Rejuran Healer in Korea: The Salmon DNA Treatment Explained
If you have spent any time researching Korean skincare treatments, you have almost certainly come across the name Rejuran Healer. Often called the "salmon DNA injection" or simply "salmon injection," Rejuran Healer is one of the most popular skin-boosting procedures performed in Korean dermatology clinics today. It promises to regenerate skin from the inside out, improving texture, elasticity, fine lines, and overall skin health — without fillers and without surgery.
But what exactly is Rejuran Healer, how does it work, and is it worth traveling to Seoul for? In this guide, we break down everything you need to know about getting Rejuran Healer in Korea, including the science, the different product variants, real pricing, and what to expect during treatment.

What Is Rejuran Healer?
Rejuran Healer is an injectable skin booster that uses polynucleotides (PN) extracted from salmon DNA to stimulate your skin's natural regeneration processes. Unlike dermal fillers, which add volume beneath the skin, Rejuran works at the cellular level to help damaged skin repair itself. Think of it less as a cosmetic "fix" and more as a biological catalyst for healthier skin.
The treatment was developed in South Korea and has become a staple in Korean dermatology clinics over the past several years. It is officially classified as a medical device, meaning it can only be administered by licensed medical professionals in a clinical setting.
The Science: How Polynucleotides (PN) Work
The key active ingredient in Rejuran is PN (polynucleotide), a biopolymer derived from salmon DNA. You may also see the term PDRN (polydeoxyribonucleotide) used in similar contexts — both are DNA fragments, though PN has a higher molecular weight and longer polymer chains than PDRN.
Here is how it works in simple terms:
- Cell regeneration: When PN is injected into the dermis (the deeper layer of skin), it activates fibroblasts — the cells responsible for producing collagen and elastin. This stimulates your skin to build new, healthy tissue from within.
- Anti-inflammatory action: PN binds to adenosine A2A receptors, which helps reduce inflammation and promotes wound healing. This is why Rejuran is also effective for acne scars and damaged skin.
- Improved skin structure: Over time, the increased collagen production leads to firmer skin, reduced fine lines, smaller pores, and a more even skin tone.
The reason salmon DNA is used specifically is that its polynucleotide structure is highly biocompatible with human skin, meaning the risk of allergic reactions or rejection is extremely low.
Rejuran Variants: Healer, HB, i, and S
One of the things that confuses many first-time patients is that Rejuran is not a single product — it is a family of four injectable treatments, each designed for a specific purpose. All four share the same core PN ingredient but differ in formulation, viscosity, and target area.
Rejuran Healer (The Original)
- Composition: Pure PN (polynucleotide) — single active ingredient
- Target area: Full face
- Best for: Overall skin rejuvenation, anti-aging, texture improvement, elasticity
- Pain level: High — the thick viscosity of pure PN makes injections more painful
- Key trait: The strongest regenerative effect of all four variants
Rejuran Healer is the original and most widely used version. When Korean clinics simply say "Rejuran," they typically mean this product. It is injected across the entire face and delivers the most potent skin regeneration effects.
Rejuran i (Eye)
- Composition: PN in a thinner, more diluted formulation
- Target area: Under-eye and periorbital area only
- Best for: Dark circles, under-eye hollowness, fine crow's feet, eye-area elasticity
- Pain level: Moderate
- Key trait: Specifically formulated for the delicate skin around the eyes
The skin around the eyes is much thinner than the rest of the face, so standard Rejuran Healer would be too thick and could cause visible bumps. Rejuran i solves this with a lighter formulation that absorbs smoothly into the eye area.
Rejuran HB+ (The "Painless" Option)
- Composition: PN + hyaluronic acid (HA) + lidocaine (local anesthetic)
- Target area: Full face
- Best for: Patients who want Rejuran benefits but cannot tolerate the pain of standard Healer
- Pain level: Low — lidocaine provides numbing, HA smooths the injection
- Key trait: Often called "painless Rejuran" in Korean clinics
Rejuran HB+ was developed specifically to address the biggest complaint about the original Healer: pain. By adding hyaluronic acid and lidocaine to the formula, the injection process is significantly more comfortable. The added HA also provides an extra hydration and glow effect. The regenerative results are very similar to the original Healer, though some practitioners consider the pure PN formulation slightly more potent.
Rejuran S (Scar)
- Composition: PN in a high-viscosity, gel-like formulation
- Target area: Specific scar sites (acne scars, pitted scars)
- Best for: Depressed or atrophic scars
- Pain level: Moderate
- Key trait: Thicker consistency allows it to fill and regenerate scar tissue directly
Rejuran S is not injected across the face — it is placed directly into individual scars. The higher viscosity means it stays in place within the scar tissue and promotes targeted regeneration and collagen remodeling.
Quick Comparison Table
| Variant | Active Ingredients | Target Area | Pain Level | Best For |
|---|---|---|---|---|
| Healer | PN (pure) | Full face | High | Overall skin rejuvenation |
| i (Eye) | PN (diluted) | Eye area | Moderate | Dark circles, eye wrinkles |
| HB+ | PN + HA + lidocaine | Full face | Low | Pain-sensitive patients |
| S (Scar) | PN (high viscosity) | Scar sites | Moderate | Pitted and atrophic scars |
How Much Does Rejuran Cost in Korea?
One of the biggest reasons international visitors get Rejuran in Korea is the price. Treatments in Seoul are significantly more affordable than in the US, Europe, or Australia.
Here are current average prices based on Korean medical platforms (as of early 2026):
| Treatment | Price per 1cc | Typical Session (2-4cc) | USD Equivalent |
|---|---|---|---|
| Rejuran Healer | ~₩120,000 | ₩240,000–₩500,000 | $185–$385 |
| Rejuran i | ~₩120,000–₩165,000 | ₩120,000–₩165,000 (1cc) | $90–$125 |
| Rejuran HB+ | ~₩130,000 | ₩260,000–₩520,000 | $200–$400 |
| Rejuran S | ~₩130,000 | Varies by scar area | $100–$300 |
For a full-face Rejuran Healer session using the recommended 4cc, expect to pay approximately ₩400,000–₩650,000 ($300–$500). Many clinics offer package deals for the recommended 3-session course, which can bring the per-session cost down considerably.
By comparison, a single Rejuran session in the US or Australia typically costs $700–$1,200, meaning you can save 50-60% by getting the treatment in Seoul.
Prices as of February 2026. Actual costs vary by clinic, location, and promotional events. Exchange rate: ₩1,300 ≈ $1 USD. Contact clinics directly for current pricing.
What to Expect: The Treatment Process
Before Your Appointment
- Avoid retinol, exfoliating acids, and scrubs for 2-3 days before treatment
- Keep your skin well-moisturized to strengthen the skin barrier
- Inform your doctor of any allergies, medications, or skin conditions
During the Procedure
- Cleansing: Your face is thoroughly cleansed and disinfected
- Numbing: A topical anesthetic cream is applied for 20-30 minutes (especially important for Rejuran Healer, which is the most painful variant)
- Injection: The doctor injects Rejuran into the dermis using either a manual hand injection technique or a meso-gun device. The procedure takes approximately 15-30 minutes
- Post-treatment care: A soothing mask or calming cream may be applied
After Treatment: What to Expect
- Embossing bumps: Small raised bumps will appear at each injection site immediately after treatment. This is completely normal and is sometimes called the "Rejuran embossing" effect. These bumps typically flatten and absorb within 2-3 days
- Redness and swelling: Mild redness is common for 1-2 days
- Bruising: Some patients experience minor bruising, which fades within a week
- Results timeline: According to data from Korean medical platform Goodoc, 59% of patients notice improvement immediately after treatment, 36% see results within one week, and the remaining 5% within one month. Full effects develop gradually over 2-4 weeks as collagen production ramps up
Recommended Treatment Schedule
Korean dermatologists typically recommend:
- Initial course: 3-4 sessions, spaced 2-4 weeks apart
- Maintenance: 1 session every 3-6 months after completing the initial course
- Duration of results: With the full recommended course, effects can last 6 months to 1 year
Who Is a Good Candidate?
Rejuran Healer works well for a wide range of skin concerns and is suitable for most adults. It is particularly popular among patients in their 20s to 40s in Korea. You may be a good candidate if you have:
- Dull, tired-looking skin that lacks radiance
- Fine lines and early wrinkles, especially around the eyes and forehead
- Enlarged pores or rough skin texture
- Mild acne scarring or post-inflammatory damage
- Loss of skin elasticity and firmness
- Chronic dryness that does not respond to topical products alone
Rejuran is not recommended for patients who are pregnant or breastfeeding, those with active skin infections, or anyone with a known allergy to fish or fish-derived products.
Tips for International Visitors
Getting Rejuran in Seoul as a foreign visitor is straightforward, but here are some practical tips:
- Choose a clinic in Gangnam or Apgujeong: These areas have the highest concentration of dermatology clinics, many with English-speaking staff
- Book through medical tourism platforms: Apps like Gangnam Unni and Yeoshin Ticket list verified clinics with reviews, pricing, and sometimes discounted packages
- Plan for downtime: While Rejuran is a "lunchtime procedure" with minimal downtime, the embossing bumps last 2-3 days. Schedule your session at least 3 days before any major events or travel
- Ask about combination treatments: Many Korean clinics pair Rejuran with other skin boosters, lasers, or LED therapy for enhanced results at a bundled price
Frequently Asked Questions
Q: Does Rejuran Healer hurt? A: The original Rejuran Healer is known for being one of the more painful skin booster treatments due to the thick viscosity of the PN formulation. Most clinics apply a topical numbing cream for 20-30 minutes before injecting. If pain is a major concern, ask about Rejuran HB+, which contains a built-in anesthetic and is significantly more comfortable.
Q: How long do Rejuran results last? A: After completing the recommended 3-4 session initial course, results typically last 6 months to 1 year. Individual results vary depending on skin condition, age, and lifestyle. Maintenance sessions every 3-6 months help extend the effects.
Q: Can I combine Rejuran with other treatments? A: Yes. Korean clinics frequently combine Rejuran with treatments like Shurink (HIFU), laser toning, or other skin boosters. Your dermatologist can design a combination protocol based on your specific goals. Most clinics recommend spacing different treatments at least 1-2 weeks apart.
Q: Is there any risk of allergic reaction from salmon DNA? A: Reactions are extremely rare because the PN in Rejuran is highly purified and biocompatible. However, if you have a documented allergy to fish, inform your doctor before treatment so they can assess whether Rejuran is appropriate for you.
Q: What is the difference between Rejuran and other skin boosters like Profhilo? A: While both are injectable skin boosters, they work differently. Rejuran uses polynucleotides (salmon DNA) to stimulate cellular regeneration and collagen production. Profhilo uses concentrated hyaluronic acid to deeply hydrate and remodel tissue. Some patients benefit from both — Rejuran for regeneration and Profhilo for hydration.
Q: Can I wear makeup after Rejuran? A: It is recommended to avoid makeup for at least 24 hours after treatment to let the injection sites heal and reduce infection risk. After 24 hours, you can resume your normal skincare and makeup routine.
