What is Rejuran (Salmon DNA) treatment in Korea?
Rejuran is one of the most talked-about skin regeneration treatments in Korea, often called the “salmon DNA treatment.” Many patients ask—what exactly is Rejuran and how does it work?
Below is a clear, SEO-friendly explanation.
What Is Rejuran (Salmon DNA) Treatment?
Rejuran is a
skin booster injection that uses
PDRN (polydeoxyribonucleotide)—a purified DNA fragment derived from salmon.

dermis (skin layer)

salmon DNA similar to human DNA
• Works to
repair and regenerate skin from within

Rejuran = skin healing & regeneration injection
How Rejuran Works (Mechanism)
Unlike fillers or Botox, Rejuran focuses on
cell-level repair.
What it does:
• Stimulates
fibroblasts → increases collagen & elastin
• Repairs
damaged skin cells and barrier
• Reduces
inflammation and improves healing
👉 It doesn’t add volume—it restores skin health.
What Skin Problems It Treats
Rejuran is widely used in Korea for overall
skin quality improvement.
Common uses:
•
Fine lines and wrinkles
•
Acne scars and damaged skin
•
Enlarged pores and rough texture
•
Dull skin and loss of elasticity
👉 It’s a “foundation treatment” for healthier skin.
Results: Natural and Gradual Improvement
Rejuran works differently from instant treatments.
What to expect:
• Gradual improvement over
2–4 weeks
• Better skin texture, elasticity, and hydration
• More
natural, long-term results
👉 It’s often called a “slow aging” treatment.
Is Rejuran a Filler? (Important Difference)
Many people confuse Rejuran with fillers—but they are different.
•
Rejuran → repairs and regenerates skin
•
Fillers → add volume and shape
👉 Rejuran improves skin quality, not facial volume.
Treatment Process (What Happens During Procedure)
Typical session:
• Numbing cream applied (20–30 min)
• Multiple
micro-injections across the face
• Treatment time: ~15–30 minutes
• Small bumps (like mosquito bites) for 1–2 days
How Many Sessions Are Needed?
Typical plan:
•
3–4 sessions spaced 2–3 weeks apart
• Maintenance every
3–6 months
👉 Results build over time.
Why Rejuran Is So Popular in Korea
Korean dermatology focuses on skin quality, not just appearance.
Reasons for popularity:
• Works at
cellular level, not just surface
• Safe for
sensitive and Asian skin types
• Fits the trend of
natural, regenerative treatments
• Often combined with lasers or boosters
Final Thoughts
Rejuran (salmon DNA treatment) is a
regenerative skin booster designed to
heal, repair, and strengthen the skin from within.
•
Not a filler → no volume change
•
Focus = skin quality, texture, and long-term health
• Best for patients who want
natural, gradual improvement
If your goal is healthier, stronger skin rather than dramatic change, Rejuran is one of the most effective treatments in Korean dermatology.
