Yeoksam Station Rejuran Review: Is it true that manual injection is better?

‘Director, I want to receive it manually.’
This is something I often hear from people who come to Yeoksam Station for Rejuran procedures these days.
Actually, Rejuran is a procedure that involves pain.
Among them, manual injection tends to be a bit more painful than when performed with the DermaShine device, so for those sensitive to pain, we usually recommend DermaShine first.
Nevertheless, more and more people are specifically requesting manual injections.
What could be the reason?
Today, I will honestly tell you the reasons as I've observed them in clinical practice.
<Treatment Philosophy>
The key is ‘control.’
The main ingredient of Rejuran is polynucleotide (PN) extracted from salmon DNA.
This ingredient stimulates fibroblasts in the dermis to help produce collagen.
Related studies report that PN enhances the activity of dermal fibroblasts and stimulates the signaling pathway (ERK pathway) involved in collagen synthesis.
However, there's one important thing here.
The drug must be injected precisely into the dermis.
But the thickness of the dermis varies across the face.
Under the eyes it's thin, on the cheeks it's thick, and around the mouth it's somewhere in between.
Even within the same face, the thickness differs.
This is where manual Rejuran injection at Yeoksam Station becomes significant.
By checking the skin thickness of each area with fingertips, the depth can be finely adjusted.
The same goes for dosage distribution.
A little more in areas of concern, and less in relatively good areas.
If DermaShine's strength is uniformity, manual injection's strength is ‘control.’
The reason why patients prefer it first
More and more people are coming to Cordelia Clinic for manual Rejuran injections.
In fact, the results of Rejuran largely depend on the practitioner's anatomical understanding and proficiency in manual injection.
Even with the same product, a delicate treatment plan tailored to individual skin characteristics is key to satisfactory results.
When you experience it yourself, the feeling of ‘it's tailored to my skin’ is different.
It seems natural for people to want to focus more on the areas they are concerned about during the procedure.
Choosing it even while knowing it's a bit more painful means there's a high expectation for customized care for each area, doesn't it?
So, who is it suitable for?
Not everyone necessarily needs to go for manual injection.
The appropriate method can vary depending on your concerns.
Cases where manual injection is suitable:
· Main concern is delicate areas like around the eyes and mouth
· Skin with significant variations like pores or scars
· Those who previously received DermaShine but were unsatisfied with specific areas
Cases where DermaShine is more suitable:
· Highly sensitive to pain
· If you want to uniformly refine overall skin texture
· When you want to efficiently care for a large area at once
Today, I explained why manual Rejuran injections at Yeoksam Station are increasingly chosen.
It's not that manual injection is a superior procedure.
Its strength lies in the ability to adjust the depth and dosage for each area, allowing for more focused care on areas of concern.
However, if you are sensitive to pain or want to uniformly refine the overall skin texture, DermaShine might be a better fit.
The correct answer varies from person to person.
Therefore, the decision on the procedure method requires a 1:1 consultation to first identify the areas of concern, which will lead to a more accurate direction.
Even if it's not our Cordelia Clinic, I recommend visiting a trustworthy medical institution, consulting directly with medical staff, and making a careful decision.
For Rejuran at Yeoksam Station, finding the method that suits your skin is more important than the procedure technique itself.
Since skin takes time to recover if overstressed, I hope you don't rush into a decision and proceed after thorough research.
We will be with you throughout that process.
This has been Kim Da-jung, head director of Cordelia Clinic.
Thank you.

Frequently Asked Questions
Why is manual Rejuran injection more painful?
Yes, manual Rejuran injection tends to be a bit more painful than when performed with the DermaShine device. This is because the practitioner directly injects by hand, finely adjusting the depth and dosage according to skin thickness and area. For those sensitive to pain, DermaShine may be recommended first.
What is the biggest advantage of manual Rejuran injection?
The biggest advantage of manual Rejuran injection is ‘control.’ The practitioner can check the skin thickness of each area with their fingertips and finely adjust the depth and dosage of the drug injection. This allows for customized intensive care for delicate areas like around the eyes and mouth, or for skin with significant variations like pores and scars.
In what cases is DermaShine Rejuran treatment more suitable?
DermaShine Rejuran treatment is more suitable if you are highly sensitive to pain, want to uniformly refine overall skin texture, or wish to efficiently care for a large area at once. DermaShine's strength lies in uniform drug injection.
What should I consider before Rejuran treatment?
Before Rejuran treatment, it is important to consult with medical staff in a 1:1 session to determine whether manual injection or DermaShine is more suitable for your skin concerns. The optimal treatment method can vary depending on individual skin characteristics and areas of concern, so a careful decision is necessary.
What is the main ingredient of Rejuran and what are its effects?
The main ingredient of Rejuran is polynucleotide (PN) extracted from salmon DNA. This ingredient is known to stimulate fibroblasts in the dermis to help produce collagen, contributing to skin regeneration and improved elasticity.
