4D vs. 7D HIFU? Which One Is Better?
The main difference between 4D HIFU and 7D HIFU devices is the speed of operation and the number of cartridges. 7D HIFU has the largest number of cartridges, i.e., 7 in seven different depths, which can be well used for slimming certain areas of the body and rejuvenating and lifting all parts of the face and neck, even around the eyes and mouth.
7D HIFU devices have two modes of single shot and continuous operation. You can put the device on continuous mode, and with one press of the button, you can see the shots are repeated until you press the button for the second time. There will only be one shot in single-shot mode each time you press the cartridge button.
The results of 7D HIFU therapy last one to two years, but the amount of collagen production in the skin will be higher than before. When performing HIFU therapy with older devices, the patient feels a little sore, but with 7D HIFU therapy, all will be almost painless and quick.
| 7D HIFU | Faster speed of operation | 7 cartridges | Newest technology | More Popular | Smaller focus point (more accurate) | Working in 7 layers of skin |
| 4D HIFU | Slower speed of operation | 4 cartridges | Older technology | Less Popular | Bigger focus point | Working in 4 layers of skin |
Why is 7d HIFU better than 4d used in every other clinic ?
7D HIFU is the latest technology in HIFU therapy introduced in 2022 and is now more popular than the ageing 4D HIFU therapy. But there are also other considerations that will inevitably lead every client to choosing 7D HIFU over older technologies.
- 7D HIFU has a smaller focus point than other HIFU devices. As a result, high-energy concentrated ultrasound transfers energy more accurately to the target skin tissue layer, resulting in a thermal coagulation effect without damaging the surrounding tissues. This focused energy, while stimulating the proliferation of collagen and elastin fibers, dramatically improves comfort and gives you a great look with healthy, firm, and elastic skin.
- A 7D HIFU device has seven different cartridges that allow you to perform in 7 different layers of skin. Cartridges of 1.5, 2, 3, 4.5, 6 and 13 mm. Cartridges from 6 onwards enter fat tissue under the skin and change the use of HIFU therapy from rejuvenation to slimming and cellulite reduction.
- A 7D HIFU device comes with two different handpieces. There is a handpiece for the face used for rejuvenation and another handpiece for the body for slimming and lifting purposes.
- 7D HIFU is better than older HIFU devices in terms of results and has extraordinary power. The effects of HIFU therapy in this case last one to two years, and the amount of collagen production in the skin will be higher.
- Add to that the fact that the client usually feels a little discomfort when performing HIFU therapy with older devices, but 7D HIFU technology is much less painful and also much faster in comparison.
