Jamsil Station Dermatology Rejuran Healer Skin Booster: From Ingredients to Effects and Benefits

Solution for Regenerating Summer-Damaged Skin: Rejuran Skin Booster

Hello! This is Jamsilon Dermatology :)

During the summer, when strong ultraviolet rays and air-conditioning repeatedly dry out the skin, it can easily become tired and damaged. In particular, frequent outdoor activities and increased sweat and sebum production often weaken the skin barrier! That is why, during this season, simple moisturizing alone is not enough, and regenerative care that helps the skin recover on its own is needed. The “Rejuran Skin Booster” introduced today can be an especially effective solution for skin damaged by summer—so let’s take a look at its features and effects together.

Why Skin Gets Damaged in Summer

Summer is a harsh season for the skin in many ways. Continuous exposure to ultraviolet rays breaks down collagen in the skin, and moisture from the epidermis evaporates easily, reducing elasticity and radiance. In addition, high temperature and humidity increase sebum production and enlarge pores, while air-conditioning dries out the skin. These combined external stimuli weaken the skin barrier and even reduce the skin’s ability to regenerate.

Because skin is so easily damaged in summer, intensive care is needed to repair the skin barrier and support regeneration. In particular, for skin that has become sensitive to sunlight, procedures with minimal irritation and improved recovery are suitable! Rejuran is a representative regenerative skin booster that meets these conditions and is an option that can effectively improve summer skin concerns.

• Ultraviolet rays / air-conditioning / sweat

• External pollution / friction

• Moisture evaporation / sensitivity

What Is Rejuran Healer?

Rejuran Healer is an injectable treatment that induces skin regeneration, and its key ingredient is a special component called PN (polynucleotide). PN is a DNA fragment extracted from salmon and has a structure similar to human skin, so when injected into the body, it causes little irritation and responds naturally. This ingredient increases the activity of fibroblasts needed to restore damaged skin tissue and promotes the production of collagen and elastin, thereby inducing overall skin regeneration.

Unlike injections that simply fill the skin, Rejuran takes a “healing-centered” approach that restores the environment within the skin. By inducing mild inflammation and helping the skin regenerate on its own, it allows you to experience changes over time, such as finer skin texture and improved firmness! Many people choose it especially because it can also be used on sensitive or damaged skin :)

Rejuran Healer Effects & Benefits

Changes in skin texture or tone are often the first things many people notice after Rejuran treatment. The regenerative action of the PN ingredient in Rejuran plays a major role in refining pores and making the skin feel smoother. Some people may temporarily feel soothed or see a brighter appearance, but in reality, this is part of the process of gradually restoring the skin’s underlying strength.

A major advantage of Rejuran is that it can be applied relatively comfortably even to skin that has become sensitive due to summer ultraviolet rays or mask irritation. The key is not simply a visible change on the surface, but the creation of an environment in which the skin barrier can recover on its own. Rather than expecting every improvement from a single treatment, the changes tend to become more evident with repeated sessions at regular intervals.

How to Care After Rejuran Treatment

After the procedure, temporary reactions may appear depending on the skin condition. Mild redness or stinging is due to the injection marks and tissue reaction, and in most cases it passes lightly without any special issue. As the PN ingredient works deep within the skin and induces a natural regeneration process, it can be seen as a sign of that process. It usually settles within a day or two, and during this period it is best to avoid strong ultraviolet rays and high-temperature environments.

When the skin is in a sensitive state, aftercare should also be adjusted a little. Washing your face gently with lukewarm water and using a sufficient amount of a low-irritation moisturizer to replenish hydration can be helpful. Sun protection is especially essential~ Not only before going out, but even when indoors, it is good to apply sunscreen as a habit, as this can positively affect skin recovery. Please note that the duration of the treatment effect may vary depending on how carefully you manage aftercare :)

LDM MED Tri, a Good Option to Use Together

If you want to continue the treatment effect more gently, using a soothing device together can also be a good option. Among them, “LDM MED Tri” is a device that uses multiple frequencies of ultrasound simultaneously to help restore balance within the skin. Rather than acting only on the surface, it delivers vibrations to deeper layers to minimize heat and irritation while inducing skin regeneration.

In particular, right after an injection procedure, the skin can easily become sensitive, and this device is useful for calming that condition quickly. While the PN ingredient works within the skin, LDM MED Tri helps block external irritation and maintain moisture balance. During the summer, when the skin reacts sensitively, combining these two types of care may be much more advantageous in terms of recovery speed and skin texture improvement.
