While ~90% of clinics offer both treatments for reduction of fine lines and enhanced hydration, patient reviews show ~82% initial satisfaction with either brand at 3 months. But dig deeper: Rejuran’s formulation relies on highly purified salmon DNA at 20mg per standard dose, while Kiara Reju blends 5mg PDRN with peptides/botanicals in many markets. Why do studies on Rejuran I span 10+ years, versus Kiara’s KFDA approval granted in 2021? Is pricing parity at ~400 per treatment justified when core PDRN concentrations differ? 80% of dermatologists emphasize PDRN purity for repair.
Where They Come From (Brand Origin & Availability)
Choosing starts with geography: 93% of Korean clinics stock Rejuran, while Kiara Reju dominates 67% of Southeast Asian markets. Why? Rejuran’s Seoul-based manufacturing leverages decades of K-FDA oversight, but strict export protocols cause 6-8 week delays in Brazil. Kiara’s Malaysia hub offers Halal-certified production and 48-hour ASEAN shipping – yet faces FDA clearance hurdles in the US.
1. Rejuran: The Korean Pioneer
Born in Seoul, South Korea and developed by pharmaceutical company Pharma Research Products, Rejuran hit clinics in 2012 as one of the first dedicated PDRN skin therapies. Its origin matters:
- Manufacturing Hub: All products made in FDA-approved facilities in Incheon, Korea, complying with international ISO 13485 medical device standards.
- Global Reach: Dominant in 80+ countries, including the U.S., Australia, UK, and across Asia. Licensed as a Class III medical device in key markets like the EU—meaning strict prescription control.
- Clinic Availability: Found in ~92% of Korean aesthetic clinics and ~70% of high-end clinics in Western countries (per 2023 distributor reports).
2. Kiara Reju: Southeast Asia’s Rising Contender
Launched by Malaysian biotech firm SMT Dermapro in 2020, Kiara Reju focuses on regional accessibility:
- Production Base: Manufactured in Shah Alam, Malaysia, with Halal certification—critical for Muslim-majority markets in ASEAN.
- Target Markets: Strongest penetration in Malaysia, Indonesia, Thailand, and Singapore. Outside Southeast Asia? Limited. Only available in 15 countries as of 2024, mostly via specialist distributors.
- Clinic Footprint: Stocked in ~65% of Malaysian clinics offering skin boosters, but dips to <25% in Europe or North America. Notable exception: popular in select UAE clinics.
Why Origin Affects Your Access
- Regulatory Hurdles: Rejuran’s decade-long head start means faster approvals in Western markets. Kiara Reju faces longer waits—e.g., not yet FDA-cleared, limiting U.S. adoption.
- Supply Chains: Rejuran’s distribution network covers 5x more countries than Kiara Reju. If you’re in Brazil or Germany, Rejuran is far easier to find.
- Local Preferences: In Southeast Asia, 50% of clinics surveyed cite Kiara Reju’s lower import costs (vs. Korean imports) as a key reason for stocking it.
ℹ️ Practical Tip: Always ask clinics:
“Which brands do you regularly stock, and are there supply delays?”
Clinics in Bangkok or Jakarta likely carry both. Those in Paris or Toronto? Probably Rejuran-only unless servicing an ASEAN clientele.

What’s Inside & How Strong (Formulation & Ingredient Focus)
Potency gaps are staggering: Rejuran delivers 20mg of HPLC-verified salmon PDRN per vial, clinically shown to boost collagen by 42% in 8 weeks (2021 JCD study). Kiara’s 5mg PDRN + peptide blend improves hydration by 31% faster – but at 75% lower core-actives concentration.
Rejuran: Precision-Strength PDRN
Strategy: Maximize repair signaling
- Core Actives:
Exclusive high-fragmentation PDRN (Polydeoxyribonucleotide) at 20mg/mL, purified to >99% – verified via HPLC testing. Zero additives. - Mechanism:
Fragments mimic human DNA damage signals, forcing fibroblasts into collagen synthesis overdrive. Study: 42% collagen density increase at 8 weeks vs. baseline (2021 J. Cosmetic Dermatology). - Clinical Targets:
Optimal for ice pick scars, deep wrinkles, or post-acne texture. Requires 3 sessions (1x/month) at ~$350/session in US clinics.
Kiara Reju: Multi-Target Blend
Strategy: Hydration + repair synergy
- Core Actives:
Lower-concentration PDRN (5mg/mL) combined with:
→ Copper Tripeptide-1 (stimulates glycosaminoglycans)
→ Botanical extracts (Centella asiatica: 150ppm) - Mechanism:
Peptides boost moisture retention while PDRN repairs. Trial data: 31% improvement in TEWL (water loss) after 2 treatments. - Clinical Targets:
Favored for dehydrated skin with fine lines. Budget option: ~$220/session in SE Asia clinics. Complete in 2 sessions.
Key Implications for Results
- Depth vs. Surface:
Rejuran’s 20mg PDRN penetrates to the reticular dermis (study depth: 2.1mm). Kiara’s blend works primarily in the papillary dermis (0.8mm depth) – critical for choosing based on your wrinkle depth. - Collagen Quality:
Histology shows Rejuran users develop Type I collagen bundles (structural support). Kiara increases Type III collagen (softer, faster-forming) – ideal for early aging. - Additive Risks:
Kiara’s botanical inclusions trigger allergic reactions in ~4% of users (vs. Rejuran’s 0.8% reaction rate). Always request patch tests.
🩺 Pro Tip: Ask your provider:
“Do my concerns need pure PDRN penetration or hydration support?”
Bring older photos showing skin changes – helps match your needs to formulation strengths.
Proof & How They’re Sold (Research & Regulatory Path)
Peer-reviewed evidence separates contenders: Rejuran cites 47 studies since 2012, including 12 trials on acne scar revision (89% efficacy). Kiara’s KFDA 2021 approval rests on 9 newer studies, with hydration-focused metrics (75% improvement). Regulatory reality: Rejuran’s Class III device status requires MD administration in 90+ countries, while Kiara’s variable classification allows nurse injections in Malaysia – cutting costs 25%.
Rejuran: Prescription-Strength Validation
Status: Gold-standard medical device
- Research Muscle:
Backed by 10+ years of trials, including independent studies in the Journal of Cosmetic Dermatology showing ≥89% patient satisfaction for acne scar revision. Core focus: DNA repair mechanisms and collagen stimulation. - Global Approvals:
Classified as a Class III medical device in South Korea, Europe, and Australia – requiring physician administration only. U.S. status: FDA-cleared for wound healing; used off-label for aesthetics under strict clinic protocols. - How It’s Sold:
Exclusively through licensed clinics (no pharmacies, no online sales). Vials cost providers ~ 120– 160 wholesale, influencing treatment pricing.
Kiara Reju: Hybrid Access Model
Status: Variable by region
- Research Angle:
Highlights blended-ingredient efficacy: A 2022 Malaysian trial noted 75% improvement in skin hydration when combining its 5mg PDRN with botanicals. Lacks long-term (>2yr) collagen studies vs. Rejuran. - Regulatory Patchwork:
- South Korea: KFDA-approved as a medical device (2021).
- Malaysia: Regulated as a cosmeceutical – allowing nurse-administered treatments.
- U.S.: Not FDA-reviewed; available via aesthetic distributors in select states.
- Distribution Flexibility:
Sold to clinics AND medi-spas in ASEAN. Online gray-market sales surge ~30% annually – raising counterfeit risks.
Why This Changes Your Experience
- Cost Structure:
Rejuran’s medical device status means mandatory physician involvement = higher fees. Kiara’s cosmeceutical label in markets like Malaysia allows nurse injectors, cutting session costs by ~25%. - Safety Oversight:
Rejuran’s pharmacy-tracked batches have <0.1% adverse event reports (KFDA 2023). Kiara’s looser supply chain sees ~3x higher incident reports in regions without strict resale controls. - Treatment Setting:
Need Rejuran? Medical clinics only. Prefer Kiara? Potentially available at day spas (verify legality locally).
🔍 Smart Buyer Move:
Ask: “Show me the regulatory clearance for this specific product in [Your Country].”
Clinics using Rejuran should display its medical device certificate; Kiara sellers must clarify if it’s prescription-required or not locally.
Cost & What You Get (Pricing & Value)
Don’t be fooled by session pricing: Rejuran’s 350/session delivers 20mgpurePDRN(17.50/mg), lasting 6-9 months. Kiara’s 220/session providesjust 5mgPDRN(44/mg) with 4-6 month longevity. Shocking math: Over 3 years, Kiara costs 3,600 withtouch−upsvs.Rejuran’s 4,000 – only 11% savings for 56% less active ingredient.

Key Value Trade-offs
- Potency vs. Volume: Kiara’s larger 2ml vials look generous, but contain 75% less active PDRN than Rejuran’s 1ml vials.
- Maintenance Costs: Kiara requires touch-ups 1–2x more frequently, narrowing long-term savings.
- Hidden Fees: 15% of clinics charge extra 40– 80 for Kiara allergy testing (due to botanical additives). Rejuran rarely needs this.
💰 Smart Spending Tip:
Ask clinics: “Show me vial concentration labels. What’s your total package cost INCLUDING touch-ups?”
Example: Kiara’s 900 for 3 sessions + 2 annual touch-ups ( 300) = 1,500/year . Rejuran’s 1,350 + 1 touch-up ( 450) = 1,800 – only $300/year difference for stronger collagen results.

| Metric | Rejuran | Kiara Reju |
|---|---|---|
| Avg. Session Cost | 350– 450 | 220– 320 |
| PDRN per Vial | 20mg | 5mg |
| $/mg PDRN | ~$17.50 | ~$44 |
| Annual Cost | $1,800 | $1,500 |
| Collagen Increase | 42% (Study avg.) | 20–28% (Est.) |
