Why You Should Not Ignore Dry Skin in the Middle of Summer: Hongdae Rejuran

“When I woke up this morning, my skin felt so tight.”

“Maybe it’s the air conditioner, but my skin feels dry from the inside. It’s sticky on the outside, so why does it feel so tight inside?”

“It’s the rainy season, but I’m worried my skin actually feels drier.”

In July, during the rainy season, the intense heat has continued day after day, and indoor humidity is soaring above 70%. In this kind of weather, many people are running both dehumidifiers and air conditioners at the same time to create a comfortable indoor environment.

The problem is that, in the process of controlling humidity like this, the skin is being exposed to unexpected stress. Dehumidifiers remove moisture, and air conditioners lower the temperature with cold air. Skin that has to endure this all day long is highly likely to see its condition decline.

If you searched for Hongdae Rejuran, you are probably looking for a way to fundamentally solve these complicated summer skin concerns. Skin that feels sticky on the outside but tight on the inside is one of the unavoidable skin issues of the summer season.

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

Over the past nine years, while performing aesthetic skin procedures in Hongdae, I have met many people who have raised similar concerns, especially every summer and during the rainy season. This year, in particular, it seems that even more people are coming in for consultations about skin problems caused by dehumidifiers and air conditioners.

If you look at indoor conditions during the rainy season, it makes sense that these skin concerns arise. When outdoor humidity during the rainy season reaches 85–95%, dehumidifiers indoors are working hard to maintain the proper humidity level of 40–60%. At the same time, air conditioners are continuously blowing cold air to keep the temperature at 25–27°C.

During this process, the skin undergoes rapid environmental changes several times a day. It starts the morning in a space where the dehumidifier is running, then moves to a cold 25°C space with the air conditioner on, and then is repeatedly exposed to a dry environment where the dehumidifier’s air blows directly on it.

Under these extreme environmental changes, the skin barrier gradually weakens, and moisture loss accelerates. The result is the complex skin condition of feeling “sticky on the outside but tight on the inside.”

So how can Rejuran help with these rainy-season skin concerns?

Rejuran is made of a component called polynucleotide, extracted from salmon DNA. The principle is to inject this ingredient into the dermis to induce skin regeneration.

The important point here is Rejuran’s excellent affinity for moisture. Even when the skin has become dry deep inside due to continuous exposure to dehumidifiers and air conditioner airflow, Rejuran’s polynucleotide ingredient attracts moisture and helps the skin feel comfortable and hydrated from within.

Many people say, “It feels oily on the outside, but tight from the inside,” and this is especially common during the rainy season. In cases like this, Hongdae Rejuran is needed.

For people who are sensitive to pain, I often recommend Rejuran HB Plus. It is a product that adds hyaluronic acid, a moisturizing ingredient, and lidocaine, an anesthetic, to the existing Rejuran Healer, helping to relieve the burden on the skin while also greatly aiding fundamental moisture replenishment.

Above all, Rejuran shows its true value only when it is accurately injected into the thin layer of the dermis, about 1 mm deep. Because fibroblasts that induce collagen production are concentrated in the dermis, Rejuran must be delivered there for collagen synthesis to be triggered and skin regeneration to be induced.

Whether the procedure was performed properly can be checked through the embossing effect. This is the phenomenon where the injection sites appear white and raised. It is a sign that the product was injected accurately into the dermis. This embossing effect usually disappears naturally within 12–24 hours, so there is no need to worry too much.

Here are the points to keep in mind when getting Hongdae Rejuran treatment during the rainy season.

First, adjust the number of treatments and the interval.

Some people’s skin becomes more sensitive than usual during the rainy season. For these individuals, it is recommended to follow the Rejuran treatment interval recommended at 3–4 week intervals according to their own skin condition. Rather than trying to see quick changes, the goal is to help the skin adapt gradually.

Second, choose the type of Rejuran.

If you are sensitive to pain or your skin is already irritated by rainy-season breakouts, Rejuran HB Plus is a good choice. Because it contains lidocaine, it can reduce pain by about 80%, and the hyaluronic acid also provides a satisfying moisturizing effect.

If dryness is especially severe in thin areas such as around the eyes or mouth, combining it with Rejuran I is also a good option. It has low viscosity and spreads well, so it can be applied to delicate areas without burden.

Today, I talked about Rejuran for skin that is struggling between dehumidifiers and air conditioners during the rainy season.

Of course, no matter how good the procedure is, there are limits if basic lifestyle habits do not support it. When using a dehumidifier, it is important to keep the door closed and avoid staying in that space for too long, adjust the airflow so that the air conditioner does not blow directly onto your face, and drink enough water—about 1.5 to 2 liters a day.

Especially during the rainy season, indoor humidity changes rapidly, so the skin experiences a lot of stress as well. At times like this, procedures such as Rejuran that fundamentally improve the skin from within can be very helpful.

Most importantly, personalized consultation tailored to each person’s skin condition is essential. Even if the skin concerns are the same rainy-season dryness, each person has different skin types and living environments, so just as Chai Clinic believes that no two skins are the same, finding a solution that fits the individual is most important.

I hope this information is helpful for those looking into Hongdae Rejuran. If you want to find a fundamental solution for skin that is worn out between dehumidifiers and air conditioners, looking into Rejuran treatment that suits your skin condition could be a good option.
