Hongdae Rejuran, After the Procedure

"After getting Rejuran treatment, the injection sites turned white and raised. Is this a side effect?"

"After the procedure, small bumps appeared on my face. Is that okay?"

"Other people say nothing is visible after the procedure—am I the only one experiencing something strange?"

If you have received Hongdae Rejuran treatment, you may have worried about this at least once. After the procedure, you may have seen white, raised marks at the injection sites and wondered, "Could this be a side effect?"

But surprisingly, this phenomenon is not a side effect; rather, it is a sign that the procedure was performed successfully. This phenomenon has a special name: it is called the "embossing phenomenon."

Even among those who have searched for Hongdae Rejuran, not many people seem to know exactly about this embossing phenomenon. Today, I’ll explain in detail the embossing phenomenon, an important indicator for determining whether the Rejuran procedure was successful.

Profile

Hello, I’m Director Jo Won-jin of Chai Clinic.

For nine years, I have been performing skin aesthetic procedures in Hongdae, and I have used more than 30,000 bottles of skin boosters such as Rejuran and Juvelook. Among them, Rejuran is one of the skin boosters I recommend most often.

However, when consulting with people who have received Hongdae Rejuran treatment, there are many cases where the embossing phenomenon that appears after the procedure is mistaken for a side effect. Some people even request a follow-up consultation because they think the procedure was not done properly since embossing did not appear after treatment.

In fact, the embossing phenomenon is the most important indicator for determining whether Rejuran has been injected correctly into the proper layer. If you understand this phenomenon properly, you can reduce unnecessary worry after the procedure and also assess to some extent whether the treatment was successful.

What Is the Embossing Phenomenon?

So, what exactly is the embossing phenomenon?

The embossing phenomenon is a natural response that appears when Rejuran is injected precisely into the dermis layer. It refers to the white, raised marks left behind where the needle entered and exited.

"But why does it have to be injected into the dermis for embossing to appear?"

That’s a good question. For Rejuran’s key ingredient, polynucleotide, to work properly, it must be injected into the dermis. This is because the dermis is where fibroblasts, which induce collagen production, are densely distributed.

However, the average thickness of the dermis is only about 1 mm. In particular, the upper dermis is only about 0.3 mm thick. Injecting accurately into such a thin layer requires a great deal of skill from the practitioner.

If the embossing phenomenon is clearly visible after Hongdae Rejuran treatment, it means that Rejuran has been injected accurately into the dermis and that collagen regeneration can proceed properly. On the other hand, if the injection goes deeper than the dermis, the embossing phenomenon is barely visible, and in that case it becomes difficult to achieve the desired improvement in the skin.

Precautions

"I understand that embossing appears, but how long does it last? Isn’t it a problem if it lasts too long?"

This is also something many people worry about. A normal embossing phenomenon usually disappears naturally within 12 to 24 hours. At the latest, it goes away within 2 to 3 days.

While embossing is present, there are generally a few things you should be careful about. If possible, do not touch or press the area with your hands, and avoid washing your face with water that is too hot. It is also recommended to avoid high-temperature environments such as saunas or steam rooms for about a week.

"If embossing does not appear, does that mean the procedure failed?"

This is a common question among people looking into Hongdae Rejuran.

Not having embossing does not necessarily mean failure, but it does suggest that the injection was less likely to have been placed precisely in the dermis. In some cases, embossing may not be very visible.

However, in general, the more clearly embossing appears, the more likely it is that Rejuran has reached the intended target accurately.

Today, we took a detailed look at the embossing phenomenon, which is an indicator of Rejuran treatment success.

The embossing phenomenon is not simply a temporary reaction that appears after the procedure; it is an important sign that Rejuran has been injected into the correct location. If you understand this phenomenon properly, you can reduce post-procedure anxiety and even anticipate the quality of the treatment to some extent.

As many of you may have expected, the most important thing in Rejuran treatment is the practitioner’s skill. Precisely injecting into the thin dermal layer, which is about 1 mm thick, requires considerable experience and technique.

If you are considering Rejuran, it is important to confirm the practitioner’s experience and skill through 충분한 상담 before the procedure. And if embossing appears after treatment, don’t be alarmed—instead, take it as a sign that the procedure was performed successfully.
