Treatments known as skin boosters,
such as Rejuran, Juvelook, and Skin Botox,
are probably familiar names to many people by now.

 

In comparison,
Elravie Re2O is still not a name that is widely familiar to the general public.

 

That is why, during consultations,
many people ask questions like,

“Is it similar to Rejuran?”
“Does it stimulate collagen like Juvelook?”
“Does it fill the skin like filler?”

 

Today, I would like to explain how Re2O can be understood,
and how changes in skin density, volume, and tissue structure were observed
in related study data, using the photos and graphs above :)

The key point of Elravie Re2O
is connected to the dermal environment inside the skin,
especially the concept of the extracellular matrix, or ECM.

 

Simply put, ECM is like the “inner foundation structure” of the skin
that helps collagen, elastin, and various structural proteins
stay in place and maintain support.

 

If we compare it to a house,
cosmetics or a temporary sense of hydration are closer to wallpaper or paint,
while the ECM structure of the dermis is closer to the framework inside the wall.

 

So Re2O is not really a filler that immediately creates a large volume effect.

Rather, it can be explained as a treatment that approaches concerns such as skin texture, fine wrinkles, skin density, and decreased elasticity
in a more structural way.

If you look at the graph above,
the study observed changes in skin density at Baseline, 4 weeks, 8 weeks, 12 weeks, 16 weeks, and 20 weeks.

 

The image above shows the captured skin density images,
and the graph below summarizes the numerical changes.

 

When comparing the Test group and the Control group,
you can see that the skin density index increased over time.

 

In particular, at 12, 16, and 20 weeks,
the Test group showed a larger degree of change.

 

To explain this more simply to patients,
this data did not only check whether the skin looked hydrated on the surface.

It also evaluated how the density inside the skin changed when measured with a device.

 

Of course, just because the graph improved,
it does not mean that everyone will experience the exact same change.

 

Results may vary depending on skin thickness, age, dryness, inflammatory response, treatment interval, injection depth, and other factors.

 

Still, at least in this data,
we can see that the phADM-based approach is being studied in relation to changes in skin density.

The photo above shows data evaluating changes in skin volume.

 

At the top, there are images captured using a 3D device,
and at the bottom, changes in skin volume values are shown in a graph.

 

The important point here is that the word “volume”

should not be understood only as something that enlarges a specific area,
like filler.

 

The volume change described in this study is better understood as a change where the skin surface and dermal environment appear slightly more filled and dense.

 

In other words,
it is not filler-like volume that lifts the nasolabial folds all at once.

Rather, it is a type of volume that comes from the skin foundation becoming somewhat firmer
and the surface appearing less dry or rough.

If you look at the tissue image above,
the content becomes a little more technical.

 

You can see terms such as H&E staining, SEM,
and fibroblast incorporation rate.

 

To put it simply,
this data observed how phADM appeared within the skin tissue under a microscope,

and how much fibroblast incorporation was seen.

 

Fibroblasts are cells closely related to collagen and various matrix components inside the skin.

 

So this part can be understood as data showing the possibility
that the material does not simply disappear like water inside the skin,
but may interact with the dermal environment.

 

Of course, it would be excessive to look at this image and say,

“the skin completely regenerates,”

or
“new tissue is always created.”

 

It is more appropriate to explain this cautiously as
histologic changes related to the dermal environment being observed.

In the explanation above,
there is also content related to changes in pigmentation area and erythema, meaning redness.

 

The study evaluated changes in pigmentation area and erythema over 20 weeks.

 

What is interesting is that the researchers did not only look at skin density and volume,
but also evaluated skin tone-related indicators such as pigmentation and redness.

 

However, this part needs to be interpreted very carefully.

 

Re2O should not be described as

“a melasma treatment”
or
“a redness treatment.”

 

Pigmentation and redness are influenced by many factors,
including UV exposure, inflammation, vascular response, skin barrier condition, and hormones.

 

That said,
when the skin barrier and dermal environment become more stable,
the skin may appear less sensitive overall,
or the surface condition may look more refined to some extent.

 

So it is safer to interpret this data not as
“direct treatment of pigmentation or redness,”
but as “additional indicators observed alongside changes in the skin environment.”

 

Then who may be a good candidate for Re2O?

 

Personally, I think it can be explained well for people who have
thin and dry-looking skin,
visible pores and fine wrinkles together,
those who felt that ordinary skin boosters only gave a temporary hydration effect,
or those who feel burdened by the idea of filler-like volume.

 

On the other hand,
if deep nasolabial folds, clear volume loss,
or sagging of the facial contour are the main concerns,
Re2O alone may not be enough.

 

In such cases,
filler, lifting treatments, radiofrequency, lasers, collagen boosters, and other treatments
may need to be designed together according to the skin condition and facial structure.

 

In the end, even when people say,
“my skin does not look good,”
the actual cause can be different.

 

For some people, the issue may be lack of hydration.

For others, it may be pores and skin texture.
For others, it may be decreased dermal density and elasticity.

And for some, pigmentation or redness may be the bigger concern.

 

So to properly understand the effects of Re2O,
it is important not to look at the product alone.
The first step is to identify what direction of recovery your skin actually needs.

 

To summarize,
Elravie Re2O is not yet as widely known as Rejuran or Juvelook,
but it is a skin booster-type treatment that can be explained around the concept of the dermal environment and ECM inside the skin.

 

What matters here is determining whether your skin needs hydration support,
collagen stimulation, reinforcement of the dermal environment,
or whether lifting or volume design should come first.

 

Choosing a good product is important,
but what matters even more is designing it properly
so that the product is used in a direction that suits your skin :)
