What are the effects of Shurink and Doublo HIFU? Gangnam Station
Dr. Choi Dong-il explains the mechanisms and benefits of Shurink and Doublo HIFU lifting treatments at Gangnam Seoyeon Plastic Surgery.

What are the effects of Shurink and Doublo HIFU? Gangnam Station
This is Director Choi Dong-il.
We originally had the Doublo device at our clinic and used it well for three years, but we have now purchased the Shurink as our new model.

This is the banner we brought in this time.
This is what the machine looks like.
For reference, this is what the Doublo looks like.
Ultimately, both are High-Intensity Focused Ultrasound (HIFU) devices, so the mechanism behind the Shurink effect and the Doublo effect is the same. The differences lie in the depth the ultrasound reaches and the level of convenience for the practitioner.
The advantage of the Shurink we purchased this time is that the shot speed is fast and continuous shots are possible. This shortens the procedure time, making it more comfortable for both the patient and the practitioner.
Lifting is achieved by concentrating ultrasound at a depth of 1.5 to 4.5 mm beneath the skin to generate heat. To be more specific, it uses a mechanism where ultrasound is focused on the tissue after calculating the speed at which the waves reflect back. The resulting thermal energy from rapid vibrations either breaks down cells or causes them to shrink.
It essentially causes a type of thermal damage; you can think of it like the principle of a squid shrinking when it is grilled.

Generally, it seems that at least 300 to 400 shots are needed to see an effect, while exceeding 800 shots does not seem necessary.
Gangnam Seoyeon Plastic Surgery will strive to lead the way here at Gangnam Station. Come forth, my favorite muscular rabbit emoticon!

Frequently Asked Questions
What is the common principle of Shurink and Doublo lifting?
Both devices share the common principle of using High-Intensity Focused Ultrasound (HIFU). They create a lifting effect by concentrating ultrasound at a depth of 1.5 to 4.5mm within the skin, generating thermal energy that contracts the tissue.
What are the advantages of Shurink lifting compared to the existing Doublo?
Shurink's biggest advantage is its fast shot speed and the ability to perform continuous shots. This significantly shortens the overall treatment time, providing a much more comfortable environment for both the patient and the practitioner.
What is the appropriate number of shots for Shurink lifting treatment?
Generally, 300 to over 400 shots are needed to see proper results. However, it is recommended not to perform excessive treatments beyond 800 shots.
What effect does the thermal energy generated during ultrasound lifting have on the skin?
Thermal energy causes a type of thermal damage to skin tissue, breaking down or contracting cells. Similar to how a squid shrinks when grilled by heat, it improves skin elasticity.
