# Sofwave in Seoul > Sofwave is a non-invasive ultrasound skin-tightening device that heats the mid-dermis with seven parallel, non-focused beams. The guides cover how it works, its US FDA clearances, who it suits, recovery, the published studies and what a session costs in Seoul. Sofwave Medical Ltd. of Israel makes the device and calls its technology SUPERB (Synchronous Ultrasound Parallel Beam). Seven transducers fire together at 10–12 MHz with a target treatment depth of about 1.5 mm in the dermis, creating separate cylindrical thermal zones that span roughly 0.5–2 mm and reach about 60–70 °C, while contact cooling and a real-time skin-temperature monitor protect the surface. It treats the dermis and does not remove fat. A session takes about 30–60 minutes; published protocols use about 3.0–4.2 J per pulse, two to three passes per area and roughly 150–200 pulses to cover both cheeks. US FDA 510(k) clearances by indication: - 9 September 2019, K191421: facial lines and wrinkles, when the device was named the Sofacia System - 15 November 2021, K211483: lifting the eyebrow and lax submental and neck tissue, ages 22 and older - 16 December 2022, K223237: short-term improvement in the appearance of cellulite - 28 August 2023, K231537: acne scars - 22 December 2023, K233104: upper-arm skin laxity, studied with two sessions 1–3 weeks apart and assessed three months after the final session In the 15-participant Gold and Biron study, mild redness and swelling resolved on their own, one case of mild facial peeling settled within three days and no serious adverse events were observed. Change is judged over months: some clinical studies followed outcomes for six months, an acne-scar case series for up to eight months and a biopsy study for up to ten months. [Delight Dermatology Clinic](https://hifuseoul.com/procedures/sofwave-seoul/) lists around KRW 2,000,000–2,200,000 per Sofwave session, with the final amount confirmed at consultation from the treatment area and agreed plan. At the [Federal Reserve’s 28 August 2026 rate](https://www.federalreserve.gov/releases/h10/20260831/) of KRW 1,379.41 per US dollar, that is about USD 1,450–1,595. ## Sofwave guides - [Sofwave in Seoul: price, results and choosing a clinic](https://sofwave-seoul.com/): Sofwave ultrasound skin tightening in Seoul: about KRW 2.0 to 2.2 million a session in Gangnam, how it works, who it suits, recovery and choosing a clinic. - [About the medical reviewer](https://sofwave-seoul.com/about-the-clinician/): Who medically reviews the Sofwave guides: a Korean Board-Certified Dermatologist, and what that specialist certification means in Korea. - [Sofwave aftercare and downtime: what the days after look like](https://sofwave-seoul.com/aftercare-downtime/): What is normal after a Sofwave session, how the result develops over months, what to avoid, and the signs that warrant contacting the clinic. - [Sofwave candidates and contraindications](https://sofwave-seoul.com/candidates-and-contraindications/): Who mid-dermal parallel-beam ultrasound suits, who is screened out at examination, and the safety categories a dermatologist checks before treating. - [Sofwave FAQ: cost, pain, results and recovery](https://sofwave-seoul.com/faq/): Direct answers to the questions patients ask before booking Sofwave in Seoul: session length, pain, timeline, duration, FDA clearances, price and combination with other treatments. - [Is Sofwave a Laser?
