Online, you often see terms like “Ulthrea,” “second-generation American HIFU,” and “American-style HIFU” used interchangeably. Many people assume these refer to three different devices, but that’s not the case at all. Let’s start with the conclusion: These three terms mostly refer to the same type of second-generation focused ultrasound lifting device developed in the U.S. It’s just that different clinics use different translation conventions. You must confirm the actual model and whether it’s genuine directly with the clinic before making your appointment.

What exactly is this device?

The principle behind these devices is to use focused HIFU energy to penetrate deep into the skin and stimulate the production of new Collagen, thereby achieving a lifting and firming effect. Terms like “HIFU” and “ultrasound” are commonly used in the industry to refer to this type of device, while “American version” or “USA-made” is used to indicate that the device was developed and produced in the United States, setting it apart from some alternative models offered by South Korea-based manufacturers.

Is it the same device as the US version of the second-generation ultrasound?

To be honest, in most cases these three terms actually refer to the same type of second-generation HIFU lifting device made in the U.S. However, since there’s no unified official translation in Chinese, different clinics and beauty industry writers use varying terms online, which can make it hard to determine whether they’re referring to the exact same device. When choosing a clinic, don’t rely solely on its name—instead, ask clearly about the device’s official model, manufacturer certification, and source of importation to ensure you’re getting a genuine product.

What’s the difference between these kinds of HIFU lifting devices and the ultrasonic devices made in South Korea?

Most of these U.S.-made devices are genuine products developed by manufacturers in the United States, with long-term clinical data supporting their energy delivery efficiency and safety. The Sofwave devices made in South Korea, on the other hand, are alternative models developed by local South Korean firms; they tend to be more affordable, but their certification status and duration of clinical data collection are relatively shorter. Differences may exist between the two in terms of energy probe design, treatment depth, and recommended treatment sessions, and the results and duration of effects can also vary depending on individual skin conditions.

Who is a good candidate for this type of lifting ultrasound treatment?

Those whose skin has started to show mild sagging, deeper Nasolabial Fold Correction, and less defined facial contours but who are not yet ready for surgical procedures usually consider these types of ultrasound treatments. Pregnant women, those with inflamed or wounded skin, or those who have recently undergone other invasive treatments are advised against trying these methods right away. Whether it’s suitable for you must be determined through a personal consultation with the clinic director—don’t make decisions on your own.
