Dermatology Clinic Near Euljiro 1(il)-ga Station: Why Are Multiple Rejuran Treatments Needed?

Hello.

I’m Lee Kang-in, Director of Kind Global Clinic, and I make a point of listening carefully to each patient. For those looking for a dermatology clinic near Euljiro 1(il)-ga Station, I’d like to share some information about skin treatments.

Why Repeated Treatments Are Considered at a Dermatology Clinic Near Euljiro 1(il)-ga Station

How Long Does It Take to Notice Results?

If you’re looking into Rejuran, you may be wondering how many treatment sessions are needed.

It is commonly administered about 3–4 times at intervals of 2–4 weeks,

so some people ask, “Why do I need several sessions instead of just one?”

Rather than producing an immediate change, this treatment supports the skin as it goes through its own recovery process.

If you don’t understand how it works and assume that the changes you expect should appear right away, you may stop treatment before completing the course.

Today, I’ll explain how it works and the factors that can lead to different results, step by step.

A quick read may help you consider what to ask and check during a consultation^^

Rejuran is commonly known as a “skin booster,”

but it works differently from treatments that add volume by filling the skin, such as hyaluronic acid injections.

Its key ingredient is “PN.”

It is a purified substance derived from salmon DNA that helps support the tissue regeneration process.

When PN reaches the dermis beneath the skin, damaged tissue begins responding as it heals.

Rather than filling the face with something,

you can think of it as sending the message,

“This area needs a recovery process,”

and helping the skin continue its regeneration process.

This process may stimulate the production of collagen and elastin, which make up the skin,

Skin firmness

Skin texture

and other aspects may gradually change.

So if you’re considering Rejuran at a dermatology clinic near Euljiro 1(il)-ga Station, it’s better to think in terms of

a gradual improvement in your skin’s condition over time rather than an immediately noticeable change.

This is also why treatments are given in multiple sessions at regular intervals.

If you understand how it works before starting treatment at a dermatology clinic near Euljiro 1(il)-ga Station,

you may find it easier to wait and see how things progress, even if you don’t notice a major difference right after treatment^^

2. What factors can affect the results?

If you’ve spent a considerable amount on treatment and waited to see the results, but haven’t noticed the changes you expected, what should you look into?

One factor that can affect the results is where the ingredient is injected.

Cells involved in regeneration are mainly found in the superficial dermis, about 1–2 mm below the skin’s surface.

PN needs to be delivered evenly to this layer to trigger the regeneration signals and begin working as intended.

However, this can be challenging to achieve in practice.

Skin thickness varies from person to person, and even within one person’s face, it differs between areas such as the forehead, cheeks, and around the eyes.

For example, applying the same approach to the thin skin around the eyes as to the cheeks may result in an injection that is too deep or too shallow.

Conversely, if a thicker area is treated in the same way, the PN may not reach the intended layer sufficiently.

Assess the characteristics of each area

and adjust the injection depth

to help deliver PN more evenly to the intended layer.

A study published in 2025 also examined this topic.

The researchers used ultrasound to measure the thickness of 10 areas of the face in 31 patients,

then analyzed which layer the injected PN (Rejuran) reached.

The study found that the dermis beneath the eyes was an average of 0.53 mm thick, while the temples and some areas of the cheeks were about 1.18 mm thick.

The thickness thus varied by nearly twofold across facial areas.

Taking these anatomical differences into account,

the researchers used ultrasound to check whether the PN was reaching the intended dermal layer.

The ultrasound images included in the paper

show that the injected ingredient is distributed relatively evenly throughout the dermis.

The process of delivering

PN to the intended layer

is important, as this study demonstrates.

To sum up the main points of today’s discussion,

it’s important to consider when to assess the effects of Rejuran,

but first, it may be important to determine whether the PN was properly delivered to the intended dermal layer.

Whether or not you understand these differences when you have a consultation

can affect your expectations and satisfaction with the treatment.

If you’re looking for a dermatology clinic near Euljiro 1(il)-ga Station, be sure to ask about the injection placement discussed today.

That’s all for now. I’m Lee Kang-in.
