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!
