Rejuran is one of Korea’s most popular skin treatments, often called the “salmon DNA skin booster.” It is known for improving skin quality, texture, and overall health from within, rather than simply adding volume or reducing wrinkles.



Here’s a complete guide to what Rejuran is, how it works, and what results you can expect.

🌍 1. What Is Rejuran (Salmon DNA Treatment)?

Rejuran is an injectable treatment made from polynucleotides (PN) derived from purified salmon DNA.

• Stimulates skin regeneration and healing
• Boosts collagen production and elasticity
• Repairs damaged skin at a cellular level

Unlike Botox or fillers:

• It does NOT add volume
• It focuses on improving skin quality and strength

✔ Think of it as skin repair from the inside

💎 2. Why Salmon DNA?

Salmon DNA is used because it is:

• Highly compatible with human skin
• Low risk of allergic reactions
• Rich in regenerative components (PN)

This makes it ideal for safe and effective skin restoration.

💰 3. Cost of Rejuran in Korea

Korea offers a wide price range depending on clinic and treatment method.

• Full face (standard range)
→ ₩600,000 – ₩1,500,000

• Lower-cost events / partial areas
→ ₩200,000 – ₩400,000

✔ Price depends on:
• Amount used (cc)
• Injection technique
• Clinic expertise

🔬 4. How the Treatment Works

The procedure is relatively straightforward:

1. Skin consultation and analysis
2. Application of numbing cream (20–30 minutes)
3. Micro-injections across the face
4. Soothing care (mask or LED treatment)

• Total time: 30–60 minutes
• Technique: multiple small injections across targeted areas

✨ 5. What Results Can You Expect?

Rejuran focuses on gradual and natural improvement.

• Smoother skin texture
• Reduced pore size
• Improved elasticity
• Brighter, healthier skin tone
• Improvement in fine lines and acne scars

✔ Initial glow: 1–2 weeks
✔ Full results: 4–8 weeks
✔ Duration: 6–12 months

🧴 6. Who Is It Best For?

Rejuran is ideal for:

• Dull or dehydrated skin
• Early signs of aging
• Acne scars or damaged skin
• Enlarged pores and uneven texture

✔ Suitable for both preventive care and skin repair

💉 7. How Many Sessions Do You Need?

For optimal results:

• Recommended: 3–4 sessions
• Interval: every 2–4 weeks

After the initial series, maintenance treatments are typically done every few months.

⚠️ 8. Pain & Downtime

Rejuran can be slightly more uncomfortable than other skin boosters.

• Mild pain during injections (reduced with numbing cream)
• Small bumps on the skin for 1–2 days
• Redness or swelling may last 24–48 hours

✔ Downtime is short but noticeable temporarily

💡 9. Why Rejuran Is So Popular in Korea

Korean dermatology focuses on skin quality and long-term improvement.

• Targets underlying skin damage
• Works well with other treatments (laser, Botox, fillers)
• Helps achieve the popular “glass skin” look

Rejuran is often considered a core treatment for healthy, glowing skin.

💡 Final Thoughts: Is Rejuran Worth It?

Rejuran stands out because it:

• Repairs and regenerates skin rather than masking issues
• Provides long-term improvement
• Delivers natural, healthy-looking results

If your goal is to improve overall skin condition—not just quick cosmetic fixes—Rejuran is one of the most effective treatments available in Korea.
