MIRACELL Stem Cell Treatment in Seoul

What is MIRACELL stem cell treatment?

MIRACELL is a Korean system for concentrating cells and growth factors from a patient's own blood. At Will Be it is used for an autologous treatment, which means everything injected comes from your own body: no donor cells and no animal-derived ingredients.

The treatment combines three components from your blood: a concentrated cell fraction that includes CD34+ stem and progenitor cells, highly concentrated platelet-rich plasma (PRP), and the growth factors that platelets release. It does not add volume and does not lift. It aims to support the skin's own repair processes from within.

Who is MIRACELL suitable for?

MIRACELL may suit you if you:

• notice dull, tired-looking skin, fine lines or loss of firmness;
• want to support skin quality or recovery after a surgical procedure;
• prefer a treatment based on your own blood rather than a manufactured product;
• understand that results are gradual and vary.

It is not suitable if you have a blood disorder, an active infection, active or recent cancer, very low platelet counts, or are pregnant or breastfeeding. Blood-thinning medicines may need to be reviewed. Dr. Kim checks your medical history and may request blood tests before treatment.

How Dr. Kim approaches MIRACELL

Dr. Kim treats MIRACELL as one tool among several, not as a cure-all. At consultation he looks at what is actually driving your concern: skin quality, volume loss, sagging or a combination. If volume loss or sagging is the main issue, he will say so, because a skin-quality treatment will not fix those.

When MIRACELL is appropriate, he plans the injection areas and depth for your skin, and explains how it may sit alongside treatments such as Rejuran or PRP micro fat grafting.

How it works: from blood draw to injection

The treatment follows four steps:

1. Blood draw. An IV line is placed and a measured volume of your blood is collected.
2. Processing. The blood is placed in a sterile, single-use MIRACELL kit and centrifuged. This separates the blood into layers so that the cell fraction containing CD34+ cells, the platelet-rich plasma and the growth factors can be harvested in a highly concentrated form.
3. IV infusion. Part of the concentrate is returned into a vein through the IV line.
4. Intradermal injection. The rest is injected into the dermis, the skin layer where collagen is made, in the planned treatment areas.

Growth factors from platelets are known to take part in tissue repair. CD34+ cells are progenitor cells that are involved in forming new small blood vessels. Research on how much these effects improve skin appearance is still developing, which is why Will Be describes results cautiously.

What results can you expect, and how long do they last?

Changes are gradual rather than immediate. Many people describe skin that looks brighter and feels smoother and more hydrated over the following weeks. Some people notice more change than others, and some notice little.

How long any improvement lasts varies with age, skin condition and lifestyle. Dr. Kim will discuss whether a single session or a short course makes sense for you, and whether maintenance is worth considering.

Before your appointment

Drink plenty of water the day before and eat normally before treatment, as this makes the blood draw easier. Avoid alcohol for a day or two beforehand.

Tell Dr. Kim about any blood-thinning medicines and supplements, such as aspirin or fish oil; some may need to be paused, as explained in the guide to medications and supplements to pause. Avoid strong skin treatments to the area in the week before.

What happens during treatment and afterward?

After a consultation and skin assessment, numbing cream is applied to the injection areas. The blood draw and processing take place while you rest, followed by the IV infusion and the skin injections. The whole visit usually takes a couple of hours.

Afterwards, small bumps, redness and pinpoint marks at the injection sites are common for a day or two, and bruising can occur, including at the IV site. Most people return to normal activities the same or next day. Avoid saunas, intense exercise and alcohol for about 24 to 48 hours.

Risks and how they are minimised

Because MIRACELL uses your own blood, allergic reactions to the material itself are unlikely. The main risks are:

• bruising, swelling and tenderness at the injection and IV sites, which settle within days;
• infection, which is rare and is reduced by using a sterile, single-use kit and careful skin preparation;
• light-headedness during or after the blood draw, reduced by eating beforehand and resting afterwards;
• uneven results between areas.

Dr. Kim performs the injections himself, and the safety standards page explains how treatments are monitored at Will Be.

What MIRACELL is not

It is important to be clear about what this treatment does not do. MIRACELL is not a facelift and does not lift sagging tissue. It does not replace lost volume the way filler or fat grafting can. It is not a treatment for disease, and it should not be described as one.

The SMART M-CELL system received US FDA 510(k) clearance in 2026 as a concentration system for blood and bone marrow. That clearance relates to the device itself and is not a claim about specific skin results.

MIRACELL, Rejuran or Juvelook?

All three are aimed at skin quality, but they work differently. MIRACELL uses concentrated cells, PRP and growth factors from your own blood. Rejuran uses polynucleotides to support skin repair. Juvelook is a collagen stimulator that builds subtle firmness over time.

The Rejuran vs Juvelook comparison explains those two in detail. Dr. Kim will recommend one, a combination, or none, depending on your skin.

Treatment during a visit to Korea

MIRACELL can usually be done in a single visit, with little downtime, so it fits easily into a short trip to Seoul. Plan for at least 1 to 2 days in Seoul for consultation and treatment, and avoid flying on the same day if you can, so that any early swelling or bruising can settle.

If you are also having surgery at Will Be, Dr. Kim will advise whether and when MIRACELL fits into your plan. The page on how long to stay in Korea helps with planning.
