"Is one session of Rejuran enough if I'm only in Seoul for a week?"
"Will I be red and swollen in all my holiday photos?"
"Should I get Rejuran or the other one, Forjuran?"
If you are planning Rejuran Healer in Korea, you have probably seen it on almost every Seoul skin clinic's menu. What is harder to find is a plain answer to how many sessions it takes, how they fit into a trip, and whether it suits your skin at all.
This post is worth a few minutes before you book, because Rejuran is a treatment that works over a course of sessions, and that changes how you should plan your visits.
By the end you will know:
- what Rejuran is made of and what it does in the skin
- who it suits, and when Forjuran may suit you better
- how many sessions are recommended and how to spread them across trips
- what the day of treatment and the days after look like
- what decides the cost and what to ask any clinic
Who is writing this
I am Dr. Im Jung-woo, representative director of LAHYEON Plastic Surgery in Cheongdam, Seoul. I am a board-certified general surgeon. I trained at Samsung Medical Center (Sungkyunkwan University), where I also served as an adjunct professor of surgery. Most of my writing is about body surgery, but the principles I apply there apply to skin treatment as well: diagnose accurately, plan one to one, do only as much as is needed, and use only genuine, approved products. More about me is on my doctor page.
I am writing this because Rejuran is often booked as a one-off on a short trip, and I would like you to know what a realistic course looks like.
What is Rejuran Healer?
Rejuran Healer is an injection of PN, or polynucleotide, into the dermis. PN is a biocompatible material made by cutting DNA into fragments of a set size. Rejuran's PN is extracted and purified from salmon, whose DNA composition is close to human DNA. It is stable under heat and does not act as a foreign body.
What does it do in the skin?
Injected into the dermis, PN improves the conditions inside damaged skin. It helps rebuild skin structure, induces collagen and increases the thickness and elasticity of thin, loose skin that has been damaged by aging, UV and irritation.
The product material we work from reports that dermal density and thickness increased by 15 to 30% on average 4 weeks after treatment, with the eye and cheek areas improving the most. Your own result will vary. Change appears gradually from about 2 weeks. It also helps balance oil and moisture, with less sebum and smaller-looking pores.
So Rejuran works on the structure of the skin. It is a different goal from adding moisture for a quick glow.
Who is Rejuran Healer for?
It tends to suit you if:
- your skin is thin, sensitive or damaged
- fine lines and a slight loss of elasticity show around the eyes and cheeks
- you have redness and want calmer skin
- you want to improve skin structure, not only hydration
- you need to wash your face and wear makeup the same day
Is Rejuran Healer & Forjuran right for you?
Tap what applies. We turn it into an inquiry, and our team replies with suggested next steps for your trip.
Hello, I'm interested in Rejuran Healer & Forjuran at LAHYEON Plastic Surgery. Could you suggest a plan for me?
No booking until you confirm.
Rejuran Healer or Forjuran?
We offer both, and the choice depends on your skin and what you want.
Rejuran Healer contains PN only. It aims at skin regeneration, dermal structure and texture. Improvement builds gradually after 2 to 3 sessions. Some redness or swelling may appear. We recommend 3 sessions, 3 to 4 weeks apart. It usually suits sensitive or damaged skin with many fine lines.
Forjuran contains PN plus 56 nutrients. It aims at regeneration, brightening, hydration, elasticity and glow together. Tone and firmness can improve from the first session, with less swelling and quicker recovery than Rejuran. We recommend 3 sessions, 2 to 3 weeks apart. It usually suits dull, dry skin lacking firmness and glow.
The two can also be combined with a gap between them, for example Rejuran first for base regeneration, followed by Forjuran.
If you are short on time in Seoul and want to see a change in tone sooner, Forjuran may fit your trip better. If your skin is thin, reactive and lined, Rejuran's slower structural work is usually the better starting point. I recommend one after looking at your skin.
What happens on the day?
- Skin check, and a decision between Rejuran and Forjuran.
- Numbing cream for about 30 minutes.
- The product is checked with you, then injected. This takes about 10 to 20 minutes.
- You can wash your face and put on makeup the same day.
Most people feel a mild sting during the injections. Forjuran tends to cause less swelling and less pain.
We use only products approved by MFDS, Korea's Ministry of Food and Drug Safety, and we check the product with you from opening to injection. I would encourage you to ask for this wherever you go.
How Lahyeon runs a Rejuran course
The way a clinic runs Rejuran matters as much as the product, because the same PN can be given as a quick add-on or as a planned course. At Lahyeon it works like this:
- A specialist doctor performs the injection directly. It is not handed off once the plan is made.
- The plan starts with a skin analysis. Thin, reactive skin and dull, dry skin get different products and intervals, so the choice between Rejuran and Forjuran comes after the analysis.
- The course is set out step by step. You know at the first visit how many sessions are planned and roughly when each one falls, which is what lets you book trips around it.
- Only as much as needed. If your skin needs one product, you are not sold both. Combining them is suggested only when your skin calls for it.
- Follow-up care continues after treatment. Ask before you leave how to reach us if redness or bruising lasts longer than expected.
Planning your trip to Seoul
How many sessions fit into one trip?
This is the part to plan honestly. Rejuran is recommended as 3 sessions 3 to 4 weeks apart, and Forjuran as 3 sessions 2 to 3 weeks apart. A one-week trip fits one session.
That leaves you a few realistic options:
- Have one session per trip and return for the next ones at the recommended interval.
- If you are staying in Korea for longer, complete the course during that stay.
- Choose the product with the interval that fits your travel, after we look at your skin.
One session is a start. Improvement with Rejuran builds over sessions, so please do not judge it on one alone.
Recovery timeline
| Time after treatment | What to expect |
|---|---|
| Day 1 | Wash your face and wear makeup the same day. Temporary redness, swelling or bruising can occur. |
| Days 2–3 | Redness, swelling or bruising usually clears. |
| Week 2 | Change starts to appear gradually. |
| Weeks 2–4 | Next session, depending on the product: Forjuran after 2–3 weeks, Rejuran after 3–4 weeks. |
| Months 3–6 | After 3–4 sessions, the effect usually lasts about 3–6 months. Regular maintenance helps keep the skin in good condition for longer. |
How long should you stay in Korea?
Because you can wash and wear makeup the same day, Rejuran fits a short stay. If you want to avoid visible redness or bruising in photos, schedule it a few days before any important plans rather than the day before.
Flying home and aftercare at home
Ask us if you have any concern about flying soon after treatment. Keep your normal gentle skin care, and plan your next session at the recommended interval. If you would like to know which interval to aim for, ask us before you leave.
