Hey sisters in Taiwan, if you’ve been searching on Google lately for things like “top medical beauty treatments in South Korea, prices for radiofrequency treatments in South Korea, how effective ultrasound treatments are in the US, does OligioX hurt, and how long does the effect of Sofwave last?” then this article is exactly what you need — we’re sharing everything openly without holding back. Straight answer: Radio waves, sound waves, and Sofwave work at different depths in the skin. For mild sagging, radio waves or Sofwave can be chosen, while sound waves (such as Ultherapy Prime) are recommended for moderate to severe sagging. Clinics in South Korea often use a combined approach involving ONDA, sound waves, and radio waves to achieve the best results. The final choice should be made by a doctor based on an individual’s skin condition and budget.

How to choose an RF wave? First, consider your skin condition and budget.

Why do so many people fly to South Korea for Botox injections?

To be honest, in Taiwan, getting a Phoenix 900 treatment costs over 100,000 New Taiwan Dollars, while in South Korea it’s half that price. Moreover, Dermatology clinics in South Korea use a “layered treatment approach” rather than just one single treatment. Doctors will assess your facial structure, fat thickness, and whether the skin is sagging or loose, then select the appropriate device for you. This is exactly what makes medical beauty treatments in South Korea offer the best value for money.

This article is here to answer the most common questions people have: “How should I choose between different radiofrequency devices for cosmetic treatments in South Korea? Which device is best for reducing fat around the mouth? Is ONDA effective for treating Double Chin?”

I. Understand in 3 seconds: What’s the difference between radio waves, sound waves, and Sofwave?

Stop getting confused by nouns—just remember this:

U.S. ultrasound therapy works by lifting the skin. It reaches down to the SMAS fascia layer at a depth of 4.5 mm—exactly the layer that is lifted during facelift surgery. This treatment helps lift sagging skin around the mouth and the jawline upward.

Radio waves = tightening the skin. Products like Phoenix Radio Waves and OligioX Ultra Perfect Radio Waves target the dermis layer, heating up the loose Collagen to trigger contraction and regeneration, resulting in plumper and firmer skin.

Sofwave is like a hybrid device that gets stuck in between other treatments. It uses ultrasound energy, but it penetrates to a depth of 1.5 mm in the middle dermis layer, just like radio waves do. As a result, it not only provides lifting effects but also helps tighten the skin and shrink Pores.

ONDA hyper-microwave = removing illegal structures. It’s specifically designed to dissolve fat, making it an excellent solution for Double Chin, baby fat, and butterfly arms.

IV. FAQ Answers

Q: Can radiofrequency and ultrasound treatments be done together? Will it be too stimulating?
No, and they must be used together. In South Korea, the standard treatment approach these days is a “sandwich” method: ONDA for edge treatment (fat melting) → American ultrasound for underlying layer treatment (fascia tightening) → radio wave layering for skin firming, which delivers the most comprehensive results.

At DAN-A Dermatology in Myeongdong, we insist on using only genuine probes. You can verify this by scanning a QR code on site, and the probe will be removed right there after use—making Taiwanese customers feel completely at ease.

Q: How long does it last after the procedure?
Ultrasound waves, radio waves, and Sofwave all help stimulate the Collagen regeneration process. Effects can be felt after 1 month, with the best results appearing after 2–3 months. ONDA, on the other hand, helps smooth out contours after 2–4 weeks of fat metabolism.
