The product question

How can I check that the Rejuran used is genuine?

The short answer

Look at the sealed product before the injection begins. The carton should name the manufacturer, PharmaResearch, and the Rejuran line and volume written on your plan, and it should carry a lot number and an expiry date that are printed clearly and have not passed. On packs made since the manufacturer's 2023 packaging update, a QR code on the back of the box and an NFC tag on the blister pack let you run the manufacturer's own authenticity check.

Asking to see the pack is an ordinary request at the start of a session.

The second thing people search for is what the box and lot number should actually show. There are four details to read: the product line, the volume, the maker, and the lot and expiry block. The lot number is the batch code the manufacturer assigns, and it is the detail worth copying into your own notes, because it is the one that can be traced if a question comes up later.

This page stays with what the manufacturer has published and with what Rewind's own list states. It does not describe any private verification method, and it cannot tell you anything about a product you were given on another occasion.

Reading the pack

What to read on a Rejuran carton before the first injection

A minute with the pack answers most of the question. Read these four details in order, and compare each with the line on your written plan.

detail 01
The Rejuran line
Healer and the eye line are different products for different skin. The name on the carton should be the line your plan names for the area being treated.
detail 02
The volume
Rewind lists Healer at 2cc and 4cc and the eye line at 1cc. The total volume opened should match the volume you were quoted for.
detail 03
The maker
Rejuran is a PharmaResearch brand. The manufacturer's name and the product name should be printed cleanly, without stickers placed over them.
detail 04
Lot number and expiry
Both should be legible and complete. A smudged, scratched or missing code, or a date already passed, is a reason to stop and ask before anything is opened.
Tag

The manufacturer's check

Using the NFC tag and QR code on Rejuran packaging

In October 2023 PharmaResearch announced a full packaging renewal for four Rejuran products. The change added an authentication layer that both clinics and patients can use, and the manufacturer said it was introduced to track distribution and stop unauthorised exports of the product.

01QR

A QR code on the back of the Rejuran carton

According to the announcement, scanning it lets a provider or a patient check the product's authenticity and open the user manual. The code sits beside a DOT mark that the manufacturer describes as its patented technology.

02NFC

An NFC authenticator on the blister pack

The tag is attached to the blister pack inside the carton, so it travels with the syringes themselves. The manufacturer states that it can be tracked anywhere in the world.

03Older packs

When a pack does not carry the newer features

Stock made before the renewal, or packed for a particular market, may look different. If a feature you expected is absent, ask about it at the chair and read the four printed details instead of assuming the worst.

04Limits

What a verified Rejuran pack cannot tell you

A genuine product still carries the ordinary risks of injection, and it says nothing about whether the treatment suits your skin. Those questions belong to the examination that comes before the pack is opened.

Plan and product

Why Rewind ties the Rejuran product to your written plan

A product check only works if you know what you are checking against. At Rewind the reference point is the plan: the line and the volume are named on it, and both come from a published list.

01Named lines

Each Rejuran item on the list names a line and a volume

Healer 2cc, Healer 4cc and the eye line at 1cc each have their own entry. A carton can be read against a single line of the quote.

02One doctor

The doctor who examines you is the one who injects

Rewind is a single-surgeon practice. Dr. Jonghwan Choi chooses the line, sets the volume and carries out the injection, so a question about the product goes to the person responsible for the choice.

03Language

Label questions can be asked in your own language

Interpreter-assisted consultation is available for international patients. A lot number or an expiry format is easier to query when nothing is lost in translation.

There are three natural moments for a product question. At booking, tell the clinic you would like to see the pack. At the chair, look before the seal is broken and compare the line, volume, lot and expiry with your plan. Afterwards, write the lot number down or keep a photograph of the carton label for your own record. The clinic occupies floors four and five of the Richro Building in Apgujeong, with appointments on Monday, Tuesday, Wednesday and Friday, 10:00 to 19:00, and Saturday, 10:00 to 16:00.

Thursday and Sunday are closed. If you are only in Seoul for a few days, raise the product question when you book so it does not have to be squeezed in at the last moment.

Rates

Price list

Rejuran lines and volumes on Rewind's price list

Each Rejuran line appears once, at a stated volume. These are the entries your carton is checked against, and the same list is used for every patient.

Rejuran Healer 2ccFacial skin, one session
₩300,000
Rejuran Healer 4ccWider coverage in one session
₩600,000
Rejuran Eye 1ccThe eye line, for thin skin below the eye
₩200,000
Recovery packageRejuran Healer 4cc with soothing device care and a recovery IV drip
Quoted at consultation

VAT is added to every listed rate at payment, and anaesthesia, where used, is included in the rate. A price on its own does not tell you what is inside a syringe; the carton and your written plan do.

Fit

Beyond the box

When the Rejuran product check matters most, and what it cannot settle

Worth doing at every Rejuran session

  • Your first session, when you do not yet know how the clinic presents its products
  • A course across several visits, so each lot number can be kept together
  • A plan that uses more than one line, such as Healer and the eye line together
  • Any session where the volume opened seems different from the volume quoted

Questions a carton cannot answer

  • Whether a booster suits a jaw line that has dropped or a deep fold; it will not move either
  • A known sensitivity to fish-derived material, which must be raised before the product is chosen
  • Inflamed acne, infection or broken skin at the injection site
  • Pregnancy or breastfeeding, and any recent filler or device work in the same area
After

Keeping the record

After a checked Rejuran session: aftercare and your product record

The product check ends when the pack is opened, but the record is useful for as long as you keep having treatment. Rewind's Rejuran aftercare runs alongside it.

Same day
Note the lot number
Write it down, or keep a photograph of the label, together with the date, the line and the volume. Sauna, hard exercise and alcohol wait until tomorrow.
Days 1–3
Bruises and bumps settle
A bumpy feel, bruising and swelling ease within two to three days. Massage, strong pressure, smoking, sauna and swimming pools are avoided.
Following weeks
Moisturise and protect
The skin can feel dry after the injection, so moisturiser and sunscreen are applied carefully while it settles.
Next session
Bring the record with you
If a reaction ever needs to be looked into, the lot numbers from earlier sessions are the first thing the doctor will want to see.

Bruising, swelling, redness, stinging and small raised points are the common effects, and an allergic reaction to an ingredient can cause red inflammation. Infection and vascular occlusion are rare but serious with any injection; increasing pain, blanching or dusky skin means contacting the clinic the same day.

Questions

Checking genuine Rejuran: questions patients ask

How can I check that the Rejuran used is genuine?
Ask to see the sealed pack before the injection. Check that it names PharmaResearch and the Rejuran line and volume on your plan, and that the lot number and expiry date are clear and current. On newer packs, the QR code on the back and the NFC tag on the blister run the manufacturer's own check.
What should the product box and lot number show?
The box should show the Rejuran line, the volume, the manufacturer's name, a lot number and an expiry date. The lot number is the batch code. Printing should be clean and complete; a code that is scratched off, covered or missing is a reason to ask before the seal is broken.
What is the NFC tag on newer Rejuran packs for?
PharmaResearch added an NFC authenticator to the blister pack in its 2023 packaging renewal, alongside a QR code on the carton. The manufacturer says the system lets providers and patients verify authenticity and view the user manual, and helps it track where products are distributed.
The pack I am shown has no QR code. Should I worry?
Not automatically. Stock produced before the 2023 renewal, or packed for a particular market, can look different. Read the printed line, volume, maker, lot number and expiry, and ask the doctor about the packaging you see. A clear answer at the chair is part of a normal session.
My plan says Rejuran Eye but the carton says Rejuran i. Is that a mismatch?
Both names are used for the manufacturer's eye line. Rewind's price list calls it Rejuran Eye 1cc. Ask the doctor to confirm that the pack in front of you is the eye line and the volume on your plan, and note the lot number as usual.
Does a genuine product remove the risks of injection?
No. Bruising, swelling, redness, stinging and small raised points can follow any Rejuran session, and infection or vascular occlusion, though rare, remain possible. Increasing pain, blanching or dusky skin after treatment means contacting the clinic the same day.
What if the seal is broken or the expiry date has passed?
Say so before anything is injected. A pack that is already open, or a date that has passed, is not something to accept on reassurance alone. Ask for the product to be replaced with a sealed, in-date pack and check the new label in the same way.
Which Rejuran lines appear in Rewind's own materials?
The published price list names Rejuran Healer in 2cc and 4cc and Rejuran Eye in 1cc. Rewind's Korean aftercare sheet also includes instructions for Rejuran HB. Any line outside the price list is confirmed at consultation before it is written into a plan.

Scientific evidence

Reading on the material, and on asking questions in your own language

The first paper studies a PDRN preparation in bone cells and shows how widely this family of materials is researched, which is one reason the exact product name on a carton matters. The other two review how interpreters and shared language affect clinical care. None studies product authentication, and none was conducted at Rewind.
