What Is Rejuran? (No Marketing Fluff)
If you've spent any time in Korean skincare circles, you've heard about Rejuran — also called the "salmon DNA injection" or 아기피부주사 (baby skin injection). Strip away the marketing: Rejuran is an injectable skin booster made from polynucleotides (PN) extracted from salmon DNA. It's manufactured by Pharma Research Products in Korea and has been KFDA-approved since 2014. Over a decade of clinical use means this isn't experimental — it's one of the most battle-tested non-surgical aesthetic treatments in the Korean market.
What it actually does: the polynucleotides stimulate your skin's fibroblasts — the cells responsible for producing collagen, elastin, and hyaluronic acid. Unlike fillers that add volume from outside, Rejuran triggers your skin to repair itself from within. Think of it as giving your skin the biological raw materials to rebuild its own structure, not just a temporary cosmetic patch.
The science is legitimate. Multiple peer-reviewed studies in Korean and Japanese dermatology journals show measurable improvements in skin elasticity (up to 25%), hydration, and fine line reduction after a 3-session protocol. But let's be clear about limitations: Rejuran won't replace surgical intervention for deep wrinkles, significant sagging, or structural changes. It's a skin quality treatment — not a facelift alternative. If your concern is volume loss or severe ptosis, you need different procedures.
Why Korea matters: this is where the product was developed, where dermatologists have performed more Rejuran sessions than anywhere else on earth, and where you're guaranteed the original formulation. In other countries, clinics sometimes use generic PN products with 10–15% lower polynucleotide concentrations — which means more sessions for comparable results. In Korea, you get the source product at the source price.
Rejuran Types: Healer vs. HB vs. Eye vs. S
Most English-language guides treat "Rejuran" as a single product. It's not. There are four distinct formulations, and choosing the wrong one wastes money. Here's the honest breakdown — the same information Korean patients get but that rarely appears in foreigner-facing marketing.
| Type | Best For | Key Difference |
|---|---|---|
| Rejuran Healer | General anti-aging, skin quality | Standard PN formula, 2cc full-face |
| Rejuran HB | Dry / dehydrated skin | PN + hyaluronic acid + lidocaine |
| Rejuran Eye (i) | Under-eye aging | Lower viscosity, finer needle gauge |
| Rejuran S | Acne scars, localized damage | Higher viscosity for targeted injection |
Prices are similar across all four. Choice should be based on skin concern, not cost.
Rejuran Healer — The Default
This is the original and most widely used version. Pure polynucleotide injection for general skin rejuvenation: texture improvement, fine line reduction, radiance. If your primary concern is "my skin looks tired and dull," Healer is what you want. Standard dosage is 2cc for full-face treatment. If a clinic offers Healer with less than 2cc for a full face, they're under-dosing — ask questions.
Rejuran HB — The Hydration Version
HB combines polynucleotides with hyaluronic acid, delivering both regenerative and immediate hydrating effects. It also contains lidocaine, making injections less painful — relevant if you have low pain tolerance. If your skin barrier is compromised — flaky, tight, perpetually dehydrated despite topical products — HB is your better starting point. The hydration effect is more immediately visible, making it popular as a pre-event treatment. Often compared to other skin rejuvenation treatments available in Korea.
Rejuran Eye (i) — Under-Eye Specialist
The periorbital area has the thinnest, most delicate skin on your face. Standard Rejuran injected here would create obvious bumps that take too long to resolve. Rejuran Eye uses a lower-viscosity formula and finer-gauge needle specifically for under-eye treatment — targeting dark circles, fine lines, and crepey texture without visible papule formation. If under-eye aging is your primary concern, this is the one to ask about.
Rejuran S — The Scar Fighter
Rejuran S has higher viscosity for precise, localized injection directly into acne scars. Rather than treating the entire face, the dermatologist targets each scar to promote tissue regeneration at that exact spot. Clinical data shows 60–80% improvement in rolling and boxcar-type acne scars after 2–3 sessions. If acne scarring is your main issue, Rejuran S combined with fractional laser is one of the most effective non-surgical approaches in Korean dermatology. Part of the broader K-beauty treatment ecosystem that draws patients worldwide.
Real Seoul Prices (2026)
Rejuran pricing in Seoul varies by clinic location, doctor seniority, and whether you're getting genuine Pharma Research Products Rejuran or a cheaper generic PN product. Here's what our survey of 30+ Seoul dermatology clinics found:
| Treatment | Price Range | Notes |
|---|---|---|
| Rejuran Healer (2cc) | ₩300,000–₩500,000 | Full face, single session |
| Rejuran HB (1cc) | ₩250,000–₩400,000 | Hydration + HA + lidocaine |
| Rejuran Eye (1cc) | ₩250,000–₩350,000 | Under-eye area only |
| Rejuran S (1cc) | ₩250,000–₩400,000 | Scar treatment, per session |
| 3-Session Package | ₩800,000–₩1,200,000 | Saves 15–25% vs. singles |
| Healer + Eye Combo | ₩500,000–₩750,000 | Full face + under-eye same day |
Source: ClinicSeoul.net 30+ clinic Seoul survey, March 2026. ₩1,300 ≈ $1 USD.
Important context. First, Gangnam and Apgujeong clinics charge 10–20% more than Hongdae, Jongno, or Myeongdong — you're paying for the ZIP code. Second, Rejuran under ₩200,000 almost always means generic PN, not authentic Rejuran. The product cost alone makes genuine Rejuran unprofitable at that price. Ask: "정품 리쥬란인가요?"
Third, foreigner pricing exists. Some clinics add 10–15% for international patients — standard across Korean aesthetic medicine. Workaround: choose clinics that post prices publicly on Naver or Instagram rather than "consultation-based" pricing. Compare against our master price list for benchmarks.
Korea vs. Global Pricing
This is the clearest argument for booking Rejuran in Korea. Same product, same technique, dramatically different price tags.
Per-session pricing. Korea package = per-session cost in 3-session bundle.
You can complete a full 3-session protocol in Seoul for roughly the cost of a single session in Sydney. Factor in a budget flight and a few nights' accommodation, and you're still ahead — especially if you combine Rejuran with other treatments during the same trip. Check our tour package guide for trip planning frameworks. This pricing gap is why Rejuran has become one of the top reasons skin-focused medical tourists visit Korea.
What the Procedure Is Actually Like
Never had injectables before? Here's the unfiltered walkthrough.
Consultation (10–15 min). At foreigner-friendly clinics, an English-speaking coordinator guides you. The dermatologist examines your skin — sometimes using a VISIA analysis device — and recommends Rejuran type and dosage. Good clinics explain why they're choosing Healer vs. HB vs. Eye for your situation. Assembly-line clinics push whatever they're promoting that month.
Numbing (20–30 min). Topical anesthetic cream across your face. You wait. Some clinics give you a private room; others line up chairs with everyone in various numbing stages. Use this time to verify the product — ask to see the sealed Rejuran syringe. Genuine Rejuran has distinct packaging with a holographic authentication sticker.
Injections (15–30 min). The dermatologist uses a fine-gauge needle or automated mesotherapy device to deliver micro-injections across the treatment area. You'll feel pressure and mild stinging despite numbing. Forehead and cheeks are tolerable; under-eye and upper lip are where people wince.
Immediate aftermath. Your face is covered in small papules (raised bumps) at every injection point — normal. These are Rejuran product sitting in the dermal layer before absorption. They flatten in 1–3 days. Face will be red and slightly swollen. Most clinics apply soothing serum or LED mask post-treatment.
Downtime: Minimal but not zero. Makeup OK next day. Redness resolves in 24–48 hours. Papules visible 1–3 days (noticeable close-up, not from a few feet away). Avoid alcohol, intense exercise, saunas 24 hours. No pools 3 days. SPF 50+ diligently. No bandages, no stitches. Compare this to surgical recovery timelines and you'll see why Rejuran is so popular with medical tourists on tight schedules.
Honest Results Timeline
Rejuran is not Botox. No instant transformation. The changes are gradual, cumulative, and happen below the surface before showing on it.
After session one, the first noticeable change is hydration — plumper, softer skin with a subtle glow within 7–14 days. Real structural changes — firmer texture, fine line reduction, more even tone — take 2–3 months as fibroblasts produce new collagen. Peak results at month 3–4 after all 3 sessions. Effects diminish over 6–12 months depending on age, lifestyle, and sun exposure.
What Rejuran won't fix: deep nasolabial folds (you need fillers), significant jowling (that's surgical territory), active inflammatory acne (treat that first), or dramatic skin lightening. If someone promises miraculous results from Rejuran alone, find a different clinic.
How to Choose a Clinic (Red Flags)
Seoul has over 1,200 licensed aesthetic clinics. Quality varies enormously. Here's how to filter:
Go to a dermatologist, not a plastic surgeon. Rejuran is a dermatological procedure. In Korean: 피부과 (pi-bu-gwa) = dermatology. 성형외과 (seong-hyeong-oe-gwa) = plastic surgery. For Rejuran, you want 피부과. A great plastic surgeon doesn't necessarily mean great injector skills.
Verify injection volume. Standard full-face Rejuran Healer = 2cc. Budget clinics use 1cc to cut costs, then push "more sessions." Ask before treatment: "몇 시시예요?" (How many cc?). If they dodge, leave.
Check product packaging. Ask to see the sealed syringe before they open it. Genuine Pharma Research Products Rejuran has distinct packaging with holographic sticker. Generic PN products aren't inherently terrible — but they're not Rejuran, and you shouldn't pay Rejuran prices for them.
Red flag: "Pricing only after consultation." Reputable clinics give you a price range upfront. Clinics that refuse until you're seated are more likely to upsell or apply foreigner markup. Get quotes from 2–3 clinics via KakaoTalk first.
Red flag: Under ₩200,000 for Healer 2cc. Product cost alone makes this unprofitable with genuine Rejuran. At that price, you're getting generic PN — possibly with 10–15% lower concentration. Better to pay ₩350,000 for the real product.
Best Treatment Combinations
Korean dermatology's real advantage: sophisticated multi-treatment protocols. The most effective Rejuran combinations, as actually recommended by Korean dermatologists:
Rejuran + Botox
Rejuran rebuilds skin quality; Botox relaxes dynamic wrinkles. Different mechanisms, additive results. Same-day OK. Most popular combo for 30+ patients.
Rejuran + Laser Toning
Laser targets pigmentation, pores, surface texture. Rejuran handles deeper regeneration. Space 1–2 weeks apart. The "Korean glass skin" protocol.
Rejuran + Juvelook
Juvelook (PDLLA + HA) stimulates collagen via different pathway. Dual-stimulation approach trending in 2026. Same-day possible at some clinics.
Rejuran + Thread Lift
Thread lift provides mechanical lift; Rejuran improves the skin on top. For 35+ patients needing both. Space 2 weeks minimum.
Plan a 7–10 day trip: Rejuran on day 1–2, laser mid-trip, Botox/filler toward the end. Many Gangnam clinics offer combo packages priced 15–20% below individual costs. See our guides on optimal treatment timing and aftercare protocols.
Pros, Cons & Who Should Skip It
✓ Strengths
- Genuine skin regeneration — not just cosmetic masking
- Evidence-backed, 10+ years of clinical data
- Minimal downtime (1–3 days papules)
- Compatible with virtually all other treatments
- Korea prices 50–75% below global average
- Safe across all skin types (Fitzpatrick I–VI)
- No risk of "frozen face" or overfilling
✗ Limitations
- Results take 2–3 months — no instant gratification
- Requires 3 sessions for full effect (cost × 3)
- Won't fix deep wrinkles, sagging, or volume loss
- Duration 6–12 months — not permanent
- Papules visible 1–3 days post-treatment
- Generic PN flood the market — verification needed
- Under-eye injections can bruise (1–2 week resolution)
Best candidates: Anyone 25+ wanting to improve overall skin quality — texture, elasticity, hydration, mild fine lines. Especially valuable for skin that looks "tired" despite good topical care. Also excellent as pre-treatment before more aggressive procedures like Ultherapy or laser resurfacing — healthier skin recovers better.
Skip if: You expect dramatic, visible transformation from one visit. If your concerns are structural — deep folds, jowls — money is better spent on targeted procedures. Also skip during pregnancy, breastfeeding, or active skin infection.
Foreign Patient Logistics
Booking: Walk-ins work, but book 1+ week ahead via KakaoTalk for specific doctors. Send bare-face photos, specify Rejuran, ask for single + package pricing. If no response in 48 hours, move on — pre-booking communication predicts post-treatment support. More in our timing guide.
Payment: Cash = 5–10% discount at most clinics. International Visa/Mastercard accepted everywhere. Don't pay deposits until product type, dosage (cc), and total cost are confirmed in writing. See financing options.
Tax refund: Foreigners get ~5–7% medical tax refund. Ask for "세금 환급 영수증" (tax refund receipt). Process at Incheon Airport before departure. Details in our hidden costs guide.
Trip planning: Single session = zero downtime, sightsee same day. Full 3-session protocol = 3–4 week stay, or 2–3 trips. Many tourists do session 1 in Korea, sessions 2–3 at home — works if your local provider uses genuine Rejuran. See tour package guide for itinerary templates.
Language: Gangnam/Myeongdong = English coordinators usually available. Elsewhere = Korean only. Papago app handles 90% of communication. For full English service, expect higher prices — but for a 15-minute largely non-verbal procedure, language rarely matters much.
Insurance: Rejuran is cosmetic — no insurance coverage anywhere. All out-of-pocket. Silver lining: Korea's cash prices are lower than insured copays in many Western countries.
