reach the graft sooner and to support the healing environment around it. Published research is encouraging but not uniform, and PRP should be understood as a supportive measure rather than a promise of higher survival.

The most reliable factors remain technical: gentle harvesting, careful processing, and placing fat in tiny amounts through many passages at different depths, so that every droplet is close to a blood supply. That is the meaning of micro fat grafting.

How to prepare

Preparation for PRP micro fat grafting begins at consultation, where Dr. Kim reviews your health, medications, weight history and any previous fillers or fat grafting. Stop smoking and nicotine products for several weeks before and after; nicotine narrows the small vessels that new fat depends on and is one of the clearest threats to graft survival. Blood thinners, aspirin, some anti-inflammatories, fish oil, vitamin E and certain herbal supplements may need to be paused under medical advice.

Keep your weight stable in the weeks before surgery, since grafted fat behaves like the fat it came from. Arrange a companion for the day, prepare cold packs and loose clothing, and bring records of any fillers placed in the area.

Anesthesia and treatment time

The procedure typically takes about one and a half to two and a half hours, depending on the number of areas treated. It is usually performed under IV sedation with local anesthesia at the donor and treatment sites, with continuous monitoring as described on safety and anesthesia. You go home the same day.

How long does recovery take?

• Days 1–3: swelling is often the most noticeable, especially under the eyes; the donor site may feel bruised.
• Days 5–7: small sutures at entry points, if used, are removed; swelling eases.
• Weeks 1–2: most people are comfortable in public; slight fullness remains.
• Months 1–3: part of the grafted fat is reabsorbed and the result settles. What remains after about three months is generally stable.

Avoid pressure or massage on grafted areas unless advised. The fat grafting recovery guide covers aftercare in detail.

Risks and how they are minimised

Risks include swelling, bruising, asymmetry, lumps or irregularities, oil cysts, under- or over-correction, infection, and donor-site discomfort or contour irregularity. Rarely, fat injected into the face can enter a blood vessel and cause serious complications including skin injury or vision problems. How much fat survives varies from person to person, and a second session is sometimes needed.

Dr. Kim reduces these risks by using blunt, fine cannulas that are less likely to enter vessels, injecting slowly in tiny amounts while moving, knowing the vascular anatomy of high-risk areas such as the glabella and nose, placing conservative volumes, and reviewing you closely afterward.

How long does fat grafting last?

Fat that survives the first few months establishes a blood supply and becomes long-lasting living tissue. It changes with your body: it can enlarge slightly with weight gain and diminish with weight loss, and the face continues to age around it. Many patients find a single session sufficient; others choose a second, smaller session after around three to six months for refinement.

Combinations to consider

Fat grafting pairs naturally with lifting procedures such as a facelift or thread lift, since lifting repositions tissue while fat replaces what has thinned. Under-eye fat grafting is covered separately on under-eye fat grafting.

Staying in Korea as an international patient

For this procedure, most international patients plan to stay in Seoul for about 7 days. This usually allows removal of any small sutures and a check once the early swelling has started to settle. It is generally sensible to fly only after Dr. Kim has examined you in person, so that any small issue can be managed while you are still nearby.

Choose accommodation close to Sinsa so follow-up visits are short and easy, and leave a few genuinely restful days in your plan. The page on how long to stay in Korea helps with planning. Fat grafting in particular continues to evolve for around three months, so much of your progress will happen after you are home. Dr. Kim reviews it through photographs and messages, as explained in follow-up care abroad. Because one surgeon follows you from the first consultation, the person assessing your photographs is the person who placed the fat.

Distance from home can make early swelling feel more worrying than it would locally. Knowing what is expected at each stage, keeping the clinic's KakaoTalk contact at hand, and sending a message whenever something concerns you all make the experience calmer.
