What Is Rejuran? Eye vs. Scar

If you’ve been noticing how often Rejuran comes up in skin treatment conversations, you’re not alone. It’s one of the most popular skin healing injectable treatments right now. But did you know there are different types, each designed with a specific purpose? Two of the most commonly asked about formulas are Rejuran Eye and Rejuran Scar.

Here’s your simple breakdown.

First, What Is Rejuran?

Rejuran is an injectable treatment made from polynucleotides (PN), long chains of DNA fragments derived from salmon. Why salmon? The molecular structure is incredibly biocompatible with human skin, meaning your skin recognises it and responds beautifully.

What Rejuran does:

• Boosts natural collagen production

• Repairs damaged skin cells

• Improves elasticity

• Strengthens the skin barrier

• Reduces inflammation

It’s essentially like giving your skin a biologically active “reset.”

Rejuran Eye

Rejuran Eye is a specially formulated version designed for the very delicate under-eye area. This skin is thinner, more fragile, and often the first place to show ageing.

What it treats:

• Fine lines and crepiness under the eyes

• Tired or dull under eye skin

• Mild volume loss or “hollowness”

• Texture issues

Why it works well under the eyes:

• The solution is lighter and softer, so it spreads evenly without causing puffiness.

• It encourages collagen and elastin production to thicken and strengthen thin tissue.

• It improves hydration and overall skin quality.

Treatment notes:

• Usually done in a series (e.g., 3–4 sessions spaced 3–4 weeks apart).

• Minimal downtime, some small bumps immediately after are normal and settle within a few hours.

Rejuran Scar

Rejuran Scar is a more concentrated, thicker formula designed specifically for acne scarring and deeper textural issues.

What it treats:

• Acne scars (rolling, boxcar, ice-pick when combined with other modalities)

• Surgical scars

• Stretch marks

• Areas of uneven texture

Why it works well for scarring:

• It delivers a stronger collagen-stimulating effect to remodel damaged tissue.

• Helps “fill in” and repair depressed scars over time.

• Reduces redness and inflammation around old scarring.

Treatment notes:

• Often combined with other treatments like skin needling or subcision for best results.

• Multiple sessions are recommended depending on the severity of the scars.
