PN & PDRN Injections in Seongsu, Seoul
The difference between PN and PDRN, and why our regeneration recipe uses PN
PN and PDRN are often mentioned together, and many patients arrive unsure which is which. At Seongsu Melting Clinic in Seongsu, Seoul, Dr. Park Kyung-min explains the difference first, then builds treatment around PN (Rejuran) combined with Plamon in the clinic's regeneration recipe.
What are PN and PDRN?
Both come from purified salmon DNA, and both are used to support skin repair. The key difference is size. PDRN (polydeoxyribonucleotide) is made of shorter fragments. It has a long history in wound-healing medicine and is usually light and quickly absorbed.
PN (polynucleotide) uses longer chains. Because of that, PN forms more of a gel-like structure in the skin and tends to stay a little longer. Many physicians use PN when the skin needs both repair support and a physical scaffold for hydration. Rejuran is the most widely recognized PN brand in Korea.
Neither one is a filler, and neither one will lift loose skin. What they may do is help skin look calmer, more hydrated, and more resilient over a series of treatments.
How we approach PN & PDRN injections at Seongsu Melting Clinic
The clinic's approach centers on PN. Dr. Park is a key opinion leader for Rejuran and has also worked as a KOL for Plamon, a placenta-derived product. The clinic's premium regeneration injection combines the two in a recipe he developed, aiming to support repair from more than one angle.
This recipe is used for concerns such as redness, fine lines, dehydration, stretch marks, and acne scars. For simpler goals, plain Rejuran may be enough. Dr. Park will tell you which he recommends, and why, after looking at your skin.
A good fit if…
- Your skin is thin, dry, reactive, or slow to recover
- You have fine lines or early texture changes
- You have redness or sensitivity that limits other treatments
- You have stretch marks or acne scars and want regeneration support
Consider something else if…
- You have a fish or salmon allergy
- You are pregnant or breastfeeding
- You have active infection or inflamed acne on the day
- You are looking mainly for volume or a lifting effect
What to expect
After consultation, numbing cream is applied and the product is placed with small, evenly spaced injections. A session usually takes around 30 minutes.
Temporary bumps, redness, and small bruises are common and usually settle within a day or two. Most patients go back to work quickly. A short series a few weeks apart is typical, followed by maintenance if you like the result. Results vary, and pricing is explained at consultation.
Aftercare
- Avoid makeup on injection points for the rest of the day
- Skip saunas, alcohol, and hard exercise for about a day
- Keep skincare gentle and hydrating
- Use sunscreen every day
- Message the clinic if redness or swelling increases instead of settling
A note from Dr. Park
Dr. Park often tells patients that research and practice should feed each other. His PN and placenta recipe grew out of years of lecturing and working with these products. He also insists on genuine products at exact doses, because a recipe only means something if what goes into the syringe is exactly what is on the label.
Frequently asked questions
Is PN better than PDRN?
Not better, just different. PN is longer-chain and gel-like; PDRN is shorter and lighter. The clinic's regeneration recipe is built on PN.
What is Plamon?
Plamon is a placenta-derived product. Dr. Park combines it with Rejuran in the clinic's regeneration injection.
Will PN injections fill my wrinkles?
No. They support skin quality. For deeper lines or volume loss, other options may be more suitable.
