Apgujeong Stem Cell: This is how you should get it for wrinkle and elasticity results (feat: 5 differences from fillers)

“Doctor, I'm a bit scared of fillers now. I saw a friend who got them and ended up with an uneven texture. But I heard that the stem cell filler made from my own blood, available in Apgujeong, is really natural? Please honestly tell me how it's different from regular filler.”

✅ Conclusion first

Fillers provide immediate volume with an external substance, but they are absorbed and disappear within 6 months to 1 year. Autologous blood stem cell regeneration, on the other hand, directly stimulates collagen production in the dermis using your own growth factors, leading to an increase in overall skin density over 8 to 12 weeks post-treatment. If you're finding limitations with repeated filler treatments, it's important to first understand this structural difference.

Hello. This is Kim Young-gyun, CEO and Director of Core Dermatology.

Lately, in my clinic, I've been asked “Are there any other options besides fillers?” very often. However, most of the articles about stem cell treatments in Apgujeong posted online are missing one crucial piece of information. They heavily advertise the effects, but there are almost no articles explaining why some people get good results while others don't feel much of a difference. If you read this article to the end, you will be able to immediately determine if a dermatology clinic is properly conducting Apgujeong stem cell treatments just by asking one question, no matter which clinic you visit. Today, I will summarize Apgujeong stem cell autologous blood regeneration therapy into five points.

What's the difference between stem cell regeneration treatments in Apgujeong and fillers/skin boosters?

To be honest, even though they look similar on the outside, what happens under the skin is completely different.

When you get a filler injection, an external substance called hyaluronic acid immediately fills in sunken areas. Your cheeks will plump right up, and wrinkles will visibly smooth out. It's fast and effective.

But this is where it ends.

Fillers are meant to fill in empty spaces, not to change the skin itself. After 6 months to a year, the body slowly absorbs them, and the skin returns to its pre-treatment state. It's like pouring water into a leaky pitcher.

Autologous stem cell regenerative therapy goes in a different direction.

When highly concentrated growth factors drawn from your own blood are introduced into the dermis — essentially the deep structure that forms the "bones" of your skin — fibroblasts, which live there, are awakened from their slumber. These cells then begin to actively create new collagen and elastin, the fibers that keep skin taut and elastic proteins that act as the skin's internal springs. Reference: PMC – Regenerative and Stem Cell-based Techniques

So that's where the difference lies.

Fillers look their best the moment they are injected and diminish over time. In contrast, the stem cell regeneration treatment in Apgujeong is not immediately noticeable, but skin density increases over 8-12 weeks as if your own skin is filling in. Clinical studies have also reported a measurable increase in Type I collagen density after 3-6 treatment sessions. Reference: Enyaan Clinic – Stem Cell Skin Regeneration

To give you an analogy, fillers are like applying spackle to a cracked wall, whereas Apgujeong stem cell regenerative therapy is more like replastering the entire wall.

[Director Kim Young-kyun's Comment]
Among middle-aged women in their 40s, there are quite a few who say, “I've been getting fillers for 5 years, but no matter how much I get, they keep sinking.” When I counsel them, I always tell them this: “Filler treatments aren't bad. However, if the foundation of the area you're trying to fill is collapsing, no matter how much you fill it, it's bound to sink again.” You can understand Apgujeong stem cell regeneration as a treatment that raises the density of that foundation, the dermis.

📝 One-line summary: Fillers are ‘instantly filling with external substances,’ while Apgujeong stem cell regenerative therapy is ‘making your own cells create collagen to fill you up from within.".

How to extract stem cells from your own blood — A 3-step process

To get straight to the point, it's a process where a small amount of blood is drawn from your arm, the regenerative components within are selectively concentrated, and then directly injected into your skin.

There's one thing here that many people misunderstand.

“Isn't Apgujeong stem cell treatment about culturing and injecting living stem cells?”

No. To be precise, in autologous stem cell regeneration therapy, the key delivered to the skin is not the ‘cell itself‘ but rather the 'growth factors and regenerative signaling molecules secreted by the cells.' Blood contains regenerative engines like platelet-derived growth factor (PDGF), fibroblast growth factor (FGF), and vascular endothelial growth factor (VEGF). The success of the procedure depends on how highly concentrated these can be extracted without destroying them. Reference: PMC – PRP, Collagen Peptides, and Stem Cells

Core Dermatology uses NOVASTEM technology.

Step 1 — Blood Draw

A small amount of blood is drawn from your arm, just like with a general health checkup. It's less than you might think. The blood draw itself takes less than 5 minutes.

Step 2 — High Concentration Separation

This is the really crucial part. The collected blood is placed in a centrifuge to separate the red blood cells, white blood cells, plasma, and growth factor layers. At this stage, Novastem's technology reduces the destruction of active components compared to conventional centrifugation methods, extracting growth factors at a higher concentration. PRP (Platelet-Rich Plasma) contains platelets concentrated approximately 3 to 7 times higher than normal plasma and holds over 800 types of proteins. Reference: PMC – PRP, Collagen Peptides, and Stem Cells

Step 3: Direct Injection into the Dermis

Concentrated growth factors are delivered directly to the dermis of the skin. At this time, the injection depth, amount, and interval must be adjusted in 0.1mm increments for stable cell engraftment.

By undergoing these three steps, the injected growth factors awaken fibroblasts in the dermis, simultaneously promoting the creation of new collagen (collagen neogenesis) and the growth of new blood vessels (angiogenesis). Reference: PMC – Regenerative and Stem Cell-based Techniques

One more thing. The Ministry of Food and Drug Safety has separate approval and management standards for medical devices derived from autologous blood (such as PRP extraction kits). If you are considering a procedure, it is advisable to check if the extraction equipment used by the hospital has received approval from the Ministry of Food and Drug Safety. Reference: MFDS Medical Device Information Portal

[Director Kim Young-kyun's Comment]
When patients ask, “Isn't all stem cell harvesting in Apgujeong the same?” I use a coffee analogy. Even with the same beans, the taste is completely different whether it's brewed by hand drip or a vending machine. The process of separating growth factors from blood is similar. The concentration can vary greatly depending on the equipment and protocol, and that concentration difference directly leads to differences in results.

📝 One-line summary: The process consists of 3 steps: blood collection → Novastem high-concentration separation → direct injection into the dermis. The outcome is determined by how the growth factors are extracted in high concentration without degradation during the extraction process.

When does the effect of Apgujeong stem cell injections become noticeable and how long does it last?

If I have to give you just one line, there's almost no visible change right after the procedure, and the real transformation gradually appears after 4 to 8 weeks.

Managing expectations is really important in this part.

When people get fillers, they look in the mirror the moment they get up from the procedure and say, “Wow, I look so different!” But with stem cell regenerative therapy in Apgujeong, it's hard to feel a big change on the same day. So, there are quite a few people who worry, thinking, “Is this not effective?”.

But this is normal.

Because Apgujeong stem cell regeneration doesn't involve foreign substances settling in, your own cells need to start working directly. I'll honestly lay out the timeline for you.

Within 72 hours after the procedure — Regeneration switch ON

The injected growth factors bind to receptors on the surface of dermal fibroblasts. From this point on, signals to synthesize collagen and elastin begin to be activated. There are no visible changes yet. Reference: Enyaan Clinic – Stem Cell Skin Regeneration

4-8 Weeks — The Inner Filling Period

Fibroblasts actively produce collagen and elastin. Around this time, feedback such as “My skin feels firmer” and “My makeup applies better” begins to emerge. Recent clinical studies using autologous extracellular vesicles have observed statistically significant improvements in wrinkle depth, hydration, elasticity, and skin barrier function as early as 5 days after treatment (p < 0.05). Reference: PMC – Autologous Blood-Derived EVs Study

8-12 weeks — reach maximum effect

This is the period when collagen density is highest. Fine wrinkles fade, cheek volume naturally increases, and skin texture and tone are refined.

So how long does it last?.

To be honest, one session isn't a treatment that lasts a lifetime. Most specialized clinics recommend an initial course of 3-6 sessions (spaced 4 weeks apart) as a basic protocol, followed by maintenance sessions every 3-6 months. Since it's your own tissue, it naturally maintains itself without adverse reactions, but aging itself doesn't stop, so regular management is necessary.

[Director Kim Young-kyun's Comment]
I have an analogy I always use with my patients. “Apgujeong stem cell regeneration treatment is like exercise. Your body doesn't change after doing it once, but if you do it consistently, your constitution itself changes.” If you expect dramatic changes after just one treatment, you might be disappointed. However, as you repeat the treatment for the third or fourth time and your skin foundation strengthens, the effects will be faster and last longer than previous treatments. Many people at that point realize, “Ah, so this is what it was like.”.

📝 One-line summary: Regeneration begins within 72 hours → noticeable changes in 4-8 weeks → maximum effect in 8-12 weeks. The basic protocol includes an initial 3-6 sessions + 3-6 months of maintenance sessions thereafter.

How to check a hospital's technological capabilities in improving cell survival rates.

To get straight to the point, “drawing” stem cells well and “seating” them well are completely different techniques, and the latter determines 80%%of the results.

This is important because.

Even if you extract highly concentrated growth factors, if the injected cells don't properly settle in the dermis, the body will simply absorb them. According to research, the survival rate of transplanted cells in autologous fat grafting varies greatly, from 25 to 70%. The difference in this variability is precisely due to the injection technique and how well the environment for cell engraftment is created. Reference: PMC – Regenerative and Stem Cell-based Techniques

Core Dermatology addresses this issue in two ways.

First - Low molecular weight hyaluronic acid hybrid blend

We combine highly concentrated growth factors extracted with NovaStem technology with low-molecular-weight hyaluronic acid. Low-molecular-weight hyaluronic acid has a smaller molecular size than regular hyaluronic acid, allowing for faster penetration into the dermis. It also retains moisture, creating a hydrated environment where cells can settle. In simpler terms, it's like thoroughly moistening the soil (dermis) before planting the seeds (growth factors). A secondary benefit is reduced procedure pain.

Second – Direct surgery by a specialist, 0.1mm precise injection

The most dangerous complication of stem cell procedures in Apgujeong is accidental intravascular injection. To prevent this, accurate understanding of anatomical structures, use of blunt cannulas, low-pressure and small-volume injections, and aspiration confirmation before injection are essential. Reference: PMC – Regenerative and Stem Cell-based Techniques

At Core Dermatology, a board-certified dermatologist with 15 years of experience personally oversees the entire process, from blood draw and separation to injection. The injection depth is set at 0.1mm, and the injection volume and intervals are adjusted differently for each skin area. This is a realm that can only be achieved with a skilled touch and accumulated experience.

So there's one question you should definitely ask in a counseling session.

“Does a specialist handle the entire process from extraction to injection?”

This one question is enough. The equipment does the extraction, but the injection is done by people.

[Director Kim Young-kyun's Comment]
To be honest, many people think that because the equipment for Apgujeong stem cell procedures is expensive, “if the equipment is good, the results will be good too.” I thought the same way at first. But after seeing hundreds of cases where the results varied significantly even among hospitals using the same equipment, I've come to realize something. Ultimately, it's all about how safely the cells are engrafted — the precision of the injection is everything. The equipment is basic, but it's the hands that handle it that create the results.

📝 One-line summary: Creating a cell-adhering environment with low-molecular-weight hyaluronic acid and maximizing survival rates through a doctor's precise 0.1mm injection – these two are the key criteria for choosing a hospital.

What are the precautions before and after the procedure, and what are the side effects?

To be honest, the risk of foreign body reaction is low because autologous blood is used, but ignoring the precautions can halve the effectiveness.

First, I'll be upfront about the side effects.

Swelling (edema) and redness (erythema) after the procedure occur in almost everyone. However, the degree is mild and usually subsides within 24 to 48 hours, to a level where you can return to work the next day. In a large-scale study of 1,261 participants, the incidence of moderate complications (such as edema and contour irregularities) was 4.9%, and no severe complications were reported. Reference: PMC – Regenerative and Stem Cell-based Techniques

It's not a panacea.

Before the procedure — please observe only these instructions

It's best to stop taking medications and supplements that affect blood clotting, such as aspirin and omega-3, two weeks before the procedure, as you may bruise more easily. On the day of the procedure, we recommend coming in after a light meal rather than on an empty stomach.

Post-procedure - 48 hours is the golden time

On the day of the procedure, washing your face and applying makeup will be difficult. You must also avoid drinking alcohol, strenuous exercise, saunas, and jjimjilbangs for 48 hours. During dry periods with heavy fine dust, similar to Korea's transitional seasons, you need to be more diligent than usual with sunscreen and moisturizing to maintain an environment where growth factors can work stably.

This person should make a careful decision.

Individuals with blood disorders, those taking anticoagulants, keloid scar formers, pregnant or breastfeeding women must consult with a specialist before the procedure. We also want to be upfront that long-term safety data for stem cell procedures in Apgujeong is still being accumulated. The academic community has not yet fully established a standard protocol, and ongoing research is being conducted. Reference: PMC – PRP, Collagen Peptides, and Stem Cells

That's why I don't call it a panacea. However, because it uses the patient's own body materials, the rejection rate is low, and when performed precisely, stable results can be expected compared to other regenerative therapies. This is the honest answer based on current evidence.

[Director Kim Young-kyun's Comment]
There are places that sometimes advertise “no side effects,” but I think that's a bit of an irresponsible statement. Any procedure has the possibility of side effects, and I believe what's important is to explain them in advance and prepare for them. During consultations, I first tell people, “This is the limitation of this procedure, and for some individuals, a different method might be better.” I've found that to be the way to actually earn patients' trust.

📝 One-line summary: Downtime is mild redness for 24-48 hours. Avoid alcohol, saunas, and strenuous exercise for 48 hours, and thoroughly apply sunscreen and moisturizer.

If you are considering stem cell skin regeneration treatments in Apgujeong, be sure to confirm these three things directly with the clinic. If the hospital provides clear and specific answers to your questions, the treatment results are likely to be reliable.

At Core Dermatology, Dr. Kim Young-gyun, a board-certified dermatologist with 15 years of experience, personally oversees the entire process, from blood collection and Novastem concentrated separation to the hybrid blending of low-molecular-weight hyaluronic acid and precise 0.1mm injections. “We aim for a customized approach, rather than applying the same protocol to all skin types. We consider factors like dermal thickness, degree of aging, and lifestyle environment.”.

Don't just blindly choose based on reviews and low prices — carefully consider where you're entrusting the foundation of your skin using the criteria I've outlined today.

Thank you for reading the long text.

Sincerely, Kim Young-gyun, Chief Director of Core Dermatology
