Sofwave in Seoul: Ultrasound Tightening for Lines and Laxity
The short answer
Sofwave is an ultrasound skin-tightening treatment that heats the mid-dermis at about 1.5 mm with parallel beams to stimulate collagen and soften fine lines and laxity. In Gangnam a full-face session typically costs ₩1,000,000–₩3,500,000, takes 30–45 minutes, and has little downtime beyond brief redness. Results build over about three months and typically last around a year.
Key facts

- Depth: mid-dermis, about 1.5 mm
- Treats: fine lines, mild laxity, crepey skin, brow and jawline
- Session time: 30–45 minutes
- Downtime: minimal; mild redness for a few hours
- Typical Seoul price: ₩1,000,000–₩3,500,000 full face
How Sofwave works
Sofwave uses a technology called SUPERB, short for Synchronous Ultrasound Parallel Beam. Seven parallel ultrasound beams heat a band of tissue in the mid-dermis, at about 1.5 mm depth, where collagen and elastin fibres sit. A built-in cooling system protects the skin surface. The heat triggers new collagen production over the following weeks, which tightens skin and softens fine lines.
Unlike traditional HIFU, which creates focused points deeper in the SMAS, Sofwave targets a wider, shallower zone. That makes it particularly suited to skin quality and fine lines rather than deep lifting.
Sofwave vs HIFU vs RF
| Feature | Sofwave | HIFU (Ultherapy, Shurink) | Monopolar RF (Thermage) |
|---|---|---|---|
| Main depth | Mid-dermis | SMAS and deep dermis | Dermis |
| Best for | Fine lines, laxity | Lift, jowls | Tightening, crepiness |
| Comfort | Moderate, with cooling | Moderate to strong | Moderate |
| Session time | 30–45 min | 30–90 min | 45–90 min |
Some patients combine Sofwave with HIFU so both deep lift and surface tightening are addressed. Compare details on our Ultherapy and Thermage pages.
Who Sofwave suits
- Adults with fine lines and early to moderate laxity
- People who want firmer skin without injections
- Patients with thin faces who want to avoid volume loss from deeper HIFU
- Those wanting brow lift or jawline definition with no downtime
What a session is like
After cleansing and numbing cream, the applicator is placed on the skin in sections. Each pulse lasts a few seconds and feels hot, with built-in cooling. A full face takes about 30–45 minutes. Makeup can usually be applied right after.
Results timeline
Some patients notice smoother skin within days. The main tightening and line improvement develops over about 12 weeks as collagen forms. Results typically last around a year, and many people repeat annually.
Side effects
- Redness and mild swelling for a few hours
- Temporary tenderness
- Rarely, small grid marks that fade within days
Planning as a visitor
With minimal downtime, Sofwave suits any point in your trip, even just before your flight. Because results develop over months, take photos before treatment. For clinic options, see top Sofwave clinics in Myeongdong, and for alternatives read our guide to skin tightening without surgery.

Patient questions
Frequently asked questions
Does Sofwave hurt?
Pulses feel hot for a few seconds. Built-in cooling and numbing cream make it tolerable for most people.
