REJURAN®

About REJURAN® Skin Booster — PDRN Regenerative Skincare from South Korea

REJURAN® is a regenerative skincare brand built around purified polynucleotide (PN) and polydeoxyribonucleotide (PDRN) derived from salmon. The professional injectable line is intended for administration by licensed medical professionals and is commonly incorporated into clinical protocols for skin recovery, texture improvement, and overall skin quality. To complement in-clinic work, REJURAN® skincare also spans a homecare range covering a REJURAN® serum, a REJURAN® cream, an overnight serum, a healing essence, a REJURAN® mask, toners, and eye-care products, all designed to extend the benefits of in-clinic treatment between visits [1].

What distinguishes the brand as a skin booster is that both tracks share the same underlying PN/PDRN platform rather than functioning as separate product philosophies stitched together. A patient moving from a REJURAN® Healer treatment series into the homecare range is, in principle, continuing the same biological mechanism at a lower, cosmetic-grade concentration. That continuity is part of what practitioners reference when explaining a REJURAN®-based plan to patients who want to understand why a take-home product was recommended alongside an in-clinic procedure. Clinics that buy Korean dermal fillers as part of a broader formulary frequently add REJURAN® alongside that category, given the shared South Korean origin and overlapping regenerative positioning [4].

Why Practitioners Choose REJURAN® PDRN Technology

REJURAN®’s appeal to practitioners starts with mechanism. Where volumizing fillers add structural support, Rejuran PDRN is built to address overall skin quality and the skin’s own healing capacity, stimulating fibroblast activity and collagen synthesis rather than displacing tissue. Practices that buy dermal fillers for structural correction generally find the two categories answer different patient complaints rather than competing, which is why REJURAN® tends to enter a formulary as an addition rather than a replacement. That distinction makes it a natural fit for practices building comprehensive skin-health protocols around aging, thin, damaged, or post-procedure skin [1].

The second differentiator is structural rather than clinical. REJURAN® operates on a dual track, pairing professional injectables with a personal care range built on the same platform. That lets clinics extend a treatment’s regenerative philosophy into take-home products patients use between visits, supporting both ongoing clinical outcomes and an additional retail revenue stream. Single-track injectable brands generally cannot offer that.

Behind both tracks is PharmaResearch Co., Ltd., a Korean skin care specialist refining technology from South Korea for PDRN and PN applications [4]. The company has built growing adoption beyond its home market, including a rising base of REJURAN® before and after documentation and REJURAN® reviews from the United States. That uptake reflects a broader shift in aesthetic medicine toward innovating skincare with regenerative science, with PN- and PDRN-based products increasingly positioned alongside, rather than against, established volumizing and bioremodeling treatments.

REJURAN® Technology — PDRN, Hydrolyzed DNA, and How REJURAN® Treatment Works

REJURAN® salmon DNA technology is based on purified polynucleotide and polydeoxyribonucleotide, which are hydrolyzed DNA fragments derived from salmon. These nucleotide fragments are processed to support skin repair and regeneration [4]. Clinics that buy polynucleotides for their regenerative menu often add REJURAN® as a core option within that category.

Mechanistically, REJURAN® PDRN works primarily by binding the adenosine A2A receptor, which helps regulate local inflammation, supports vascular endothelial growth factor activity, and creates conditions favorable to tissue healing [3]. It also supplies nucleotide building blocks that encourage fibroblast activity, cell migration, and extracellular matrix production, contributing to improvements in skin quality across a course of REJURAN® treatment [3]. This places the brand in a different mechanistic category from hyaluronic acid fillers, which rely on gel volume and water retention, and from amino-acid-based boosters, which supply raw materials for collagen synthesis without the same receptor-level signaling.

Published research supports the mechanism. A phase III, randomized, double-blind, active-controlled trial comparing a polynucleotide filler with a hyaluronic acid filler in the correction of crow’s feet found PN treatment produced durable improvements in periorbital wrinkles and skin quality, with a safety profile comparable to the HA comparator and only mild, temporary injection-site reactions [2]. Clinics that buy mesotherapy products for microinjection-based delivery often fold REJURAN® into the same protocols, since the administration technique overlaps closely.

REJURAN® Product Range — Injectables, Homecare, and Where to Buy REJURAN® Wholesale

REJURAN® spans two distinct tracks, and the two should never be presented as interchangeable. The injectable line is intended for clinical use by licensed practitioners. REJURAN® cosmetics covers the homecare side, including creams, serums, a REJURAN® overnight serum, a REJURAN® healing essence, a REJURAN® face mask range, a REJURAN® toner, and a tone up booster for daily use. These complement professional treatments rather than replace them, and the homecare line should not be presented as a medical treatment. Healthcare providers who purchase REJURAN® online should source injectable products through authorized channels.

At Medical Spa Rx, we give licensed professionals access to both tracks in one place, with individual-unit and wholesale ordering through a single checkout. Clinics that buy skinboosters as part of a wider regenerative formulary can compare the injectable and homecare lines side by side before they buy REJURAN® online. Practices that buy REJURAN® wholesale on a recurring basis can set up larger purchasing programs to simplify inventory, and shipping arrangements are confirmed at checkout. In our experience, clinics new to PDRN tend to start with a single injectable and one retail product, then widen the order once patients begin asking about maintenance between sessions.

REJURAN® Turnover Ampoule and the Injectable Line

REJURAN® Healer is the flagship injectable, formulated with purified PN and delivered through intradermal microinjection. It is most commonly used for overall skin rejuvenation, improving texture, elasticity, and firmness, and is frequently incorporated into post-procedure recovery protocols. A typical course involves three sessions spaced several weeks apart, which makes it the entry point most clinics use when introducing a patient to the brand.

REJURAN® Dual Effect Ampoule combines the same PN technology with ingredients intended to support a brighter, more even-looking complexion. It is often selected for patients dealing with uneven tone, dullness, or post-inflammatory pigmentation alongside general skin-quality concerns, and uses the same intradermal technique as Healer.

REJURAN® Turnover Ampoule supports skin renewal and improves the appearance of textural irregularities and enlarged pores, making it a frequent add-on for clinics treating congested or uneven skin texture.

On the homecare side, REJURAN® Tone Up Booster is built around PDRN and brightening ingredients to support daily radiance between clinic visits. Paired with a REJURAN® turnover cream, this REJURAN® booster helps patients hold the benefits of professional treatment. REJURAN® Eye Cream is formulated for the delicate periorbital area and enriched with PDRN to support hydration and skin quality around the eyes, and is commonly recommended alongside professional eye-area treatment.

REJURAN®  Injection Protocol — Treatment Areas and Administration

REJURAN® products function as professional anti-aging skincare products through PDRN-based regenerative therapy rather than volume restoration [1]. On the face, treatment addresses fine lines, uneven texture, enlarged pores, and reduced elasticity. In the periorbital area, the injectable line is used for the thin skin around the eyes, where a controlled trial reported durable improvements in wrinkle depth and skin quality following PN treatment [2]. The neck and décolletage are frequently treated for crepey skin and age-related loss of firmness, and the hands for thinning skin and other visible aging signs. These areas are consistent with published expert consensus on PN-based aesthetic use [2].

Administration is by qualified medical professionals using intradermal or superficial subdermal technique, typically with fine-gauge needles in the 30G to 32G range. A standard course involves three initial sessions spaced two to four weeks apart, with maintenance generally recommended at roughly six-month intervals [2]. Technique selection, whether serial papule, linear threading, or another method, depends on treatment area and practitioner preference. REJURAN® microneedling delivery is used by some practitioners to apply the product across larger zones, which is useful when broader coverage is the goal.

REJURAN® is also commonly incorporated into post-procedure recovery plans following laser resurfacing, dermabrasion, and similar treatments. Patients typically notice initial improvements in texture and radiance within several weeks, while changes in elasticity and overall condition continue developing over the following months. Technique and protocol vary by product and patient presentation, so practitioners should consult the applicable IFU for complete administration guidance.

Regulatory Status

REJURAN® is not currently FDA-cleared for injectable use in the United States, and any clinical use in the US market falls outside current FDA regulatory authorization. Practitioners asking is REJURAN® FDA approved should treat that gap as a practical constraint rather than a technicality, since it directly shapes which markets a clinic can legally treat patients in with the injectable line.

Outside the United States, the professional injectable range reportedly carries CE marking as a Class III medical device for tissue restoration and aesthetic improvement of the face, neck, décolleté, and hands, and is approved by South Korea’s Ministry of Food and Drug Safety. Regulatory status should be verified independently with local authorities, including Health Canada and Australia’s Therapeutic Goods Administration where applicable, since approval requirements and product classifications vary by market.

Comparing REJURAN® to Other Regenerative Skin Boosters

REJURAN® vs NUCLEOFILL™

Both fall under the polynucleotide category, using salmon-derived DNA fragments to support collagen production and tissue repair [1]. The difference is formulation architecture: REJURAN® is built around a standardized PN formulation, while NUCLEOFILL™ comes in several variants tailored to different treatment depths. Practices that buy NUCLEOFILL™ for layered protocols often stock REJURAN® alongside it for broader coverage.

REJURAN® vs SUNEKOS®

SUNEKOS® takes a different mechanistic route, combining amino acids and hyaluronic acid to support collagen and elastin production rather than relying on PN/PDRN biostimulation [2]. Hydration-focused rejuvenation is where it tends to be selected, whereas REJURAN® is more often chosen when skin recovery and resilience are the primary objective. That distinction is worth confirming before a clinic decides to buy SUNEKOS® as an alternative.

REJURAN® vs JALUPRO®

JALUPRO® relies on amino acids as building blocks for collagen synthesis, with the HMW formulation adding hyaluronic acid for hydration. Both can sit within one skin-rejuvenation program, and practices that buy JALUPRO® for amino-acid-based protocols often add REJURAN® as a complementary option.

REJURAN® vs PROFHILO®

PROFHILO® uses stabilized hyaluronic acid to improve hydration and laxity through bioremodeling, a different mechanism from PN-driven repair [2]. Clinics that buy PROFHILO® for hydration-led treatment often pair it with REJURAN® when a patient’s concerns extend into broader skin-quality territory.

REJURAN® vs PLINEST®

PLINEST® is also polynucleotide-based, and the two differ mainly in formulation concentration and manufacturer specification rather than core mechanism. Because both sit in the same category, practices already set up to buy PLINEST® frequently evaluate REJURAN® directly against it before standardizing a PN protocol around one brand.

REJURAN® vs EXOJUV

EXOJUV departs from the PN/PDRN model entirely, using stem cell-derived exosomes carrying signaling molecules and growth factors. REJURAN® instead relies on a mechanism backed by a longer history of regenerative-medicine research. Clinics exploring newer exosome-based options before they buy EXOJUV tend to weigh that novelty against an established clinical track record.

Juvelook vs REJURAN®

The Juvelook vs REJURAN® comparison sits across a wider gap than the others here. Juvelook uses PDLLA microspheres combined with hyaluronic acid to stimulate collagen production, which is collagen stimulation by scaffold rather than tissue repair by signaling. Practitioners generally choose between the two based on whether structural collagen stimulation or broader skin-quality repair is the goal for a given patient.

REJURAN® Safety Profile

REJURAN® carries an established safety profile built on extensive clinical use in South Korea and a growing base of published research. Most reported reactions are mild, temporary, and typical of intradermal microinjections, consistent with controlled clinical trials [2]. Injection-site papules are a normal, transient part of the procedure; they typically resolve within hours to a few days. Localized redness usually subsides within 24 to 48 hours, and mild bruising and tenderness at injection sites are minor and self-limiting.

Treatment is generally not recommended for patients with known hypersensitivity to PDRN, PN, or salmon-derived ingredients, including a history of fish or salmon allergies, or for those with active infection or open wounds at the treatment site, during pregnancy or breastfeeding, or with autoimmune skin disorders or a documented tendency toward keloid scarring. Serious adverse events remain uncommon when the product is administered by qualified practitioners using proper technique. Practices should source authenticated products through authorized suppliers rather than unverified resellers.

FAQs

What is REJURAN®?

REJURAN® is a Korean PDRN skin booster brand using salmon-derived polynucleotide to stimulate skin regeneration and repair [1]. It is available as professional injectables, including Healer and the Dual Effect and Turnover ampoules, alongside a separate homecare range.

What is REJURAN® made of?

REJURAN® injectables contain purified polynucleotide and polydeoxyribonucleotide, hydrolyzed DNA fragments extracted from salmon [3]. These components are biocompatible and biodegradable, supporting tissue repair and wound healing. The homecare range uses cosmetic-grade actives at lower concentrations for topical application only.

How long does REJURAN® last?

A typical protocol involves three sessions spaced two to four weeks apart, with results building progressively and maintenance sessions generally recommended to sustain benefits [2]. Because PN and PDRN stimulate fibroblast activity and collagen remodeling, improvements continue developing after the course is complete.

When does REJURAN® take effect?

Initial improvements in skin texture and radiance often appear within several weeks of starting treatment [1]. More significant regenerative changes, including improved elasticity and dermal quality, typically develop over two to three months following completion of the course.

How long do REJURAN® bumps last?

Small papules at injection sites are a normal, expected response to intradermal PN or PDRN administration [2]. They typically resolve on their own within hours to a few days and are considered a transient, self-limiting part of the process.

Is REJURAN® FDA-approved?

No. REJURAN® is not currently FDA-cleared for the United States injectable market. Regulatory status varies by region, with CE marking reported in the European Union and approval by South Korea’s MFDS. Practitioners should verify current local requirements before clinical use.

REJURAN® vs SUNEKOS® — how do they compare?

They work through different mechanisms: REJURAN® uses salmon-derived PN/PDRN to activate fibroblasts and support tissue repair, while SUNEKOS® combines amino acids and hyaluronic acid for hydration and extracellular matrix support [2]. PN-based treatment tends to suit dermal repair and thin or damaged skin, while amino acid and HA formulations lean toward structural support and hydration.

Is REJURAN® injectable or topical?

Both exist under the brand [4]. The professional injectable line is administered by licensed practitioners via intradermal injection. The homecare range covers creams, serums, masks, and toners for daily topical use, formulated at different concentrations and not interchangeable with the injectable line.
