I asked three different Dermatology clinics in Seoul before finally understanding it: what exactly is so special about Asce+ Exosomes, and why does using them result in skin that looks even better than that treated with Rejuran?

To be honest, when I first saw the term “Asce+ Exosomes”, I thought it referred to some ingredient in a skincare product. It wasn’t until I visited a Dermatology clinic in Gangnam that a doctor explained it to me with a diagram, and then I realized that this concept was completely different from things like hyaluronic acid injections or Rejuran.

After that consultation, I visited two more clinics in a row. It took me nearly a month in total to truly understand what Asce+ Exosomes were all about. Now, in 2026, it has gone from being an “emerging treatment” to a standard topic in Seoul’s Dermatology clinics – almost every clinic is promoting it. However, many people still have only a superficial understanding and are not sure whether this treatment is right for them, what the effects will be, or how much it will cost. What I want to share in this article are all the things you should know before visiting a Dermatology clinic.

How did the craze for Asce+ Exosomes in Dermatology in Seoul emerge? Why did it suddenly become a prominent field of research in 2026?

Asce+ Exosomes are not some entirely new invention. They are actually a concept in cellular biology: tiny vesicles used by cells to communicate and transmit information between each other. These vesicles measure only a few dozen to several hundred nanometers in size and contain various active substances such as growth factors, proteins, and nucleic acids.

It was not until the early 2020s that Asce+ Exosomes truly came into the focus of the Dermatology community in South Korea. Initially, some research institutions and top-tier dermatology clinics began using Asce+ Exosomes derived from stem cell culture media for experimental injections and found remarkable results in treating inflamed skin, aiding in recovery after laser treatments, and Lifting the overall quality of the skin. Coupled with South Korea’s substantial investment in “regenerative medicine,” Asce+ Exosome technology spread rapidly across dermatology clinics throughout the region between 2025 and 2026.

The most popular Asce+ Exosomes products currently on the market are developed by a South Korean company and have undergone multiple clinical trials. These are stem cell-derived Asce+ Exosomes preparations, and they are also the most commonly used brands in Dermatology clinics in Seoul. In addition, imported Asce+ Exosomes such as Exoage and BENEV Exosome are also being used in some clinics.

Asce+ Exosomes vs Rejuran vs Hyaluronic Acid injections: A comparison of differences based on my consultations with three clinics

This is what confuses many people the most, because on first glance, all three seem to be substances that are injected into the skin. However, in reality, their mechanisms of action are completely different. I have compiled the explanations provided by doctors from these three clinics:

Treatment regimen	Core ingredients	Primary function	Effect maintenance	Costs in Seoul (approximate)
Asce+ Exosomes	Mesenchymal stem cell-derived microvesicles + growth factors	Cellular regeneration at the tissue level, reduction of inflammation, and promotion of collagen production	6 months to 1 year	₩220,000 to 500,000 per treatment
Rejuran	Salmon DNA (PDRN/PN)	Stimulates fibroblast cells and replenishes collagen precursors	3 to 6 months	₩220,000 to ₩350,000 per session
Hydrofiller injections (Filler)	Low molecular weight Filler	Quick hydration for immediate glow	1 to 3 months	₩70,000 to 200,000 per session

In simple terms: Hyaluronic acid injections provide “immediate hydration,” Rejuran helps “repair the underlying layers of the skin,” while Asce+ Exosomes enable “cells to learn how to repair themselves again.” These three treatments are not mutually exclusive but rather complement each other. However, if you are on a limited budget and can only choose one, dermatologists in Gangnam generally recommend that people with poor skin quality, weakened skin barriers, or dark spots caused by inflammation try Asce+ Exosomes first; those who need rapid hydration and brightness should start with hyaluronic acid injections.

Comparison of Asce+ Exosomes treatment costs in Seoul in 2026: Gangnam vs Hongdae vs Myeongdong – where is the most cost-effective option?

The cost differences are actually greater than I expected. Based on the quotes from three clinics I consulted, as well as the data compiled by the South Korean medical information platform Modoodoc in March 2026, the distribution is roughly as follows:

• Gangnam District (Cheongdam-dong / Apgujeong): Single treatment costs between ₩350,000 and ₩500,000; 3-treatment package costs between ₩900,000 and ₩1,300,000.
• In the area around Hongdae/Hakgyong: The cost for a single treatment ranges from ₩250,000 to ₩380,000, while a package of 3 treatments costs between ₩650,000 and ₩950,000.
• In the areas around Myeongdong and Dongdaemun: The cost for a single treatment ranges from 220,000 to 350,000 won, while a package of 3 treatments costs between 600,000 and 850,000 won.

Converted into Hong Kong dollars, the cost is approximately HK$135 to HK$385 per session (based on the exchange rate of April 2026, where ₩10,000 is approximately equal to HK$55). In Taiwan, the cost is around NT$500 to NT$1,400 per session. Overall, these prices are about 30% to 50% lower than those at clinics in Taiwan or Hong Kong. This price difference still exists even after South Korea abolished tax rebates for medical beauty treatments in 2026, so taking a flight to receive these treatments is still worthwhile.

However, it is important to note that a low price does not necessarily mean that the treatment is worth undergoing. Some chain Dermatology clinics may offer Asce+ Exosomes at reduced dosages (in terms of centum core), or the brand used may not be ASCE, which is a product backed by clinical data. When consulting, make sure to ask clearly: “Which brand of Asce+ Exosomes will be used this time? What is the dosage in centum core? Will it be administered using the MTS method or a syringe?”

My personal experience with Seoul Asce+ Exosomes: A detailed record of my skin’s changes from the initial consultation to three weeks later

In the end, we chose a Dermatology clinic with a good reputation at Hongdae. The director of the clinic provided services in Chinese, explained everything clearly during the consultation, and did not try to push any products on us. We were assured that the ASCE+ brand would be used, and the treatment would involve 5 centum core injections across the entire face, with a single treatment costing ₩320,000 – which is considered a mid-to-high-end price at Hongdae.

The procedure on the day of treatment generally involves applying an anesthetic for about 30 minutes, followed by the use of a Hycoox device to evenly inject Asce+ Exosomes throughout the face. The entire process takes approximately 20–25 minutes. The discomfort is less intense than that experienced with traditional Filler injections, but the face will have more injection marks afterward. After the treatment, the skin may become slightly red; it is not advisable to wear makeup on the same day, and it is important to enhance moisturization and sun protection measures.

• On the day of the procedure: The cheeks were slightly red, and the skin felt a bit tight to the touch.
• Day 3: The swelling has subsided, and the skin feels “calmer” than usual; the sensitivity that used to exist has decreased.
• On the 7th day: The Pores appeared visibly narrower, and the skin as a whole was no longer so dry and tight.
• Day 14: A friend asked me if I had changed my skincare products recently, saying that my skin looked much brighter.
• On the 21st day: This was the time when I noticed the most significant results. The overall skin tone became more even, the dullness decreased, and the texture of the skin became much smoother.

The effects vary from person to person. Those with more damaged skin barriers or sensitive skin usually experience more noticeable results, while those who already have healthy skin tend to see less improvement.

Who is the most suitable candidate for Asce+ Exosomes treatment in South Korea? Here are three criteria provided by a Dermatology specialist.

After consulting three different clinics, I summarized the situations in which doctors most frequently recommend Asce+ Exosomes treatment.

• Recovery after laser treatments: After procedures such as Pico or Fraxel laser treatments, the skin is in a sensitive recovery phase. Asce+ Exosomes can significantly reduce the recovery time and minimize post-treatment darkening of the skin.
• Sensitive skin/damaged barrier: For those whose skin becomes sensitive and prone to redness due to excessive cleansing or long-term use of irritating skincare products, the anti-inflammatory properties of Asce+ Exosomes are particularly suitable.
• Overall skin quality management: The goal is not to achieve dramatic changes, but rather to improve the underlying condition of the skin and enhance the activity of Collagen. This approach is suitable for people over 30 years old who wish to engage in long-term skin quality management.

Relatively speaking, if your main goal is to achieve “immediate hydration and glow” or to “rapidly reduce eye bags and Tear trough correction”, Asce+ Exosomes may not be the best option. It is also important to note that most Asce+ Exosomes available on the market are registered with the South Korea Food and Drug Safety Agency as cosmetics, rather than drugs. It is crucial to choose a clinic that uses products from well-known brands and provides inspection reports.

Key points for post-Asce+ Exosomes treatment care, and in what situations it is recommended to combine this treatment with other South Korea-based cosmetic procedures

The post-treatment care directly determines whether the results can be optimized to their fullest potential. Below are the key points regarding post-treatment care that I learned from doctors:

• First 3 days: Avoid drinking alcohol, intense exercise, or saunas, as these activities can stimulate blood circulation in the skin and affect the targeted delivery of Asce+ Exosomes.
• Sun protection: After the Asce+ Exosomes treatment, the skin becomes more sensitive, so it is essential to apply a sufficient amount of sunscreen every day. We recommend SPF50+ PA++++ sunscreen.
• Moisturization: Hyaluronic acid cream combined with repair essence forms an ideal post-treatment combination. It is recommended to choose products suitable for sensitive skin that are free from fragrance and alcohol.
• Cleaning: On the day of the procedure, it is not allowed to wash your face or apply makeup; from the next day onwards, you can clean your face as usual, but be gentle in your movements.

In Seoul, many Dermatology clinics recommend the combination of “Asce+ Exosomes + Pico” – first using Pico to remove freckles and smooth the skin, and then applying Asce+ Exosomes to accelerate the recovery process; or the combination of “Asce+ Exosomes + Thermage/HIFU” to tighten the skin and improve its quality at the cellular level. These two combinations have become very common in Gangnam by 2026, and packages are usually available at discounted prices.

If I plan to undergo Asce+ Exosomes treatment in Seoul in 2026, I hope someone will remind me of these 5 things before I set off.

• Confirming the brand is more important than checking the price. Brands with clinical evidence, such as ASCE+ and Exoage, offer more stable results than those labeled as “Asce+ Exosomes produced by a certain Dermatology clinic”. It is advisable to ask about the brand name directly during consultations.
• The best results are achieved with three treatments in a row: While a single treatment does show some improvement, it is recommended to undergo three treatments spaced 2 to 3 weeks apart, as this will help maintain the effects for over a year.
• It doesn’t become brighter the day after the procedure: The best results usually appear around the 3rd week. Don’t assume it’s useless just because you don’t notice any changes in the first week.
• Inform the clinic about your medical history: People with atopic dermatitis or rosacea should proactively disclose this information before the procedure; the doctor will then adjust the concentration and method of the treatment accordingly.
• It remains cost-effective even after the tax rebate is cancelled: Although the tax rebate for medical beauty treatments in South Korea was discontinued in 2026, the costs are still 30% to 50% lower compared to Taiwan and Hong Kong. Overall, it is still worthwhile to make the trip.

If you plan to have Asce+ Exosomes treatment in Seoul during your trip, it is recommended to make an appointment in advance through BeautsGO. The platform supports Traditional Chinese and allows you to easily search for Dermatology clinics that offer this treatment, thus resolving any language barriers that may arise.

FAQ: The 5 most frequently asked questions about Seoul Asce+ Exosomes therapy

Q1: Can Asce+ Exosomes be administered on the same day as hyaluronic acid injections?

Most Dermatology clinics recommend an interval of 1 to 2 weeks between the two treatments, as both are injectable procedures that require some time for the skin to recover. If time is really tight, some clinics may arrange to perform the Asce+ Exosomes treatment followed by the hyaluronic acid injection on the same day, but it is essential to consult with a doctor first to confirm this is feasible.

Q2: How soon after the Asce+ Exosomes treatment can I apply makeup?

No makeup should be applied within 24 hours after the procedure. The next day, light makeup is allowed, but it is recommended to avoid heavy products such as foundation and concealer to allow the skin to breathe freely for a few days.

Q3: Do Asce+ Exosomes have any side effects?

Common temporary side effects include mild redness and needle marks, which usually subside within 2 to 3 days. In a few cases, individuals with sensitive skin may experience mild itching 1 to 2 days after the procedure, but this is considered normal. Severe allergic reactions are extremely rare; choosing a clinic that uses brands with clinical proven safety records can significantly reduce the risk of such incidents.

Q4: At what age is it appropriate to start using Asce+ Exosomes?

Theoretically, anyone over the age of 20 can undergo this treatment, but the most noticeable results are usually seen in people aged 30 to 45 – at this stage, the skin begins to experience collagen loss and its condition deteriorates, making the regenerative effects of Asce+ Exosomes particularly evident. Those in their early 20s who suffer from sensitive skin or need recovery after laser treatments are also ideal candidates for this procedure.

Q5: Can foreigners also easily make appointments for Asce+ Exosomes treatments in Seoul?

Certainly. Nowadays, an increasing number of Dermatology clinics in Seoul offer services in English or Chinese. Some of these clinics also cooperate with BeautsGO, allowing patients to make appointments and arrange Chinese-language interpretation through the platform, so there is no need to worry about language barriers. It is recommended to book at least 3 to 5 days in advance, as popular appointment times tend to fill up quickly.
