I'm Dr. Hyunji Kim, director and lead physician at Delphic Clinic in Gangnam. I trained at Korea University Medical Center, and I am a member of the Korean Academy of Aesthetic Surgery & Laser Medicine and the Korean Filler Society. My focus is lifting, laser and anti-ageing care, and skin boosters made from salmon DNA are a regular part of that work.
"Which is the best Korean PDRN?" is a question I hear several times a week, often from patients who have searched best Korean PDRN and found a different winner on every page. I understand the wish for one clear name. In this post I explain why I never give one, and what I look at instead when I choose for a patient.
Why 'best Korean PDRN' has no single answer
The difference between PDRN and PN, and between the salmon injection and Rejuran, is in my Korean PDRN comparison of salmon injection and Rejuran. I will not repeat it here. The short version: they are different tools, and a tool is only right for a particular job.
Online rankings tend to rank brands, but most of what decides your result is whether the product matches your concern and whether it is injected well. That is why two people can use the same product and write opposite reviews, which I explore in how to read Korean PDRN reviews.
Goal first: matching a salmon DNA booster to your skin
Label checks that matter more than the brand name
- Is it PDRN or PN? The label should say which.
- Is the vial sealed, and will it be opened in front of you?
- How many cc will be used on your face?
- Is it injected by a doctor, and by hand or with a device?
At Delphic, the salmon injection is opened in front of the patient. I think every clinic should offer that without being asked.
| Salmon Injection 3cc (Opened in front of patient) | ₩180,000$130 |
| Salmon Injection (First-visit trial) | ₩99,000$70 |
Injection technique changes the result more than the vial
Skin boosters work where they are placed. Even spacing, the right depth and enough coverage for the area are what patients feel as smoother, better-hydrated skin over the following weeks. A premium product injected unevenly can disappoint; a well-chosen one injected carefully usually does not.
Price follows the product and the amount. For how the salmon injection is priced and compared, see my polynucleotide Korea cost guide.
| Rejuran Healer 2cc | ₩350,000$250 |
| Rejuran I 1cc | ₩250,000$180 |
| Rejuran HB 1cc | ₩300,000$220 |
| Rejuran S 1cc | ₩300,000$220 |
| Painless Pain-free Rejuran 3cc | ₩350,000$250 |
| Painless Pain-free Rejuran 6cc | ₩600,000$430 |
| Painless Pain-free Rejuran Eye 3cc | ₩350,000$250 |
| Painless Pain-free Rejuvelook 5cc | ₩500,000$360 |

Questions to ask when a clinic pushes one brand
Copy these and send them to any clinic that tells you its PDRN is the one to get.
- Why this product for my skin, rather than PN or another option?
- What result should I expect, and after how many weeks?
- How many sessions do you suggest, and how far apart?
- Can I see the sealed product before the injection?
The right booster is the one chosen for your skin, not the one with the loudest name.— Dr. Hyunji Kim, Delphic Clinic
Skin that won't gain much from any PDRN
- Sagging that needs lifting. No booster lifts tissue.
- Deep volume loss, which needs volume support rather than skin quality work.
- Active infection or inflammation at the injection site.
- Anyone allergic to fish-derived ingredients.

Before the procedure, Dr. K carefully examined my skin condition and explained everything in a kind and easy-to-understand way, which made me feel very comfortable and reassured.

It’s definitely a clinic I would love to visit again.

They explained everything clearly in English and didn’t try to oversell unnecessary treatments, which I really appreciated. The clinic is very clean and modern, and the whole process felt professional and well-organized.

Frequently asked questions
What is the best Korean PDRN?
There is no single answer. The right choice depends on your skin goal, whether PDRN or polynucleotide suits it better, and how it is injected. A doctor who examines your skin can match the product to the goal.
Is Rejuran the same as PDRN?
No. Both come from salmon DNA, but Rejuran is based on polynucleotide (PN), while the PDRN Salmon Injection uses PDRN. They are different ingredients in different products.
How can I check that my PDRN is genuine?
Ask to see the sealed vial or packaging before the injection and to have it opened in front of you. At Delphic, the salmon injection is opened in front of the patient.
Does the brand of PDRN matter more than the injector?
In my experience, choosing the right product for your skin and injecting it evenly at the right depth affects the result more than the brand name alone.
