Rejuran I is the eye-area polynucleotide (PN) product from PharmaResearch, supplied as a single 1 mL prefilled syringe. Its PN is purified from salmon DNA using the company’s DOT™ technology, and it is formulated at a low viscosity so it can be placed superficially and evenly in the thin skin around the eyes. Clinics select it for fine crepey periorbital lines and thin, lax eye-area skin rather than for adding volume. It is intended for administration by qualified medical professionals.
What is Rejuran I?
Rejuran I is the eye-area member of PharmaResearch’s Rejuran range of injectable polynucleotide (PN) products, purified from salmon DNA with the company’s patented DOT™ (DNA Optimizing Technology) process. It is supplied as a single ready-to-use 1 mL prefilled syringe.
What sets it apart within the range is its low viscosity. The skin around the eyes is the thinnest on the face, and a thinner fluid is easier to place superficially and evenly there — which is why clinics keep a dedicated periorbital product rather than using a denser formulation off-area.
How is Rejuran I different from the other Rejuran products?
All four are polynucleotide products from the same manufacturer, built for different jobs. Rejuran I is the one formulated for the delicate periorbital skin.
| Rejuran Healer | PN only · 2 × 2 mL · broad, full-face skin quality |
|---|---|
| Rejuran I | Low-viscosity PN · 1 × 1 mL · the delicate eye area |
| Rejuran S | Long-chain, high-viscosity PN · 1 × 1 mL · localised scars and texture |
| Rejuran HB | PN + non-crosslinked HA, with lidocaine · 1 × 1 mL · regeneration plus immediate hydration |
What is Rejuran I used for?
It is commonly selected for the periorbital area — fine crepey lines, thinning and loss of resilience in the skin under and around the eyes. Because it is a regenerative skin product rather than a hyaluronic acid filler, it is positioned to support the skin’s own repair rather than to add contour or volume, and it is not a treatment for under-eye hollowing. Indications, injection depth and technique are product-specific per the manufacturer’s labeling and are decided by the treating clinician.
Commonly selected for
- Fine, crepey lines around and beneath the eyes
- Thin, lax periorbital skin needing skin-quality rather than volume treatment
- Treatment plans pairing eye-area work with a full-face skin booster
- Practitioners who want a low-viscosity PN for precise superficial placement
Treatment is typically delivered as a short course of sessions spaced a few weeks apart, per the practitioner’s protocol. The periorbital area demands precise superficial technique, and suitability is always assessed by the treating clinician.

Frequently asked questions
What is Rejuran I used for?
It is commonly selected for the periorbital area — fine crepey lines and thin, lax skin around and beneath the eyes. Indications and technique are product-specific per the manufacturer’s labeling and are decided by the treating clinician.
How is Rejuran I different from Rejuran Healer?
Both are polynucleotide products from PharmaResearch. Healer comes as two 2 mL syringes for broad full-face skin quality; Rejuran I is a low-viscosity 1 mL syringe formulated for the much thinner skin of the eye area, where a thinner fluid is easier to place superficially and evenly.
Is Rejuran I a filler for under-eye hollows?
No. It is a polynucleotide skin product intended to support the skin’s own repair, not a hyaluronic acid filler designed to add contour or volume, so it is not a treatment for under-eye hollowing.
How is it supplied?
As a single ready-to-use 1 mL prefilled syringe.
How should Rejuran I be stored and handled?
Store and handle strictly according to PharmaResearch’s instructions for use, and administer only within its intended professional setting.
