What You Must Know Before Getting Rejuran in Seoul
Hello.
I'm Dr. Wi Young-jin, a specialist at Beautystone Clinic.
One question I get asked all the time is,
"What does Rejuran actually do?"
There's no shortage of content out there,
but finding truly useful information? That's a different story.

For those searching for Rejuran
in Seoul — especially around Hongdae and the surrounding area —
here's what I've learned from 5 years of clinical experience.
Rejuran, PN, HA: Ingredients & Treatment Overview
Medical papers can be dense, right?
Let me break down two key studies for you.
This study isn't the highest level of evidence,
reducing wrinkles, improving skin texture, and enhancing elasticity, with statistically significant results in several studies
In short: fewer wrinkles, smoother texture, and firmer skin.
Rejuran Healer, PN 20mg/ml
Increased skin thickness,
reduced wrinkles,
improved skin texture
In a randomized split-face trial of 27 participants, the PN-treated side showed significantly higher GAIS scores at week 16 compared to HA filler, and greater reduction in skin roughness by week 28.
1. Know Exactly What Rejuran Is Before You Get It

Rejuran
is a polynucleotide (PN) extracted from salmon,
It's injected directly into the skin.
Simply put, it contains the building blocks of cells —
fragments of DNA.
So what does it actually do?
Anti-inflammation & regeneration.
PN stimulates collagen synthesis and promotes new blood vessel formation.
Improves aging signs and fine lines.
Collagen synthesis fills in fine lines and minimizes pores — anti-aging effect.
Improves depressed acne scars (cell regeneration).
Collagen fills in sunken scar areas, gradually lifting them up.
Restores skin barrier + reduces sensitivity.
Damaged skin barrier regenerates, bringing sensitive skin back to its normal state.
✔ This is not a volume-filling treatment like filler,
✔ nor does it affect muscles like Botox.
It works by helping skin cells produce collagen on their own —
which is why results look natural.
Many patients in Seoul ask about Rejuran:
"Will I see a big difference after just one session?"
Honestly speaking,
rather than dramatic changes,
think of it this way: 2. Who is it most effective for?They absorb naturally on their own.
In my clinical experience,

there are certain skin types that respond especially well to Rejuran 👇
✔ Rough skin texture and enlarged pores from severe acne in younger years
✔ Fine lines from thinning skin
✔ Overall loss of elasticity
Satisfaction tends to be high in these cases.
On the other hand,
❗ Deep nasolabial folds
❗ Significant volume loss
For these concerns,
Rejuran alone isn't the right choice.
In those cases,
combining filler or other treatments is recommended.
Based on patients visiting our clinic in Seoul,
"Is something wrong with my skin at this age?"
tend to report the highest satisfaction.
Late 30s to early 50s
No skin concerns? Rejuran may not be necessary.
Rejuran HB is a great option though → for a glass-skin glow effect.
