"My skin condition has worsened, and I’d like to get a lifting treatment. Will it take a long time?"

"I want to get a lifting treatment, but I don’t have the time. Is there any option for me?"

Among those looking into Hongdae Shrink, it seems that many would like to receive a lifting treatment but find it difficult to set aside extra time for it.

They also have daily work or studies to attend to, so they need a treatment without downtime such as bruising or swelling.

Today, I would like to introduce two treatments that may be suitable for those who want a lifting treatment but have difficulty finding the time for it.

They are known as “lunchtime lifting” treatments.

Hello. I am Director Jo Won-jin of 차이의원.

As the dry weather continues day after day, many people are likely concerned about their deteriorating skin condition. After performing aesthetic dermatology treatments in Hongdae for nine years, I have noticed that especially many people worry about their skin during this season.

However, not having time to receive care can often make the stress even worse.

The two lifting treatments I would like to discuss today for such people are

“Shrink” and “Therf.”

First, let’s look at Shrink.

Shrink is a lifting device that uses high-intensity focused ultrasound.

What are the advantages of Shrink?

First, it allows for individualized treatment design.

Shrink consists of various cartridges, with a total of seven cartridges. By delivering energy to different layers, the treatment can be designed according to each person’s skin condition or treatment area.

To explain briefly, Derma Shrink promotes collagen regeneration in the upper dermal layer and improves fine lines.

Eye Shrink can be applied to areas with thin skin, such as around the eyes and neck wrinkles.

Cell-Up Shrink delivers energy to the subcutaneous layer at a depth of 3.0 mm, helping improve the skin’s firmness.

Line-Up Shrink forms thermal coagulation zones in the fascial layer at a depth of 4.5 mm, lifting sagging facial contours.

In addition, the Derma Booster, Cell-Up Booster, and Line-Up Booster tips can deliver ultrasound energy at depths of 1.5 mm, 3.0 mm, and 4.5 mm, respectively. They can be applied according to each person’s skin condition and concerns.

Second, there is almost no downtime.

As mentioned earlier, people who want to receive skin care but do not have the time are likely those who have to go to work every day or focus on their studies. For this reason, treatments involving bruising or swelling may feel somewhat burdensome.

However, Shrink causes very little of this kind of discomfort. Since it is possible to return to daily activities immediately after the treatment, you may have fewer concerns about downtime.

Third, the treatment is quick.

Yes, this may be the most important reason for people looking into Hongdae Shrink. Shrink causes very little pain. The lack of pain means that a separate numbing period is not required.

Lifting devices generally require time for numbing, and this process tends to take quite a while. Although it varies by device, lifting treatments that require numbing usually take 40–50 minutes or more just for the numbing process.

Since Shrink omits this process, the treatment is completed quickly. It usually takes less than 20 minutes for 1,000 shots, so even those with limited time should be able to receive it.

Shrink may be worth considering for those who are beginning to develop fine lines or who have thin skin but want to improve its firmness.

The next lifting treatment we will look at is Therf. It may be unfamiliar to those who have only just started looking into Hongdae Shrink.

However, as a newer device, it offers many advantages.

The advantages of Therf include:

First, it allows for precise treatment design.

Therf uses two frequencies. By combining the two frequencies, it can selectively deliver thermal energy from the shallow to the deep layers of the skin.

To explain briefly, it offers three depth settings and ten energy-level settings, allowing the treatment to be tailored to the skin type and treatment area.

Second, it causes very little pain.

As a recently introduced device, Therf addresses many of the shortcomings of existing lifting devices. The long-standing issue with lifting devices is pain.

However, Therf features a differentiated cooling system. People who receive Therf lifting commonly describe it as “warm and cold at the same time.” This may sound strange, but Therf delivers a cooling pulse each time a shot enters the skin tissue. Newer devices do offer notably different technology, don’t they?

Third, the treatment takes little time.

As mentioned earlier, Therf features a differentiated cooling system. Some of you may have already inferred this, but Therf is also a lifting treatment that does not require a numbing process.

Since no numbing process is needed and the treatment takes about 30 minutes for 600 shots, Therf is also convenient to receive during your lunch break.

Yes, today I introduced two lifting devices for those who do not have much time to spare.

When dry weather combines with work-related stress, your skin condition may deteriorate quickly, so please make sure to pay attention to hydration and moisturizing products.

Before looking into Hongdae Shrink or other lifting treatments, you should first reflect on your own lifestyle habits.

It would not be too late to look into “lunchtime lifting” devices after that, right?

I will wrap up here, hoping this information is helpful to those looking into Hongdae Shrink.

This was 차이의원, customizing your beauty. Thank you.
