Rejuran Healer Trueskin Essence - Topical PDRN Formula for Microneedling
This is not an injectable. Rejuran Healer Trueskin Essence is a topical 2% polynucleotide formula applied to the skin surface and driven in with a microneedling device, derma roller or tok stick. Every other product in the Rejuran range is injected; this one is not, and ordering it expecting a vial of injectable PN is a mistake worth avoiding.
What it is for is the recovery phase. Applied immediately after microneedling, fractional laser or a similar procedure, it delivers polynucleotide into skin whose barrier is already open — supporting the healing process at the point where the skin is most receptive and most in need of it.
It also opens PN treatment to patients who will not accept injections. The delivery is shallower and the dose less controlled than a syringe, so it is not equivalent — but for a needle-averse patient it is a genuine route into the category.
Applied to the skin surface via microneedling, derma roller or tok stick. The only non-injectable in the Rejuran line.
The same salmon-derived active as the injectables, at the concentration used in Healer Black.
Applied straight after microneedling or fractional laser, when the barrier is open and the skin most receptive.
A route into PN treatment without injection — shallower delivery, but a real option where a syringe is refused.
Why practitioners stock Trueskin Essence
Works with any microneedling device, derma roller or tok stick — no proprietary applicator and no new capital purchase.
Turns a microneedling or laser appointment into a combination treatment, with an obvious chargeable addition.
A meaningful part of any patient list declines needles. This is a way to offer them the active without one.
2 × 2 mL, so a single pack covers more than one application depending on area and technique.
Applications
Uses for topical PN applied after a barrier-opening procedure. Permitted indications vary by market — work from the manufacturer’s instructions for use and the regulations where you practise.
Applied immediately after microneedling or fractional laser, supporting the skin through the recovery phase when it is most receptive. The primary use for this product.
Turning an existing microneedling or laser treatment into a combination procedure, with an obvious chargeable addition and no new equipment needed.
A route into PN treatment for patients who decline injections. Delivery is shallower and the dose less controlled, so set expectations proportionately.
Used as part of a regular maintenance protocol alongside light resurfacing, for patients managing skin quality over time rather than correcting a specific concern.
This is a topical product for professional use alongside a resurfacing procedure. Which applications are permitted, and what training is required, is determined by the regulatory framework where you practise. Korea Filler Experts supplies the product; nothing here is a recommendation to treat any medical condition.

Before you order
- Confirm you want a topical. This is the one non-injectable in the Rejuran range. If you want injectable PN, order Healer, HB, I, S or Skinbooster.
- Check the lot number and expiry on the carton against the syringes.
- We do not dispatch stock with under 6 months of shelf life remaining unless agreed in advance.
- Store as stated on the carton. Do not freeze, and protect from light.
Volume pricing is unusually steep on this item — the per-unit rate drops substantially at 10 and 20. Worth factoring in if you run regular microneedling lists.
What each component does
Topical delivery is not equivalent to injection
Worth being precise about, because the two are often presented as interchangeable and they are not.
Injection places a measured volume at a chosen depth in the dermis. You control dose and plane, and the active reaches the fibroblast population directly.
Microneedling delivery drives product through temporary channels in the epidermis and upper dermis. Penetration depends on needle depth, device, technique and how intact the barrier was to begin with — so the dose reaching the dermis is neither measured nor consistent.
That does not make it useless. It makes it a different treatment, delivering less PN less deeply, with correspondingly more modest effects. Describing it as “Rejuran without the needles” would be overselling it; describing it as a way to add PN to a resurfacing procedure, or to treat a needle-averse patient, is accurate.
Why the post-procedure window matters
Applied immediately after microneedling or fractional laser, the formula meets skin whose barrier is temporarily open — which is both why absorption is better at that moment and why the application should be sterile and the product fresh.
Opening the barrier works in both directions. The same channels that admit the polynucleotide admit anything else on the skin surface, so cleansing, product handling and technique matter more here than for a leave-on cosmetic.
PN or PDRN?
Both terms describe purified DNA polymers from salmon or trout and are used interchangeably across most of the market. The distinction is molecular weight — PDRN generally shorter-chain, PN longer. A 2025 review proposed a 1500 kDa boundary, but that is a naming convention rather than a regulatory standard.
One relevant point for a topical: molecular size affects penetration. Larger polymers cross a compromised barrier less readily than smaller ones, which is part of why topical delivery is less efficient than injection.
How it works
Polynucleotides are purified DNA polymers, in this case from salmon. The mechanism is understood to involve adenosine A2A receptor activation, which supports fibroblast activity and collagen synthesis and modulates the local inflammatory environment.
The limiting factor for a topical is delivery. An intact stratum corneum is an effective barrier and polynucleotide is a large molecule, so very little crosses on its own. Microneedling and fractional laser create temporary channels through the epidermis and into the upper dermis, and it is through those that the product reaches tissue where it can act.
How much arrives depends on needle depth, device, technique and the skin itself — which is why this route delivers a smaller and less consistent dose than injection, and why the effect is correspondingly more modest. The window is also short: the channels begin closing within hours, which is why application happens immediately after the procedure rather than later.
How to use Trueskin Essence
Reference information for licensed practitioners. This product is applied topically and must not be injected. Technique must follow the manufacturer’s instructions for use and the regulations applying where you practise.
Step by step
-
Confirm the product
Trueskin Essence is topical. Check the packaging before any procedure where injectable Rejuran is also in the room — they are not interchangeable.
-
Cleanse thoroughly
Full cleansing and antisepsis before the resurfacing procedure. You are about to open the barrier, and whatever is on the skin goes in with the product.
-
Perform the resurfacing step
Microneedling, fractional laser or equivalent, to your usual protocol and depth. That protocol governs the treatment; this product supports it.
-
Apply immediately
Apply to the treated area while the channels are still open. The absorption window is short, so have the syringe ready rather than opening it afterwards.
-
Work it in evenly
Distribute across the treated area with gentle even pressure, or continue passes with the device per your protocol. Uneven application gives patchy results.
-
Leave in place
Do not cleanse off afterwards. Advise the patient to leave the skin alone — no cleansing, make-up or active products for the rest of the day.
Administration notes
Never inject this product. It is formulated and packaged for topical application. If injectable Rejuran is also in use in your clinic, keep the two physically separated and check the packaging before every procedure — the syringe format makes confusion plausible.
Set proportionate expectations. This delivers less polynucleotide, less deeply, than an injection. It is a worthwhile addition to a resurfacing procedure and a genuine option for a needle-averse patient. It is not a substitute for an injectable PN course, and presenting it as one will disappoint.
- Single use. Do not retain an opened syringe for another patient.
- Do not apply over active infection, inflamed skin or open lesions beyond the controlled channels of the procedure itself.
- Ask directly about fish allergy — the active is salmon-derived, and an open barrier increases exposure.
- Follow your resurfacing device’s own protocol for depth and passes.
After treatment
- Redness and a warm, tight sensation are expected after any resurfacing procedure and typically settle within 24 to 48 hours
- No cleansing, make-up or active skincare for the rest of the day
- Avoid saunas, steam rooms, swimming and strenuous exercise for 48 hours
- Strict sun protection — freshly resurfaced skin pigments readily
- Avoid retinoids, acids and vitamin C for several days
- Any spreading redness, increasing pain or signs of infection needs reviewing promptly
Storing and handling Trueskin Essence
Store as stated on the carton and in the manufacturer’s insert, protected from light. Do not freeze — freezing damages the polynucleotide structure.
If you stock injectable Rejuran, store this physically apart. The syringe presentation makes confusion possible, and the consequence of injecting a topical formulation is serious.
Single patient. Do not retain an opened syringe for another appointment — there is no preservative system intended to support that, and it is applied to a compromised barrier.
For topical use only — do not inject. Do not use if the formula is discoloured or contains visible particles, if the expiry date has passed, or if the packaging seal is broken. Dispose of unused product as clinical waste in line with local requirements.
What's included with Trueskin Essence
Microneedling device, derma roller or tok stick is not supplied — this product works with equipment you already have. Needles and consumables for your resurfacing procedure are separate.
Trueskin Essence — frequently asked questions
Is this an injectable?
No. Rejuran Healer Trueskin Essence is a **topical** formula applied to the skin surface and driven in with a microneedling device, derma roller or tok stick.
It is the only non-injectable product in the Rejuran range, and it must never be injected. If you want injectable PN, order Healer, HB, I, S or Skinbooster.
Is it as effective as injectable Rejuran?
No, and we would rather say so plainly. Injection places a measured dose at a chosen depth; microneedling delivery drives product through temporary channels, so the amount reaching the dermis is neither measured nor consistent.
It delivers less polynucleotide, less deeply, with correspondingly more modest effects. It is a worthwhile addition to a resurfacing procedure and a real option for a patient who refuses needles — but it is not “Rejuran without the injections”.
When should it be applied?
Immediately after microneedling, fractional laser or an equivalent procedure, while the channels are still open. The absorption window is short, so have the syringe ready rather than opening it afterwards.
Can I use it as a stand-alone facial without microneedling?
Applied to intact skin, very little will penetrate — polynucleotide is a large molecule and an intact stratum corneum is an effective barrier.
The product is designed around a procedure that opens that barrier. Without one, you are largely applying an expensive surface essence.
What microneedling depth should I use?
Follow your device’s own protocol and your usual settings for the indication being treated. The resurfacing procedure governs the treatment; this product supports it rather than dictating technique.
Does it contain the same active as injectable Rejuran?
Yes — salmon-derived polynucleotide at a stated 2%, the same concentration as Rejuran Healer Black. The difference is the route, not the active.
Is it safe to apply to freshly lasered skin?
That is what it is designed for. But an open barrier admits whatever is on the skin, so cleansing, sterile handling and product freshness matter more here than for a leave-on cosmetic.
Ask about fish allergy as well — exposure through an open barrier is greater than through intact skin.
How many applications per pack?
The pack holds 2 × 2 mL syringes. How far that goes depends on the treated area and your technique — a full face uses more than a targeted zone.
How does it compare to Rejuran Tone-Up Booster?
Both are topicals applied after a resurfacing procedure. Trueskin Essence is a single PN formula focused on recovery and skin conditioning.
Tone-Up Booster is a two-part system pairing a PN solution with a second vial containing vitamin C, glutathione and tranexamic acid — aimed at skin tone rather than recovery alone.
Who can buy and use this product?
This product is intended for use by trained practitioners alongside a resurfacing procedure. We supply to professionals qualified to perform those procedures in their jurisdiction, and do not sell to consumers.
