Sinnonhyeon Dermatology Clinic: Why Rejuran Causes Embossing and Its Effects

[Lee Yudeuk, Dermatology Specialist]

Hello,

A place that creates a comfortable face rather than excessive change.

This is Leejham Dermatology Clinic.



Today, I’d like to write for those who are highly interested in Rejuran at our Sinnonhyeon dermatology clinic, especially those who have already received it but became worried after noticing small bumps on the skin surface. If you looked in the mirror and suddenly found a bumpy texture, I can fully understand how startled and anxious you must have felt.



In the clinic, after meeting many patients over a long period of time, it is not uncommon for people to worry on their own because they lack information not only about the procedure itself but also about the reactions that may appear afterward. In particular, those experiencing a skin booster for the first time may find it difficult to tell whether such a reaction is a normal part of the process.



Through today’s post, let’s calmly look at what the embossing phenomenon is, why it happens, and how it is best managed. I think reading to the end will help ease some of that anxiety.

The ingredients of Rejuran and how they work within the skin

Rejuran is a skin booster

whose main ingredient is PDRN.



PDRN is a DNA fragment extracted

from salmon germ cells,

and it is a component involved in repairing damaged cells within the skin

and promoting collagen synthesis.



To put it simply, it works like reinforcing the foundation of a building that is gradually deteriorating due to aging,

sending recovery signals deep within the skin tissue and helping the skin itself

create new elastic fibers.



Sinnonhyeon dermatology clinic’s Rejuran is relatively gentle in stimulation

and can quietly bring about changes from within the skin,

so it can be a helpful option for people whose skin aging has progressed over a long time or for those with uneven skin texture.



At Leejham Dermatology Clinic, after carefully examining each person’s skin condition and concerns,

we individually establish skin booster plans that include Rejuran.



The principle behind embossing



The phenomenon where small bumpy protrusions appear on the skin surface after Rejuran treatment

is called the “embossing” phenomenon.



During consultations for Rejuran at our Sinnonhyeon dermatology clinic,

we also explain this in advance in sufficient detail.

Embossing is when the PDRN injected into the shallow dermal layer has not yet settled within the skin,

after which the injection site may be subtly visible on the skin surface.



Because Rejuran is injected at very small intervals into the upper dermis,

this phenomenon occurs on a similar principle to how cotton clumps inside a quilt can show unevenness on the outside.



It may appear more noticeable in people with thin skin or little subcutaneous tissue,

or depending on the injection amount and depth.



In addition, after the procedure, temporary changes in blood flow may make the area around the injection site appear more prominent.



What is important is that in most cases,

this phenomenon gradually diminishes over several days after the procedure as the ingredients are absorbed into the skin.



The positive changes Rejuran can bring to the skin

 

The core action of Rejuran is to restore skin elasticity

and promote collagen synthesis.



When the PDRN ingredient activates

growth factor receptors in skin cells,

fibroblasts in the dermis are stimulated and begin synthesizing collagen and elastin anew.



Through this, the skin tissue

gradually becomes firmer,

and you may experience positive changes such as a more refined skin texture.



Thanks to the anti-inflammatory action of Rejuran at our Sinnonhyeon dermatology clinic,

many people also feel that chronic irritation in the skin is eased,

leading to changes in their overall skin condition.



You may also often hear that the skin feels more moisturized

or looks less dull.



However, the degree of change can vary depending on an individual’s skin condition, age, and lifestyle,

and more stable progress can be expected when it is received consistently at regular intervals.



It is best to approach it with the mindset of accompanying the process of the skin slowly recovering on its own.



The right way to care for skin when embossing appears



When embossing appears,

the first thing you should do is

“wait long enough.”



In most cases, the embossing will gradually fade

between 3 days and 1 week after the procedure.



During this period, it is best not to touch or rub the area excessively,

and when washing your face, do so gently and lightly.



Hot saunas or jjimjilbangs can

place heat stress on the skin,

so it is better to avoid them immediately afterward.



Drinking enough water and using a mild moisturizing product

to protect the skin barrier are also helpful.



It is recommended that you postpone exfoliating products or deep cleansing

until the skin has recovered.



You should also be sure to apply sunscreen even after the procedure,

because if temporarily sensitive skin is exposed to ultraviolet rays,

pigmentation may occur.



If embossing lasts for more than 1 to 2 weeks

or is accompanied by redness or pain,

it is advisable to visit the medical institution where you received the procedure for an evaluation.



For those who were worried about the embossing reaction



When treating patients who visit the clinic,

I often come across cases where they were worried on their own

without realizing that the embossing reaction can appear after Rejuran.



Small protrusions on the skin surface can feel startling when you first see them.



However, embossing is a temporary reaction that appears while the PDRN ingredient is settling into the skin,

and in most cases it is naturally absorbed within a few days.



If you know enough in advance about the reactions that can occur after the procedure,

you can observe the progress with much more peace of mind.



It is important to understand that this is part of the skin’s own recovery process,

and to calmly observe even small changes.



Rather than worrying alone,

please also remember that you have the right to receive a sufficient explanation from the medical staff.



A place that stays with you for a long time through honest care



In skin care, I believe the most important thing is

not only the method itself but also

“a sufficient understanding of that method.”



Even reactions that may seem startling at first,

such as embossing,

can be observed much more comfortably

if you know about them in advance.



For any skin care method,

including Rejuran at our Sinnonhyeon dermatology clinic,

please be sure to check the principles, expected course, and precautions before receiving it.



Leejham Dermatology Clinic

always centers its practice on the belief that it is a place that creates a comfortable face rather than excessive change.



Rather than a single flashy result,

we aim to build long-term trust through diagnosis and solutions tailored to each person’s skin.



With proven methods and honest care,

we will continue to stay by your skin.
