Salmon DNA (Rejuran): Why It’s So Good for Your Skin

In the world of advanced skin rejuvenation, one treatment is making waves for its natural, regenerative approach — Rejuran, also known as PN (polynucleotide) therapy or Salmon DNA treatment. But what exactly is it, and why is it so good for your skin?

What Is Rejuran?

Rejuran is an injectable skin treatment derived from polynucleotides (PN) — fragments of DNA extracted from salmon sperm cells. Don’t let that scare you! Salmon DNA is highly biocompatible with human skin, meaning your body easily accepts it without triggering an immune reaction.

This treatment originates from South Korea and has become a go-to for improving skin quality, texture, and elasticity in a natural, restorative way.

Why Is Salmon DNA Good for Your Skin?

Here’s why Rejuran is being called a skin healer:

1. Stimulates Skin Repair

Salmon DNA helps restore damaged skin by stimulating your skin’s own fibroblasts — the cells responsible for producing collagen, elastin, and hyaluronic acid. This means stronger, plumper, healthier skin from the inside out.

2. Reduces Inflammation

PN has powerful anti-inflammatory properties. It calms irritated skin, reduces redness, and helps heal conditions like acne scars or sensitive, compromised skin.

3. Improves Skin Elasticity and Texture

By increasing collagen synthesis, Rejuran helps improve skin firmness, smooths fine lines, and enhances overall skin texture, especially in delicate areas like under the eyes, neck, and cheeks.

4. Enhances Skin Hydration

While not a filler, Rejuran improves the skin’s moisture retention over time, giving it that dewy, youthful glow without adding volume.

5. Natural and Long-Lasting

Because it works with your body’s healing process rather than temporarily masking imperfections, the effects of Rejuran are subtle but long-lasting — typically improving over 4 to 6 weeks after treatment.

What Skin Concerns Does Rejuran Treat?

• Fine lines and wrinkles
• Skin laxity
• Acne scars
• Enlarged pores
• Sun-damaged or aging skin
• Dull, uneven skin tone
• Thin or crepey skin (especially under eyes or neck)

What to Expect During Treatment

Rejuran is delivered via microinjections into the dermal layer of the skin. Most people require a series of 3 to 4 sessions spaced 3–4 weeks apart, followed by maintenance treatments every 6–12 months. There is minimal downtime, with some mild redness or small bumps immediately after treatment that subside within 24–48 hours.

Final Thoughts

If you're looking for a natural, regenerative skin treatment that boosts your skin’s own ability to repair and renew, Rejuran might be exactly what your skin needs. It’s not about plumping or freezing — it’s about healing, reviving, and rebuilding your skin at a cellular level.
