Hongdae Rejuran: Don’t Just Leave Sleep Deprivation Unaddressed in the Heatwave

"It’s been so hot lately that I haven’t been sleeping properly, and my skin definitely seems to have gotten worse."

"If I sleep with the air conditioner on, my skin gets dry; if I don’t, it’s too hot to sleep... What should I do?"

"Maybe because I’m sleep-deprived, my skin feels dull and less elastic."

As the heatwave has continued day after day with temperatures exceeding 35°C, the number of people with these concerns has risen sharply. With tropical nights in which the nighttime temperature stays above 25°C continuing, it becomes difficult to get a deep sleep, and as a result, when you look in the mirror in the morning, you can clearly see that your skin condition has declined.

If you searched for Hongdae Rejuran, you are probably looking for a way to fundamentally solve these overlapping summer skin concerns. I will explain why you should not leave the effects of reduced skin regeneration from sleep deprivation, dryness caused by air conditioning, and heatwave stress unchecked.

Profile

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

Over the past 9 years, while performing skin cosmetic procedures in Hongdae, I have met many people who particularly complain about sleep-related skin concerns whenever the heatwave lasts for an extended period. This year, in particular, it seems that consultations like these have increased even more due to the record-breaking heat.

In fact, when sleep quality declines, various changes appear in the skin. Nighttime is when our skin recovers from the stress it received throughout the day and regenerates, and if this process does not happen properly, skin condition naturally declines.

When additional stress from the heatwave is added on top of that, the skin goes through a double burden. If you turn on the air conditioner, it becomes dry; if you don’t, the stress from the heat intensifies, creating a vicious cycle.

In this situation, I’ll explain in detail what help Hongdae Rejuran can provide.

What is Rejuran?

Rejuran is composed of an ingredient called polynucleotide, extracted from salmon DNA. The principle is to inject this ingredient into the dermis layer of the skin to induce skin regeneration.

The reason Rejuran draws particular attention in situations of sleep deprivation caused by heatwaves is its excellent water affinity. Even when the skin has become dry deep inside from constant exposure to air conditioner airflow, the polynucleotide ingredient attracts moisture and helps make the skin feel comfortable and hydrated from within.

Many people say their skin condition has declined but they do not want Botox or fillers. In such cases, Rejuran is the kind of treatment needed.

Among Hongdae Rejuran treatments, I especially recommend Rejuran HB plus for people who are sensitive to pain. It is a product that adds hyaluronic acid, a moisturizing ingredient, and lidocaine, an anesthetic ingredient, to the existing Rejuran Healer, allowing strong hydration while placing less burden on skin that has become sensitive due to sleep deprivation.

Rejuran shows its true value only when it is injected precisely into the thin layer of the dermis, around 1 mm deep. Because fibroblasts, which induce collagen production, are densely distributed in the dermis, Rejuran must be placed there for collagen synthesis to be induced and for skin regeneration to occur.

Why Rejuran?

So, specifically, how can Rejuran help skin that is tired from sleep deprivation in a heatwave?

First, it can provide fundamental hydration from within the skin.

When the skin barrier function weakens due to sleep deprivation, moisture loss accelerates. If you add air conditioner airflow to that, the skin falls into a chronic state of dehydration. In this situation, Rejuran’s polynucleotide ingredient attracts moisture from deep within the skin and offers a fundamental solution.

Second, it improves the skin’s regenerative ability.

Rejuran can help with the skin regeneration process that did not properly occur during the night. The polynucleotide ingredient injected into the dermis induces collagen production and enhances the skin’s ability to recover on its own.

Third, various products allow personalized care.

Even in situations of sleep deprivation caused by heatwaves, skin responses can differ from person to person. For those who have become sensitive to pain, Rejuran HB plus can be selected, and for those especially concerned about fine lines around the eyes, Rejuran i can be chosen, allowing customized care.

The most important thing in Hongdae Rejuran treatment is injecting it at the correct depth. Whether the procedure was done properly can be checked through the embossing effect: if the injection site appears white and raised, it is a sign that it was injected accurately into the dermis.

Hongdae Rejuran overall conclusion

Of course, even in a heatwave, the most important thing is to make every effort to improve your sleep environment as much as possible. When using air conditioning, it is also important to adjust the airflow so that it does not blow directly onto your face and to maintain proper indoor humidity. Drinking enough water, about 1.5 to 2 liters a day, is also essential.

Above all, personalized consultation that matches your individual skin condition is important. Even if the concern is the same sleep deprivation issue, each person has different skin type and living environment, so finding a solution that suits the individual is the most important thing.

Rejuran is generally recommended to be received 3 to 5 times at intervals of 3 to 4 weeks. In particular, during the summer, when the skin is under more stress, consistent care may be even more important.

Do not leave skin that is exhausted from sleep deprivation in the heatwave unattended. I hope you regain healthy skin through a fundamental solution.

I hope this information is helpful for those looking into Hongdae Rejuran.
