Exosomes vs Rejuran in Korea reflects the rapidly evolving landscape of Korean aesthetic medicine, where the pursuit of “Glass Skin” (a translucent, luminous, pore-less complexion) is no longer just about topical serums, but about cellular reprogramming.
For years, Rejuran Healer (Salmon DNA) reigned supreme as the gold standard for skin repair. However, a new contender has emerged with explosive popularity: Exosome Therapy. Patients visiting our clinic often ask: “I want the best skin of my life. Should I stick with the proven Rejuran, or switch to the advanced biotechnology of Exosomes?”
At View Plastic Surgery, we believe in informed decisions. This comprehensive guide compares Korea’s two most powerful non-invasive treatments to help you achieve your 2026 skin goals.
Exosomes: The 2026 Cell-Signaling Revolution
What are Exosomes?
Exosomes are not cells; they are the avatars of cells. Scientifically, they are nanosized extracellular vesicles (30-150 nm) secreted by stem cells. Think of them as microscopic couriers carrying a precious cargo of mRNA, miRNA, growth factors, cytokines, and proteins. Unlike traditional cosmetics that sit on the skin’s surface, exosomes are designed to penetrate and deliver instructions to your existing skin cells, telling them to regenerate, repair, and behave like younger cells.
The Mechanism: The Paracrine Effect
The magic of exosome therapy lies in the “Paracrine Effect.” When applied to the skin (often via MTS or microneedling to bypass the skin barrier), exosomes dock into damaged cells and release their payload. This triggers an immediate anti-inflammatory response and kickstarts the production of collagen and elastin from within. This is why exosomes are often referred to as “4th Generation Skin Boosters.”
Key Benefits for 2026
- Anti-Inflammation Powerhouse: Exosomes are superior in calming sensitive, acne-prone, or rosacea-affected skin.
- Texture and Pore Reduction: By signaling fibroblast activity, they significantly refine skin texture and shrink enlarged pores.
- Barrier Restoration: They repair the lipid barrier, making them ideal for skin damaged by harsh lasers or environmental pollution.
Rejuran Healer : The Regenerative King
What is Rejuran?
Rejuran Healer is formulated from Polynucleotides (PN), which are DNA fragments derived from wild salmon. Why salmon? The DNA base composition of salmon is strikingly similar to human DNA, making it highly biocompatible with minimal risk of immune reaction. It is arguably the most famous skin booster in South Korea over the last five years.
The Mechanism: ECM Restoration
Rejuran works by mechanically and biologically scaffolding the skin. When injected into the dermis, the long chains of PN create a 3D structure that supports the Extracellular Matrix (ECM). It acts as a salvage pathway for DNA synthesis, essentially providing the “building blocks” your skin needs to repair itself. Unlike hyaluronic acid fillers that only provide volume/hydration, Rejuran actually increases the thickness and density of the dermis.
Why It Remains a Top Choice
- Dermal Thickness: It is clinically proven to thicken the dermis, reducing the appearance of fine lines and increasing elasticity.
- Oil-Moisture Balance: Rejuran is exceptional at normalizing sebum production, making it great for both dry and oily skin types.
- Slow-Aging: It provides a cumulative preventative effect against aging.
Head-to-Head Comparison : Exosomes vs. Rejuran
Choosing between these two depends largely on your pain tolerance, downtime preference, and specific skin issues. Below is a detailed clinical comparison.
| Feature | Exosome Therapy (The 2026 Trend) | Rejuran Healer (The Classic) |
|---|---|---|
| Primary Ingredient | Stem Cell-derived Exosomes (mRNA, Cytokines) | Polynucleotide (PN) from Salmon DNA |
| Primary Goal | Cell signaling, Anti-inflammation, Glow | Structural repair, Dermal thickening, Elasticity |
| Pain Level | Low to Moderate (Applied via MTS/Microneedling) | High (Direct Injection). Note: Rejuran HB Plus includes Lidocaine to reduce pain. |
| Downtime | 1-2 days of redness (from microneedling) | 3-5 days of “Embossing” (bumps at injection sites) |
| Best Candidate | Acne scars, redness, dullness, sensitive skin | Thinning skin, fine lines, loss of elasticity |
Which Should You Choose for the 2026 Glass Glow?
The choice is not always binary. In fact, at View Plastic Surgery, we often utilize combination protocols depending on the depth of the skin issue.
Choose Exosomes IF:
- You have inflammatory issues: If you suffer from active acne, acne scarring, or rosacea, the anti-inflammatory properties of exosomes are superior.
- You hate needles: Since exosomes are legally classified as cosmetics in many jurisdictions (including Korea), they are applied topically after creating micro-channels (MTS or Laser), avoiding the deep injections required for Rejuran.
- You want a faster “Glow”: Patients often report a visible brightness within 3-5 days post-treatment.
If you are interested in exploring the different types of boosters available, please review our comprehensive skin booster programs to see which aligns with your needs.
Choose Rejuran IF:
- You are concerned about aging: If your skin feels thin, crepey, or lacks elasticity, the structural repair of PN is unmatched.
- You want long-term health: Rejuran builds the foundation. While the “glow” takes longer (2-3 weeks) to appear compared to Exosomes, the thickening effect lasts longer.
- You have fine lines around eyes/neck: Rejuran I (Eye) and Rejuran S (Scars) are specialized versions that target these difficult areas effectively.
Still unsure? We highly recommend a professional diagnosis. You can schedule your consultation with our dermatology specialists to analyze your skin depth and barrier health.
Conclusion: The View Plastic Surgery Verdict
For 2026, Exosomes are indeed the breakout star for achieving that high-gloss, even-toned “glass skin” look with minimal downtime. However, Rejuran remains the champion of deep dermal repair. Ideally, a holistic anti-aging plan might involve Rejuran to build the structure and Exosomes to polish the surface.

FAQ
Is Rejuran or Exosome better for acne scars?
For deep, rolling acne scars, Rejuran S (a thicker viscosity PN) is often better for physically filling the indentation. However, for general texture, redness, and post-acne pigmentation, Exosomes are superior due to their anti-inflammatory cell signaling.
Does Exosome therapy hurt?
Generally, no. Exosomes are applied topically after Microneedling (MTS) or fractional laser. The pain comes from the microneedling process, which is mild and managed with numbing cream. It is significantly less painful than Rejuran injections.
Can I do Rejuran and Exosomes together?
Yes, this is a popular “Synergy” treatment in Korea. We often inject Rejuran first for deep repair and finish with Exosomes via MTS to soothe the skin and accelerate surface healing.
How long does Rejuran embossing last?
The “embossing” (raised bumps at injection points) typically lasts 24 to 72 hours. In patients with slower lymphatic drainage, it may persist slightly longer but can be covered with makeup after 24 hours.
What is the recommended frequency for Exosome therapy?
For the best “glass skin” results, we recommend a course of 3 to 5 sessions spaced 2 weeks apart. Maintenance can be done once every 3 to 6 months.
Is Rejuran HB Plus less painful?
Yes. Rejuran HB Plus contains Hyaluronic Acid (for immediate hydration) and Lidocaine (an anesthetic), making the injection process about 50% less painful than the classic Rejuran Healer.
Are Exosomes safe?
Yes, provided they are high-quality, purified exosomes (usually from plant or human adipose stem cells) produced in a sterile lab. View Plastic Surgery only uses KFDA-approved, premium exosome brands.
How soon will I see results?
Exosomes provide a glow and reduced redness within 3-7 days. Rejuran results take longer, usually appearing after 2 weeks as collagen production increases and water balance improves.
Can I combine these with Ultherapy or Thermage?
Absolutely. Energy devices (Ultherapy/Thermage) tighten the deep fascia, while Skin Boosters (Rejuran/Exosomes) improve the superficial skin quality. Doing both yields the best anti-aging results.
Is there downtime for Exosome therapy?
Downtime is minimal. You may look slightly pink (like a mild sunburn) for 12-24 hours due to the microneedling, but this fades quickly compared to Rejuran marks.
