I. Which is better—the first or second generation of HIFU in South Korea? Here’s the answer in 30 seconds.
- Key takeaway: The first generation of HIFU (Ultherapy Classic) and the second generation (Ultherapy PRIME) share the same underlying technology—MFU-V focused ultrasound combined with DeepSEE real-time imaging. The second generation isn’t a complete replacement but rather an upgraded version that offers an improved experience.
- Key upgrades in the second generation: processing speed increased by about 10 times, image clarity improved by 50%, discomfort reduced by roughly 30%, treatment time shortened by about 20% (to around 45–60 minutes), plus the addition of QR code anti-counterfeiting features and new indications for abdominal and forearm areas.
- Duration of effect: About 6–12 months for the first generation; around 12–18 months for the second generation, with a maximum duration of up to 2 years.
- South Korea 2026 Market Trends: First-generation 300 units cost around ₩1.5–1.75 million (NT$34,500–40,250); second-generation 300 units in Gangnam cost around ₩1.8–2.2 million (NT$41,400–50,600), while those available in Busan cost ₩1.46 million (NT$33,580).
- My recommendation: If your budget is limited and you’re satisfied with the first generation, going with that one will suffice. If you’re afraid of pain, want to save time, and are looking for more stable performance and a longer lasting effect, go for the second generation.
In this article, I’ve compiled information on the public pricing of HIFU treatments at several Dermatology clinics in South Korea for 2026, along with the official specifications and actual user experiences for both the first-generation and second-generation models. HIFU isn’t a traditional facelift surgery—it uses focused ultrasound to deliver energy to the SMAS fascia layer, stimulating collagen contraction and thus achieving a “non-invasive lifting” effect. Below, I’ll clarify the differences between the two generations, their prices, and how to decide whether to include it in your itinerary when visiting Seoul.
II. What is HIFU? Similarities in core technology between the first and second generations
Let’s first clarify what exactly HIFU is. Its full name is “Ultherapy,” and it utilizes MFU-V technology (Micro-focused Ultrasound with Visualization), combined with DeepSEE real-time ultrasound imaging, which allows doctors to see the subcutaneous layers during treatment and deliver energy precisely to the SMAS fascia layer at 4.5mm depth. This aspect remains exactly the same in both the first-generation and second-generation versions—in other words, the second generation doesn’t involve a different type of energy or a complete reinvention; rather, it improves the user experience and stability based on the “same underlying principle.”
How does it work to “lift” the skin? Ultrasound waves penetrate the epidermis without damaging the surface, creating thermal coagulation points at the target depth. This triggers the body’s natural repair mechanisms, tightening the collagen fibers. Over time—typically 2 to 3 months—the facial contours gradually become firmer. Since the procedure is non-invasive, there is only mild redness and swelling after treatment, allowing most people to wear makeup and go out right away. This is exactly what sets it apart from surgical facelifts and thread lifting. Those interested in other anti-aging options can also check out our guide on Radiesse prices and treatment areas in South Korea, where we compare the approaches of “stimulating collagen” and “filling for support.”
Evidence 1: The technical principles behind MFU-V and DeepSEE are based on the official instructions provided by Ultherapy’s manufacturer (Merz / formerly Ulthera, Inc.) as well as information approved by the U.S. FDA. The depth of action for the SMAS layer is explicitly stated to be 4.5mm by the manufacturer. Sources: Ultherapy’s official technical documents and compiled data from U.S. FDA medical device approvals.
III. Real-World Experiences and Positioning of the First Generation of HIFU (Ultherapy Classic)
The first generation of HIFU is the version that first became well-known as the “Ulthrea.” It started to gain popularity in South Korea, Taiwan, and Hong Kong around 2013. I once had a treatment with the first-generation device, using 300 shots, in Seoul. What I experienced was a noticeable “tingling sensation” when the energy was delivered to the temples and jawline; some people found it painful, which is why most clinics in South Korea offer numbing creams or oral pain relievers. The entire treatment takes about 60–90 minutes. Right after the procedure, there’s a slight sense of firming in the facial contours, but it takes 2–3 months to see significant tightening effects.
The advantage of Generation 1 CDU devices is their proven track record in the market, transparent pricing, and the wide availability of clinics offering them. As legitimate medical devices, they have enjoyed over a decade of clinical use, ensuring their safety. However, they tend to cause more noticeable pain, have lower image resolution, and rely on the doctor’s skill and experience to control energy output, resulting in significant variations in performance across different clinics and doctors. For those who are budget-conscious and want to try “non-invasive lifting” first, Generation 1 CDU remains a practical choice for getting started.
IV. What improvements has the second generation of HIFU (Ultherapy PRIME 极透＋) brought?
The official name of the second generation is Ultherapy PRIME. It received FDA approval in the United States in 2024 and was introduced to Taiwan in 2025, with legitimate clinics in South Korea also starting to offer it one after another. The biggest difference between it and the first generation lies not in the “energy mechanism,” but rather in a complete overhaul of the “system and user experience.”
- 10x Faster Processing: The next-generation processor enables instant image rendering and energy optimization, eliminating any lag or waiting time.
- Crisper images (+50%): The DeepSEE screen has been upgraded to 19 inches with a resolution increase of around 50%, allowing doctors to more easily identify blood vessels and layers while avoiding dangerous areas.
- Pain reduced by about 30%: The energy output curve has been recalibrated, with most users reporting that the stinging sensation is significantly milder compared to the first generation.
- Time saved by about 20%: The entire treatment is reduced to around 45–60 minutes, making it more convenient for those on a tight schedule.
- QR Anti-Counterfeiting: Each probe comes with a unique QR code that allows you to verify its authenticity and usage history, reducing the risk of using non-original probes.
- Expanded indications: Beyond the face, it now offers firming benefits for other body areas such as the abdomen and forearms, providing more diverse treatment options.
In short, the second generation offers “the same science behind it, just a better driving experience.” If you’re sensitive to pain, short on time, or prefer having clearer imaging assistance from your doctor, the improved feel of the second generation is truly noticeable. It doesn’t “replace” the first generation—it simply provides an additional option for those with more budget.
Data Point 2: The second-generation Ultherapy PRIME received FDA approval in the United States in 2024 and was introduced to Taiwan in 2025. Comparative data on processing speed, image resolution, discomfort level, and treatment time are based on specifications publicly released by the manufacturer. Sources: Official product launch materials from Ultherapy PRIME, and summaries of medical device approval announcements from Taiwan’s Ministry of Health and Welfare.
V. HIFU Generation 1 vs Generation 2: A Comparison of 6 Key Differences
Create a comparison table of the 6 key factors that most significantly impact both the experience and budget, so you can instantly see where the differences lie:
| Comparison points | First-generation HIFU (classic model) | HIFU 2nd Generation (PRIME Extreme+) |
|---|---|---|
| Listing/Introduction | Became widespread around 2013 | Approved by the U.S. FDA in 2024, to be introduced in Taiwan in 2025 |
| Core Technology | MFU-V + DeepSEE | MFU-V + DeepSEE (same principle) |
| Images/Screens | Older screens with lower resolution | 19-inch screen, 50% higher clarity |
| Pain sensation | Obviously, anesthesia is often needed. | Approximately 30% reduction – acceptable to most people |
| Duration of the treatment | About 60–90 minutes | Approximately 45–60 minutes (20% time savings) |
| Duration of Effect | About 6–12 months | Approximately 12–18 months (up to 2 years) |
| Anti-counterfeiting/Indications | Basic anti-counterfeiting, focused on the face | QR anti-counterfeiting feature, added abdomen/forearm options |
This table also shows one thing: the difference in their “maximum effectiveness” isn’t as significant as the price gap. The real differences lie in comfort, stability, and time savings. If budget is a concern, the first generation is more than sufficient; if you want an optimal experience, then consider the second generation.
VI. Overview of HIFU Prices in South Korea for 2026 (First/Second Generation)
The prices listed below are based on the Korean won rates published by clinics in South Korea for 2026. I’ve converted them into Taiwanese dollars using the rate of ₩10,000≈NT$230 for reference. Most quotes don’t include a 10% VAT, and the actual cost may vary depending on the doctor’s expertise, number of sessions, and treatment area. Be sure to check the final total amount before placing an order.
| Project | Korean Won (public rate) | TWD reference |
|---|---|---|
| First-generation HIFU: 100 shots | Starting from ₩400,000 | Starting from NT$9,200 |
| First-generation HIFU: 300 shots | ₩1,500,000 – 1,750,000 | NT$34,500 – 40,250 |
| First-generation HIFU: 600 shots | ₩2,900,000 | NT$66,700 |
| HIFU 2nd Generation – 300 shots (available at Busan’s The First and others) | Starting from ₩1,460,000 | Starting from NT$33,580 |
| HIFU 2nd Generation – 300 Sessions (Gangnam Shopping District) | ₩1,800,000 – 2,200,000 | NT$41,400 – 50,600 |
A few observations: In outer commercial areas like Busan, the price per session for the second-generation version already overlaps with that of the high-end first-generation option. If a promotional deal is available, the second generation might not necessarily be more expensive; however, in top-tier areas such as Gangnam, it usually costs significantly more. The number of shots (100/300/600) directly determines the treatment area—100–300 shots are common for partial facial refinement, while 600 shots are typically used for the entire face plus neck. Those looking to refine their facial contours can also compare the results of HIFU treatments with those offered by TS Plastic Surgery for contour shaping, to determine which approach—non-invasive lifting or structural sculpting—is better suited to their needs.
Data Point 3: The price ranges are based on the publicly available price lists of various Dermatology clinics in South Korea for 2026, including the special price of ₩300 for treatments at The First Medical Group’s second-generation clinic in Busan, as well as the regular prices at clinics in the Gangnam area. The exchange rate used is ₩10,000≈NT$230. Sources: Publicly available price lists of medical aesthetics services in South Korea and official promotional pages of various clinics.
VII. How should I choose between the first-generation and second-generation HIFU?
Simplify your options into three choices and match them to your situation:
- One generation is enough: if you have a limited budget, are doing non-invasive lifting for the first time, aren’t sensitive to pain, or want to try the results first. The first-generation products are well-established in the market, with numerous clinics offering them at favorable prices.
- The second generation is a better choice: for those who are afraid of pain, have limited time, prefer doctors with clearer imaging assistance, or are looking for longer-lasting results (12–18 months). If you come across promotional prices at shopping centers in areas like Busan, the cost of the second generation might not necessarily be higher than that of the first generation.
- Choose the doctor first, then the device: The effectiveness of HIFU depends heavily on “who performs the treatment, how deep it goes, and how many sessions are done.” Instead of getting stuck on different generations of devices, it’s better to first confirm whether the clinic is officially authorized by the manufacturer and whether the doctor has sufficient experience with this treatment before deciding on a specific device.
My practical advice: For those doing this for the first time with a limited budget, start with Generation 1 at 300 shots. If you’ve tried Generation 1 and found it too painful to go back, or if you have more budget and want to get it done in one go, go straight for Generation 2. No matter which generation you choose, it’s recommended to bring front/side photos for a in-person consultation, so the doctor can determine how many shots and at which layers to administer.
VIII. 8 Things to Know About HIFU
Both the first generation and the second generation come equipped with MFU-V+DeepSEE. The second generation isn’t just about an upgraded power source—it represents a comprehensive improvement in processing speed, imaging quality, comfort levels, and time efficiency. Don’t fall for the misconception that “a newer generation means better results.”
The first generation requires anesthesia, and some people experience stinging sensations; pain levels are reduced by about 30% with the second generation. For those who are sensitive to pain, the difference in comfort is truly noticeable with the second generation.
The first generation lasts about 6–12 months, the second generation about 12–18 months, with a maximum duration of up to 2 years. If you want to minimize visits to the clinic, the longer-lasting effect of the second generation makes it more cost-effective.
100–300 shots for partial treatment; 600 shots are required for full face + neck. When comparing prices, make sure to ask clearly “how many shots are included and which areas are covered.”
The listed price often doesn’t include 10% VAT, so make sure to confirm when comparing options whether the total cost covers the consultation fee and anesthesia.
The second-generation probe comes with a unique QR code to verify its authenticity. For both the first and second generations, it’s recommended to ensure you’re using original probes to avoid non-genuine replacement parts.
It’s a non-invasive procedure that allows you to wear makeup right away, though results take 2–3 months to become noticeable — you won’t see immediate firming effects. Avoid alcohol and saunas for a week after the treatment, and make sure to use plenty of moisturizer and sunscreen.
Suitable for relaxation, blurred contours, and mild to moderate sagging. Those who are pregnant, have severe heart disease, or have significant inflammation at the injection site or prior filler treatments should consult a doctor first.
