Check the Key Points for Care Before and After the Procedure

Mokdong Rejuran

Hello.

I’m Kim Jin-hyeon, the chief director at You&I Clinic Mokdong Branch.

"I’m curious about what kind of procedure Mokdong Rejuran is."

"I’m worried about the pain that can occur during the procedure."

Many people feel stressed every time they look in the mirror because their skin texture has become dull and dry.

When moisture in the skin dries out and a cycle of reduced elasticity continues, many begin seriously considering Rejuran as a fundamental solution.

Before undergoing the procedure, it is often difficult to predict exactly when changes will appear or how long the effects will last, so many people hesitate.

So today, I’d like to talk about what Rejuran does inside the skin and what criteria you should consider when approaching it.

Mokdong Rejuran

What kind of procedure is it?

Rejuran is a type of skin booster that helps fill damaged and thinned skin from within, enhancing the skin’s natural regenerative ability.

The key ingredient in this procedure is PN (polynucleotide). It is a DNA fragment extracted and purified from salmon, and it is highly compatible with the human body because it is very similar to the human genetic base sequence.

When this ingredient is delivered to the dry and thinned dermal layer, the activity of fibroblasts within the skin becomes active again.

Fibroblasts are key cells that produce collagen and elastin, which support our skin.

As cells whose function had declined begin to do their job again, the thinned skin layer can become more organized and elasticity may gradually be restored.

However, because the principle is to help the skin tissue recover on its own, changes tend to appear gradually and naturally.

Rather than forcing rapid changes, a more realistic approach is to watch the skin environment stabilize at the pace of your own skin regeneration.

What changes can you expect?

Rejuran helps improve a weakened skin barrier and builds the skin’s ability to protect itself from external irritation.

Because the active ingredients increase the density of the dermal layer, positive changes can be expected if your skin is naturally thin or easily turns red even with small temperature changes.

In addition, as the skin environment is adjusted, excessive sebum secretion may be reduced and chronic inner dryness may improve.

For those with combination skin that feels dry inside but oily on the surface, or for people whose skin flakes severely every time the seasons change, this can be a suitable way to balance oil and moisture.

Of course, it is difficult to expect every concern to be perfectly resolved with just one procedure.

This is because skin thickness and the degree of damage vary from person to person.

Therefore, after carefully checking the current condition, it is important to set the necessary number of sessions and intervals and gradually improve the skin environment.

Key points to check

One of the main reasons many people hesitate to undergo the procedure is concern about the irritation and pain that can occur during treatment.

Since Rejuran must deliver its active ingredients directly into the dermal layer, some stinging is unavoidable.

However, if numbing ointment is applied carefully and for enough time before the procedure, the discomfort felt during treatment can be reduced.

Sensitivity to irritation can vary greatly from person to person, so it is a good idea to consider your own pain sensitivity in advance.

If you are especially sensitive to irritation or need treatment over a large area, you may also want to consider an alternative such as sleep anesthesia to reduce the burden.

Above all, the most important thing is to first check your current skin condition through precise diagnostic equipment.

Rather than undergoing treatment unconditionally, the process of consulting thoroughly with an experienced medical team and establishing a care plan that suits you should come first.

Today, I have shared the information that would be helpful for those who are concerned about Mokdong Rejuran.

Mokdong Rejuran is a process that helps the skin’s natural regenerative ability, but the degree of change you feel may vary depending on each person’s skin thickness and condition.

Even for the same procedure, the intensity and interval may differ, so after checking your condition, I recommend making a plan that fits your skin.

This has been Kim Jin-hyeon, chief director of You&I Clinic Mokdong Branch.

Thank you.
