Overview
Rejuran (I/S) refers to the targeted variants of PharmaResearch's Rejuran polynucleotide range: Rejuran I for the delicate under-eye area and Rejuran S for scar-focused treatment. Both are built on the same salmon-derived PN active but tuned in viscosity and concentration for their respective indications. They extend the Rejuran line beyond general facial rejuvenation into region- and concern-specific care.
How it works
As with the wider Rejuran range, salmon polynucleotides support tissue repair and fibroblast activity, driving regeneration of collagen and extracellular matrix. Rejuran I uses a lower-viscosity formulation to sit smoothly in thin periorbital skin, while Rejuran S is more concentrated and viscous to support remodelling in scarred or texturally damaged skin.
Indications
- Under-eye fine lines and dark-circle-associated skin quality (Rejuran I)
- Acne and textural scarring (Rejuran S)
- Localised skin regeneration
- Skin elasticity and firmness
- Skin texture refinement
Key features
- Two targeted variants: I (eye) and S (scar)
- Salmon-derived polynucleotide active
- Viscosity/concentration tuned per indication
- 1 mL syringe format
- Manufactured by PharmaResearch (South Korea)
Benefits
- Indication-specific SKUs broaden the Rejuran menu
- Under-eye variant addresses a high-demand concern
- Scar variant opens acne-scar treatment revenue
- Same trusted PN platform as the flagship line
- Supports course-based, repeat-visit protocols
Composition
Polynucleotide (PN) from salmon DNA; Rejuran I is a lower-viscosity 1 mL formulation, Rejuran S a higher-concentration, more viscous 1 mL formulation.
Usage & handling
Injected by fine micro-injection into the target region, typically as a multi-session course spaced around 3-4 weeks apart. Store per the manufacturer's instructions in cool, dry conditions away from direct sunlight; do not freeze.
