Korea Rejuran Recovery Program: What a Rejuran Course Involves
Dr. Jong Seon Kim · Director, Gangnam HERA9 min readLast updated 
On this page
Have a week in Seoul and wondering whether a Korea Rejuran recovery program will leave bumps on your face for the flight home?
Read this before you pick your treatment day.
You'll know what a Rejuran course involves, what decides the cost, which review claims hold up, how the methods differ, and how to place the recovery days around your flights. That should make it easier to judge whether it fits your skin, your budget and this trip.
Hello, I'm Dr. Jong Seon Kim, Director of Gangnam HERA Plastic Surgery Clinic.
At HERA, the specialist who consults with you is the one who performs your treatment, and the sealed vial is opened in front of you. Foreign patients pay the same price as Korean patients, you get a written estimate before treatment, and consultations can run through an English interpreter.
I'm writing this because many visitors book Rejuran for their last afternoon in Seoul, and that's the one slot I'd avoid.
There's no single packaged “recovery program” for Rejuran. What people usually mean is a course of polynucleotide injections, given as a series of sessions a few weeks apart, with small bumps at the injection points that usually settle within a day or two.
If you're not sure your skin or your dates fit, send one daylight photo of your face and your arrival and departure dates on WhatsApp, and ask the one thing you want settled: can a session fit into this trip?

What a Rejuran course is
Rejuran is an injectable made from polynucleotides (PN), purified DNA fragments taken from salmon. On our menu it comes as Rejuran, Rejuran HB and Rejuran I. It goes in as tiny amounts placed just under the skin across the treated area. The aim is to support the skin's own repair. It doesn't fill anything.
A review in Pharmaceutics that compares polynucleotides with the related PDRN describes them as working through tissue-repair and hydration pathways, which fits what people notice on the skin: texture and moisture first. Most studies of polynucleotides in esthetic medicine use a series of sessions rather than a single injection, and that is the real meaning of “program” here. Change builds over weeks, so one session on a short trip is the first step of a course.
For the ingredient itself in more depth, our polynucleotide skin booster guide to Rejuran covers the background.
Who is a Korea Rejuran recovery program right for?
In short, it tends to suit skin that looks tired rather than skin that has lost shape: fine crepey texture, dryness that creams don't fix, dullness, shallow texture irregularities, thin skin under the eyes. These are skin-quality problems, and skin quality is what polynucleotides work on.
It fits less well when the main complaint is volume or sagging. Rejuran doesn't lift a jowl or refill a hollow cheek. If that's what bothers you, the conversation turns to filler, a collagen-stimulating booster such as Juvelook, or a lifting treatment. My aim is only what you truly need, so I'd rather say that at the start than plan a course that can't answer your concern.
Say you're in your mid-50s, your cheeks look crepey in photos, you also feel your lower face has dropped, and you have eight days in Seoul. I'd look at the two concerns separately. Rejuran can work on the texture. The drop is a different problem, and whether to add anything for it that same week is its own decision, made with your flight date in front of us. If texture is what you mind most, one session early in the trip is where I'd start, and the rest of the course is something to plan around a return visit.
Under-eye skin is its own case.
Which Rejuran methods and versions can you choose?
The three versions on our menu differ by formulation and by area. Rejuran is the original formulation, used across the face for texture and hydration. Rejuran I is made for the thin skin around the eyes.
The method is usually the same: many small, shallow injections placed by hand, which is why you see a grid of little raised points straight afterward. How deep and how close together the points are placed affects how visible those bumps are the next morning, and it's one reason the person injecting matters as much as the product.
Around the eyes the skin is thinnest and bruises most readily. If that is your area, what Rejuran can and can't do around the eyes goes into it separately.
What do Rejuran reviews get right and wrong?
Review threads repeat the same few claims. Some hold up medically, some don't.
“The bumps look alarming.” True for the first hours. The raised points are the product sitting in the skin, and for most people they flatten within a day or so, sometimes a little longer around the eyes.
“It stings more than other boosters.” Often true, especially with the original version. That's the reason HB, with lidocaine, exists, and numbing cream helps.
“One session transformed my skin.” This is the claim I'd read most carefully. Polynucleotides work gradually, and the studies use a series of sessions. A glow the next morning is mostly hydration and mild swelling, so judge a course weeks later, in the same light you took your first photo in.
“Anyone can have it.” Not quite. It's made from salmon DNA, so a fish or salmon allergy matters, and the people who should wait are listed in the risk section below.
What decides the cost of your course?
Four things move the figure. The version comes first: Rejuran, Rejuran HB or Rejuran I. Then the area, full face, under-eye only, or both. Then the number of sessions in the course and how many of them happen during this trip. Last, whether you combine it with another treatment on the same visit, for example a filler for a hollow that Rejuran can't address.
Foreign patients pay the same price as Korean patients, and you receive a written estimate before treatment, so the number is on paper before anything is injected. If you'd like to see how those items are laid out, our page on what a Rejuran estimate includes walks through it, and if volume turns out to be part of the plan, how filler costs are set in Korea follows the same logic.
To get the figure for your own case, ask on WhatsApp what a course would cost for your skin, with one photo and the area you want treated.
Why the vial is opened in front of you
Rejuran is a branded product, and you can't tell genuine from counterfeit by looking at your skin afterward. I use only genuine, approved products, and the sealed vial is opened in front of you, so you see the box and the vial yourself. The doctor who consults with you is the one who injects you; it isn't handed off. You can read about the three plastic surgery specialists on the HERA Clinic English homepage.
How do the recovery days fit around your flights?
For most people the visible part of recovery is short. Here is what is usual, and what to plan for.
| When | What's usual | What to plan |
|---|---|---|
| Same day | Raised bumps at the injection points, redness, some tenderness | No makeup on the treated area; keep the evening quiet |
| By day 3 | Bumps usually flattened; pinpoint bruises possible, more often under the eyes | Makeup is usually fine once the skin has settled; skip saunas, hard workouts and heavy drinking for the first couple of days |
| By day 7 | Any bruising usually fading; skin back to normal for daily life | A comfortable point for photos, sightseeing and the flight home |
Before you fly
don't book Rejuran for the day before your flight or the day you leave. Leave at least three days in Seoul after the session, so a bruise or an unexpected reaction shows up while you can still come back in.
The calendar matters too. The clinic is open until 5 pm on Saturdays and closed on Sundays and public holidays, so if you land on a Saturday, Monday or Tuesday works well as a treatment day for an eight-day stay. HERA gives recovery guidance and follow-up in English, which helps once you're home.
When you message, mention your flight home date and the area that matters most to you, and ask which day of your trip to book the session.

Risks and side effects to know
The common reactions are temporary: raised bumps, redness, mild swelling, tenderness and pinpoint bruising. They usually settle within a few days, and bruises under the eyes can take up to a week or so. Less often, a small firm bump lasts longer than expected, and rarely there is an infection or an allergic reaction. How quickly each person settles varies, and whether Rejuran suits you is something I decide only after examining your skin in person.
As a general rule, wait or skip it if you have an active infection, acne flare, cold sore or inflammation in the area; if you've had a laser or peel on the same area recently; if you take isotretinoin now or did recently; if you're pregnant or breastfeeding; or if you're allergic to fish or salmon-derived ingredients, or to lidocaine in the case of HB. Blood thinners and bleeding disorders make bruising more likely, so mention them at the consultation.
If, after you fly home, redness spreads, pain increases rather than fades, the area turns warm or you develop a fever, see a local doctor promptly and send a photo to us on WhatsApp. The U.S. CDC's guidance on medical tourism recommends bringing copies of your treatment records home and planning follow-up care before you travel, and that applies to injectables too.
The treatment itself. If you want the clinical detail — who it suits, how a session runs, recovery and the honest limits — it is set out on our Rejuran page.

One photo is enough to start, and you can ask before booking anything. When you come in, I examine your skin and recommend the course that fits it and your days in Seoul.
FAQ
Frequently asked questions
Q1How many Rejuran sessions are in a course?
Published studies mostly use a series of sessions spaced a few weeks apart rather than a single injection. The number that suits you is set after your skin is examined. On a short trip, many people start with one session and plan the rest around a later visit.Q2Can I fly the day after Rejuran?
Flying isn't usually a medical problem in itself after Rejuran, but I'd avoid booking the session for the day before your flight. Leaving at least three days in Seoul means a bruise or an unexpected reaction shows up while you can still come back to the clinic.Q3Does Rejuran hurt?
It stings, and many people find the original version more uncomfortable than other boosters.Q4When can I wear makeup after Rejuran?
Usually from the next day, once the injection points have closed and the bumps have flattened. On the day itself, keep makeup off the treated area.Q5Is Rejuran the same as a filler?
No. Rejuran is a polynucleotide injectable aimed at skin quality, such as texture, hydration and fine crepiness. It doesn't add volume or lift. For hollows or volume loss, filler or a collagen-stimulating booster such as Juvelook is a different conversation.
