Six checks that decide a rejuran result
| Check | Why it decides the result | How to verify before paying |
|---|---|---|
| 1. Sealed box with lot number | Genuine Rejuran ships as a sealed syringe in a box carrying a lot number and the maker's authentication mark; a syringe that arrives already open cannot be identified. | Ask for the box to be opened in front of you and photograph the lot label. Compare the mark with the maker's authentication guidance linked in Sources. |
| 2. Product variant and cc in writing | Several products share the name: Healer for the face, I for the under-eye, S for scars and HB with added hyaluronic acid, each in different syringe sizes. A low figure is often a smaller syringe or a different variant. | Ask for the variant name and the exact cc on the quote, and whether a 4cc figure means two sealed 2cc syringes or something else. |
| 3. Hand injection or injector device | A multi-needle injector covers the face quickly and evenly; hand injection by the doctor allows targeting of specific lines but takes longer and is usually priced higher. Clinics do not always say which they use. | Ask which method is used for your area, who performs it, and what the difference in figure covers if both are offered. |
| 4. Numbing plan spelled out | Dozens of shallow injections are uncomfortable without adequate numbing; cream time, and whether cold air or a nerve block is added, change both comfort and the time to allow. | Ask how long numbing cream is applied and what else is used. A clinic that treats this as routine answers in one sentence. |
| 5. Course spacing against your stay | The maker and most clinics describe a course of several sessions a few weeks apart, and package figures often assume that you complete it at the same clinic. | Tell the clinic your dates and ask whether a package can be used over separate trips, what happens to unused sessions, and whether a single-session figure is available. |
| 6. What the printed price leaves out | Figures are commonly shown before 10% VAT, numbing or a post-care laser may be added separately, and event figures carry conditions. | Ask for the total including VAT, numbing and any add-on the clinic treats as standard, plus the conditions on any event figure. Get it in writing. |
Eight questions to send a clinic before booking
Paste these into WhatsApp or email. A clinic that answers in writing is giving you something to hold it to.
1. Which Rejuran product (Healer, I, S or HB) and how many cc does your printed price cover? 2. Will the sealed box be opened in front of me so that I can see the lot number and authentication mark? 3. Is the injection done by hand by a doctor or with an injector device, and who performs it? 4. How long is numbing cream applied, and is cold air or a nerve block used as well? 5. Is the printed price before or after 10% VAT, and does it include numbing and any add-on treatment? 6. I am in Seoul from [date] to [date]; can a package be used over separate trips, and is a single-session price available? 7. Will an English-speaking staff member be present during the consultation and the injection? 8. What should I expect in the first 48 hours, and whom do I contact if bumps or redness do not settle?
Red flags
- A figure with no product variant and no cc, or a syringe already open when you enter the room.
- No box, no lot number, and no answer when you ask about the authentication mark.
- A full-face figure that turns out to cover a smaller syringe once you are on the table.
- A multi-session package pushed before anyone has asked how long you are staying in Korea.
- No written English aftercare for the bump stage and no messaging channel for questions after you leave.
One-doctor clinics in Gangnam for rejuran: what their websites state
Foreigners often ask for a “one-doctor” or “boutique” clinic rather than a large chain. No public source measures results by clinic size, so this table does not label anyone. It records, for each Gangnam clinic that prints a rejuran price, what its own website states: how many doctors it names, how many branches it names, who it says does the consultation, whether it mentions a private room, whether it states the same price for foreigners, and what share of its printed rejuran prices in our store are event prices. Read 12 Nov 2026.

11 of 11 clinic sites read. “None found” means our read found no named doctor, not that there is none; some sites list doctors only in images or scripts. Counts are as of the read date and can change. A clinic naming one doctor and one branch reads as a single-doctor practice; whether that doctor performs your treatment is something to confirm in writing.
Aftercare when you are flying home
Expect a raised bump at each injection point, with redness and some pinpoint bruising, for the first 24 to 48 hours; the bumps flatten over one to three days and are the reason many clinics advise no makeup on the day. Clinics generally advise gentle cleansing, a plain moisturiser and sunscreen, and no sauna, swimming, hard exercise or alcohol for two to three days. Flying is not usually restricted, so a flight the next day is common, although you may still be visibly bumpy at the airport. Before you leave Seoul, save the product variant, cc, lot number, treatment date and the clinic's messaging contact, and ask for written English aftercare and the clinic's advice on when a second session should fall if you continue elsewhere. Bumps or redness that have not settled after a week, increasing swelling, warmth, or any sign of infection should be shown to a doctor where you are, with the product name and lot number in hand. Changes in texture are judged a month or more after the course, so photos sent to the clinic at that point are the useful review, not photos from the first week.
Questions people ask
Which rejuran clinic in Gangnam should you choose?
No public source audits results per clinic in Korea, so no page can honestly name one. 11 Gangnam clinics print a rejuran price and are listed by name on this site; start with the checks on the how-to-choose page, then confirm by message the spec, the product or device, the VAT condition and whether English covers the consultation itself.
Is a one-doctor clinic better than a large chain for rejuran in Gangnam?
No public data compares results by clinic size, so neither is better by default. What differs is who consults and treats you, waiting and scheduling, and price conditions. Of the 11 Gangnam rejuran clinic sites we read, 1 name exactly one doctor and one branch, 3 state that the doctor consults 1:1, and 0 state the same price for foreigners. Use the table above, then ask the clinic in writing who will perform the treatment.
How much does rejuran cost in Gangnam?
As printed on their own websites, 7 Gangnam clinics show a 2 cc rejuran price between ₩135,000 and ₩760,000, read 12 Nov 2026. Most printed prices exclude 10% VAT, and event prices carry conditions such as a first visit. A quote far below ₩135,000 usually means a smaller spec, a different product or an event.
What is the difference between Rejuran Healer, I, S and HB?
Healer is the standard full-face product, I is a lower-concentration product in a smaller syringe for the thin under-eye skin, S is for acne scars and HB combines polynucleotide with hyaluronic acid. Our table prints 2cc and 4cc rows; the variant behind each row is shown where the clinic names it, and you should ask for it where it does not.
What is Rejuran and is it the same as a skin booster?
Rejuran is a polynucleotide gel derived from salmon DNA, cleared in Korea as a medical device and injected shallowly across the skin to support its repair environment. Clinics group it with skin boosters because it is injected in many points for skin quality, but it is a different material from the hyaluronic acid boosters sold under that label.
