Is the US version of the second-generation ultrasound effective? Based on actual cases treated at DAN-A’s clinic in Myeongdong, as long as the energy level, depth, and probe selection are appropriate, there won’t be the “mask-like” appearance or excessive stiffness rumored online. Instead, it gradually improves sagging jawlines. This article recounts the real-life journey of a client who went from hesitation to making the decision.
Jiaxin (a pseudonym), 38 years old, is a client who works in marketing in Hong Kong. She had been interested in the American version of the second-generation ultrasound treatment two years ago, but kept holding back due to negative reviews online claiming the results looked stiff and unnatural. It wasn’t until this year that she finally made up her mind to come to DAN-A in Myeongdong for an in-person consultation.

The official name for the American version of the second-generation ultrasound therapy is Ultherapy PRIME. By utilizing HIFU High Intensity Focused Ultrasound technology, it has gained great popularity among cosmetic clinics in South Korea and Hong Kong. Those looking to improve their jawline and Nasolabial Fold Correction often compare its effectiveness and safety with other devices.
Reason for hesitating for two years: fear of creating a “mask-like” effect
“My biggest worry is that after the treatment, my whole face feels stiff, making it look unnatural when I smile,” Jiaxin said during her initial consultation. This concern is actually quite common—many people still think of HIFU as a single session involving high-energy treatment applied uniformly across the entire face. But in reality, modern approaches adjust the combination of depth and energy levels based on each individual’s facial structure, skin thickness, and areas of sagging.
Clinic Conversation: How the Director Addressed His Concerns
The clinic director explained that Jiaxin’s main issues were sagging around the lower jaw line and Nasolabial Fold Correction area, while the elasticity of her mid-cheek region was still fairly good. Therefore, it was recommended to focus the treatment on lifting the lower jaw line through fascial layer manipulation, rather than applying high energy evenly across the entire face. This “zone-specific adjustment” approach is precisely what helps avoid a stiff, mask-like appearance—and it’s also why the genuine American-made device can achieve precise depth control.
Live recording of the injection process
The entire treatment takes about 70 minutes. Jiaxin described feeling a noticeable but tolerable warmth in the fascial layer, with the therapist adjusting the energy level based on her reactions in real time. There was no significant swelling on the day of the treatment; only slight redness on the skin. After applying a soothing mask, she was able to retouch her makeup and go out as usual, without experiencing the stiffness she had been worried about.
Post-surgery results and mindset transformation
About 4 weeks later, Jiaxin reported that a clear contour began to appear along her jawline, and her expression looked natural when she smiled—completely free from the “stiffness” she had been worried about before. During her follow-up appointment, she said, “What I was afraid of for two years turned out to be something related to cases that weren’t suitable for me; what really matters is finding the right energy level and depth for one’s own face.” This case also reminds us that the effectiveness of ultrasound therapy depends largely on pre-operative assessment and proper adjustment of energy levels, rather than just the device itself.
Frequently Asked Questions FAQ
Q1: How long does it usually take to see results from this treatment?
A: Generally, you’ll start to notice initial lifting effects around 4 weeks after the treatment, with results becoming more noticeable after 2–3 months, as it takes time for new Collagen to form.
Q2: Why do some people say the lifted look looks stiff and fake?
A: Generally, it’s related to the lack of adjustment for energy level and depth based on individual conditions. Using a high energy level uniformly across the entire face tends to cause unnatural tension, so it’s recommended to choose a doctor with experience in zone-specific adjustments.
Q3: Is it very painful during the injection?
A: It varies from person to person. There’s a more noticeable warmth sensation when treating the fascial layer, but the therapist will adjust the energy level on the spot based on individual pain tolerance, so it’s generally tolerable.
Q4: How soon after the procedure can I wear makeup and return to work?
A: In most cases, you can apply makeup and go to work normally on the day of the procedure, with no noticeable recovery period. However, it’s recommended to enhance moisturization and sun protection.
Q5: Who is not a good candidate for the American version of the second-generation ultrasound?
A: People who are pregnant or breastfeeding, have severe skin inflammation, or have metal medical implants are advised to consult a doctor for an evaluation first.
