Hello.

I’m Kang In-jeong, the chief director of The River Dermatology Clinic :)

The skin is continuously affected by external stimuli such as ultraviolet rays, friction, and heat,

as well as lifestyle habits that can damage the skin (dietary restriction, excessive sugar intake, lack of sleep, frequent drinking, smoking, etc.)

and the effects of natural aging.

As a result, problems such as reduced skin elasticity, fine lines, roughness, increased sensitivity, and enlarged pores gradually begin to appear.

Today, I’d like to talk about a skin booster that can help improve these problems and restore the skin to a healthier condition,

and among them, the very popular 'Rejuran Healer.'

(You can tell how steadily loved it is by looking at the stock price rise of PharmaResearch, the manufacturer of Rejuran. I’m just sad I don’t own even one share...)

Main ingredient of Rejuran Healer

Rejuran Healer is a treatment that uses polynucleotide (PN), extracted from salmon DNA, as its main ingredient.

PN plays an important role in promoting the cell regeneration process within the skin and helping repair damaged tissue,

and it activates fibroblasts to increase collagen production.

As a result, skin elasticity and moisture are improved, reducing fine lines and enlarged pores.

Various papers also provide data supporting the effects of Rejuran Healer.

In a recently published study, within 4 weeks after Rejuran Healer treatment,

skin moisture increased by an average of 23%, and skin barrier function improved by more than 15%.

This means that the PN ingredient induces the production of collagen and elastin in the dermis,

helping restore the skin’s oil-water balance.

Rejuran Healer, which aims for fundamental skin regeneration

[Dangsan Rejuran]

“Rejuran Healer aims for the fundamental regeneration of the skin.”

One of the biggest strengths of Rejuran Healer is that it directly targets the dermis rather than the skin surface.

One of the questions often asked in the consultation room is whether, within a limited budget, it is better to use expensive skincare products or to receive a skin booster treatment like Rejuran.

Of course, using skincare products that suit each person’s skin condition well is also important,

but general moisturizing creams or sheet masks usually only work on the epidermis, so they are limited to providing temporary hydration.

In contrast, Rejuran Healer has been approved as safe for use as an injectable,

and because it delivers PN by directly injecting it into the dermis, it can work deep within the skin. That is the key difference.

Skin types that can benefit from Rejuran Healer

Rejuran Healer is especially recommended for the following skin conditions!!

Recommended skin type
Skin with severe internal dryness and thinning
Skin bothered by fine lines and enlarged pores
Skin with a weakened barrier and increased sensitivity
Skin damaged by external stimuli and the aging process

The key to Rejuran Healer treatment: precise injection into the dermis

[Dangsan Rejuran]

To maximize the effect of Rejuran Healer, the most important thing is for the PN ingredient to be injected accurately into the dermis.

The dermis is a thin layer about 1–2 mm thick, where proteins that maintain skin elasticity, such as collagen and elastin, are concentrated.

The treatment can show good results only when PN is delivered to this layer.

The raised markings on the skin are the result of the PN being correctly injected into the dermis.

These bumps are an indicator that the PN remains in the dermis,

and although it varies depending on skin type, they naturally subside within 1 to 5 days after the procedure.

I hope the various information about Rejuran Healer I shared today was helpful to you.

If you have any more questions, please feel free to contact us at any time.

Thank you.
