I would like to give my parents a lifting treatment in May. Which one would be best?
I’m looking for a lifting treatment with no downtime because we have a family gathering.
My parents are sensitive to pain. Is there a less painful lifting treatment?
With May being Family Month, many people are considering lifting treatments either with their parents or as a gift for them.
When searching for Hongdae Thermage, “Serep” and “Thermage” are frequently mentioned among the many available treatments.
Today, we will examine the differences and features of the two treatments and compare which one may be more suitable for each family member during Family Month.
Professional Background

Hello, I am Jo Won-jin, director of Chai Clinic.
Over the past nine years of performing lifting treatments in Hongdae, I have noticed that particularly in May, more people visit together as families.
Many people are looking for a meaningful gift for Family Month or want to care for their skin ahead of a family event.
Among lifting treatments, Thermage, which has more than 10 years of proven history, and Serep, a newcomer launched in May 2024, each have their own features.
Based on my experience being the first to introduce Serep equipment in Mapo-gu, I will explain the differences between the two treatments in detail.
Hongdae Thermage: Thermage vs. Serep
First, let’s look at the basic principles and features of the two treatments.
Thermage is a lifting treatment that uses radiofrequency energy. It delivers energy through the skin tissue to below the dermal layer, but it does not reach the fascial layer.

Heat stimulation causes collagen denaturation. During this process, collagen regenerates, resulting in smoother skin texture. Within one to three months after treatment, the skin texture becomes more refined, the complexion appears brighter, pores become less noticeable, and the facial contours gradually become more defined.
By contrast, Serep is the latest radiofrequency lifting device, launched in May 2024. It uses two wavelengths and offers three treatment modes: Shallow, Middle, and Deep.

Its distinguishing feature is that it addresses the issue of delivering energy to deeper layers, which was a limitation of conventional radiofrequency lifting treatments.
It also has four tips—EFFECTOR 05, 10, 40, and 60—allowing customized treatment for various areas of the face.

The biggest difference between the two treatments is pain.
Serep has a differentiated cooling system, so a cooling pulse operates each time a shot is delivered into the skin tissue. As a result, pain is significantly reduced, to the point that treatment can be performed without anesthesia.
Hongdae Thermage: Which Lifting Treatment Should You Choose?
Then, which treatment may be suitable for different family members during Family Month?

First, Serep may be more suitable for parents who are sensitive to pain.
Serep causes so little pain that it can be performed without an anesthesia process. Thermage FLX also causes less pain than before thanks to its improved cooling system, but anesthesia is still generally required. Parents who are particularly sensitive to pain may appreciate the comfort provided by Serep’s cooling system.
Second, Serep may be advantageous if you want treatment in a short amount of time during a busy schedule.
Because Serep does not require anesthesia, treatment takes about 30–40 minutes for 600 shots. Thermage, on the other hand, requires 40–50 minutes just for anesthesia, making the total treatment time longer.
For those with many family gatherings scheduled during Family Month, Serep—sometimes called a “lunchtime lifting treatment”—offers greater convenience in terms of time.

Third, Thermage may be suitable if proven data matters most.
Thermage is a treatment with more than 10 years of accumulated data, and its satisfaction has been consistently demonstrated. Those who prefer a treatment that has been evaluated over a long period rather than a newer treatment may choose Thermage, a long-established lifting device.
Finally, regarding energy delivery, the Serep EFFECTOR 60 tip has an area 1.5 times larger than the Thermage Total Tip. This means that 600 Serep shots may offer a level of satisfaction similar to 840 Thermage shots.

If you are looking into Hongdae Thermage, Serep may also be worth considering.


For those looking into Hongdae Thermage, especially those who want to receive treatment with their parents during Family Month in May, it is important to choose according to each person’s skin condition and priorities.
Serep may be suitable for busy people today or parents who are sensitive to pain because it causes less pain and requires less treatment time. Thermage, on the other hand, may be suitable for those who value trust based on data proven over a long period.
Above all, the most important thing is a customized treatment plan based on a detailed consultation and skin analysis.
During Family Month in May, beginning a skin-care routine with your loved ones may also be a meaningful experience.
I hope this information is helpful to those looking into Hongdae Thermage.
