Product Overview

What is Rejuran I?

Rejuran I is the eye-zone member of the Rejuran range — a more fluid form of the polynucleotide (PN) booster, formulated for the thin, delicate skin around the eyes. Containing salmon-derived PN, it is micro-injected into the periocular area to reduce the appearance of fine lines and crow’s feet, support elasticity and improve under-eye texture and dark circles.

Rejuran I uses the same salmon-derived PN as the Rejuran range but in a more fluid texture, so it can be placed safely in thin periocular skin without lumps or bumps. PN works at the cellular level to stimulate fibroblasts and collagen, addressing fine lines, elasticity and the tired, crepey look of the under-eye area.

Composition

Rejuran I Key Ingredients

Regeneration core

POLYNUCLEOTIDE

Salmon-derived PN
Salmon-derived polynucleotide.

PN is a salmon-DNA fragment, highly biocompatible with human skin, that stimulates fibroblasts and collagen production to repair and strengthen the dermis.

Placement

FLUID FORMULATION

Eye-zone texture
More fluid than standard Rejuran.

The lighter, more fluid form is designed for the thin periocular skin, allowing safe placement without lumps or bumps in the delicate eye area.

Outcome

SKIN-QUALITY SUPPORT

Improves periocular texture and resilience.

Over a treatment course it supports hydration, elasticity and texture around the eyes, helping reduce the appearance of fine lines and dark circles.

Important Safety Information

Read Before Clinical Use

Rejuran I is for licensed practitioners only. The periocular area is delicate and vascular, so injector experience and aseptic technique are essential. Expected reactions include redness, mild swelling, tenderness and small papules at injection points that usually settle within 1–5 days. Screen patients for fish/seafood allergy. Do not treat over active infection or inflammation, and avoid in pregnancy and breastfeeding.

    As someone who does skin boosters often, this eye version is a major step up. It flows much better than filler if you want skin quality improvement rather than just volume. The PN tech really helps with that crepey skin texture under the eyes.
