Rejuran Treatment Korea: How I Repair Skin From the Inside — A Gangnam Doctor's Honest Guide

Dr. Hyunji Kim
2026-08-168 min read

Rejuran treatment Korea is one of the most searched skin treatments I see, and for good reason — it's the kind of thing that quietly makes skin look healthier rather than 'done.' But it's also widely misunderstood. Patients arrive expecting an overnight glow-up, and I have to gently reset expectations. So let me tell you honestly what Rejuran does, who it genuinely suits, and who I send elsewhere.
I'm Dr. Hyunji Kim, director at Delphic Clinic in Gangnam. I've treated thousands of local and international patients with skin boosters, and Rejuran is one I recommend often — but only when it actually fits. Here's what it really does.
What it actually is — in plain language
Rejuran is a skin booster made from polynucleotides — long chains of purified DNA fragments derived from salmon (this is the 'PDRN salmon DNA' you may have read about). We inject it in tiny amounts across the skin. It doesn't fill or plump like hyaluronic acid; instead it signals your skin to repair itself — calming inflammation, supporting collagen and elastin, and improving how the skin holds moisture. Think of it as maintenance for the skin's own repair machinery.

Here's what it isn't: Rejuran is not a filler and not a lifting treatment. It won't add cheek volume, it won't lift jowls, and it won't erase a deep nasolabial fold. If someone promises you a dramatic 'lift' from Rejuran alone, be skeptical. Its power is in skin quality — and that's a real, worthwhile thing, just a different thing.
Who it's really for
Rejuran shines for people whose main complaint is skin quality rather than shape. In my chair, the ideal candidates usually look like this:
- Dull, tired-looking skin that no cream seems to revive
- Fine lines, crepey texture, and early aging around the eyes and mouth
- Thin or fragile skin, or skin damaged by sun and years of stress
- Acne-scarred or uneven skin that needs regeneration, not just resurfacing
- Anyone wanting a natural, no-downtime way to keep skin resilient long-term
And who I steer elsewhere: if your real concern is sagging or a heavy jawline, you need a lifting treatment like Ultherapy, Thermage or threads — not Rejuran. If you want instant plumping of a specific line, a filler or a hyaluronic booster may serve you better. And if you're pregnant, breastfeeding, or have an active skin infection, we wait. I'd rather tell you the honest match than sell you the wrong course.
How it compares — an honest comparison
Patients often ask how Rejuran stacks up against other skin boosters and lifting options. Here's a simple guide — but remember the right choice is decided in person, and these are frequently combined.
In short: Rejuran repairs, HA boosters hydrate, Juvelook builds collagen, and lifting devices tighten. Different tools for different jobs — and often a smart combination beats any single one.
Before and after: what's realistic
Let me be candid about timing. After one session, most people notice a subtle freshness — that's the healing formula working, not the full effect. The real changes in texture, elasticity and that lit-from-within look build gradually over the full course, usually becoming clear around weeks 4–8. It's a slow, natural improvement, which is exactly why it looks like good skin rather than a treatment. And results genuinely vary with age, skin condition and lifestyle.

What to expect — step by step
- 1
1. Free consultation
We assess your skin honestly, confirm Rejuran is the right fit, and choose the right type (Healer, I, HB or S) and how many sessions you'll really need.
- 2
2. Numbing & prep
We cleanse the area and apply numbing cream for around 20–30 minutes so the injections stay comfortable.
- 3
3. The session
A series of fine micro-injections across the treatment area. The session itself is quick — usually 15–20 minutes of injecting.

4. Back to your day
You may see small bumps that settle within a day or two. Most patients head straight back to sightseeing or work; makeup is usually fine the next morning.

5. Results build over weeks
Skin quality improves gradually. We space sessions 2–4 weeks apart and plan maintenance once or twice a year.

How we do it at Delphic — and why it matters
With Rejuran, technique matters more than people realize — depth, spacing and the amount per injection all affect both comfort and results. Every session at Delphic is doctor-led with genuine, authentic Rejuran product, and we tailor the type and plan to your skin rather than running one fixed protocol. For patients who fear needles, we also offer a gentler, less painful Rejuran approach — ask us about it at consultation.

How much does it cost in Korea?
Rejuran pricing depends on which type suits you and how much is used — Healer is the classic repair formula, while I, HB and S target different needs. Here are our genuine prices:
| Rejuran Healer 2cc | ₩350,000$250 |
| Rejuran I 1cc | ₩250,000$180 |

Frequently asked questions
Does Rejuran hurt?
There's some discomfort — Rejuran is a series of tiny injections into the skin, and the healing formulas can sting briefly. We apply numbing cream first, and for sensitive patients we offer a gentler, less painful Rejuran option. Most people describe it as very manageable, not unbearable.
How long does Rejuran last?
The effect is cumulative rather than instant. After a full course of 3–4 sessions spaced 2–4 weeks apart, improvements in texture, elasticity and hydration typically hold for around 6–12 months. Most patients top up once or twice a year to maintain the result.
How does Rejuran compare to skin boosters like Skinvive or Juvelook?
Roughly: Rejuran (PDRN/polynucleotides) works by repairing and regenerating skin from within, so it's great for quality, texture and resilience. Hyaluronic-based boosters focus more on immediate hydration and plumping. Juvelook adds a mild collagen-stimulating effect. They're complementary — I often combine them.
Is there downtime with Rejuran?
Minimal. You may see small bumps or 'papules' at injection points for a day or two, and occasional tiny bruises. Most patients return to work or sightseeing the same day. Makeup can usually go on the next morning.
How many Rejuran sessions do I need?
It depends on your skin, but most people do 3–4 initial sessions, 2–4 weeks apart, then maintenance every 6–12 months. For a single visit from overseas we can plan around your trip and advise realistically.
How much does Rejuran cost in Korea?
See the prices in the article — Rejuran Healer, I, HB and S each have their own pricing. At Delphic you pay the exact same price as a local Korean patient.
