HIFU, as a wrinkle-lifting device, originally originated in tumor treatment, as the high temperatures (60-100°C) generated by focused ultrasound can kill cancer cells. Lower-energy HIFU (50-65°C) can stimulate subcutaneous collagen contraction and regeneration, marking the beginning of HIFU's anti-aging application.

Anatomical Location of the SMAS:

The SMAS lies deep in the subcutaneous fat, closely adhering to the muscular fascia. Its thickness ranges from approximately 2.5 to 4.5 mm (varies depending on location, e.g., thinner in the forehead and thicker in the jawline).

Function of the SMAS:

Serving as the "framework" of facial support, tightening the SMAS can achieve a full-thickness lift (more effective than simply stimulating collagen).

Limitations of Radiofrequency/Laser:

Direct access to the SMAS is difficult, while surgical facelifts are highly invasive. HIFU uses non-invasive focused ultrasound to precisely target the SMAS.

Theory

——

Ulthera Ultra Sonic Lift is a professional non-invasive skin firming, wrinkle removal, and shaping equipment.Ulthera Ultrasonic Sonic Lift uses high intensity focused ultrasound (HIFU) to focus ultrasound on a single point to generate high energy, which acts on the musculoaponeurotic system (SMAS; superficial musculo-aponeurotic system) , Make the smas layer shrink, make the collagen produce immediate contraction and stimulate the regeneration and reorganization of a large amount of collagen, build a new collagen fiber network, and enhance the elasticity of the skin from the bottom of the skin. Realize the three major functions of skin tightening, wrinkle removal and shaping. It is the latest generation of wrinkle and anti-aging skin beauty project. Ulthera Sonic Wave Lift is a non-invasive and safe treatment method, which can play a very good effect in skin tightening, wrinkle removal, and shaping.

Key Technical Points for Precision HIFU Treatment of the SMAS

1. Precise Matching of Depth and Frequency

Ideal Parameters:

Frequency: 3.0-4.5 MHz (high frequency ensures shallow focus and avoids energy spread).

Depth: 3.0-4.5 mm (adjustable based on the patient's SMAS thickness; for example, 4.0 mm is commonly used for Asian jawlines). Dynamic adjustment technology automatically calibrates depth with an accuracy of ≤0.1 mm using real-time ultrasound imaging feedback. Depth can also be manually adjusted using preset settings based on the practitioner's experience.

2. Energy Control and Temperature Monitoring
Effective Energy Range: Single-point energy 0.8-1.2 J (too low is ineffective, too high can damage nerves).

Temperature Threshold: The SMAS layer must be maintained at 60-70°C (collagen denaturation temperature) for 1-3 seconds. The device features a temperature control system that uses MRI or infrared feedback for real-time temperature measurement. Pulsed emission is also available to avoid continuous heating that could cause epidermal burns.

3. Treatment Head Design and Focusing Accuracy
Multi-Focal Coverage:

The treatment head incorporates multiple transducers (e.g., 128 elements), forming a 3D focusing grid (e.g., a 4.5mm x 4.5mm area). This allows for precise coverage of the entire SMAS layer.

Epidermal Protection: An integrated cooling system (cold gel or cold spray) ensures epidermal temperature remains below 45°C.

Application

——

1. Lift and tighten the cheek skin

2. Improve chin line and reduce puppet pattern

3. Improve skin quality, make skin delicate and lustrous

4. Remove neck lines and prevent neck aging

5. Improve skin elasticity and contour tightness

6. Tighten the skin tissue on the forehead and lift the eyebrow lines

7. Eliminate wrinkles around forehead, eyes and lips

Energy Transmission

——

DS-1.5mm used to transmit high-energy focused ultrasound to the epidermis tissue, the ultrasound to penetrate the skin to a depth of 1.5mm, is responsible for activating the skin epidermis in thinner tissue. such as eye zone.
 

DS-3.0mm for transmitting high frequency focused ultrasound energy into the dermis layer of the skin tissue, the ultrasound to penetrate the skin to a depth of 3.0mm, is responsible for activating the skin's dermal layer of collagen effectively enhance the effect of the consolidation of the outline, but also improve large pores and reduce the appearance of wrinkles. targeted to chin, chest.
 

DS-4.5mm used to transmit high- energy focused ultrasound to the skin, subcutaneous tissue, the ultrasound to penetrate the skin to a depth of 4. 5mm, direct subcutaneous SMAS layer, targeted to thicker skin, such as cheeks, neck etc.

DS-8.0/13.0mm high intensity focused ultrasound activating in depth of 13mm/8.0mm, targeted to thicker skn, such as thighs, buttocks.
