Face Lifting Before and After

HIFU beauty machine has revolutionized the field of non-invasive cosmetic and medical procedures. Within the realm of HIFU, different dimensional variants have emerged, each offering unique benefits and applications. This article contributed by Synogal aims to provide a comprehensive understanding of the disparities between 2D, 3D, 4D, and 7D HIFU machines, shedding light on their capabilities and potential implications in various treatment settings.


HIFU (High-Intensity Focused Ultrasound) Knife, originating from South Korea, is a non-invasive ultrasound technology that directly targets the SMAS layer. The high-intensity focused ultrasound technology of HIFU emerged in the 1940s as an ultrasound surgical technique. It utilizes ultrasound waves as a source of energy, leveraging their penetrative and focused properties to concentrate ultrasound energy in the SMAS layer of the human body. This creates a region of high acoustic intensity within the SMAS layer called the focal zone. The HIFU device can reach depths of 3.0mm to 4.5mm beneath the skin, raising the temperature of the SMAS tissue to 65℃ or higher within 0.5 to 1 second, resulting in collagen remodeling within the SMAS tissue without damaging the surrounding normal tissues. This leads to the effect of fascia lifting.

What is Ultrasonic (US) Technology?

Ultrasonic technology refers to sound waves with a frequency higher than 20,000 Hz, which is beyond the range of human hearing. It can vibrate at a rate of 20,000 to 1 billion times per second and is typically generated by mechanical vibrations.

What is the SMAS Layer?

The SMAS layer (Superficial Musculoaponeurotic System), also known as the fascial layer, is the surgical plane targeted by facelift procedures performed by plastic surgeons. The SMAS layer is located approximately 4.5mm deep within the skin, between the subcutaneous fat and the muscles.

2d hifu machines

The 2D HIFU machine operates similarly to Ultherapy, providing an efficient and safe method for skin rejuvenation. With the most widely accepted cartridge depth options of 1.5/3.0/4.5mm, it effectively targets areas such as the forehead and cheeks. A single button press produces a single line for precise treatment. This innovative technology has gained FDA approval for lifting the skin on the neck, eyebrow, and under the chin, while effectively reducing lines and wrinkles. Its capabilities make 2D HIFU a trusted and professional solution for rejuvenating the skin, offering transformative results and instilling a renewed sense of confidence in patients.

The 3D HIFU machine is specifically designed to effectively eliminate fat cells within the adipose tissue near the targeted area. With its remarkable capabilities, it supports up to 11 lines per single button press, enabling beauticians to save valuable time and effort when providing localized treatments. This advanced technology offers 521 shots per press, providing a broader range of options for treatment depths. Additionally, the machine offers 6mm, 8mm, and 10mm cartridges, accommodating various fat thicknesses at different depths. The versatility and precision of the 3D HIFU machine make it an invaluable tool in body contouring and localized fat reduction treatments, ensuring optimal results for both practitioners and customers.

The manufacturer of HIFU machines presents the 4D HIFU Machine, a revolutionary device for vaginal rejuvenation that has been available since 2017. This advanced machine incorporates several unique features, including a handle similar to 3D HIFUs, an additional v-max handle, and a specialized handle specifically designed for precise treatment of the female vaginal area. Unlike its predecessors, the 4D HIFU machine can effectively target even the smaller areas that were previously challenging to address accurately. The v-max head, with its circular design, has a diameter ranging from 3 to 5cm.

The standout feature of the 4D HIFU machine lies in its capability to achieve vaginal tightening without the need for surgery, making it a preferred alternative for many individuals. This non-invasive treatment typically requires only 1-2 sessions to achieve desired results. By applying the 4D HIFU in the vaginal layer, immediate effects can be experienced for up to 3 months, eliminating the need for additional procedures during that time. While the results may not be permanent, the convenience and efficacy of the 4D HIFU machine provide a viable solution for individuals seeking vaginal rejuvenation.

5D HIFU Machine

The 5D HIFU Machine represents a cutting-edge advancement in beauty treatments, as it combines various technologies to deliver remarkable results in wrinkle reduction, skin tightening, and improved cell turnover. This next-generation device utilizes RF frequency energy waves to enhance collagen production, leading to a fairer and more radiant complexion. The versatility of the HIFU machine allows for its application on multiple areas of the body, including the underarms, face, neck, collarbone area, and chest. For further information and comprehensive details, it is recommended to contact a reputable HIFU machine supplier who can provide in-depth insights into the capabilities and benefits of the 5D HIFU Machine.

The 7D HIFU machine represents a groundbreaking advancement in anti-aging treatments, offering the promise of long-lasting youthfulness. This device stands out from other skin tightening equipment on the market by providing a tailored treatment approach for the entire face, neck, and body. Using innovative sound wave technology, the 7D HIFU treatment efficiently tightens sagging skin and stimulates collagen production in significantly less time.

One key distinction between 7D HIFU and traditional HIFU lies in the technology employed. 7D HIFU utilizes the latest MMFU (Microfocus and Macro focus Ultrasonic) technology, an upgraded version of High Intensity Focused Ultrasound. This cutting-edge technology enables greater precision and effectiveness when targeting specific areas. Moreover, 7D HIFU offers different focal areas for both the body and face, while traditional HIFU is primarily effective on the face alone. Additionally, 7D HIFU can impact various layers of the skin, whereas traditional HIFU is limited to depths of 5/3.0/1.5mm. Notably, the 7D HIFU treatment is virtually painless, distinguishing it from traditional HIFU treatments that may cause some discomfort.

With its advanced features and superior technology, the 7D HIFU machine revolutionizes the field of non-invasive anti-aging treatments, providing individuals with the opportunity to achieve remarkable results and a rejuvenated appearance.
