Sofwave in Korea: what it treats at 1.5 mm, how a session runs, and who it fits
In short Sofwave in Korea is an ultrasound treatment that works in the shallow dermis, the layer where fine lines begin, rather than in the deep fascia. At Symphony Skin Clinic in Seoul a session runs within 30 minutes under topical cream, and normal activity usually resumes the same day.

Most people who search sofwave korea have heard it called a gentler HIFU and want to know what that means for their own skin. Our Sofwave treatment page shows the device and the areas we treat. This guide answers the questions in the order they usually come up.
It covers what Sofwave does at 1.5 mm, how a session runs at our clinic, and who it fits. It also sets it next to Ultherapy and Thermage. If cost is your first question, how the Sofwave price in Korea is set is a separate guide.
What Sofwave is, in plain terms
Sofwave delivers ultrasound in parallel beams rather than focusing it on one deep point. The energy reaches the dermis at 1.5 mm and forms coagulation zones there. That prompts collagen to regenerate in the layer where surface firmness sits.
Each shot forms seven cylinder-shaped thermal zones. The manufacturer describes one cylinder as covering what several conventional HIFU focal points would, so a single shot treats a wide area evenly.
The epidermis is cooled throughout the session, so heat stays in the dermis and the surface is protected. Sofwave is an FDA and CE cleared ultrasound device.

How a Sofwave session runs at Symphony in Seoul
If you are planning Sofwave in Seoul, the visit is short. The order below is how a session runs at our clinic.
- Consultation. The doctor who assesses your skin writes the plan area by area, before the first shot.
- Preparation. Topical anesthetic cream is applied to the areas being treated.
- Treatment. The session takes within 30 minutes, with the epidermis cooled throughout.
- After. Swelling and flushing are usually minimal, and normal activity resumes the same day.
The same doctor performs the session and answers your follow-up questions after you fly home. You can see who treats patients on our doctors page.
Who Sofwave fits, and when we suggest something else
Sofwave is aimed at surface firmness, including skin too thin for deep lifting. It is not a substitute for deep structural lifting.
- Fine lines around the eyes: crow's feet and lines on thin eyelid skin, at the outer corners and under the eyes.
- Neck lines: horizontal and vertical lines on sensitive neck skin.
- Forehead, glabella, mouth corners and nasolabial area: fine lines that follow a loss of superficial firmness.
- Cheeks, cheekbone line and jawline: contour lines that have blurred as firmness declined.
- Structure that has already descended: this sits deeper than 1.5 mm, so we will say so and plan with a different device.
Sofwave carries a low pigment burden, so a wide range of skin types can be treated. Whether it suits your skin is still confirmed in person at consultation.
Before, during and after Sofwave treatment in Korea
| When | What to expect |
|---|---|
| Before | Consultation, a written plan for each area, then topical cream |
| During | Within 30 minutes, with the epidermis cooled throughout |
| Right after | A mild tightening may be felt. Swelling and flushing are usually minimal |
| Weeks 4 to 12 | Collagen regeneration progresses, and lines and firmness improve gradually |
Response varies between individuals. This is the pattern we describe at consultation.
Because swelling is usually minimal, a Sofwave treatment in Korea fits into a short trip. We still confirm your flight dates at consultation, so nothing that needs time is left for your last day.
Whether and when to repeat Sofwave is decided with your doctor once the 4 to 12 week window has passed, not on a fixed schedule. Symphony is on the second floor of the Sinsa Hill Building in Gangnam, and directions from Sinsa Station are on a separate page.
Sofwave vs HIFU, Ultherapy and Thermage
Conventional HIFU concentrates energy at 3 to 4.5 mm in the SMAS fascia, to pull up structure that has descended. Sofwave stays at 1.5 mm in the dermis. It is chosen for a different problem, not as a milder version of the same one.
| Sofwave | Ultherapy PRIME | Thermage FLX | |
|---|---|---|---|
| Energy | Parallel ultrasound (SUPB) | Focused ultrasound | Monopolar radiofrequency |
| Target layer | Dermis, 1.5 mm | SMAS, 3.0 or 4.5 mm (1.5 mm eye tip) | Dermis |
| Session | Within 30 min | 30-90 min | About 30-40 min |
| Downtime | Same-day return | Same-day return | Same-day return |
| Suited to | Fine lines and thin skin | Structure that has descended | Overall firmness and texture |
Based on each device's specifications as set out on our treatment pages. Results and recovery vary between individuals.
Ultherapy suits laxity in the deeper support layer, and our Ultherapy guide explains how that depth is checked on live imaging. For skin that has lost firmness rather than volume, Thermage FLX shot counts and pricing shows how that device is planned.
The three work at different depths, so a combined plan is common. Choosing a Sofwave clinic and device in Korea walks through that decision, and our lifting treatments overview lists every device we use.
Questions patients ask us
What is Sofwave used for?
Sofwave is aimed at surface firmness: fine lines around the eyes, neck lines, and lines on the forehead and around the mouth. It is not a substitute for deep structural lifting.
Is Sofwave in Seoul the same as HIFU?
No. Conventional HIFU focuses energy at 3 to 4.5 mm in the SMAS fascia. Sofwave delivers parallel ultrasound to the dermis at 1.5 mm, so it treats a different layer.
Does Sofwave hurt?
Sofwave cools the epidermis throughout, so the discomfort is lower than with conventional HIFU. Topical cream is standard, and how it feels still varies between people.
When will I see a change?
A mild tightening may be felt right after the session. Lines and firmness then improve gradually between weeks 4 and 12 as collagen regenerates, and timing varies between individuals.
Is there downtime after Sofwave treatment in Korea?
Swelling and flushing are usually minimal, and normal activity resumes the same day. We still check your flight dates at consultation.
Can I combine Sofwave with Ultherapy or Thermage?
Yes. They work at different depths, so a combined plan is common. Which combination suits you, and in what order, is decided with your doctor at consultation.
