Second-generation American HIFU

The second-generation Ultherapy Prime (US version) is a non-invasive anti-aging device launched by US-based Merz in September 2024, officially entering the Chinese market in March 2025. As a revolutionary upgrade to the first generation, its core technology is based on the High-Intensity Focused Ultrasound (HIFU) principle, using Micro-Focused Ultrasound with Visualization (MFU-V) to precisely deliver energy to deep skin tissues.

The device's greatest technical breakthrough is its integration of the next-generation DEEPSEE imaging system, which improves ultrasound imaging resolution by 35% and extends the detection depth from 4.5mm in the first generation to 8mm. This allows physicians to clearly visualize skin structures from the epidermis down to the SMAS fascia layer, acting like a "high-definition magnifying glass" to precisely target treatment areas while avoiding damage to nerves and blood vessels.

During treatment, the device focuses ultrasound energy at three distinct subcutaneous depths: 1.5mm (superficial), 3.0mm (middle), and 4.5–8mm (deep), creating thermal coagulation points that stimulate collagen contraction and regeneration. This layered anti-aging mechanism simultaneously improves superficial fine lines, tightens the mid-layer dermis, and lifts the deep fascia, achieving a non-surgical facelift effect.

Compared to the first generation, the second generation features optimized energy control with an intelligent dynamic adjustment system that automatically matches energy output to skin thickness. This increases treatment speed by 20%, reducing full-face treatment time from 60 minutes to approximately 45 minutes. Additionally, by improving the energy release pattern, pain levels are reduced by about 30%, allowing most patients to tolerate the procedure without topical anesthesia.

Suitable Candidates

The second-generation Ultherapy Prime (US version) is primarily suitable for individuals aged 30–50 showing early signs of aging, particularly those with the following needs:

Moderate to mild skin laxity: It delivers significant improvements for issues such as blurred facial contours, undefined jawlines, and drooping apples of the cheeks. Clinical data indicates that collagen regeneration peaks 2–3 months post-treatment, with lifting effects gradually becoming visible; results are optimal at 6 months, with a single treatment lasting 1–2 years.

Marked nasolabial folds and neck wrinkles: Due to its ability to precisely target the SMAS fascia layer, the device offers unique advantages in improving nasolabial folds, marionette lines, and neck laxity. A Korean patient reported: "Three months after treatment, my nasolabial folds became significantly shallower, and the skin on my neck felt much tighter."

Those concerned about pain and seeking comfort: By optimizing energy output and incorporating a silent design, the second generation has greatly enhanced treatment comfort. Most users describe the sensation as "like light ant bites," with only mild stinging in sensitive areas such as the temples and brow bone.

Individuals with sensitive skin seeking anti-aging solutions: The device distributes energy more evenly and employs real-time temperature control technology, reducing irritation to the epidermis and allowing those with thin skin or a tendency to flush to undergo treatment safely.

It is important to note that the second-generation Ultherapy Prime (US version) is not suitable for everyone. Individuals with severe skin laxity, excessively thin skin, or minimal facial fat, as well as pregnant or breastfeeding women, are advised against treatment. Furthermore, patients should avoid sun exposure before treatment and prioritize moisturizing and sun protection afterward to ensure optimal results.

Overall, the second-generation Ultherapy Prime (US version) stands out as a new choice in the non-invasive anti-aging field, thanks to its precise layered treatment, comfortable experience, and significant anti-aging results, making it ideal for those seeking to improve facial laxity and reshape a youthful contour without surgery.
