What is the biggest concern for people looking into Hongdae Rejuran? Yes, pain, of course. Rejuran is a treatment consistently favored by those seeking natural-looking beauty, but it is also well known for being quite painful.

"I heard that your skin looks much better after getting a skin booster, but isn’t it extremely painful?"

"Is there a skin booster that provides good satisfaction without being painful?"

These are questions I have heard consistently over my nine years of performing skin booster treatments. No matter how beneficial a treatment may be for the skin, it is understandable that people may hesitate if the pain is too severe.

Because I also try new products on my own skin first whenever they are released, I fully understand your concerns.

Even so, those searching for Hongdae Rejuran are likely hoping to find a product that improves the skin while causing less pain.

I have prepared this information for those people. The product I will introduce today is Rejuran HB plus, one of the best-known products in the skin booster field.

Hello. I am Dr. Won-jin Jo, director of Chai Clinic.

First, I will briefly explain Rejuran.

Rejuran is composed of a substance called polynucleotide (PN). It is extracted from salmon reproductive cells and is considered a biocompatible substance. As a result, it generally causes relatively little foreign-body reaction.

The principle is to inject this ingredient into the dermal layer to induce skin regeneration and improve elasticity.

Many people receive it when they are concerned about dry skin or fine lines. As those looking into Hongdae Rejuran may already know, the level of satisfaction is generally quite high.

However, the reason many people hesitate is the intense pain, which can leave them feeling drained. Many people struggle to choose between the high level of satisfaction from the skin improvement and the significant pain.

But why is Rejuran, which is said to be beneficial for the skin, so painful?

As mentioned earlier, the main target of Rejuran treatment is the dermal layer of the skin. However, the dermal layer is extremely thin, measuring approximately 1 mm in thickness.

In injection procedures, targeting deeper areas of the skin generally reduces pain, while targeting areas closer to the skin’s surface tends to cause more pain.

The dermal layer is not only a painful layer to inject into because of the injection depth itself, but it also has a relatively high density of ingredient molecules, making injection painful.

Rejuran HB plus, the product I am discussing today, was developed to help reduce this pain associated with Rejuran.

Rejuran HB plus is made by combining the existing Rejuran Healer product with the anesthetic lidocaine and the moisturizing ingredient hyaluronic acid.

It is known for significantly reducing pain while preserving as much of the satisfaction associated with Rejuran Healer as possible.

If the pain level of Rejuran Healer is considered to be around 5, the pain level of Rejuran HB plus may be considered to have been reduced to around 2.

Those who are particularly sensitive to pain or are hesitating to receive Rejuran because of the pain may want to consider Rejuran HB plus.

I will briefly explain the benefits of Rejuran products.

First, their high affinity for water can make the skin feel comfortable and hydrated from within.

You may have heard comments like these:

"My skin does not look particularly dry on the surface, but it feels tight from within."

"I apply plenty of moisturizing products, but my skin still feels dry."

Yes, when tightness comes from within the skin, there are areas that topical moisturizing products cannot fully address. Rejuran products may be suitable for people in this situation.

The polynucleotide ingredient in Rejuran has a very strong affinity for water. Because it draws in moisture, the skin can feel more comfortable and hydrated from within.

Second, it can improve the skin’s regenerative capacity.

By improving the skin’s regenerative capacity, it may help improve the overall texture and tone of the skin.

For those concerned about their skin tone or overall skin texture, Rejuran may be helpful.

Many people looking into Hongdae Rejuran may be considering a skin booster treatment for the first time. If you are concerned about the pain of Rejuran, we recommend starting with Rejuran HB plus.

Those looking for a dermatology clinic for Rejuran treatment should also keep in mind that the provider’s experience and skill are very important.

For this Rejuran treatment, it is important to inject accurately into the dermal layer. Since the dermal layer is extremely thin, it is advisable to check the provider’s level of experience before choosing a dermatology clinic.

Today, I have discussed the skin booster Rejuran. You may think of Rejuran simply as a “vitamin” in the field of cosmetic dermatology.

Although there is a recommended number of sessions in the treatment guidelines, those who do not find the time or cost burdensome may receive the treatment at their convenience.

If you are looking into Hongdae Rejuran, be sure to check the provider’s experience and skill first when choosing a dermatology clinic.

This has been Chai Clinic, customizing your beauty. Thank you.
