will tell you the “decisive difference”

Hello.

This is Obje Plastic Surgery.

As we get older,

the reason our face starts to look different

is not just because of one wrinkle.

As the volume inside the skin decreases,

and the support structure weakens,

the overall impression often

slowly falls apart.

Because of this, recently,

it is not simply fillers or lifting

that are drawing attention,

but procedures that aim to

restore both skin regeneration and volume

at the same time.

In that process,

the procedures most often compared are

Rejuran and Rejuto.

Both procedures

aim for natural-looking changes,

but their mechanisms and areas of application

are quite different.

In particular, with Rejuran,

there has even been talk that it is difficult

to undergo the procedure in Korea,

which has led many people to wonder,

“Then what is the alternative?”

Today, for those who are

trying to decide between Rejuran and Rejuto,

I will organize the similarities and differences

between the two procedures,

as well as practical decision-making criteria.

If you read to the end,

you will be able to judge for yourself

which choice is more reasonable

for your current situation.

What do Rejuran and Rejuto have in common?

In fact, the “core” is the same.

Both Rejuran and Rejuto

fundamentally follow the same principle

in that they use a component called “ECM.”

ECM is also called the extracellular matrix,

and simply put, it plays the role

of a framework that supports skin tissue.

Inside this framework,

key proteins such as collagen and elastin

are tightly interwoven and are responsible

for the skin’s elasticity and thickness.

As we age, this framework breaks down,

which causes the skin to become thinner

and sag.

Rejuran and Rejuto work by

rebuilding this collapsed framework.

Rather than simply adding volume

like a conventional filler,

they reconstruct the skin tissue itself,

which is why

both procedures can be expected to have

fundamental anti-aging effects.

They also have the advantage of

a short procedure time and relatively quick recovery,

which is why many people are interested in them.

What is the difference between Rejuran and Rejuto?

It lies in the “source of the ECM.”

Then why are these two procedures

discussed separately if the principle is the same?

The decisive difference comes from

“where the ECM is extracted from.”

Rejuran uses ECM made by refining

adipose tissue from cadavers.

It is produced by removing the cells

from cadaveric fat and leaving only

the protein structure behind.

Rejuto uses ECM extracted

from donated dermis.

The dermis is a key layer that directly determines

skin thickness, elasticity, and density,

and it is also a structure that is among the first

to be affected by skin aging.

For this reason, ECM derived from the dermis

focuses on creating an environment

that supports the skin’s own structure.

On the other hand, ECM derived from adipose tissue,

which is used in Rejuran, reflects the characteristics

of soft tissue and is closer to serving as a matrix

that cushions volume and gently supports tissue space.

In other words, while Rejuran and Rejuto are both

ECM-based procedures,

Rejuran can be interpreted as focusing more on

improving the soft-tissue and volume environment,

whereas Rejuto is more directly focused on

improving the firmness of skin structure

and dermal density.

Because of these differences,

when the skin has become thinner and overall

elasticity has declined,

Rejuto, which uses dermis-derived ECM,

is often considered the more suitable option.

Where can you receive Rejuran and Rejuto?

Overseas vs. Korea

Another difference that should not be overlooked is

“where you can receive it.”

Rejuran has received FDA approval in the United States,

but it has not yet received official approval in Korea,

so it is difficult to undergo the procedure here.

Since it is only available at some overseas clinics,

getting the procedure means dealing with the hassle

of traveling abroad,

and the cost burden is not small either.

By contrast, Rejuto is available in Korea.

After consulting with a board-certified plastic surgeon,

the procedure can even be performed on the same day,

so it is much more accessible.

In the end, if you are expecting the same effect,

there is a choice that can be received more safely

and conveniently.

If you have read this far,

the similarities and differences between Rejuran and Rejuto

should be a little clearer.

Both procedures use ECM

to rebuild skin tissue, so in that sense they are the same,

but

when you look at the source of the material

and the accessibility,

Rejuto can be a much more reasonable choice.

Most of all, the fact that you can experience

verified results safely without going overseas,

and that you can receive a customized procedure

that matches your skin condition

through sufficient consultation with a domestic specialist,

is Rejuto’s biggest strength.

However, whichever procedure you choose,

what matters most is accurately determining

whether it is right for you.

Skin thickness, elasticity,

and the areas you want to improve

must all be considered together

to achieve a result without regrets.

If you are wondering whether Rejuto is right for you,

I recommend getting an accurate diagnosis

through professional consultation.

Director Park Si-hyeon of Obje Plastic Surgery

carefully reviews the source of the material,

the refining process, and the mechanism of action

inside the skin,

and then carefully determines the areas and extent

that require treatment based on the patient’s

skin thickness, elasticity,

and pattern of aging.

In addition, for all anti-aging procedures,

we avoid excessive changes,

and we consider results that do not look unnatural

even as time passes

to be the most important standard.

We hope the information explained today

helps you make a wise choice,

and

we cheer you on as you build a more resilient skin

and a more energetic daily life.

This has been Obje Plastic Surgery.

Thank you.
