In this era that pursues refined beauty, people still struggle against aging; smooth faces, firm skin, and radiant complexions are what everyone desires. This is why many beauty salons and clinics have introduced HIFU devices to attract more customers. However, the problem arises: with so many HIFU device brands on the market, each with different functions, finding the best HIFU device can be incredibly difficult. Are you feeling overwhelmed? Do you not know which is the best HIFU machine-4D, 7D, or 9D?

 

 

 

What do 4D, 7D, and 9D stand for in HIFU devices?

 

Beginners may be confused by terms like 4D, 7D, and 9D when choosing a HIFU device, with some believing that higher numbers indicate better equipment and stronger treatment effects. However, there is no direct, decisive relationship between these numbers. These numbers refer to the number of different depths the HIFU device can penetrate, and do not necessarily have a significant impact on the treatment effect.

 

 

 

What can HIFU treat for you?

 

HIFU is a high-intensity focused ultrasound technology that precisely focuses energy into the deep layers of the skin. Through a thermal effect, it stimulates collagen regeneration, lifting and firming the skin of the face, neck, and shoulders non-invasively, improving skin laxity and signs of aging. It can also improve sagging jawline and double chin, lift droopy eyelids and eyebrows, reduce fine lines and wrinkles, and help tighten and sculpt the contours of various parts of the body, achieving comprehensive facial and body care.

 

Furthermore, HIFU devices can improve your skin texture and tone, leaving your skin radiant. The entire treatment requires no surgery or anesthesia, and there is no recovery period afterward, allowing clients to quickly return to their daily lives and work. This is why HIFU devices consistently rank among the most popular beauty devices on the market.

 

 

 

What is the 4D HIFU Machine?

 

4D HIFU is the newer generation of Ultrasound. The extraordinary effects of high-energy ultrasound waves (HIFU) for skin tightening and skin rejuvenation have been proven. New advanced high-energy ultrasound techniques have been used to design 4D HIFU devices.

 

The four-dimensional HIFU device transmits deep ultrasound energy deep into the skin to do that. 4D HIFU waves pass through the epidermal layer and do not cause any damage to the upper layer of the skin, and depending on the cartridge used, they can penetrate to the desired depth.

 

4D HIFU exerts a thermal effect on skin collagen fibers, stimulating the superficial muscular aponeurotic system and literally breaking down fatty tissue. The skin is lifted and tightened. Preliminary results of 4D HIFU are visible at once after it is done, which will satisfy the clients very much. But the main results will be visible 4-5 months after HIFU therapy is done.

What is the 7D HIFU Machine?

Ultrasound energy is concentrated in the 7D HIFU device and is then targeted at a small focal point in the skin. New advanced micro&macro focused ultrasound techniques have been used to design 7D HIFU machines. This increases collagen and elastin production and the degradation of fats.

 

Collagen and elastin are the main factors in the youthfulness of the skin. These waves do not cause any damage to the skin or the surrounding tissue but rejuvenate the tissue in question. As a result, 7D HIFU devices can target deep layers of skin to tighten and rejuvenate the face without needles or surgery.

 

 

What is 9D HIFU Machine?

 

9D HIFU machine with 12 press line ultrasonic body slimming & face lifting, more than 21,000 shots according to quality inspection and clinical tests, ensuring that each shot effects into the right depth set by default. And max 12 lines of shots in one time save your treatment time. High-intensity focused ultrasound (HIFU) uses precise medical-grade ultrasound energy for non-surgical face lifting and skin tightening.

 

The 9D HIFU is a ninth-generation HIFU machine offering higher power, lesser discomfort, increased safety, and clinically proven results. New advanced MMFU techniques, High-intensity focused ultrasound techniques, Liposonix techniques, and Hi360 techniques have been used to design 9D HIFU machines.

It literally achieves the results of a facelift or a body lift without any invasive surgery or injections, moreover, an added bonus of this procedure is that there is no downtime. This technique can be applied to the face as well as the whole body, and also, it works equally well for people of all skin colors, in contrast to that lasers and intense pulse lights.

 

 

 

How to Choose the Right HIFU Device?

 

Define Your Core Needs

  • 4D HIFU: If your needs are relatively basic, mainly focusing on facial lifting and firming, a 4D HIFU device is a cost-effective choice.
  • 7D HIFU: If your services are more comprehensive, addressing more specific issues like stretch marks and fine lines, or if you highly value body sculpting (such as fat reduction and improvement of cellulite), a 7D HIFU device is better suited to your needs.
  • 9D HIFU: If your positioning is to provide high-end, personalized customized services, catering to diverse anti-aging needs and desiring longer-lasting effects, then the comprehensive capabilities claimed by 9D are worth your attention.

 

Focus on the Core: Treatment Head Configuration

Don't just look at the "D" number; carefully check which depths and specifications of treatment heads the device comes with, and whether the functions of these treatment heads are exactly what you need.

 

Consider Budget and Return on Investment

Generally, the higher the dimension and the newer the technology, the higher the purchase cost. You need to assess whether the potential benefits (such as more services available, higher fees, and greater customer appeal) justify the investment.

 

Verify Equipment Qualifications and After-Sales Service

Regardless of the type chosen, you must confirm that the equipment complies with local medical device regulatory standards (such as CE, FDA certification, etc.). Simultaneously, understand whether the supplier provides comprehensive operational training, technical support, and warranty services; this is crucial for the long-term stable use of the equipment.

 

 

 

What benefits can purchasing a HIFU device bring to your business?

 

  • Expand your service scope and customer base

HIFU devices not only effectively improve issues like sagging jawlines, facial wrinkles, and double chins, but also help with facial lifting and body sculpting, giving you a perfect figure. Furthermore, HIFU technology is also effective in vaginal tightening. This advanced, multi-functional device allows you to serve a wider customer base, expanding your business from basic care to more specialized skin treatments.

 

  • Build long-term, stable customer relationships

Due to the versatility of HIFU devices, customers can choose maintenance treatments or additional treatments on other facial and body areas. Moreover, HIFU treatment is not a one-time event; it's a long-term process, allowing you to build long-term, stable relationships with customers and provide a consistent source of income for your beauty center.

 

  • Provide ideal treatment plans and increase customer repeat purchase rates

HIFU treatment is a non-invasive facial care therapy. The treatment process requires no surgery or recovery period, is short in duration, and yields significant results. This is precisely the ideal treatment solution needed by people accustomed to today's fast-paced lifestyle. Furthermore, HIFU treatment is the absolute first choice for those seeking fast, safe, and effective treatments. These advantages provide customers with an excellent treatment experience, thereby increasing customer satisfaction and repeat purchase rates.

 

  • Enhancing Professional Image and Brand Value

A good device not only provides satisfactory treatment but also enhances the reputation of a beauty institution and its word-of-mouth among customers-a crucial aspect that cannot be ignored in any business. As a representative of high-tech beauty equipment, HIFU devices can significantly enhance your institution's professional image, implicitly increasing customer trust. Without customer trust, even the best technology will struggle to sustain business.

 

 

 

 

SUMMARY

 

As a non-invasive treatment for professional facial and body beauty care, HIFU technology has long been the ideal choice for professional beauty salons, clinics, and other beauty institutions. If you want to expand your business and attract more customers through HIFU equipment, you must choose it based on your business needs and budget.

 

The big difference between the HIFU machines is the technique, result, customer experience, and cartridge number. In general, if your budget is not enough, you can choose a 4D HIFU machine. If you have a certain budget and want to purchase a machine with better performance, then you'd better choose a 7D HIFU machine. If you don't need to consider the budget and want to give customers the best experience and attract repeat customers, 9D HIFU is undoubtedly the best choice. Since the 9D HIFU machine applies more technologies than the previous two machines, the larger handle will save time for customers, make customers feel almost no discomfort, and the effect will last longer.

 

There is no best machine, only the most suitable instrument. At the same time, a beauty equipment manufacturer with qualified product certifications and a comprehensive after-sales service system is also crucial, as this will save you a lot of unnecessary trouble.
