Hello.
This is Beauty S Doctor Kim Jang-ju.
If you are concerned about healthy skin,
you may have heard of at least one procedure
often mentioned in dermatology clinics these days.
It is Rejuran Healer,
also known as the “salmon injection.”
As the name suggests, this treatment is
based on PN (Polynucleotide) ingredients
derived from salmon,
which is why it naturally earned the nickname
“salmon injection.”
Unlike general moisture-focused skin treatments,
it does not simply make the skin surface
feel hydrated.
It focuses on restoring damaged tissue
inside the skin and normalizing
the overall environment that has weakened.
In addition to Healer,
Rejuran also comes in various lineups such as
I, HB, and S,
which are applied slightly differently
depending on a person’s skin condition
or treatment area.
Although the names may seem similar,
in actual clinical practice,
each has a clearly different role and purpose.
Among them, the most basic treatment is
what we commonly call Rejuran Healer,
that is, the salmon injection.

Salmon injection effects
“Lately, my skin has lost its glow.”
This is one of the most common things
I hear in the consultation room.
The reason people look for Rejuran Healer
also usually starts with this change in “glow.”
In fact, after treatment,
many people feel that even after just one session,
their skin texture becomes more refined
and they get a subtle radiance.
This is because the PN ingredient works inside the skin
and stabilizes regeneration
and moisture balance at the same time.
In other words, it does not simply moisturize;
it works in a way that restores
the skin environment itself.
The representative changes you may expect are:
✔️ Softening of fine lines
✔️ Recovery of a thinned skin layer
✔️ Improvement of enlarged pores
✔️ Smoothing of rough skin texture
✔️ Relief from inner dryness
✔️ Increased elasticity and improved skin density
✔️ Strengthening of the skin barrier and calming of inflammation
In particular, the salmon injection effect
is easier to notice in situations such as:
✔️ Skin with recurring acne
✔️ Skin that has become thinner and more sensitive
✔️ Skin with ongoing inflammatory responses
In these cases,
it can help stabilize the skin condition
and support recovery of overall balance.
In the beginning,
the skin may first appear calmer
and develop a glow,
and over time,
this can lead to gradual improvements
in skin density and elasticity.
Rejuran Healer effect duration
Salmon injection interval
At first, it is better to understand it as a process
where the skin texture changes,
and later, elasticity begins to build.
Rejuran Healer is generally recommended
a total of 3 to 4 sessions
at 2- to 4-week intervals.
After that,
maintenance treatments are often done
about once every 6 months to 1 year.
At the beginning,
you may notice changes in skin texture and glow
relatively quickly,
but structural changes that are visible,
such as elasticity or skin density,
usually appear gradually
after the second or third session.
In other words, this is not a one-time effect;
you should think of it as a treatment
that is completed through accumulation.
Depending on an individual’s skin condition and purpose,
the interval and number of sessions can be adjusted,
and within a consistent salmon injection schedule,
the key is to build up the skin’s basic resilience.
Are side effects something to worry about?
Rejuran Healer is a injection treatment
that induces skin regeneration,
so temporary reactions may occur.
Typical reactions may include:
✔️ Embossing effect
(a bumpy raised appearance at the injection site)
✔️ Minor bruising
✔️ Redness
✔️ Mild pain when pressed
The embossing effect is a natural reaction
that appears as the injected PN ingredient settles in,
and in most cases it subsides naturally
within 1 to 3 days.
Bruising and redness also vary from person to person,
but they are usually not severe enough
to interfere with daily life
and can be covered with makeup.
There are also things to be careful about.
✔️ Pressing or massaging with your hands
to try to remove the embossing
✔️ Drinking alcohol, going to a sauna,
or doing intense exercise right after treatment
These actions can interfere with the recovery process,
so it is better to avoid them.
Overall,
Rejuran Healer uses PN ingredients
that are friendly to the human body,
so it is known as a treatment
with a relatively low risk of side effects.

Recommended for people like this


Rejuran Healer is not a treatment
that improves only a specific area,
but one that aims to rebalance
the overall condition of the skin.
Therefore, it may be more suitable if you have concerns such as:
✔️ Skin texture has become rough and the glow has disappeared
✔️ Skin with severe inner dryness and tightness after washing
✔️ Wanting to recover skin that has become thin and sensitive
✔️ Skin with recurring breakouts or inflammation
✔️ Fine lines around the eyes or mouth that are bothersome
Recently,
if you feel that your skin condition is not what it used to be,
or if you feel like your skin is generally falling apart,
it may be worth approaching it from the perspective of
“recovery” rather than simple care.
Rejuran Healer is not a treatment
that decorates the outer skin;
it is closer to a method of filling it back up
from within.
Rather than a dramatic change,
its 특징 is creating a gradual improvement flow
that builds over time.
In the end, what matters is not a quick change,
but building a foundation of skin
that does not fall apart.
The strength of skin built up steadily,
in line with the salmon injection schedule,
can make starting with Rejuran Healer
a good choice.
Thank you for reading.
