What is Rejuran Injection and How Does it Work
Rejuran is a medical-grade injectable containing polydeoxyribonucleotide (PDRN) extracted from salmon DNA. The molecular structure of salmon DNA closely resembles human DNA, allowing for high biocompatibility and minimal rejection risk. Korean pharmaceutical company Pharma Research Products developed Rejuran specifically for dermal regeneration, receiving approval from Korea’s Ministry of Food and Drug Safety (MFDS) in 2015.

The treatment works through multiple biological mechanisms. PDRN fragments stimulate adenosine A2A receptors in skin cells, promoting fibroblast proliferation and collagen synthesis. Research published in the International Journal of Molecular Sciences demonstrates that PDRN enhances wound healing by increasing vascular endothelial growth factor (VEGF) production. This creates improved microcirculation and accelerates tissue repair at the cellular level. See also: /p>
Unlike hyaluronic acid fillers that provide volume, Rejuran focuses on fundamental skin quality improvement. The treatment targets skin thickness, elasticity, hydration, and overall texture. Korean dermatologists classify it as a “skin healer” rather than a “skin filler,” making it particularly effective for conditions like acne scars, enlarged pores, fine lines, and skin laxity.
The injection contains PDRN molecules sized at 50-1500 kDa (kilodaltons), small enough to penetrate dermis layers but large enough to maintain biological activity. Korean clinics typically use concentrations of 5.625mg PDRN per 2ml vial, standardized across approved Rejuran products. Treatment involves multiple intradermal injections using very fine needles (30-32 gauge) in a grid pattern across targeted areas.
Clinical outcomes become visible gradually as cellular regeneration occurs. Patients typically notice initial improvements in skin texture within 2-3 weeks, with optimal results appearing 4-6 weeks post-treatment. The regenerative effects continue for 3-4 months as new collagen matures and skin remodeling progresses.
Types of Rejuran Products Available in Korea
Korean aesthetic medicine offers several Rejuran formulations, each designed for specific skin concerns and treatment areas. Understanding these variations helps international patients select appropriate protocols during consultations.
Rejuran Healer (Classic)
The original formulation remains the most widely used for overall facial rejuvenation. Rejuran Healer contains 2ml of PDRN solution administered through multiple microinjections across the face. Korean dermatologists recommend this version for treating general aging signs, improving skin tone, reducing fine lines, and enhancing skin barrier function. The standard protocol involves 3-4 sessions spaced 2-4 weeks apart. Board-certified clinics in Gangnam typically charge ₩250,000-₩400,000 ($185-$295 USD) per session for Healer treatments.
Rejuran I (Eye Rejuvenation)
Specifically formulated for the delicate periorbital area, Rejuran I features a lower viscosity and finer PDRN particles optimized for under-eye hollows, dark circles, and crow’s feet. The 1ml syringe contains modified PDRN suitable for thin eye-area skin. Korean ophthalmologic dermatologists developed this variant to address the unique challenges of periorbital aging. Treatment requires precise injection techniques taught in Korean aesthetic medicine programs accredited by the Korean Association of Medical Aesthetics (KAMS). Pricing ranges ₩200,000-₩350,000 ($150-$260 USD) per session.
Rejuran S (Scar Treatment)
Rejuran S targets acne scars, surgical scars, and localized skin depressions. This high-concentration formula delivers focused PDRN doses directly into scar tissue to stimulate collagen remodeling. Korean clinics often combine Rejuran S with subcision or fractional laser treatments for enhanced results. The treatment uses a thicker needle and deeper injection technique compared to Healer. Patients typically need 2-3 sessions with 4-6 week intervals. Cost per session averages ₩150,000-₩300,000 ($110-$220 USD) depending on treatment area size.
Rejuran HB (High Concentration Booster)
The newest addition to the Rejuran line contains double the PDRN concentration of classic Healer. HB targets patients with advanced aging signs or those seeking more dramatic rejuvenation results. Korean aesthetic physicians reserve this formulation for mature skin (40+ years) or patients with significant photodamage. Treatment protocols typically involve 2-3 sessions rather than the standard 4-session course. Premium Seoul clinics charge ₩400,000-₩600,000 ($295-$445 USD) per HB session.
Rejuran Tone-Up Booster
This variant combines PDRN with glutathione and tranexamic acid for brightening effects alongside regeneration. Korean dermatologists developed this formulation specifically for Asian skin types prone to hyperpigmentation. The treatment addresses both skin quality and tone irregularities simultaneously. It has gained popularity among international patients seeking comprehensive facial rejuvenation. Sessions cost approximately ₩350,000-₩500,000 ($260-$370 USD).
Treatment Process and Clinical Protocols in Korean Clinics
Korean medical aesthetic clinics follow standardized protocols regulated by the Ministry of Health and Welfare (MOHW). Understanding the treatment process helps international patients prepare for their Rejuran sessions.
Initial Consultation and Skin Assessment
Board-certified Korean dermatologists begin with comprehensive skin analysis using specialized diagnostic equipment. VISIA skin analysis systems, standard in premium Gangnam clinics, photograph and map skin concerns including pores, pigmentation, vascular conditions, and texture irregularities. Dermatologists assess skin thickness using ultrasound devices to determine appropriate PDRN concentrations and injection depths. The consultation typically lasts 20-30 minutes and includes medical history review to identify contraindications. Most international clinics in Apgujeong offer consultations in English with medical interpreters when necessary.
Pre-Treatment Preparation
Clinics apply topical anesthetic cream (lidocaine 10-20%) 20-30 minutes before injection. Korean protocols emphasize patient comfort, though Rejuran contains minimal lidocaine within the solution itself. Patients remove makeup and undergo thorough facial cleansing with medical-grade antiseptic solutions. Photographs document baseline skin condition for comparison at follow-up appointments. Clinics following KAMS guidelines verify product authenticity by showing patients unopened, sealed Rejuran vials with proper MFDS certification stamps.
Injection Technique and Administration
Korean dermatologists employ specific injection patterns optimized through years of clinical experience. The standard technique involves multiple intradermal injections spaced 1-1.5cm apart in a grid pattern across treatment areas. Injection depth typically ranges 2-3mm into the dermis using 30-32 gauge needles. For full-face Rejuran Healer, clinicians administer approximately 50-100 injection points. The entire injection process takes 15-20 minutes for facial treatment. Skilled practitioners minimize discomfort through rapid injection technique and proper needle angles. Korean aesthetic physicians receive specialized training in PDRN injection methods through programs certified by the Korean Dermatological Association.
Immediate Post-Treatment Care
Injection sites develop small wheals (raised bumps) immediately after treatment—a normal response indicating proper intradermal placement. Clinics apply cooling masks or ice therapy to reduce swelling and discomfort. LED light therapy (typically red wavelength at 630nm) for 15-20 minutes enhances cellular response and accelerates PDRN absorption. Korean clinics provide detailed aftercare instructions in English for international patients. Mild redness and swelling typically resolve within 24-48 hours. Small bruising may occur at injection points but usually fades within 3-5 days.
Follow-Up Schedule and Maintenance
Standard Rejuran protocols require 3-4 initial sessions spaced 2-4 weeks apart for optimal results. Korean dermatologists schedule follow-up assessments before each subsequent session to monitor progress and adjust treatment parameters. After completing the initial series, maintenance sessions every 6-12 months help sustain results. Progressive improvement continues for 2-3 months after each session as collagen synthesis peaks. Clinics document outcomes through comparative photography at 4-week intervals. International patients can complete multiple sessions during extended Seoul visits or coordinate return trips with clinic scheduling departments.
Expected Results, Benefits, and Realistic Outcomes
Understanding evidence-based outcomes helps international patients set appropriate expectations for Rejuran therapy. Korean clinical data provides extensive documentation of treatment results across diverse patient populations.
Timeline of Visible Improvements
Rejuran produces gradual, natural-looking improvements rather than immediate dramatic changes. Patients notice initial skin texture refinement within 2-3 weeks as cellular turnover accelerates. Hydration levels improve noticeably during this early phase, with skin appearing more luminous and supple. Fine lines begin softening at the 4-6 week mark as new collagen forms. Optimal results emerge 8-12 weeks after completing the initial treatment series. Korean dermatologists emphasize that Rejuran stimulates natural regeneration rather than providing instant correction, making results subtle but long-lasting compared to synthetic fillers.
Documented Clinical Benefits
Research published in the Journal of Cosmetic Dermatology confirms multiple Rejuran benefits validated through Korean clinical trials. Skin elasticity measurements show 15-25% improvement after complete treatment courses. Transepidermal water loss (TEWL) decreases by 20-30%, indicating enhanced skin barrier function. Pore size reduces measurably on sebum output analysis. Korean studies demonstrate particular effectiveness for atrophic acne scars, with 40-60% improvement in scar depth and texture. Skin thickness increases by approximately 8-12% on ultrasound imaging, reflecting genuine dermal regeneration rather than temporary swelling. Related options include /p>
Specific Condition Improvements
Fine lines and wrinkles show moderate improvement, particularly superficial expression lines around eyes and mouth. Deep static wrinkles require combination approaches with other modalities. Skin laxity improves mildly to moderately, with best results in patients under 50 with early-stage sagging. Acne scarring responds well, especially rolling and shallow boxcar scars. Ice pick scars require additional treatments like subcision. Enlarged pores refine gradually as sebaceous regulation improves. Dull, dehydrated skin transforms notably, with patients reporting “glass skin” effects popular in Korean beauty standards. Redness and sensitivity decrease as skin barrier strengthens and inflammation reduces. Read about best dermatologist seoul.
Comparative Advantages Over Alternative Treatments
Rejuran offers distinct benefits compared to other aesthetic procedures available in Korea. Unlike hyaluronic acid fillers, Rejuran actually regenerates skin tissue rather than simply filling volume. Results develop more slowly but last longer—typically 12-18 months versus 6-9 months for standard fillers. Compared to laser resurfacing, Rejuran involves no downtime and poses minimal photodamage risk. PRP (platelet-rich plasma) therapy shares regenerative mechanisms but Rejuran provides standardized PDRN concentrations versus variable growth factor levels in patient-derived PRP. Korean clinics often combine Rejuran with complementary treatments for synergistic effects, creating customized protocols unavailable in most other countries.
Limitations and Realistic Expectations
Rejuran cannot replace surgical interventions for severe aging or provide volumizing effects of traditional fillers. Deep nasolabial folds, significant jowling, or pronounced volume loss require different approaches. Results vary based on individual healing capacity, age, skin condition, and lifestyle factors. Younger patients (20s-30s) typically achieve more dramatic improvements than mature patients (60+). Korean dermatologists conduct thorough consultations to ensure patients understand achievable outcomes for their specific concerns. Combining realistic expectations with proper treatment selection maximizes satisfaction rates. Read about comprehensive board certified dermatologist seoul.
Safety, Side Effects, and Contraindications
Korean medical aesthetic standards maintained by MOHW ensure rigorous safety protocols for Rejuran treatments. Understanding potential risks helps international patients make informed decisions.
Common Temporary Side Effects
Most patients experience mild injection-related reactions that resolve quickly. Small raised wheals at injection sites persist 24-48 hours before absorbing completely. Localized redness affects treatment areas for 1-3 days. Mild swelling, particularly noticeable in under-eye treatments, typically subsides within 2-4 days. Small bruises develop in approximately 20-30% of patients, more common in those taking blood-thinning supplements or medications. Tenderness at injection points lasts 2-3 days. Korean clinics provide arnica cream and detailed post-care instructions to minimize these effects. Temporary bumps occasionally persist up to one week but resolve without intervention.
Rare Adverse Reactions
Serious complications remain extremely rare when performed by qualified practitioners. Allergic reactions to PDRN occur in less than 0.1% of cases due to high biocompatibility of salmon-derived components. Infection risk remains minimal with proper sterile technique, standard in Korean board-certified clinics. Nodule formation occasionally develops if product is injected too deeply or concentrated in one area, though these typically resolve within 2-4 weeks or respond to hyaluronidase if necessary. Vascular complications are virtually impossible with Rejuran’s intradermal injection depth, unlike deeper filler placements. Korean medical literature documents no cases of blindness or skin necrosis associated with proper PDRN injection technique. Read about one Gangnam practice.
Absolute Contraindications
Certain conditions preclude Rejuran treatment entirely. Pregnancy and breastfeeding represent absolute contraindications due to insufficient safety data, though no evidence suggests harm. Active skin infections, including herpes outbreaks, require treatment postponement until resolution. Known fish or seafood allergies warrant extreme caution, though salmon DNA processing removes allergenic proteins. Korean dermatologists conduct patch testing for patients with severe allergic histories. Autoimmune conditions affecting skin (lupus, scleroderma) require individual assessment and typically preclude treatment. Active cancer treatment contraindicates elective aesthetic procedures. Patients on anticoagulation therapy face higher bruising risk but can proceed with physician approval.
Relative Contraindications Requiring Assessment
Several conditions require careful evaluation before treatment. Active acne breakouts in treatment areas may warrant postponement, though Rejuran can aid acne scar healing once inflammation resolves. Keloid tendency requires cautious approach, as injection trauma could theoretically trigger keloid formation, though Korean clinical experience shows minimal risk with proper technique. Patients taking isotretinoin should wait 6 months after discontinuation before Rejuran treatment. Recent facial surgery (within 3 months) requires surgeon clearance. Immunosuppressive medications require individual risk-benefit analysis. Korean clinics conduct thorough medical screening to identify these factors during consultations.
Quality and Safety Standards in Korea
Korea maintains strict pharmaceutical and medical device regulations through MFDS oversight. Authentic Rejuran products display holographic security labels and batch traceability codes. Board-certified dermatologists or plastic surgeons must administer injectable treatments—Korean law prohibits non-physician injection. Clinics accredited by KAMS undergo regular safety audits and maintain sterile procedure rooms. International patients should verify practitioner credentials and clinic accreditation through the Korean Medical Tourism Association before booking treatments. Premium clinics in Gangnam and Apgujeong districts typically exceed minimum safety standards and maintain comprehensive liability insurance.
