Short answer:
Ultherapy uses micro-focused ultrasound to heat the deep dermis and the SMAS, the same supporting layer a surgeon tightens in a facelift. Some people notice a slight lift right away, but the real result builds over 8–12 weeks as new collagen forms, peaks around 3 months and typically lasts about a year. In Gangnam, a full-face session typically costs ₩800,000–₩2,500,000 (about $570–$1,790).
How Ultherapy works
Ultherapy delivers focused ultrasound energy to precise depths, commonly 1.5 mm for the superficial dermis, 3.0 mm for the deep dermis and 4.5 mm for the SMAS. Unlike most other HIFU devices, it uses real-time ultrasound imaging so the operator can see the tissue layers before firing each line.
Each line creates tiny thermal coagulation points. The body treats them as micro-injuries and responds with new collagen and elastin. That repair process, not the heat itself, is what gradually tightens and lifts the skin, which is why results are delayed. See our Ultherapy guide
for device details.
Week-by-week timeline
Day 0 to day 3
Mild redness, swelling and tenderness are common, especially along the jaw. A small immediate tightening is sometimes visible, partly from swelling. Makeup is usually fine the next day.
Weeks 1 to 2
Swelling settles. Some people feel tingling or tenderness when pressing on the jawline or under the chin; this usually fades within a few weeks.
Weeks 4 to 6
Skin starts to feel firmer to the touch as early collagen forms. Changes are subtle in photos.
Weeks 8 to 12
This is the main result window. The brows may sit slightly higher, the jawline looks sharper and the area under the chin tighter.
Months 3 to 6
Results peak and stabilise. Most clinics take comparison photos at around 3 months.
Month 12 onward
Natural ageing continues, so the effect gradually softens. Many people repeat once a year or alternate with other lifting treatments.
Who gets the best results
- Mild to moderate laxity:
people in their late 30s to 50s with early jowls or a softening jawline usually see the clearest change.
- Good skin quality:
skin that still has some elasticity responds better.
- Realistic expectations:
Ultherapy cannot match a surgical facelift for heavy sagging.
If laxity is marked, see options for jowls and sagging.
What affects your results
- Number of lines:
clinics price by line count. Too few lines for the area can mean a weaker result, so compare line counts, not just prices.
- Depth mapping:
experienced operators adjust transducers to each zone and avoid nerves and thin areas.
- Comfort settings:
energy turned down too far to reduce pain may reduce effect.
- Lifestyle:
sun exposure, smoking, rapid weight loss and poor sleep shorten longevity.
Does it hurt?
Ultherapy can be uncomfortable, particularly over bony areas such as the jaw and forehead. Gangnam clinics typically apply numbing cream for 30–60 minutes and may offer oral pain relief. Newer Ultherapy Prime sessions are often described as faster. Speak up during treatment; the operator can adjust energy line by line.
Ultherapy price in Gangnam (2026)
- Ultherapy full face:
₩800,000–₩2,500,000 (about $570–$1,790), with many quotes near ₩1,650,000.
- Ultherapy Prime:
₩1,200,000–₩3,500,000 (about $860–$2,500).
- Shurink, a Korean HIFU alternative:
₩150,000–₩500,000 (about $110–$360).
- Thermage FLX, for surface tightening:
₩1,500,000–₩4,000,000 (about $1,070–$2,860).
In the US, a full-face Ultherapy session typically costs $3,000–$5,000, so Gangnam is often about 70% less. Ask how many lines are included and which areas are covered, and ask to see the device and transducers. See the Ultherapy cost guide.
Combining Ultherapy with other treatments
Gangnam clinics often pair Ultherapy with Thermage FLX, which tightens the more superficial dermis, or with skin boosters such as Rejuran for texture. Botox and fillers can be added, but filler is usually placed after HIFU or on a separate day. Read Ultherapy alone vs the Ultherapy and Thermage combination.
Aftercare
- Avoid saunas, hot yoga and intense exercise for 2–3 days.
- Use gentle skincare and daily sunscreen.
- Do not massage firmly over tender areas.
- Report any numbness or muscle weakness that does not improve to the clinic.
