Take Action Early for Seasonal Skin Changes, or You’ll Regret It

"Lately, the large temperature swings have made my skin sensitive."
"My skin, which has been stressed by UV exposure all summer, suddenly feels dry."
"My skin condition drops sharply every time the seasons change. How should I prepare?"
As fall and the seasonal transition approach, more and more people are having these concerns. This is the time when skin that has been worn down by strong summer UV rays and air conditioning faces sudden temperature changes and dry air, leading to a sharp decline in condition.

If you have searched for Hongdae skin boosters, you are probably looking for a way to fundamentally solve these seasonal skin concerns. When simple moisturizing care has its limits, it is time to consider a procedure that helps improve the skin’s own regenerative ability.
Why Should You Start Before the Seasonal Change?

Hello, I’m Director Jo Wonjin of Chai Clinic. Based on my experience performing more than 30,000 skin booster procedures over the past 9 years, I can say that seasonal preparation should be done as prevention, not after problems occur.

Skin boosters are procedures often called the vitamins of aesthetic dermatology. Rather than creating an immediate change like Botox or fillers, they work by gradually enhancing the skin’s own regenerative capacity. That is why it is important to begin now, before the season fully changes, so you can build a stronger skin foundation that can withstand sudden climate shifts.

Among Hongdae skin boosters, Rejuran and Juvelook are especially representative procedures that deliver excellent satisfaction for seasonal preparation.
Building a Moisture Defense Barrier for the Season with Rejuran

Rejuran is a skin booster that induces skin regeneration by injecting polynucleotide ingredients extracted from salmon DNA into the dermis. The reason Rejuran is especially good for seasonal preparation is its excellent affinity for moisture.

During seasonal transitions, many people say, "It looks fine on the outside, but my skin feels tight underneath." With rapid humidity changes, moisture escapes from deep within the skin, and ordinary moisturizing products have limitations in such situations.
Rejuran’s polynucleotide ingredients have excellent water-attracting ability, helping the skin feel comfortable and hydrated from within.
It also stimulates fibroblasts, which induce collagen production in the dermis, making it possible to support both skin regeneration and improved elasticity at the same time.

For seasonal preparation, I especially recommend Rejuran HB Plus. This product adds hyaluronic acid, a moisturizing ingredient, and lidocaine, an anesthetic ingredient, to the existing Rejuran Healer, allowing for strong hydration with less burden on skin that has become sensitive during the season change.

Strengthening the Skin’s Elasticity Foundation for the Season with Juvelook

Juvelook is a skin booster in which PDLLA powder is diluted with injection solution and injected into the subdermal layer. As a so-called collagen stimulator, it works by stimulating collagen production to make the skin layers thicker and firmer.

The reason Juvelook matters during seasonal transitions is its ability to improve fundamental resistance by strengthening the skin layers. It helps improve fine lines made more visible by summer UV exposure, enlarged pores caused by air-conditioning, and overall skin laxity, creating skin that remains stable even through abrupt climate changes.

Juvelook’s PDLLA particles are smaller and finer than those of Sculptra, making them well suited for skin-layer application. With a lower melting point as well, it is a skin booster chosen by many people. In particular, when combined with radiofrequency lifting treatments such as Thermage or Serf, it can create remarkable synergy.
This is because the 55°C melting point of PDLLA and the 42–60°C temperature range generated by radiofrequency devices work together to promote smoother collagen production.
What You Should Know Before Preparing for Fall with Skin Boosters

When preparing for the fall season with Hongdae skin boosters, the most important factor is the practitioner’s skill. Rejuran must be injected precisely into the thin dermis of about 1 mm, and Juvelook must be injected accurately into the subdermal layer to increase satisfaction and minimize side effects.

Skin boosters are generally recommended at intervals of 3 to 4 weeks for about 3 to 5 sessions. If you start now, you can build a solid skin foundation that will prepare you not only for the fall season but also for early winter.
The most important thing is a detailed consultation tailored to each person’s skin condition.
Even with the same seasonal concerns, each person has different skin types and lifestyle patterns, so finding a customized solution that fits the individual is the most important thing.
September is still hot, but for the coming fall season, I hope you can start now with Hongdae skin boosters to strengthen your skin foundation and enjoy the season more beautifully.
This has been Chai Clinic, customizing your beauty. Thank you.
