“Even if I apply moisturizer again and again,

my skin still feels tight inside..”

Some people feel that their skin is rough before and after makeup, and that even after repeatedly applying moisturizer, their skin quickly feels tight.

In these cases, the cause is often not dryness on the surface of the skin, but inner skin dryness (reduced dermal moisturizing ability).

When the skin’s cell regeneration ability declines due to aging, frequent cleansing, skin procedures, or UV exposure, the dermal layer becomes weaker at holding moisture.

At times like this, no matter how good a moisturizer you use, the skin may feel hydrated only briefly before quickly drying out.

One way to fundamentally address this problem is Rejuran Healer.

Today, I’ll talk about how Rejuran Healer can be effective for inner skin dryness.

What causes inner skin dryness?

Moisture in the skin is not maintained only in the epidermis.

Inside the skin’s dermal layer, there is a “moisture storage network” made up of collagen, elastin, and hyaluronic acid.

The stronger this cellular structure is, the less moisture escapes. But when the skin is irritated or aging progresses, this network weakens and moisture evaporates more easily.

Simply put, it’s like “not a water tank, but a leaking pipe.”

That’s why even if you keep adding moisture on the outside, the feeling of dryness inside continues.

What is the role of Rejuran Healer?

The key ingredient in Rejuran Healer is polynucleotide (PN).

This is a biological restorative substance extracted from salmon DNA, and it activates damaged cells inside the skin to induce regeneration and repair.

When PN is injected into the dermis, fibroblasts are stimulated and begin producing collagen, elastin, and hyaluronic acid again.

Through this process, the skin structure becomes firmer, and as a result, a condition is created in which moisture can stay in the skin for longer without escaping.

In other words, Rejuran Healer is “not a treatment that adds moisture, but a treatment that restores the skin structure that allows moisture to stay.”

Thanks to this mechanism, Rejuran can improve inner dryness, fine lines, and dullness at the same time.

What are the treatment effects?

The first thing people notice after Rejuran Healer is that the skin texture becomes smoother and makeup sits less heavily on the skin.

From about 2 to 3 weeks after the treatment, many people say the inner tightness decreases and their skin feels like it is “filling up from within.”

This is due to the process in which the dermal layer inside the skin recovers and moisture slowly builds up.

Usually, after 3 to 4 sessions, people say the skin overall becomes softer and more elastic, and the feeling of moisture lasts longer.

Shinchon Rejuran Healer is not simply a treatment that moisturizes dry skin.

It is a treatment that restores damaged skin structure so the skin can regain its own ability to retain moisture.

It is a method that more fundamentally addresses the cause of inner skin dryness.

That is why many people say their skin feels more moisturized than when they apply moisturizer.

However, if inner skin dryness is severe, it can be more effective when combined with a skin booster that directly injects hyaluronic acid.

So before the procedure, please consult about your skin’s moisture level and overall skin condition first.
