Rejuran is the polynucleotide line made by PharmaResearch, the Korean company that built its business around purified salmon-derived DNA fragments. The active ingredient is PN — long-chain polynucleotide — rather than a cross-linked gel, so these products behave nothing like a filler. They are placed in the skin to hold water and to be worked on by the tissue over the following weeks, not to hold a shape.
What separates Rejuran from most of the skin booster category is how finely the range is divided. PharmaResearch does not sell one Rejuran; it sells several presentations that differ in chain length, whether hyaluronic acid is blended in, how fluid the material is, and the thickness of skin they were designed for. A clinic treating a thin lower eyelid and a clinic treating pitted acne scarring on a cheek are using two quite different products with the same brand name on the box.
The buyers are almost always clinics, dermatology practices and licensed injectors building a booster menu, and often ordering alongside topical anaesthetic because PN sessions involve a large number of small entry points. These are professional-use products, intended for administration by a trained practitioner.
The Rejuran range
Rejuran Healer Black
The high-volume presentation of the classic Healer formulation, supplied as 2 ml x 2 syringes per box. Polynucleotide derived from salmon DNA is the sole active. Because each box carries 4 ml in total, this is the version clinics reach for when treating a whole face, or face plus neck, in a single sitting rather than a small defined zone.
Rejuran Healer TrueSkin Essence
Also 2 ml x 2 syringes, formulated at 2% polynucleotide. It sits in the same general-rejuvenation role as Healer Black — texture, tone, hydration, overall skin quality — and is the presentation most often used as the standard full-face course.
Rejuran Skinbooster
The odd one out, and the one buyers most often misunderstand. This is a 3 ml x 3 vial vialled product built on c-PDRN with hyaluronic acid and four amino acids, made with PharmaResearch's DOT purification process. It is designed for a fine, distributed delivery across the surface rather than syringe-by-syringe placement, which makes it the natural fit for microneedling and mesotherapy-style protocols and for the glass skin finish it is marketed for. If you are looking for a prefilled syringe, this is not it.
Rejuran S
A 1 ml single syringe with the densest handling in the range. Rejuran S is the scar-focused presentation: deep atrophic acne scarring, textural irregularity, and skin that needs the material to stay put in a small area rather than spread. One syringe covers a defined region, not a full face.
Rejuran HB
PN blended with hyaluronic acid in a 1 ml syringe. The HA gives immediate hydration and a visible plumping effect on the day, while the PN component works over the following weeks. It is the version to order for early ageing, dehydrated or environmentally damaged skin, and for clients who want to see something on the first visit.
Rejuran I
The 1 ml periorbital presentation. Its texture is deliberately thin and fluid so it distributes evenly in very thin skin instead of sitting as a palpable bead. That single property is why it exists as a separate product: the under-eye is the one area where the heavier Rejuran presentations are unforgiving.
How to choose
The decision comes down to three things: how thick the skin is, how much area you are covering, and whether you want a same-day hydration effect.
| Product | Presentation | Composition | Best suited to |
|---|---|---|---|
| Healer Black | 2 ml x 2 syringes | PN | Full face and neck, larger treatment areas |
| Healer TrueSkin Essence | 2 ml x 2 syringes | PN 2% | Standard full-face rejuvenation course |
| Skinbooster | 3 ml x 3 vials | c-PDRN, HA, amino acids | Surface delivery, microneedling and meso protocols |
| Rejuran S | 1 ml x 1 syringe | PN, denser | Deep acne scars, localised texture correction |
| Rejuran HB | 1 ml x 1 syringe | PN + HA | Dehydrated skin, early ageing, visible day-one result |
| Rejuran I | 1 ml x 1 syringe | PN, low viscosity | Under-eye and other thin-skinned areas |
Clinics running a full booster menu usually stock one of the 2 ml Healer presentations as the volume workhorse, plus Rejuran I for eyes and Rejuran S for scar work. For technique, injection depth and treatment intervals, follow the prescribing information supplied by PharmaResearch in the box.
Storage and shipping
Rejuran syringes and vials are stored below 25 °C, away from direct sunlight, and must not be frozen. Keep the product in its sealed outer carton until the point of use. Every box we ship carries its printed lot number and expiry date on the original packaging, and we ship from Seoul with tracking so the transit window is short.
Buying Rejuran from MY SKIN KOREA
We source Rejuran directly in Korea and ship it from Seoul in original manufacturer packaging with full remaining shelf life — never repacked, never relabelled. Orders go out worldwide, and because we are based where the product is made, stock on the fast-moving presentations is usually immediate rather than back-ordered.
Clinics and distributors ordering in volume should look at our wholesale terms, which cover tiered pricing and consolidated shipping across brands. If you want a mixed pallet, a quote on a specific presentation, or advice on what a comparable Korean dermal filler line would add to your menu, contact us and we will come back the same working day.
Frequently asked questions
What is the difference between Rejuran Healer and Rejuran HB?
Healer is polynucleotide alone. HB adds hyaluronic acid, so it gives an immediate hydration and plumping effect on top of the PN action. HB also comes as a single 1 ml syringe rather than the 2 ml x 2 Healer box.
Can I use regular Rejuran under the eyes?
Rejuran I exists specifically for that region because its low viscosity distributes evenly in very thin skin. The thicker presentations are much less forgiving there. Refer to the manufacturer's instructions for placement.
Is Rejuran a filler?
No. It is not a cross-linked gel and it is not intended to create volume or contour. If you need lift or projection, you are looking for a dermal filler instead.
Which Rejuran should I order for acne scarring?
Rejuran S. It is the densest presentation in the range and is the one formulated for deep atrophic scars and localised textural work.
Do you ship Rejuran outside Korea?
Yes. We ship worldwide from Seoul with tracked courier services. Import rules differ by country, so tell us your destination and we will confirm what we can send before you order.
Is the packaging Korean domestic or export?
We supply original manufacturer boxes as produced for the market they are made for, unopened and with the lot and expiry printed by PharmaResearch. Tell us if you need a specific presentation and we will confirm availability.
Who can use these products?
Rejuran is for professional use by trained, licensed practitioners. We supply clinics, distributors and qualified injectors, not the general public.
