What Sofwave is and how it works

Sofwave is an energy-based skin tightening device developed in Israel. Instead of concentrating ultrasound into small focal points as micro-focused ultrasound does, it uses an array of transducers to send multiple parallel ultrasound beams into the skin at the same time. The company calls this SUPERB , short for synchronous ultrasound parallel beam technology. The beams create a band of controlled heating at about 1.5 mm, the middle of the dermis, where collagen and elastin fibres sit.

To protect the surface, the applicator has built-in cooling, which is why the epidermis usually stays intact. The heat triggers a wound-healing response, and over the next few months the dermis produces new collagen. According to the device's US 510(k) documents, the thermal effect is shallow and confined to the treatment zone, without coagulation below it.

This design makes Sofwave quite different from Ultherapy and HIFU, which can reach the deeper SMAS layer. In practice, Sofwave is best thought of as a dermal treatment for lines and early laxity rather than a deep lifting tool.

What Sofwave is cleared to treat

In the United States, the FDA has cleared Sofwave as a non-invasive aesthetic treatment to improve facial lines and wrinkles, to lift the eyebrow, and to lift lax submental (under-chin) and neck tissue in adults aged 22 and older. It is also cleared for short-term improvement in the appearance of cellulite. Clearance means the device met the FDA's requirements for these uses; it does not guarantee a particular result for every person.

Published clinical work on the technology reports improvement in fine lines and skin laxity with a good safety profile, and histology showing new collagen in the mid-dermis. As with any device, results vary with age, skin thickness, sun damage and lifestyle.

Is Sofwave available in Myeongdong?

Device availability changes between clinics and over time. Please ask us on WhatsApp whether Sofwave is currently available at the Obliv Myeongdong branch before you plan a trip around it. If it is not, we will tell you honestly and explain which option is closest for your concern, or what kind of clinic offers it.

For many people the underlying goal, smoother lines and a firmer brow or neck, can also be reached with treatments that are available at Obliv: Ultherapy or HIFU for lift, Thermage FLX or Thermage Eye for crepey skin and hooding, laser lifting for texture, and Botox for dynamic forehead and frown lines.

Sofwave compared with Ultherapy, HIFU and Thermage

The main difference is depth. Sofwave concentrates on the mid-dermis, so it is often chosen for fine lines and thin, crepey skin. Micro-focused ultrasound such as Ultherapy places heat points at several depths, including the SMAS, which matters when jowls and a softening jawline are the main concern. Monopolar RF heats a broad volume of dermis and fibrous septa for overall firmness.

In Seoul, many clinics combine tools layer by layer. At Obliv, our Skin Architecture method reads your concern as layers first, then chooses the energy and depth for each. See our guide to combination RF lifting for how this works.

Who is a good candidate

Sofwave-type treatment generally suits adults with fine lines, early skin laxity, mild brow heaviness or early softening under the chin. It is less suitable when the main problem is marked jowling or heavy loose skin, where deeper lifting or surgery is more effective.

Avoid treatment over open wounds, active acne cysts or infection, and tell your doctor about superficial fillers, implants or recent procedures in the area. Elective treatments are usually postponed during pregnancy and breastfeeding.

What to expect during and after treatment

Numbing cream is usually applied first. The applicator is moved across each zone in a set pattern while the cooling system protects the surface; most people feel brief, intense warmth with each pulse. A full face typically takes about 30–45 minutes. Immediately afterwards the skin may look red and feel warm, and mild swelling can last for a few hours or, occasionally, a day or two.

Most people can wear sunscreen and light makeup the same day. Results develop gradually, with clinical studies typically assessing improvement around 12 weeks after treatment. Daily sunscreen, a gentle routine and stable weight help maintain the result.

Planning a lifting treatment around a Myeongdong trip

Because dermal ultrasound and RF treatments have little visible downtime, they can be booked on almost any day of a trip, even the evening before shopping in Myeongdong. Obliv is between Myeongdong and Jongno, about a six-minute walk from Jongno 3-ga and Euljiro 3-ga stations and roughly 12–15 minutes on foot from central Myeongdong.

Send photos, your concern and your dates on WhatsApp. We will confirm what is available, suggest a realistic plan and give you a written quote. Korea's cosmetic-procedure VAT refund for foreign visitors ended on 31 December 2025; see prices and payment.
