"It’s already getting very hot in mid-June. I want lifting treatment, but I’m worried because of the heat."

"Wouldn’t it feel even more uncomfortable if I get lifting in the summer because of the heat sensation?"

"Is there a lifting treatment that can be done comfortably even in hot weather?"

As mid-June arrives and the full heat of summer begins, many people start to have deeper concerns about skin care. In particular, because lifting procedures use heat energy, they can feel even more burdensome in the summer.

Among those searching for Serf in Hongdae, many people likely worry, “Is it okay to get lifting treatment in the summer?” For those people, today I’ll introduce Serf, a lifting treatment that can be received coolly and comfortably even in the heat.

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

After performing lifting procedures in Hongdae for nine years, I’ve been asked many times every summer, “Can I get lifting treatment even in hot weather?” Since our clinic was the first in Mapo-gu to introduce the Serf device, I think I can answer that question clearly.

Serf is the latest radiofrequency lifting device, released in May 2024. It is a newly introduced device from the merger of Korean medical device company Lutronic and U.S. medical device company Cynosure, and it was designed especially so that it can be received without burden even in the summer heat.

For those looking into Serf in Hongdae, I’ll explain in detail why it can be such a comfortable lifting option even in summer.

The first reason Serf doesn’t feel burdensome even in the heat is its differentiated cooling system.

In general radiofrequency lifting, the heat energy can make it feel hotter and more stuffy in the summer. But with Serf, cooling pulses are delivered one by one each time a shot enters the skin tissue, providing a cooling sensation at the same time.

It’s almost like receiving treatment in a cool, air-conditioned space on a hot summer day; heat energy and cooling happen simultaneously, so the procedure can be comfortable even in the middle of the summer heat. This is why patients describe it as feeling “warm inside the skin, yet cool at the same time.”

In addition, the tip vibrates to help reduce pain, so it does not place much burden on skin that has become sensitive in the summer. Because the pain is low enough that anesthesia is unnecessary, it also removes the extra burden of an anesthesia process in hot weather.

The second reason is that the treatment time is short, so the stress of undergoing treatment in the summer heat is relatively low.

In the case of existing lifting procedures, the anesthesia process alone can take 40 to 50 minutes, making the overall treatment time longer. Spending a long time in a clinic for anesthesia on a hot summer day can itself feel burdensome.

However, Serf does not require an anesthesia process, so treatment is completed in 30 to 40 minutes for 600 shots. Since the procedure is finished in a short amount of time, stress from the summer heat can also be minimized.

The third reason is that individualized treatment is possible, allowing delicate responses even to skin conditions that have become sensitive in the summer.

Serf uses two wavelengths, 6.78 MHz and 2 MHz, and can perform treatment in a total of three modes: Shallow, Middle, and Deep. This allows energy to be selectively delivered according to the condition of everything from skin surfaces made sensitive by summer UV rays or heat to deeper layers.

It also allows energy levels to be adjusted in 10 stages, so treatment can be performed at an appropriate intensity even for skin that has become sensitive in the summer. With four tips (EFFECTOR 05, 10, 40, 60), customized treatment can be applied to various areas of the face, effectively caring for skin that has become fatigued by the heat.

To explain the summer advantages of Serf in Hongdae in a bit more detail,

The EFFECTOR 60 tip of Serf has a surface area 1.5 times larger than Thermage Total Tip. So the satisfaction from 600 shots of Serf is comparable to 840 shots of Thermage, and thanks to the cool cooling system, it can still be received comfortably even in summer.

The fact that results can be seen immediately after the procedure is also a major advantage for those preparing for a summer vacation or an important schedule. The maintenance period is also long, at 9 to 11 months, so if you receive it once in the summer, you can maintain satisfaction until the following summer.

Above all, there is almost no downtime, which means it won’t interfere with outdoor activities or vacation plans in the summer. If you’re searching for Serf in Hongdae and have an important schedule coming up, it would be a good idea to consider it first.

Overall Thoughts on Serf in Hongdae

Why Serf in Hongdae Is a Lifting Treatment That Doesn’t Feel Burdensome, Even in the Heat image 17

I introduced Serf lifting, which can be comfortably received even in the summer heat, but no matter how good the procedure is, an accurate diagnosis and consultation tailored to each person’s skin condition are the most important factors.

Accurately understanding skin conditions changed by summer UV rays or heat, and setting a treatment plan accordingly, is the first step toward satisfying results.

For those looking into Serf in Hongdae, I hope you can receive lifting treatment without burden even in the hot summer, and I recommend getting personalized care through a detailed consultation.

Of course, Serf is a very advanced device and is one of the lifting devices currently available with the fewest drawbacks, but there is no such thing as 100% in skin procedures.

It is important to learn about the characteristics and advantages of the procedure you want to receive, but in dermatology, the most important thing is to carefully check your own skin concerns and current skin condition and then design the procedure in detail.
