Rejuran Healer,

If you think of it just as a moisturizing injection

and know it that way,

you're half wrong

Q. Rejuran Healer, isn't it ultimately a

hydration injection that makes you moist?

A. It's not moisture replenishment,

but an injection that rebuilds the structure

for the skin to recover on its own.

The fundamental principle is different.

Q. My skin feels very tight from within, but why

don't moisturizing creams or IV drips fix it?

A. Because the cause of inner tightness is not

a lack of moisture, but damage to the skin barrier itself.

"Rejuran Healer, made from PN polynucleotide DNA precursors,

is excellent for firmly rebuilding the damaged

skin barrier and relieving inner tightness."

— Dr. Wi Young-jin (Seoul Beautystone Clinic)

The reason inner tightness

doesn't go away with cream

— it's actually not a moisture

problem

For those who say their face feels tight after washing,

even after trying several moisturizing creams, nothing really changed, right?

This is a bit tricky, because many people

think, "It feels tight because it's lacking moisture,"

but

while that's not completely wrong,

it's an explanation that misses the point.

The real cause of inner tightness is

damage to the skin barrier.

To put it simply, the skin barrier is

the stratum corneum, the outermost layer of the skin,

which holds moisture inside

and blocks external irritation.

When this structure breaks down, no matter how much moisture you add,

it quickly escapes.

Putting cream on top, IV drips, moisturizing ampoules—

they're all "filling it in" methods.

But if the barrier itself is full of holes,

it'll just leak out no matter how much you fill it.

But there's one important thing here.

The ingredient in Rejuran Healer is PN,

that is, polynucleotide.

This is a DNA precursor extracted from salmon,

and DNA precursors are the materials needed

when cells make DNA.

So when this ingredient goes into the skin,

it supplies materials at the cellular level

and promotes cell division and recovery.

It's not simply about adding moisture,

but about creating a structure that rebuilds

the damaged skin barrier.

Once the barrier becomes strong again,

that's when moisture is naturally retained.

That's when inner tightness is truly relieved, too.

To be honest, even I only truly felt that Rejuran was

different after using it in various cases

and realizing, "Ah, this is completely different

from simple moisturizing in mechanism."

It's not just that the skin feels moist right after the procedure,

but over 2 to 4 weeks, the skin texture itself

changes.

👨‍⚕️ Dr. Wi Young-jin's key summary

The PN ingredient in Rejuran Healer

does not supply moisture itself.

It directly supplies the materials

for cells to regenerate from within the skin,

guiding the damaged skin barrier to recover

on its own.

That's why it's especially suitable for barrier issues such as

inner tightness, dryness, and uneven skin texture.

So for whom

has it actually been effective?

It depends on the case,

but this is usually how I look at it.

The people Rejuran Healer suits best

fall into three broad types.

The first are those whose skin barrier

has been repeatedly irritated.

People who have had lasers or peels frequently,

those who have maintained a strong skincare routine for a long time,

or those who have been exposed for a long time to

dry seasons or environments.

In these cases, the barrier is chronically thinned, so

if you induce cell regeneration with PN ingredients,

the response tends to be good.

In our cases as well, many people who said, "I had

several moisturizing treatments elsewhere, but they didn't do much"

reported that their inner tightness

clearly decreased after 2 to 3 Rejuran sessions.

The second are those with uneven skin tone and texture.

Not a pigmentation issue, but the skin somehow

looks dull,

with rough texture or more noticeable pores.

As the PN ingredient promotes cell regeneration,

it helps refine the skin texture.

The third are those who are starting

to worry about early fine lines.

This is a point many people misunderstand,

but Rejuran is not a filler that fills in deep wrinkles.

It works in the direction of gradually improving the skin's thickness itself

to create skin that develops fewer fine lines.

That's why many people start it in their early to mid-30s

for preventive purposes.

But it's not all good, either.

PN-based procedures do not show effects quickly.

If you come expecting dramatic changes right after the procedure,

you may be disappointed.

Usually, from about two weeks on,

you start to feel the skin changing little by little,

and the results become clear after 3 to 4 sessions.

However, because that effect is created from your own skin cells,

the duration tends to be relatively longer

than procedures that simply fill things in.

This is a procedure suited more for people who want to change the overall quality of their skin

than for those who want quick changes.

Frequently Asked Questions

Q1. Rejuran Healer—does it cause a lot of swelling or bruising?

A. It varies from person to person.

Rejuran is injected evenly across the skin

using fine needles, so redness and tiny dot-like marks

usually appear right after the procedure.

They usually subside the same day or by the next day.

Bruising depends on the case,

but people with strong circulation or certain areas (such as under the eyes)

can bruise.

It usually fades within a week,

and stopping blood-thinning ingredients such as aspirin or vitamin E

a few days before the procedure

can help.

If you have an important appointment on the day of the procedure,

please let us know in advance,

because it's better to adjust the schedule accordingly.

Q2. What's the difference between Rejuran Healer and a water-glow injection?

A. Honestly,

this is something many people get confused about.

A water-glow injection is a method of directly filling the skin

with hyaluronic acid (a moisturizing ingredient).

It gives you an immediate moist, glowing effect right after the procedure,

but once the filled-in ingredient breaks down,

it returns to its original state.

Rejuran Healer is a method that induces cell regeneration itself

with PN ingredients.

The immediate effect after treatment is not as dramatic as a water-glow injection,

but as treatments accumulate, the skin structure changes.

In short, a water-glow injection is for immediate radiance,

while Rejuran Healer is for fundamentally changing skin quality—

they're different procedures with different goals.
