ULTLINE uses focused ultrasound at five depths, from 1.5 to 13 mm, to target tissue from the dermis to subcutaneous fat. One device provides facial tightening and abdominal circumference reduction. We apply topical anesthesia before treatment.
For concerns about both facial sagging and abdominal fat, we can plan treatment with a single system.

The right depth
makes a difference to
every detail
ULTLINE is a fifth-generation HIFU system. Focused ultrasound concentrates energy at a selected depth to form precise thermal coagulation points. Five cartridge depths let your doctor target the dermis, SMAS or subcutaneous fat according to the area and concern.
The line handpiece addresses facial firmness and contours. For larger areas such as the abdomen, the 13 mm Ultra handpiece combines circumference reduction with skin tightening.
Focused ultrasound creates thermal points in the target layer, contracting tissue and tightening loose skin.
The deepest facial cartridge targets the SMAS, supporting and defining the jawline and facial outline.
Four facial cartridge depths let your doctor address the dermis and fascial layer separately, focusing on where sagging begins.
Firmness improves over time as ultrasound heat stimulates new collagen in the dermis.
The dedicated body handpiece focuses ultrasound heat in subcutaneous fat to reduce abdominal circumference.
Two Ultra handpieces can work simultaneously, delivering heat evenly over a larger area to tighten loose abdominal skin.
Results depend on planning and technique. At Dong-An Joongsim Clinic, a doctor conducts your consultation and performs the procedure, with time to assess your individual concerns.
Your doctor chooses among cartridges from 1.5 to 13 mm according to skin thickness and the cause of sagging. Shallower cartridges address dermal firmness; the 4.5 mm cartridge targets the SMAS for contouring.
The system includes both a facial line handpiece and a 13 mm body handpiece. Your doctor can assess facial laxity and abdominal circumference together and plan treatment on one system.
We take time with every patient. Your consultation and treatment are handled by a doctor; a patient coordinator only helps with pricing.
They took my concerns about pain seriously
Pain was my biggest worry before ULTLINE. I told them I was nervous, and we started after applying numbing cream. They paid attention to the things I was worried about, which put me at ease. They said results could take time, so I’m waiting before judging the outcome.
It felt manageable after the anesthetic
I was tense because I thought ULTLINE might hurt, but after the anesthetic, the sensations weren’t too strong. It felt more comfortable than another ultrasound treatment I’d tried. Still, comfort and visible results are different things, so I’m giving it time.
The aftercare was explained clearly
I mentioned my worries about pain during the consultation. Throughout treatment, they were considerate of those worries, which helped me relax. Afterward, they explained the precautions in detail. I’m waiting a little longer to see how the results develop.
Knowing what to expect helped me relax
After ULTLINE, I’m following the progress they described rather than deciding right away whether it worked. I was afraid of the pain, but talking about it and preparing beforehand helped me relax. They explained that redness could occur, and I’m following the aftercare advice they gave me.
How does one device treat different layers? Four steps take treatment from depth selection to collagen renewal.
Your doctor chooses the cartridge for the area and cause of sagging.
Focused ultrasound forms precise thermal coagulation points in the selected layer.
The line handpiece contracts tissue, producing an initial tightening effect.
Ultrasound heat stimulates collagen production, so firmness develops over time.
Similar-looking sagging can have different causes and tissue characteristics. Your doctor examines the face and body, then selects the necessary depths from the superficial skin to the fat layer.
The 1.5 and 2.0 mm cartridges address firmness in shallower layers.
The 3.0 mm cartridge stimulates tissue that supports skin structure.
The 4.5 mm cartridge targets the supporting fascia for contour lifting.
The 13 mm body handpiece targets abdominal fat to reduce circumference.
Layer thicknesses are simplified for illustration. Actual depths vary with the treatment area and skin thickness.

Treatment for a double chin depends on whether the main cause is fat beneath the chin or sagging skin and fascia.
The doctors at Dong-An Joongsim ClinicResults depend on planning and technique. Check who conducts your consultation and procedure, whether authentic devices and supplies are used, and whether treatments can be combined for your needs. At Dong-An Joongsim Clinic, a doctor handles both consultation and treatment, with time to discuss your individual concerns.
The system has a facial line handpiece and a body Ultra handpiece, allowing both areas to be treated with one system. We discuss the specific schedule during consultation.
Two Ultra handpieces can be used simultaneously to treat larger areas efficiently.
We use topical anesthesia. The body handpiece also has two-stage cooling to help reduce discomfort.
The 1.5 and 2.0 mm cartridges target the dermis; 3.0 mm reaches the deeper dermis and upper SMAS; 4.5 mm targets the SMAS; and 13 mm targets subcutaneous fat. Your doctor combines the depths needed for your concerns.
Facial cartridges from 1.5 to 4.5 mm create thermal points from the dermis to the SMAS, helping tighten loose skin and define the jawline. An initial tightening sensation may follow treatment, with firmness developing as collagen forms. The 13 mm body handpiece targets abdominal subcutaneous fat to help reduce circumference and tighten the area.
