Hello. I’m Dr. Jo Wonjin, and I’ve been treating patients in Hongdae and Hapjeong for 10 years.

I heard dense embossing means better results. Is that true?
Should I choose Rejuran Healer or HB?
A lot of people are searching because they’re worried about things like this.
Because there are so many places offering it, it’s easy to think, “It’ll probably be similar no matter where I get it.”
But in fact, even with the same product, the experience can vary quite a bit depending on which layer it’s injected into, how much is injected, and how it’s administered.
Today, under the topic If You Got Rejuran in Hongdae and Didn’t See Any Effect, Be Sure to Read This,
I’ve organized 3 points that people considering Rejuran should definitely check before the procedure.
(effect, embossing, and how to choose a product)
If you read to the end, you’ll have a clearer 기준 for what to look at.


- Rejuran: how does it work on the skin?
Rejuran is a method of delivering salmon-derived PN (polynucleotide) ingredients into the skin.
Rather than filling volume like a filler, it is meant to help damaged cells function properly again.
To put it another way, it’s closer to changing the soil itself rather than just pouring water into a dry flowerpot.
When PN is introduced, collagen production is also promoted, and the internal recovery cycle becomes more active.

So rather than a dramatic change right after the injection, like “Wow, this is different!”
it tends to appear over 2 to 4 weeks as the skin texture becomes more refined and moisture and elasticity improve.
If you don’t know this, you may end up disappointed and think, “Nothing changed?”
Because this is a procedure that changes the internal environment rather than the surface, the evaluation 기준 should also be a little different.

- Rejuran embossing: does more visible embossing mean better results?
If you look at reviews about Rejuran in Hongdae, you’ll often see people saying, “It has to rise up nicely in little bumps for it to have been done properly.”
But that’s not always true.
If dryness is your main concern,
as shown in the photo below, it is right to distribute it evenly in a shallow layer so embossing forms.
The photo above shows the embossing shape formed after a direct Rejuran treatment. Embossing that forms densely and evenly like this is effective for improving dryness.
But what if the under-eye groove is deep or fine lines are deep?
In that case, you actually need to target a deeper layer and inject more precisely to get closer to the desired result.
At that time, the embossing may not stand out as much.
If you look at this photo, in the under-eye groove or nasolabial fold area, the embossing isn’t especially prominent and sits a bit flatter, right?
In particular, the under-eye area and the nasolabial line are parts of the face where the thickness can differ quite a bit.
One side should be shallow, another deeper. Only with this kind of detailed adjustment can you get changes that fit your concern.
That’s why it’s difficult to predict results based only on the size of the embossing.
In the end, the process of accurately understanding your condition during consultation and designing the treatment accordingly comes first.

- Rejuran product types: how should you choose?
Not all Rejuran in Hongdae is the same.
Rejuran Healer contains a high concentration of PN ingredients, so it is more focused on skin regeneration and restoring elasticity.
It’s good when you want the active ingredient in concentrated form. (It’s cost-effective too.)
However, the pain is... relatively strong.
(If you want to understand how to reduce the pain, please refer to the article below.)
On the other hand, Rejuran HB is a product that adds hyaluronic acid and an anesthetic ingredient.
While PN helps with regeneration, hyaluronic acid also helps retain moisture.
If you really can’t tolerate pain, or if your skin is so dry that it flakes often, HB may feel faster in terms of effect.
The photo above shows a self-treatment with Rejuran HB. It was done with a device because it was self-treatment, but when administering it, I recommend a manual injection. Manual injection is more effective.
- Frequently Asked Questions (FAQ)
Q. I bruise easily. Is that okay?
A. If the type of needle used and the injection depth are adjusted, the likelihood of bruising can be greatly reduced.
If you let us know in advance, we’ll take that into account and proceed accordingly. You don’t need to worry too much.

Q. How many sessions of Rejuran in Hongdae are usually needed?
A. It depends on the condition, but if you do about 3 sessions at 2- to 4-week intervals,
many people notice changes in skin texture or elasticity.
After that, some people come once every 2 to 3 months for maintenance.

In fact, with procedures, it’s really hard to tell good places from bad ones until you’ve actually experienced them.
If you read the article below, you’ll gain an eye for distinguishing good places.
- Hongdae Rejuran: key summary
- Rejuran principle: Since it is a procedure that boosts regeneration, it’s right to watch the progress steadily rather than expecting immediate change.
- Effect: Embossing size isn’t everything; what really matters is whether the treatment was designed to match your concerns.
- Product choice: Can you tolerate pain and value cost-effectiveness? Healer. Can’t tolerate pain and need improved dryness? HB

Thickness, concerns, and recovery speed are all different for everyone.
Rather than other people’s reviews, I hope you receive treatment effectively in a way that suits your own condition.
Thank you. This was Jo Wonjin.
