"These days, when I turn on the air conditioner, my skin gets so dry."

"When I go outside, my skin stings because of UV rays, and when I come back inside, it feels tight because of the air conditioner... What should I do?"

At the end of June, as summer begins in earnest, more and more people are having these concerns. Indoors, the air conditioner causes dryness; outdoors, strong UV rays and high humidity increase sebum production... it is a season when the skin is under stress all day long.

People who have searched for Hongdae skin boosters are probably looking for a way to solve these summer skin concerns. Now is the time to find a fundamental solution for skin that is becoming exhausted between the air conditioner and UV rays.

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

For the past nine years, while performing dermatologic aesthetic procedures in Hongdae, I have seen every year that around this time, the number of people complaining about difficulties with skin care increases sharply.

As the temperature difference between indoors and outdoors grows to more than 10 degrees Celsius, and the time spent exposed to strong UV rays gets longer, the skin struggles to adapt throughout the day. As a result, skin barrier function weakens, moisture loss accelerates, and at the same time, sebum production increases, creating a complex set of problems.

What fundamentally helps solve these summer skin concerns is the skin booster. Skin boosters, often called the "vitamin" of aesthetic dermatology, enhance the skin’s own regenerative ability and help it adapt better to changes in the external environment.

There are many types of skin boosters, but today I will explain the two most well-known and widely chosen products: Rejuran and Juvelook.

First, I will explain why Rejuran is good for summer skin care.

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

The reason Rejuran is especially good in summer is its affinity for moisture. Even when the skin has become dry deep inside due to continuous exposure to air conditioning, the polynucleotide ingredient in Rejuran attracts moisture and makes the skin comfortable and hydrated from within.

Many people say in summer, "It seems oily on the outside, but inside it feels tight." In cases like this, Rejuran is exactly what is needed.

Among those looking into Hongdae skin boosters, if you have these kinds of complex skin concerns, Rejuran is worth considering.

Rejuran comes in several types, so it can be chosen according to each person’s situation. In summer, I especially recommend Rejuran HB Plus. It is a product that adds hyaluronic acid, a moisturizing ingredient, and lidocaine, an anesthetic ingredient, to the existing Rejuran Healer. It helps replenish moisture while placing less burden on skin that has become sensitive in the summer.

Rejuran is usually recommended 3 to 5 times at intervals of 3 to 4 weeks.

Next, I will explain how Juvelook helps with summer skin care.

Juvelook is a skin booster in which powder containing a PDLLA ingredient is diluted with injection water and injected into the sub-dermal layer. As it is called a "collagen stimulator," it works by stimulating collagen production to make the skin layer itself thicker and firmer.

There are three main reasons Juvelook is good in summer.

First, it is excellent for improving fine wrinkles caused by UV exposure.

When exposed to strong UV rays, skin elasticity declines and fine wrinkles become more noticeable. Juvelook stimulates collagen production and thickens the skin layer, naturally improving these fine wrinkles.

Second, it helps care for enlarged pores caused by high humidity.

In summer, high humidity and increased sebum production often make pores look larger. Juvelook helps reduce pore size by making the skin tissue firmer.

Third, it adds elasticity to skin that has become lax due to air conditioning.

Continuous exposure to air conditioning dries out the skin and causes it to lose elasticity, but Juvelook enhances the skin’s own regenerative ability and helps restore natural elasticity.

Among Hongdae skin boosters, Juvelook is especially popular with those who want to improve their skin condition before a summer vacation. If you receive it about 3 times at 4- to 5-week intervals, you can build better skin condition in time for your trip.

Today, I talked about skin boosters that can help with summer skin care.

Of course, no matter how good the procedure is, there are limits if basic daily habits do not support it. In summer, it is important to use sunscreen more carefully than usual, drink enough water, and reduce the time spent directly exposed to air conditioning.

Above all, personalized consultation that matches your skin condition is most important. Even with the same summer skin concerns, each person has a different skin type and lifestyle, so just as Chai Clinic’s philosophy says that no two skins are the same, finding the solution that suits each individual is the most important thing.

I hope this information is helpful for those looking into Hongdae skin boosters. If you want to bring vitality back to skin tired from the summer air conditioner and UV rays, looking into a skin booster that matches your skin condition can be a good option.

This has been Chai Clinic, customizing your beauty. Thank you.
