“Why do wrinkles form so easily around the eyes..?”

The skin around the eyes

is the thinnest skin on the face.

It has almost no sebaceous glands,

and because it moves hundreds of times a day,

wrinkles appear right away when the skin is dry or tired.

Many people worry because wrinkles form easily

but do not go away easily either.

There are several different procedures

that can help reduce under-eye wrinkles.

Today, among them,

I’ll talk about Rejuran,

a method that helps the skin recover on its own.

We’ll also look at actual clinical study results,

so if you’re curious about how effective it is,

reading to the end may be helpful.

Yeongdeungpo Rejuran

The key ingredient in Rejuran is

polynucleotide (PN),

that is, a biomaterial extracted from salmon DNA.

This ingredient reactivates damaged cells

in the dermis layer

and promotes the production of collagen and elastin.

As a result, the skin

regains firmness and thickness on its own.

Especially in thin and sensitive areas like the eye area,

PN stimulates cells in the dermis layer,

allowing the skin texture, elasticity, and moisture retention

to recover at the same time.

In a study published in a journal in 2022,

Rejuran was injected into the wrinkle area around the eyes,

and the results measured through 3D skin imaging

were as follows.

[ Research Results ]

  • 6 months after the procedure, skin thickness increased by

an average of 0.32~0.4 mm

  • Fine wrinkle depth decreased by about 25~35%

  • Collagen rearrangement and increased neovascularization

The researchers concluded that “PN promotes a physiological regenerative response in the dermis layer without heat or filler expansion.”

In actual clinics as well,

after 3 to 4 sessions of Rejuran,

“I can see less hollowness under my eyes,

and the fine wrinkles have softened.”

“The makeup doesn’t settle as much into the wrinkles around my eyes.”

These are comments we often hear.

In other words, many people could actually feel the change in their skin from the “increase in skin thickness” measured in the study.

  1. ‘Rejuran i’ for the eye area

Because the eye area has a thinner and more sensitive skin layer than other areas,

the finer-particle Rejuran i product is used.

This product is designed for the upper dermis layer,

and its formulation is more fluid.

The existing Rejuran Healer

has a relatively high viscosity,

so after the procedure it takes longer to spread within the skin,

which could cause temporary raised bumps.

Since the eye area has thin and sensitive skin,

the viscosity is made more fluid so it can spread

more smoothly within the skin.

When the viscosity is thinner, there is less pain during the procedure,

and there is also less bruising or swelling afterward,

which has the advantage of faster recovery.

If you receive 3 to 4 sessions at 2 to 3 week intervals,

you can see improvements such as more refined skin texture

and less visible fine wrinkles.

Today, we looked at what effects you can expect

when receiving the Yeongdeungpo Rejuran procedure.

Rejuran is not simply

a procedure that smooths out wrinkles.

It is a treatment that enhances the skin’s regenerative ability

so that the skin can restore a healthy structure on its own.

If you use Rejuran i, the product for the eye area,

it can be applied safely even to the thin skin around the eyes,

so I hope this helps those who are usually concerned about under-eye wrinkles.
