Is there a way to get it with less pain?
Mok-dong Rejuran
Hello.
I’m Kim Jin-hyun, the chief director of UNNI Clinic Mok-dong.

"I’ve heard it hurts a lot.
Will it suit my skin?"
Because there are so many types of skin boosters, many people find it difficult to judge which treatment is right for them.
People often say, "My friend got it and said it improved so much, so I came too, but I’m scared it might hurt too much," expressing both expectations for the effects and concerns about pain at the same time.
Just because something is well-known does not mean it can be the "right answer" for everyone.
Today, I’d like to carefully explain the principles of Mok-dong Rejuran, ways to reduce the burden of pain, and the key points you should check before treatment.

What kind of treatment is it?
First, you need to understand how this treatment works within the skin.
The main ingredient in Rejuran is polynucleotide (PN).

This is a substance extracted from salmon DNA, and because it has high compatibility with the human body, there is relatively less concern about adverse reactions.
When this ingredient is delivered into the dermis layer of the skin, it helps activate fibroblasts.
Fibroblasts are cells that create collagen and elastin, which are responsible for our skin’s elasticity, almost like a kind of "factory."
As we age or are exposed to external刺激, this factory works less, leading to reduced elasticity and the formation of wrinkles.

At this point, the PN ingredient goes in and wakes up the tired fibroblasts, getting them working again.
Rather than simply filling the surface temporarily, you can think of it as a method that supports the skin’s natural regenerative ability.
Thanks to this, you can expect a stronger skin barrier and improved oil-moisture balance.

In particular, for the eye area where the skin is thin and fine lines are many, a carefully adjusted version called Rejuran I is sometimes used.

What about the pain?
Some of you reading this may also be hesitating because of the pain.
To be honest, the basic Rejuran Healer has relatively large particles and high viscosity, so some pain can accompany the injection.
However, as technology has advanced, methods that address this discomfort have appeared. One of them is Rejuran HB Plus.

This product contains lidocaine, a local anesthetic, in the existing formulation, which may help reduce the pain burden felt during the procedure.
In addition, hyaluronic acid (HA) is added, so it can have a positive effect not only on regeneration but also on improving hydration.
In practice, when recommended to people who are sensitive to pain, I often hear that it felt more comfortable than before.
Of course, the degree felt can vary from person to person.
Methods such as adjusting the application time of the numbing cream or combining the procedure with soothing care are also available, so it is best to let the medical staff know your sensitivity to pain in advance.

Be sure to check before treatment
What you should pay attention to here is whether, no matter how good the ingredient is, it is the right timing for your skin.
You should avoid insisting on the same procedure just because someone around you saw results.

For example, if your main concerns are already deeply set wrinkles or sagging, a filler or laser lifting device may be a more efficient alternative than a skin booster.
On the other hand, if the skin as a whole is thin and dry, and fine lines are the concern, Rejuran may be a suitable choice.
Sometimes, sufficient moisturizing care or changes in lifestyle habits should come first rather than a procedure.
That is why it is important to carefully check the current condition of the skin layers and the depth of the lesion through a precise diagnostic device such as Markview, and to establish a plan after thorough consultation with the medical staff.
Today, I summarized the points that many people who came in searching for Mok-dong Rejuran are curious about.

There are various ways to reduce the burden of pain, but you should remember that differences may occur depending on an individual’s skin thickness and sensitivity.
Therefore, I recommend that you 반드시 find the method that suits you based on a careful diagnosis before the procedure.
