Shurink vs Sofwave:
Comparing Ultrasound Technologies for Facial Firmness
November 3, 2026
Both use ultrasound, but Shurink (Shurink Universe) is a HIFU device that focuses energy at multiple depths , including the deeper SMAS layer, while Sofwave uses parallel ultrasound beams aimed at the mid-dermis . Shurink is usually cheaper and often used for regular lifting; Sofwave is pricier and targeted at skin tightening and fine lines. A doctor can recommend which depth and device fits your face.
Shurink vs Sofwave: key differences
Shurink and Sofwave are both ultrasound skin firming treatments offered at many Seoul clinics, but they are built around different ideas. Shurink follows the HIFU model of focusing energy into tiny points at chosen depths. Sofwave spreads energy through several parallel beams in a band within the dermis. These differences affect who each suits and how they feel.
| Feature | Shurink (Universe) | Sofwave |
|---|---|---|
| Type | HIFU (focused ultrasound) | Synchronous parallel ultrasound beams |
| Target depth | Multiple cartridges, e.g. 1.5, 3.0, 4.5 mm | Mid-dermis, about 1.5 mm |
| Main effect | Lifting and contour, plus skin firmness | Skin tightening, fine lines, texture |
| Cooling | Not a main feature | Integrated surface cooling |
| Comfort | Usually mild in continuous mode | Moderate; numbing often used |
| Typical price (2026) | ₩150,000–₩500,000 | ₩700,000–₩2,000,000 |
How does each ultrasound technology work?
Shurink: point-focused HIFU
HIFU concentrates ultrasound waves into a small focal point, much like a magnifying glass focuses light. At that point, tissue heats quickly to create a tiny coagulation zone, while surrounding tissue is relatively spared. By using different cartridges, clinics can work on the SMAS (deepest), the lower dermis and the upper dermis in the same session. Shurink Universe also includes a continuous mode for faster, smoother passes.
Sofwave: band-heating in the dermis
Sofwave's transducer emits several parallel beams that create a cylindrical heating zone in the mid-dermis. The focus is on stimulating collagen in the skin itself rather than lifting deeper structural layers. The surface is actively cooled, which is intended to protect the epidermis and allow higher energy in the target layer.
In practice, these technical differences mean Shurink sessions usually involve several cartridges, each set to a different depth, with shot counts split across them. A typical plan might use more shots at deeper depths along the jawline and fewer at shallow depths around the cheeks. Sofwave, by contrast, works at one main depth and the key variable is how many pulses are applied across each area. Asking the clinic to explain its plan in these terms will help you compare quotes fairly.
Which suits which face?
| Situation | Often considered | Why |
|---|---|---|
| Jawline definition, mild jowls | Shurink | Can reach deeper SMAS layer |
| Fine lines, crepey skin, enlarged pores | Sofwave | Targets mid-dermal collagen |
| Slim face, avoiding volume loss | Sofwave | Does not aim at deep fat |
| Regular maintenance on a budget | Shurink | Lower per-session cost |
| Neck and décolletage texture | Sofwave | Commonly used for skin quality |
| Moderate sagging plus texture | Combination | Different depths for different goals |
Because they act on different layers, some doctors consider them complementary rather than competitors. A combination plan, however, should be based on your individual assessment.
Age often influences which device is recommended. In general, people in their 20s and 30s with mild laxity may start with HIFU at moderate settings as a preventive measure, while people noticing crepey texture and fine lines may be guided towards dermal-focused treatments like Sofwave. These are only tendencies; skin thickness, facial fat and personal preference all affect the final recommendation.
What happens on the day?
- Registration. Bring your passport and complete a health questionnaire.
- Consultation. Agree on device, shot count and areas; ask for a written quote.
- Preparation. The face is cleansed and numbing cream may be applied, more often for Sofwave.
- Treatment. Gel is applied and the device is moved across target zones. Expect 20–45 minutes for a full face.
- Aftercare. Mild redness is typical. Use gentle skincare and sunscreen.
Results, downtime and side effects
| Stage | Shurink | Sofwave |
|---|---|---|
| Immediately | Mild redness, slight tightness | Redness, slight swelling |
| First days | Usually normal; mild jaw tenderness possible | Possible tenderness; makeup often next day |
| Visible change | Gradual over 1–3 months | Gradual over 1–3 months |
| Typical frequency | Every 3–6 months | Often once or twice a year |
| Uncommon side effects | Tenderness, swelling, rare nerve irritation | Tenderness, temporary marks |
Whichever device you choose, it helps to take your own before photos and compare them after two to three months, since the change is gradual. If you are a visitor, both treatments fit easily into a short trip because downtime is usually minimal. Do let the clinic know about any recent fillers, threads or other energy treatments, as these may affect timing and settings.
How much do they cost in Seoul?
| Treatment | Typical range (KRW, 2026) |
|---|---|
| Shurink Universe, ~300 shots face | ₩150,000–₩500,000 |
| Sofwave, full face | ₩700,000–₩2,000,000 |
| Ultherapy Prime (for comparison) | ₩700,000–₩2,000,000 |
| Consultation | Often free or ₩10,000–₩30,000 |
Prices are 2026 estimates in KRW and vary by clinic, area, device generation and the number of shots or lines. Always confirm the final written quote and whether VAT is included before treatment. Remember that the 10% VAT refund for foreign patients on cosmetic procedures ended on December 31, 2025.
Many clinics offer Shurink packages, such as 3 or 5 sessions, at a reduced per-session price.
The gap in price reflects device and consumable costs as much as anything else. Shurink cartridges are relatively inexpensive, which is why the treatment is often offered at accessible prices and in multi-session packages. Sofwave transducers carry a higher cost, so sessions are priced closer to premium HIFU. When comparing quotes, confirm the number of shots or pulses, the areas included (face only, or face and neck), whether numbing cream is included, and whether the price shown already includes VAT.
How to choose between them and a clinic
- Define your goal — Lifting contour points towards HIFU; skin quality points towards Sofwave.
- Ask about depths — For Shurink, ask which cartridges and how many shots per depth.
- Confirm genuine consumables — Ask whether cartridges or tips are genuine and new.
- Check doctor assessment — Ensure a doctor examines your face before treatment.
- Location and English — Gangnam and Sinsa–Apgujeong–Cheongdam have many English-friendly clinics.
Clinics offering Shurink are found in almost every Seoul neighbourhood, while Sofwave is more often available in clinics around Gangnam, Sinsa–Apgujeong–Cheongdam and other central areas. Many clinics accept WhatsApp, KakaoTalk or Line messages, so you can request a written quote before booking. Keep a copy of quoted prices, shot counts and areas so you can compare clinics clearly.
Frequently asked questions
Is Sofwave stronger than Shurink?
Not exactly. They target different layers. Sofwave focuses on the mid-dermis for skin tightening, while Shurink can reach deeper layers for lifting. Strength depends on settings and goals.
Can Shurink and Sofwave be done together?
Some clinics combine them because they work at different depths. A doctor will decide whether this is appropriate and how to space the treatments.
Which is better for a slim face?
Sofwave is often preferred because it does not aim at deep fat. However, Shurink settings can also be adjusted. Discuss with your doctor.
How long do results last?
Shurink is commonly repeated every 3–6 months and Sofwave once or twice a year. Results vary between individuals.
Is there any downtime?
Usually minimal. Expect mild redness for a few hours and possible tenderness for a few days.
Do I need numbing cream?
It is often used for Sofwave and sometimes for Shurink. The clinic will offer it if appropriate.
