'Rejuran works really well,

Is there any way to reduce the pain?'
Rejuran is a representative skin booster that many people seek out for its skin regeneration and recovery effects.
It is especially popular because it helps improve damaged skin and restore elasticity. ^^
That is why various types have been released, allowing each person to choose one that suits their skin condition.
However, because many people report pain during the procedure, understanding this and knowing how to manage it is also important.
Today, we will look at Rejuran’s ingredients and principles, the features of each type, and ways to reduce pain.

Jamsil Rejuran
Ingredients, principles, and expected effects
The key ingredient in Rejuran is polynucleotide (PN) extracted from salmon DNA.
PN helps promote skin cell regeneration and repair damaged DNA.
When PN is injected into the dermis, it activates cells and induces collagen production, which can help strengthen skin elasticity, improve fine lines, and restore the skin barrier.
It also has a positive effect on improving skin tone and reducing inflammation, helping overall skin health. ^^

Comparison of 4 types
Rejuran is broadly divided into four types.
- Rejuran Healer

Rejuran Healer can be thought of as the original Rejuran. ^^
It contains PN 20mg/cc, so it is good for skin regeneration and damage repair, making it suitable for overall skin improvement.
- Rejuran HB plus

Rejuran HB is characterized by containing PN 10mg/cc, hyaluronic acid, and lidocaine.
Thanks to hyaluronic acid, you can expect both skin regeneration and moisturizing effects, and because it contains lidocaine, a local anesthetic, it also helps reduce pain.
Therefore, it is suitable for sensitive and dry skin. ^^
- Rejuran S

Rejuran S is a product with a low PN concentration to minimize skin irritation, and like HB PLUS, it contains hyaluronic acid.
It is recommended for improving acne scars or for areas with extremely sensitive skin. ^^
- Rejuran I

Rejuran I is a gentle formulation specialized for improving eye-area wrinkles and dark circles.
So it can be chosen when you want Rejuran applied to delicate areas such as around the eyes.
It is also effective for improving elasticity and skin tone. ^^
In this way, Rejuran has different ingredients and characteristics depending on the type, so it is necessary to choose one that matches your skin type and purpose.
Therefore, we recommend consulting with a medical professional in advance to choose the right product for you!

Causes of pain and how to reduce it
If you look through reviews, there are many comments mentioning Rejuran pain. ^^;;
Why exactly is Rejuran so painful?
The causes of pain can be broadly summarized into two points.
-
Physical stimulation from the injection needle
-
Pressure and expansion when the medication is injected

First, let’s look at the physical stimulation from the injection needle.
Our skin has various nerve endings distributed throughout it, so irritation occurs when the needle passes through the epidermis and dermis.
This makes the pain feel stronger.
However, this can be reduced to some extent with anesthetic cream, and for most people, the pain comes less from the needle itself and more from the pressure created during drug injection.
Edema effect
When the medication is injected into the skin, the tissue expands depending on the medication’s viscosity and the injection speed.
Then pressure is applied, which can cause severe pain.
In particular, pain may be felt more strongly in areas with thin or sensitive skin, or when the injection speed is fast.
However, please keep in mind that individual skin condition and pain threshold differ, so even with the same procedure, the intensity of pain may be felt differently!

Now, let me tell you how to reduce pain.
For irritation caused by the injection needle, as mentioned earlier, one method is to apply a local anesthetic cream before the procedure.
If you are very sensitive to pain, receiving treatment with Rejuran HB plus instead of Rejuran Healer could also be an option.

In the case of pressure pain, medical staff can reduce discomfort by carefully adjusting the injection speed and depth.
Using a device such as an injector instead of manual injections can also be a way to make the injected amount more uniform.
And immediately after the procedure, it is also good to use a cold compress or cooling device to relieve warmth and swelling.
Reducing skin irritation and providing enough moisturizing and soothing care can help recovery.

Jamsil Rejuran is a representative skin booster that helps skin regeneration, and each of its four types has different ingredients and characteristics, allowing selection according to individual skin conditions.
Pain can occur as a characteristic of injection procedures, but it can be reduced in various ways, so please consult with medical staff before proceeding. ^^
