Hello.
I’m Beauty’s Doctor, Wi Youngjin.
There are moments when you feel that your skin’s elasticity is not what it used to be.
At times like this, many people start considering collagen injections or skin booster procedures.
In particular, more and more attention has recently been paid not just to methods that stimulate the skin and induce regeneration, but to procedures that directly replenish the ingredients the skin needs.
Today, among those options, I’ll explain in a little more detail a procedure that directly replenishes collagen,
Rejuran.

Changes That Occur When Skin Collagen Decreases
As we age,
collagen in the skin gradually decreases.
Collagen is a key structural protein that maintains the skin’s elasticity and density.
When its amount decreases,
the skin shows several changes.
• Pores appear larger
• Skin texture becomes rougher
• Fine lines increase
• Skin dries out more easily
• Overall elasticity declines
That is why many people try to restore skin density through collagen injections or booster procedures.
In fact,
among patients visiting the Gongdeok dermatology clinic,
there is a growing number of inquiries about collagen-related procedures to improve pores and elasticity.
What Makes Rejuran Different

Rejuran is somewhat different in concept from conventional collagen injections.
Rather than simply inducing skin regeneration,
it is a procedure that directly injects highly purified animal-derived collagen into the skin.
In other words,
instead of waiting for collagen to be produced,
it is a method that immediately replenishes the collagen that is lacking.
Because of this,
it has the following characteristics.
• Moisture is felt immediately after the procedure
• Skin elasticity improves quickly
• Helps refine pores and skin texture
• Relatively consistent results can be expected
Recently,
in consultations at the Gongdeok dermatology clinic,
we often hear questions such as,
“Is there a procedure that makes the skin feel hydrated right away?”
One of the procedures we explain in such cases is
Rejuran.
Key Features of the Rejuran Procedure
The biggest advantage of Rejuran is
its immediate, noticeable change.
Because collagen is injected directly into the skin,
many people feel the following right after the procedure.
• The skin feels more hydrated
• The skin texture feels smoother
• The skin feels firmer and more elastic
As time passes afterward,
the injected collagen
naturally blends with the skin tissue.
In that process,
the effect of improving skin density
progressively continues.
In other words,
immediate hydration + gradual elasticity improvement
these two effects
appear together.
That is why,
after consultation at the Gongdeok dermatology clinic,
it is often introduced as one of the options for people concerned about improving skin texture or pores.
Areas Where the Effect Is More Noticeable
Rejuran
is especially noticeable in areas where the skin is thin and elasticity has declined.
Typical areas include the following.
✔ Cheeks where enlarged pores are a concern
✔ The eye area where fine lines easily form
✔ Fine lines around the mouth
✔ The jawline with reduced elasticity
✔ The entire face where skin texture has become rough
In particular,
it is one of the procedures with high satisfaction because it can be expected to improve both pores and skin texture at the same time.
In actual consultations at the Gongdeok dermatology clinic,
concerns about pores, skin texture, and elasticity often appear together.
It is often suitable for people with these combined concerns.
When Changes Appear After the Procedure

With Rejuran,
a feeling of hydration may be noticeable immediately after the procedure.
However,
skin changes appear gradually.
A rough timeline is as follows:
Immediately after the procedure
A feeling of hydration and improved skin texture
After 2–4 weeks
Increased skin density and refined pores
Around one month later
The most natural improvement in elasticity
Through this process,
the skin condition gradually stabilizes,
leading to a healthier skin state.
That is why,
at the Gongdeok dermatology clinic as well,
a planned treatment approach tailored to the skin condition is recommended rather than a one-time procedure.
Recommended Treatment Interval
Even one session of Rejuran can make many people feel more hydrated and elastic skin.
However,
for more stable changes,
the following schedule is recommended.
Initial care
3 sessions at 3–4 week intervals
Maintenance care
Every 3–6 months
If done this way,
skin density and elasticity can be maintained more stably.
Because the treatment plan may differ depending on skin condition,
it is important to receive a consultation tailored to your individual skin state during a visit to the Gongdeok dermatology clinic.
Pain and Recovery Process

Rejuran is a method of injecting collagen using a fine needle.
Therefore,
some pain may occur.
However,
because numbing cream is used,
most people undergo the procedure without much discomfort.
After the procedure,
• temporary swelling
• redness
• bruising
• a slightly uneven feeling
may occur.
In most cases,
these improve naturally within 2–5 days.
However, because the skin is more sensitive after the procedure,
it is best to avoid saunas, strenuous exercise, and strong UV exposure for about 3–5 days.
Key Summary
✔ Rejuran is a procedure that directly injects collagen.
✔ You can feel hydration and elasticity immediately after the procedure.
✔ It helps improve pores, skin texture, and fine lines.
✔ An initial course of 3 treatments at 3–4 week intervals is recommended.
✔ After that, maintenance every 3–6 months is good.
Skin procedures are not just about choosing a trendy treatment.
It is important to find the method that matches your current skin condition and goals.
Rejuran can be especially helpful in cases where
the skin has become dry,
elasticity has declined,
or pores and skin texture are a concern.
However,
because it does not apply equally to all skin types,
it is necessary to confirm through sufficient consultation whether it is the right procedure for you.
Planned care suited to your skin condition
can create the most natural and healthy results.
Thank you for reading this long post.
