Hand Fat Grafting with PRP in Seoul

What is hand fat grafting?

Hand fat grafting restores volume to the backs of the hands using your own fat. With age, the thin layer of fat on the back of the hand diminishes and the skin loses thickness and elasticity. Veins, tendons and knuckle bones become more prominent, and the skin can look translucent or crepey. These changes, described on aging hands, can make the hands look older than the face.

At Will Be, hand fat grafting uses the same principles as PRP micro fat grafting for the face: gentle harvesting, careful purification, and placement of small amounts of fat mixed with platelet-rich plasma.

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

Hand fat grafting may suit you if you:

• are bothered by visible veins, tendons or bony knuckles on the backs of your hands;
• prefer your own tissue to synthetic fillers;
• are in good general health with stable weight;
• can rest your hands from strenuous use for about two weeks.

It may not be the right choice if your main concern is pigmentation or sun spots, which are skin-surface issues better treated with skin therapies; if you have active hand conditions such as inflammatory arthritis flares, poor circulation or recent hand surgery; or if your work involves heavy manual use of the hands that cannot be paused.

How Dr. Kim plans hand rejuvenation

At Will Be, Dr. Kim Jun-young personally performs the consultation, design, procedure and every follow-up. He examines your hands at rest and in different positions, notes asymmetries between the two hands, and assesses skin thickness and how prominent the veins and tendons are.

The goal is soft, natural cover over the underlying structures, not a puffy or overfilled hand. Veins and tendons should still be faintly visible, as they are in young hands; the aim is to soften their prominence rather than hide them entirely. Volumes are therefore planned conservatively and evenly across the back of the hand, stopping short of the knuckles and wrist creases where fat can look lumpy.

The anatomy and the technique

The back of the hand has a simple but delicate structure. Beneath thin skin lie several distinct layers of loose connective tissue, sometimes called the dorsal fascial laminae. The veins run in a superficial layer and the extensor tendons lie deeper. The ideal plane for fat is a smooth, even layer just beneath the skin and above the veins and tendons, where it can spread naturally and cushion the structures below.

Fat is harvested with a fine cannula under low suction, purified to remove blood, oil and fluid, and mixed with PRP prepared from your own blood. It is then introduced through one or two tiny entry points near the wrist using blunt cannulas, which slide between tissue layers and are less likely to injure veins. Small amounts are placed in a fan pattern, then gently molded so the fat spreads evenly across the back of the hand.

Why PRP is used in fat grafting

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 hand 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. Remove rings before the day; hands swell after treatment, and rings should stay off until the swelling settles.

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

Hand fat grafting usually takes about one hour, depending on whether it is combined with facial grafting. It is typically performed under local anesthesia, with light sedation if you prefer. You go home the same day with light dressings.

How long does recovery take?

• Days 1–3: the hands are swollen and may feel stiff; keep them raised on pillows.
• Days 3–7: swelling eases; gentle everyday use is usually fine.
• Weeks 1–2: most swelling resolves; avoid heavy lifting, gripping sports and hot baths.
• Months 1–3: some grafted fat is reabsorbed and the result settles into its long-term form.

The fat grafting recovery guide gives practical aftercare advice.

Risks and how they are minimised

Risks include swelling, bruising, lumpiness, uneven results between the hands, temporary stiffness, infection, oil cysts, donor-site discomfort and variable fat survival. Rarely, injury to veins, nerves or tendons can occur.

Dr. Kim reduces these risks by using blunt cannulas, working in the correct superficial plane, placing small amounts evenly, molding carefully, and advising a period of relative rest so the fat is not displaced while it establishes a blood supply.

How long do results last?

Fat that survives the first few months becomes long-lasting living tissue. The skin itself continues to age and the fat changes with body weight, so results evolve over time. Some patients choose a second, smaller session to refine the result. The alternative is filler, which is quicker but temporary; filler vs fat grafting explains the difference.

What results look like

In the first days the hands look full and slightly puffy, which is expected because a small overcorrection allows for fat that will not survive, and because swelling adds volume. Over the following weeks the backs of the hands settle into a smoother, softer contour. Veins and tendons remain faintly visible but no longer dominate, and the skin often looks less translucent because it has a cushion beneath it. Most patients see the settled result at around three months. Because each hand is treated to its own needs, small differences in the starting point are taken into account so both hands look balanced.

Combinations to consider

Hand fat grafting is often done at the same time as facial fat grafting, using a single harvest. Skin treatments can later improve pigmentation and texture, which fat alone does not change.

Staying in Korea as an international patient

For this procedure, most international patients plan to stay in Seoul for about 5 to 7 days. This usually allows the first wave of hand swelling to settle and a check before travel. 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.
