What the carton, the label and your written plan should agree on

The product question
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
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.
The manufacturer's check
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.
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.
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.
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.
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
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.
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.
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.
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.
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.
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.
Beyond the box
Keeping the 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.
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.
At Rewind, one board-certified plastic surgeon carries every case — from the first consultation to the final follow-up. Because a face is a story, and a story deserves a single author.

Scientific evidence
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.
