Rejuran Healer, Rejuran HB and Rejuran I are all PharmaResearch polynucleotide (PN) skin boosters, but they differ in formulation and intended area. Healer is the PN-only option for general face and neck skin quality, HB adds hyaluronic acid (HA) for hydration, and Rejuran I is a lower-viscosity version designed for the thin periorbital skin.
Key Takeaways
- Healer = PN-focused, general face and neck; HB = PN plus HA for hydration; I = low-viscosity PN for the eye area.
- Viscosity and injection area, not brand name alone, should drive product choice.
- Third-party sources disagree on some concentrations, so verify composition on the product label and documentation.
- Evidence suggests polynucleotides are non-inferior to HA boosters in small trials, not clearly superior.
- Regulatory status differs by country and must be verified before importing or using.
What Is the Difference Between Rejuran Healer, HB and I?
The three products share the same PN technology from PharmaResearch Co., Ltd., but the formulation changes according to the target area and the clinical goal. The table summarizes how clinic and distributor sources describe them.
| Type | Key composition | Positioning | Typical area |
|---|---|---|---|
| Rejuran Healer | Salmon-derived PN; sold as 2 x 2 ml | Anti-ageing, skin rejuvenation and healing | Face and neck |
| Rejuran HB | PN 1% + HA 1%; 1 ml | Hydration and repair of dehydrated or dull skin | Dehydrated facial areas |
| Rejuran I | PN 1% in a low-viscosity solution; 1 ml | Fine lines, crow's feet, dark-circle appearance | Periorbital area |
Sources are not fully consistent: one clinic guide lists Healer at 2% PN, while another page gives no concentration at all. For that reason this article does not rely on a single Healer concentration figure; confirm it against the packaging insert. Product details are available on the pages for Rejuran Healer, Rejuran HB and Rejuran I (Eye).
When Is Rejuran Healer the Right Choice?
Healer is generally positioned as the standard option for overall skin quality across the face and neck. Clinic sources describe it as having medium viscosity and list indications such as skin ageing, texture, pore appearance and general tone.
It contains PN as the active substance without added HA in most descriptions. Practitioners who prefer to separate the regenerative effect from hydration effects, or who combine boosters in a staged protocol, often start from this baseline. Our earlier article on how long Rejuran Healer lasts reviews what studies show about duration.
When Does Rejuran HB Make More Sense?
HB makes more sense when dehydration and dullness are the main concern, because the formula pairs PN with HA. "HB" is described as a hydration booster, and sources recommend it for dehydrated areas and skin stressed by UV exposure or inappropriate cosmetic procedures.
The PN-plus-HA combination follows the same logic discussed in our guide to skin boosters versus dermal fillers. One distributor guide also notes that HB is the only Rejuran type that includes a local anesthetic; confirm this against the label for your market, since formulations can vary by region.
Why Is Rejuran I Made for the Eye Area?
Rejuran I uses a thinner, less viscous solution so it can be placed in the delicate periorbital skin, which is among the thinnest on the face. Clinic sources describe its use for crow's feet, fine lines, elasticity and the appearance of dark circles.
Lower viscosity is the practical point: thicker products are harder to place evenly in thin skin. Technique, depth and needle selection remain the practitioner's responsibility, and periorbital injections carry their own risk profile. Results vary between patients.
What Does the Evidence Say About Polynucleotides vs HA?
Evidence is promising but limited. A 2025 clinical overview from Acibadem International reports that small randomized split-face trials, often 20 to 60 participants followed for 12 to 24 weeks, generally find polynucleotides non-inferior to HA boosters, with few showing clear superiority, and it rates the PN evidence as low to moderate certainty.
That overview also notes that the ideal treatment schedule has not been established by comparative trials, and that short studies cannot prove long-term safety. Common effects include temporary bumps, redness, swelling and pinpoint bruising; rare serious risks include hypersensitivity, infection, nodules and vascular injury.

What Should Distributors and Clinics Check Before Buying?
Check composition, pack size, storage, batch documentation and the regulatory status in your destination market. Regulatory status is not uniform: the same overview states that polynucleotide injectables have been approved in South Korea since 2014, that several products carry CE marking (which is not a cosmetic-efficacy evaluation), and that as of mid-2025 no injectable PN product was FDA-approved or cleared for cosmetic use.
- Match each pack size to your volume: Healer is supplied as 2 x 2 ml, HB and I as 1 ml syringes according to the supplier listings.
- Confirm storage requirements and keep a documented cold or controlled-temperature chain.
- Request authenticity and batch documents; see our supplier documents checklist.
- Confirm that import and professional use are permitted locally.
Frequently Asked Questions
What is the main difference between Rejuran Healer and Rejuran HB?
Rejuran Healer is a PN-only formulation intended for general face and neck skin quality, while Rejuran HB combines polynucleotide with hyaluronic acid, positioned for dehydrated or dull skin. Published sources differ on some concentrations, so practitioners should always confirm composition on the label of the batch they purchase.
Is Rejuran I only for the under-eye area?
Rejuran I is described by the manufacturer line and clinic sources as a lower-viscosity PN product designed for the periorbital area, including crow's feet and fine lines. Product positioning is periorbital, but the injection site, technique and suitability remain the decision of the treating practitioner under local regulations.
Can clinics stock all three Rejuran types?
Many clinics stock more than one type because the indications differ: general face, hydration-focused, and periorbital. Stocking decisions depend on patient mix, turnover and cold-chain capacity. A distributor can supply documentation and pack-size details so clinics can plan inventory before ordering.
Is polynucleotide better than hyaluronic acid?
Current evidence does not show clear superiority. A 2025 clinical overview reports that small randomized split-face trials generally find polynucleotides non-inferior to hyaluronic acid boosters, with few reporting clear superiority, and long-term data remain limited. Choice should rest on patient needs, practitioner judgment and product labeling.
Are Rejuran products FDA-approved?
According to a mid-2025 clinical overview, no injectable polynucleotide product has been approved or cleared by the FDA for cosmetic use. The same source states polynucleotide injectables have been approved in South Korea since 2014 and several carry CE marking. Distributors should verify status per destination country.
Conclusion
Choosing between Healer, HB and I comes down to target area, viscosity and whether added HA is wanted. Clinics and distributors comparing the line can request specifications, documentation and wholesale terms through our inquiry page.
