Nice to meet you.
I’m Lim Jin-young, the chief director of Piap Clinic.
“Songpa Rejuran,
does it really work?”
Honestly, I understand why you’d be worried.
“Everyone around me says it’s good,
but what if it doesn’t suit me?”
“What if I spend the money and don’t notice much change?”
Because of concerns like these,
you may have found it hard to make a decision.
So today, I’m going to explain step by step
how the effects of this procedure actually appear,
and what you need to know
in order to get it properly.

If you can spare about 3 minutes from now,
you’ll be able to check everything
from the mechanism and differences by type
to how to get the full effect.
The key to the effect?
You need to understand the ‘PN ingredient.’
The effect of Songpa Rejuran is not just a vague idea that “you get an injection and feel better.”
The change happens because an ingredient called polynucleotide (PN)
works directly.
PN is a substance made up of DNA fragments,
and it promotes cell regeneration
and helps repair damaged skin tissue.
More specifically, it activates fibroblasts
to increase the production of collagen and elastin,
strengthens the skin barrier function,
and reduces inflammatory responses.

So rather than simply adding moisture or plumping the surface,
it works by boosting the skin’s own recovery ability.
For this reason, changes such as softening fine wrinkles,
improving elasticity, reducing pores,
and refining skin texture can appear.
However, the effect of Songpa Rejuran is not immediate.
Unlike fillers, which create volume right after injection,
this procedure improves the skin gradually over 2 to 4 weeks
as cells slowly regenerate.

So right after the procedure,
you may think, “I’m not sure it’s doing much yet,”
but after about two weeks,
you often start to feel,
“Hmm? Something seems different.”
In the end, the reason the effect appears is that PN acts deep within the skin to induce regeneration,
and although the change is not fast,
it is natural and lasting.
Are all Rejuran products the same?
They differ by type
As mentioned earlier, PN is the key ingredient,
but in actual treatment,
the changes you feel can differ slightly depending on the type.

‘Rejuran Healer’ is the basic type,
composed only of PN.
It aims for regeneration and improved elasticity
across the entire face,
and can help restore the skin barrier
and soften fine wrinkles.
However, because it does not contain hyaluronic acid,
its moisturizing effect is relatively limited.
‘Rejuran I’ is a product designed for thin,
sensitive areas such as around the eyes.
With lower viscosity and higher fluidity,
it is suitable for under-eye fine lines, a sunken appearance,
and improving dark circles.

‘Rejuran HB Plus’ is a type that adds
hyaluronic acid and lidocaine to PN.
So among the effects of Songpa Rejuran,
it suits those who want not only regeneration
but also hydration.
Thanks to lidocaine, pain is also reduced,
which makes it easier to choose for first-time users
or
for people with sensitive skin.
‘Rejuran S’ is a formulation made with
high-concentration PN.
Because it has high viscosity, it is used for intensive treatment of areas with severe damage,
such as deep acne scars,
pronounced wrinkles, or depressed areas.

As you can see, because the application area and purpose differ by formulation,
you need to choose according to your concerns
in order to experience the desired change properly.
To get the effect properly,
be sure to know these <things>.
To fully feel the effects of Songpa Rejuran,
it’s good to understand a few practical points in advance.
First, this is a regenerative procedure.
It is intended to produce relatively natural and gentle changes,
such as restoring elasticity, improving skin texture,
adding moisture, and softening scars.

So if you want dramatic volume increase
or an immediate lifting effect,
Rejuran alone may feel insufficient.
Also, not every skin concern
can be solved by regeneration alone.
Dark circles caused by pigmentation or vascular issues may improve only when laser treatment is combined,
and severe sagging or deep wrinkles may require
considering lifting procedures or radiofrequency treatment as well.
It is also important to understand
that changes take time to appear.

Because collagen and elastin are newly produced,
and the extracellular matrix gradually recovers,
you need to wait about 2 to 4 weeks
to feel real improvement.
So rather than expecting,
“Surely the effect will show right away,”
it’s better to give it some time
and watch for changes in your skin.
Lastly,
Rejuran is not a one-time procedure.
Usually, it needs to be repeated about 3 to 4 times
to maintain stable improvement,
and many people continue maintenance
at intervals of 6 months to 1 year afterward.

In the end, the effects of Songpa Rejuran are certainly worth expecting,
but you need to accurately understand your skin condition,
choose the right formulation,
and maintain it consistently over time
in order to get satisfying results.
So far, we’ve looked at the mechanism behind the effects of Songpa Rejuran,
its characteristics by formulation,
and the practical points you need to know
in order to receive it properly.
This procedure can bring several positive changes,
such as skin regeneration,
restoring elasticity, and adding moisture.
However, since it is not a universal solution
that solves every concern at once,
the first step is to calmly understand
what your skin needs right now.

If your skin needs regeneration,
there may be no better option than this,
but if the cause is something else,
such as pigmentation, sagging, or vascular issues,
you should also consider other methods,
such as lasers or lifting procedures.
In the end, what matters is
understanding your skin accurately,
and keeping an open mind to different possibilities
while finding the most suitable path.
Thank you for reading to the end.
