Before flying to Seoul, make sure you understand everything about Rejuran: recovery period, side effects, suitable candidates, and the prices in Gangnam.
I have friends who, after undergoing the Rejuran Healer treatment in South Korea, noticed a significant improvement in the glow of their skin and looked much more energized. This really caught my attention. After doing some in-depth research, I realized that Rejuran is actually quite different from regular hyaluronic acid injections; it’s far more than just a simple “shot.” So, I decided to go to Seoul to experience it firsthand and compile all the information regarding the recovery period, potential side effects, suitable candidates, and costs, so that I could share it with anyone considering this treatment.
What is Rejuran? How is it different from ordinary hyaluronic acid injections?
Rejuran Healer (often simply referred to as “Rejuran”) is a highly popular skin regeneration treatment in South Korea in recent years. Its main ingredient is PN (polynucleotides), which are extracted from fish DNA fragments and have a structure very similar to that of human skin cells. As a result, they are easily absorbed by the skin and pose a high level of safety.
Compared to conventional hyaluronic acid-based fillers such as Restylane and Juvelook, the key difference of Rejuran lies in its ability to promote “renewal” rather than merely providing “hydration”:
- Skin Booster: Primarily composed of Filler, its main function is to provide deep hydration and maintain skin moisture, making it suitable for dry and flaky skin.
- Rejuran: Mainly composed of PN (polynucleotides), its functions include activating the skin’s self-repair mechanism, reducing the size of Pores, fading fine lines, and evening out skin tone.
- Rejuran HB: Based on the classic formula, a small amount of Filler is added to achieve both “renewal” and “moisturization”.
Simply put, if your problems include “dull skin, visible Pores, increased fine lines, and a reduced overall glow,” Rejuran is more targeted in addressing these issues than mere hyaluronic acid injections for moisturization.
How long is the recovery period after Rejuran treatment? I actually recorded it on the day of the surgery.
The recovery period of Rejuran is one of its major advantages. Traditional laser treatments require several days of rest after the procedure, but since Rejuran is an injectable treatment, patients can immediately experience a “instantly hydrated” effect.
On the day of the procedure, mild redness and small bumps (commonly known as “pinholes”) may occur; these symptoms usually subside on their own within 24 to 48 hours. A friend of mine who had the treatment said that she went back to work the day after, despite the slight bumps, which were completely unnoticed by others.
Postoperative care is actually quite simple:
- Do not apply makeup within 24 hours after the procedure to allow the needle holes to heal naturally.
- Strengthen sun protection; it is recommended to use sunscreen products with an SPF of 50 or higher and a PA+++ rating.
- Avoid using skincare products containing acids or exfoliants within one week after the procedure.
- To enhance moisturization, you can use non-irritating moisturizing face masks.
What are the side effects of Rejuran? Things you must know before getting it injected.
According to clinical data, the side effects of Rejuran are generally mild and short-lived.
Normal reactions that most people experience after the procedure (usually disappearing within 2–3 days):
- Mild flushing or swelling
- Small bumps (resembling small papules caused by mosquito bites, which disappear within 2–3 days)
- After the procedure, there may be a slight stinging or burning sensation at the treated area, which usually subsides within 1 to 2 hours.
It is particularly important to note that in the following situations, it is recommended to have thorough discussions with your doctor before the procedure:
- For those who are allergic to fish protein (since Rejuran contains fish DNA)
- Pregnant women and lactating women (it is recommended to postpone the injection)
- The skin is currently inflamed or infected; it must be treated before the procedure can be performed.
- People who are taking anticoagulants (must discontinue these medications before undergoing the procedure)
Who is Rejuran suitable for? And who is not recommended to use it?
Rejuran is not a panacea, and it is not suitable for everyone. Here are some points to help you quickly determine whether you are the right candidate for Rejuran:
- Highly suitable for: people with enlarged Pores, fine lines, uneven skin tone, those who want to enhance the glow of their skin, and young adults aged 25–45.
- It shows certain effects: it helps with mild acne scars, reduces postoperative redness, and alleviates skin dryness and peeling.
- Not very suitable for: deep wrinkles (which require fillers or HIFU), severe skin laxity (which requires thread lifting or facelift surgery), or those currently undergoing other invasive skin treatments.
It is recommended that if you are getting injections for the first time, start with 1–2 injections to see how your skin reacts, and then decide on the subsequent frequency of injections.
What is the price of Rejuran in South Korea? A review of the market situation in Gangnam, Seoul, in 2026.
In South Korea, the cost of Rejuran treatments is significantly lower than in Taiwan and Hong Kong, which is one of the main reasons why many people travel specifically to Seoul for such procedures. Below are some reference prices for major Dermatology clinics in Gangnam for the year 2026:
| Rejuran types | Gangnam, South Korea ₩ | Taiwan NT$ | Hong Kong, HKD |
|---|---|---|---|
| Rejuran Classic Edition (Rejuran Healer) | ₩150,000 – ⩽₩250,000 per session | NT$8,000 – NT$15,000 per session | HK$3,500 – HK$7,000 per session |
| Rejuran HB (Regeneration + Hydration) | ₩200,000 – ⩽₩350,000 per session | NT$12,000 – NT$20,000 per session | HK$5,000–HK$9,000 per session |
| Rejuran for the eyes | ₩100,000 – ⩽₩180,000 per session | NT$6,000–NT$12,000 per session | HK$2,500 – HK$5,500 per session |
| Rejuran Full Face Treatment Package (3 sessions) | ₩400,000 – ⩽₩600,000 | NT$22,000 – NT$40,000 | HK$10,000 – HK$18,000 |
Let’s do a simple calculation: taking the Rejuran Classic version as an example, the cost of a single treatment in Gangnam, South Korea, is approximately 60–70% of the price in Taiwan. Moreover, the Rejuran used in South Korea is directly supplied by the manufacturer, so the quality control is relatively strict. Many friends from Taiwan choose to buy three treatment packages at once, which really results in a high cost-performance ratio.
Prices can vary depending on the clinic, location, and the qualifications of the doctors. Clinics in Gangnam tend to charge slightly more than those in Hongdae, but they generally offer better equipment and facilities. It is recommended that foreigners make reservations through BeautsGO, as they often offer discount packages or free consultation services.
Gangnam Betterme Gangnam: The preferred institution for foreigners seeking Rejuran treatment
Betterme Gangnam is a Dermatology clinic highly popular among foreign tourists in the Gangnam area. The clinic features a modern environment, advanced equipment, and excellent translation services, ensuring smooth communication for patients. It offers a range of treatments such as Rejuran, INMODE body sculpting, HIFU, and Thermage FLX, making it an ideal one-stop destination for foreigners looking to receive cosmetic treatments in Seoul.
Frequently Asked Questions about Rejuran
Q1: How often should Rejuran be administered to be effective?
It is generally recommended to receive the treatment every 4 weeks. After 3–5 consecutive sessions, the skin condition will enter a stable phase of improvement. Thereafter, maintenance treatments every 3–6 months are sufficient, and there is no need for too frequent injections.
Q2: How long does it take to see the effects after using Rejuran?
Everyone experiences it differently, but most people notice that their skin becomes smoother and more radiant after just the first week. True “significant improvements” usually begin to appear after the second or third treatment, as the production of new Collagen takes some time.
Q3: How long does the effect of Rejuran last?
If administered just once, the effects generally last for 1 to 2 months. However, after completing a full course of treatment (3 to 5 sessions), the effects can last for 6 to 12 months, depending on individual physical conditions and post-treatment care.
Q4: Can Rejuran be used in combination with other treatments?
Sure, but the order is very important. It is generally recommended to inject Rejuran first, and wait for 5–7 days until the injection sites have healed before undergoing energy-based treatments such as laser or Thermage. For the specific combination of treatments, it is best to consult your attending physician directly.
Q5: What if foreigners going to South Korea for Rejuran treatments face language barriers?
It is recommended to make reservations through platforms such as BeautsGO. These platforms usually offer customer service in Chinese or English, which can help you communicate directly with the clinics regarding your medication needs. Some clinics also have on-site translators, so you don’t have to worry about language barriers.
Q6: What is the difference between Rejuran and Teosyal/Youth Injection?
Rejuran is a “regenerative” type, focusing on repair and the production of new Collagen; products like Restylane / Juvelook, such as Bbing Needle, are “filler” types, designed to provide immediate volume enhancement. The two can be used in combination, but their mechanisms of action are completely different.
Q7: Can I wear makeup after getting Rejuran injections?
It is recommended not to wear makeup within 24 hours after the procedure; after that, you can apply makeup as usual. It is better to use mild, mineral-based cosmetics.
Q8: At what age is Rejuran suitable for use?
Generally speaking, people aged 20 to 60 can benefit from this treatment, but the effects are most noticeable in those aged 25 to 45 (during the stage of early middle age when the first signs of aging begin to appear). For those in their early 20s who simply want to enhance skin hydration, hyaluronic acid injections may be more suitable.
My honest advice is: Is it really worth flying to Seoul just to get Rejuran?
If you meet any of the following criteria, I would recommend that you seriously consider going to South Korea for Rejuran treatment:
- If you have been troubled by enlarged Pores, fine lines, and dull skin for a long time, using skincare products alone may not be very effective.
- If your budget is limited but you still want to experience the high cost-performance ratio of South Korea’s medical beauty services…
- I already had plans to travel to South Korea and thought I would take the opportunity to get some skin care treatment while I was there.
- I have trust in the equipment and technology used in the medical aesthetics industry in South Korea.
If your skin problems are relatively severe (such as deep wrinkles or significant sagging), it is recommended that you first consult a professional doctor for a comprehensive assessment before deciding whether to use Rejuran. Rejuran is not a panacea, but it is definitely a great choice with “high cost-effectiveness, a short recovery period, and suitability for regular maintenance.”
If it is your first time undergoing this procedure, it is recommended to find a clinic that provides specialized services in Traditional Chinese. This will ensure smoother communication, and any issues that may arise after the surgery can be addressed promptly.
