“Korean skin boosters go far beyond hydration — they’re ‘liquid gold’ that rebuilds skin at the cellular level.”
Korea leads the world in skin booster and injectable skin treatments. Korean clinics offer a far wider range of skin boosters than anywhere else — from the iconic Rejuran series to cutting-edge Exosome therapy, RE2O ECM skin booster, and Laetigen collagen boosters. Each has unique benefits tailored to specific skin concerns.
This comprehensive guide breaks down Korea’s most popular skin boosters to help you find the perfect treatment for your skin.
1. Rejuran Series — Korea’s National Skin Booster
Rejuran is Korea’s most iconic skin booster brand. Its core ingredient — polynucleotide (PN/PDRN) derived from salmon DNA — repairs damaged skin cells at the DNA level and stimulates collagen regeneration. Nearly every Korean dermatology clinic carries Rejuran.
Rejuran Healer (Red Box) — Classic Repair
The original Rejuran and Korea’s most widely used skin booster. Moderate PN concentration for skin repair and regeneration. Benefits: Repairs damaged skin barrier, improves texture, thickens dermis, boosts elasticity, minimizes pores. Best for: All skin types, especially thin/sensitive/barrier-damaged skin. 3-4 sessions recommended, 2-4 weeks apart. Reference price: ₩150-300K/session.
Rejuran HB (Black Box) — Deep Hydration
PN formula enhanced with hyaluronic acid (HA) for dual repair + deep hydration. Smoother texture, more comfortable injection. Benefits: All Healer benefits + deep moisture lock, instant glow, improved dryness. Best for: Dry skin, seasonal sensitivity, those wanting immediate radiance. Reference price: ₩200-350K/session.
Rejuran i (White Box) — Eye Area Specialist
Specially developed for the delicate eye area. Smaller PN molecules at refined concentration. Benefits: Reduces dark circles, improves fine lines around eyes, thickens under-eye skin, brightens eye area. Best for: Dark circles, crow’s feet, post-eye surgery recovery. Can be combined with Healer/HB for full-face + eye treatment. Reference price: ₩150-250K/session.
Rejuran S (Blue Box) — Scar Repair
High-concentration PN formula targeting acne scars and atrophic scars. Benefits: Promotes scar tissue remodeling, improves pitted acne scars, enhances skin’s self-repair capacity. Best for: Acne scarring, surgical scars, atrophic scars, enlarged pores. Often combined with laser treatment. Reference price: ₩200-350K/session.
How to Choose Your Rejuran
- Daily maintenance / First-timer → Red Box (Healer)
- Dry skin / Instant glow → Black Box (HB)
- Eye area concerns → White Box (i)
- Acne scar repair → Blue Box (S)
- Best combo → Red/Black full-face + White for eyes + Blue for targeted scars
2. Exosome Therapy — The New Frontier of Regenerative Skincare
Exosomes are the hottest ingredient in Korean dermatology. These nano-sized vesicles secreted by stem cells carry growth factors, mRNA, and proteins that deliver direct “repair signals” to skin cells — more precise and effective than traditional growth factors.
Key benefits: Activates skin self-repair at the cellular signaling level; powerful anti-inflammatory and barrier repair; stimulates new collagen and elastin; improves pigmentation and evens skin tone; accelerates post-procedure recovery. Popular brands: ASCE+, ExoSCRT, Cellthera. Best for: Dull/aging skin, post-procedure recovery, sensitive skin repair. Reference price: ₩300-800K/session.
3. RE2O (리투오) — Human Dermal ECM Skin Booster
RE2O (리투오) is a revolutionary ECM skin booster launched in Korea in 2024. It’s the world’s first injectable product derived from human dermal extracellular matrix (ECM) — delivering real human collagen and elastin directly into your skin.
Core composition: Acellular human allogenic dermis (hADM) microparticles containing 89% collagen + 3% elastin + 7.6% other ECM components + 0.4% hyaluronic acid (GAG). Directly replenishes lost dermal structural components while inducing natural collagen regeneration.
How it differs from traditional boosters: Traditional boosters like Rejuran “stimulate” your skin to produce collagen. RE2O “directly supplies” real human dermal components — more immediate and longer-lasting results.
Benefits: Significant elasticity improvement, pore reduction, fine line smoothing, overall texture upgrade. Results appear gradually over 1-2 weeks, peaking at 2-3 months. Protocol: 3 sessions at 2-3 month intervals initially, then maintenance lasts 12-18 months. Reference price: ₩500-700K/session.
4. Laetigen (레티젠) — 99.9% Pure Collagen Skin Booster
Laetigen (레티젠) is a MFDS-approved (Korean FDA) high-purity collagen injection. Its core ingredient is 99.9% pure Type I collagen — the primary structural protein comprising over 70% of human skin. Laetigen injects collagen identical in structure to your own skin directly into the dermis.
Composition: Type I collagen (99.9% purity) + glycine (stabilizes collagen triple helix). Excellent biocompatibility with minimal rejection risk.
Benefits: Immediate skin firmness and elasticity boost, fine line reduction, pore minimization, improved texture and radiance. Skin feels firmer right after treatment; collagen regeneration peaks at 2-4 weeks. Protocol: Every 4 weeks, 3 sessions per course. Single session lasts 4-6 months; 3+ sessions can last 12+ months. Reference price: ₩300-500K/session.
Laetigen vs RE2O: Laetigen focuses on pure collagen supplementation; RE2O delivers complete ECM matrix (collagen + elastin + more). Both are “direct supply” types with different compositions. Choose based on skin needs or combine them.
5. Other Popular Korean Skin Boosters
NCTF / Filorga: 55 active ingredients (vitamins, amino acids, minerals). Comprehensive nutrition and antioxidation. ₩200-400K. Juvelook: PDLLA collagen stimulator — continued collagen production for 3-6 months. ₩250-500K. Profhilo: Ultra-high concentration HA (64mg/2ml), 5-point injection for bio-remodeling. ₩300-600K.
Who Is It For?
- Dry, dull skin lacking radiance — want deep skin quality improvement
- Enlarged pores, rough texture — seeking baby-smooth skin
- Acne scars, pigmentation — need repair and restoration
- Under-eye fine lines, dark circles — prominent eye area concerns
- Ages 25+ seeking preventive anti-aging maintenance
- Post-laser/thread/surgery — want accelerated recovery
- Needle-phobic but want better skin (try RE2O)

Skin Booster Pricing in Korea (2026)
One of the biggest advantages of getting skin boosters in Korea is the pricing. Korean clinics offer these treatments at a fraction of the cost in the US, Europe, or Southeast Asia — while using the exact same (or newer) products.
| Treatment | Korea (Seoul) | Japan | USA | Singapore |
|---|---|---|---|---|
| Rejuran Healer (1 session) | $150–250 | $300–500 | $400–700 | $350–550 |
| Exosome Therapy (1 session) | $200–400 | $500–800 | $600–1200 | $500–900 |
| RE2O ECM Booster (1 session) | $180–300 | N/A | N/A | $400–600 |
| Laetigen Collagen (1 session) | $150–280 | N/A | N/A | N/A |
| Combo Package (Rejuran + Exosome) | $300–500 | $700–1100 | $900–1500 | $700–1200 |
Prices are approximate 2026 Seoul Gangnam-area references in USD. Many clinics offer package discounts for 3–4 session courses.
What to Expect: Step-by-Step Treatment Process
If you’re coming to Korea for skin booster treatments, here’s exactly what the experience looks like from start to finish:
Before Your Visit
Consultation (online or in-person): A dermatologist reviews your skin concerns — photos, skin type, problem areas, and goals. Many Korean clinics offer free pre-visit consultations via messaging apps. BeautsGo can arrange this for you through WeChat, LINE, or our mini-program.
Pre-treatment prep: Avoid retinoids and strong exfoliants for 3 days before treatment. No alcohol the night before. Stay well-hydrated.
Day of Treatment
Step 1 — Cleansing & skin analysis: The clinic removes all makeup and may use a skin analyzer (like VISIA or similar devices) to map your skin’s condition — hydration, pore size, pigmentation, and elasticity levels. This data helps the doctor customize the injection plan.
Step 2 — Numbing cream application (20–30 min): A topical anesthetic (usually lidocaine-based) is applied. Korean clinics are known for their excellent pain management — many patients report the experience as nearly painless.
Step 3 — Injection (15–30 min): The doctor uses either a manual micro-injection technique (nappage method) or a MTS/stamp device. For Rejuran, micro-injections are placed across the treatment area in a grid pattern. For exosomes, the doctor may combine micro-needling with direct injection. The entire process typically takes 15–30 minutes depending on the treatment area.
Step 4 — LED light therapy & calming mask (10–15 min): Most Korean clinics include a post-treatment LED session and a soothing mask to reduce redness and accelerate healing. This is typically included in the treatment price.
After Treatment: Recovery Timeline
Day 0 (treatment day): Mild redness, possible tiny bumps (especially with Rejuran). No makeup for 6–12 hours. Avoid touching the face.
Day 1–2: Rejuran bumps begin to flatten. Slight swelling possible. You can wear light makeup. Most patients feel comfortable going out.
Day 3–5: All bumps and redness should be gone. Skin starts to feel smoother and more hydrated.
Week 2–3: Collagen stimulation kicks in. Skin texture improvement becomes noticeable — finer pores, smoother surface, improved tone.
Week 4–8: Full results visible. This is when most patients notice the biggest difference in skin quality, elasticity, and glow.
Month 3–6: Effects can last 3–6 months depending on the product and individual metabolism. Maintenance sessions (every 3–6 months) recommended to sustain results.
Side Effects and Safety: What You Need to Know
Korean skin boosters are generally considered very safe when administered by qualified dermatologists. Korea’s strict MFDS (Ministry of Food and Drug Safety) regulations ensure all products used in clinics are properly tested and approved.
Common side effects (normal and temporary): Small injection bumps (Rejuran-specific, resolve in 1–3 days), mild redness and swelling at injection sites (a few hours to 1 day), minor bruising (occasionally, resolves in 3–5 days).
Rare side effects: Allergic reaction (extremely rare — Rejuran’s salmon DNA has very low immunogenicity), infection (risk is negligible at reputable Korean clinics with proper sterilization), uneven results (can occur with inexperienced injectors).
Who should NOT get skin boosters: Pregnant or breastfeeding women, people with active skin infections or open wounds in the treatment area, patients on blood thinners (consult your doctor first), individuals with known allergies to salmon DNA (for Rejuran specifically).
How to Choose the Right Skin Booster for Your Skin
With so many options available in Korea, choosing can be overwhelming. Here’s a decision framework based on your primary skin concern:
If your main concern is aging/wrinkles: Start with Rejuran Healer + Exosome therapy combination. The PN/PDRN repairs existing damage while exosomes supercharge cell regeneration. Add Laetigen if you want collagen-focused results.
If your main concern is dryness/dehydration: Rejuran HB (the hydration specialist) is your best bet. For severe dehydration, combine with RE2O which delivers ECM components deep into the skin.
If your main concern is acne scars: Rejuran S is specifically designed for scar treatment. Combine with exosome therapy for enhanced repair. Multiple sessions (4–6) may be needed for significant scarring.
If your main concern is dark circles/eye area: Rejuran i (eye formula) with its fine needle delivery system is the gold standard. Nothing else targets the delicate under-eye area as precisely.
If you want an all-around glow-up: The most popular Korean “skin glow package” combines Rejuran Healer + Exosome + LED therapy in a single visit. Many clinics offer this as a discounted combo.
If you’re a first-timer: Start with a single Rejuran Healer session. It’s the most proven, most widely used skin booster with the longest safety track record. You can always add other treatments in subsequent sessions.
Frequently Asked Questions
How often should I get skin booster treatments?
For initial treatment, most skin boosters require 3–4 sessions spaced 2–4 weeks apart. Rejuran Healer is typically done every 2–4 weeks for the initial course. Exosome therapy follows a similar schedule. RE2O can be done weekly or bi-weekly. After completing the initial course, maintenance sessions every 3–6 months are recommended to sustain results.
Is the treatment painful? What about downtime?
Korean clinics apply numbing cream for 20–30 minutes before treatment, making the procedure nearly painless. Most patients describe it as mild pinpricks. Rejuran causes small bumps that disappear in 1–3 days. Exosome therapy and RE2O have virtually zero downtime — you can return to normal activities immediately. Light makeup is possible 6–12 hours after treatment.
What is the difference between Rejuran and regular hyaluronic acid skin boosters?
Regular skin boosters like Skinvive or Profhilo mainly use hyaluronic acid (HA) for hydration. Rejuran’s core ingredient — polynucleotide (PN/PDRN) from salmon DNA — goes much deeper: it actually repairs damaged skin cells at the DNA level and stimulates your body’s own collagen production. The results are more fundamental and longer-lasting, though both types can be combined for maximum benefit.
How much do skin boosters cost in Korea compared to other countries?
Skin boosters in Korea are significantly cheaper than in other countries. A single Rejuran Healer session costs $150–250 in Seoul (Gangnam area), compared to $400–700 in the US and $300–500 in Japan. Exosome therapy ranges from $200–400 in Korea versus $600–1200 in the US. Many Korean clinics offer package deals for 3–4 sessions that further reduce the per-session cost.
Can I combine different skin boosters in one visit?
Yes, and Korean clinics are experts at combination protocols. The most popular combo is Rejuran Healer + Exosome therapy in a single session. Another popular combination is Rejuran for the face + Rejuran i for the eye area. Your dermatologist will customize the combination based on your skin analysis results. Combining treatments often provides synergistic results that exceed what any single product can achieve alone.
How long do skin booster results last?
Results vary by product and individual. Rejuran Healer effects typically last 3–6 months after completing a full course. Exosome therapy results can last 4–6 months due to its stem cell regeneration mechanism. RE2O provides immediate hydration that lasts 2–4 weeks per session, with cumulative benefits over a course. Laetigen collagen boosting effects last 3–4 months. Regular maintenance sessions extend and compound the benefits over time.
Is it safe to get skin boosters if I have sensitive or acne-prone skin?
Rejuran is actually excellent for sensitive skin — its PN/PDRN ingredient helps repair the skin barrier, which is often compromised in sensitive skin types. For acne-prone skin, Rejuran S is specifically designed to improve acne scarring. However, active breakouts should be treated first before getting skin boosters. Your Korean dermatologist will assess your skin condition and may recommend a preliminary treatment plan if needed.
What age should I start getting skin boosters?
There’s no strict age requirement, but most Korean dermatologists recommend starting preventive skin booster treatments in your mid-to-late 20s, when collagen production begins to decline. In your 20s, lighter options like RE2O or Rejuran HB are ideal for maintaining hydration. In your 30s and beyond, Rejuran Healer and Exosome therapy become more relevant for anti-aging and collagen stimulation. The earlier you start, the better you can maintain skin quality long-term.
I’m visiting Korea for just a few days — can I get skin boosters?
Absolutely. A single skin booster session takes only 45–60 minutes including numbing time. You can get treated on day 1 and enjoy the rest of your trip with minimal downtime. Many international patients combine a skin booster treatment with sightseeing. If you want a full course, you can do the first session in Korea and discuss follow-up options with your dermatologist — some patients return for subsequent sessions, while others find qualified clinics in their home country to continue the protocol.
