HIFU vs Ultherapy
These two may seem similar in terms of methodology since both use ultrasound treatment – a popular choice for nonsurgical facial tightening and lifting – but they still have some differences that every discerning customer must learn.
Extent of Skin Penetration
As the name implies, HIFU uses high-energy ultrasound and is primarily used for medical applications, such as non-surgically ablating tumors. It can also be used to vaporize adipose (fat) tissue for body contouring. In contrast, Ultherapy, uses a much lower ultrasound energy to treat the superficial layers of skin, although it is also able to penetrate a depth of up to 5mm of the second layer of the skin.
Mechanism of Action
The action that can be found in HIFU involves thermal as well as cavitation to cause cell disruption and cell death. The ultrasound energy cause molecular vibrations which result in heat generation and a rapid rise in temperature along the focal zone which will then stimulate collagen renewal. On a cellular level, the elevated temperatures also trigger a mechanical process that will result in cell death hence the elimination of fat cells. Meanwhile, Ultherapy relies only on heat to stimulate collagen contraction.
HIFU triggers two concurrent mechanisms to bring about skin tightening/lifting, while taking care of the stubborn fats to better define facial contours.
Extent of Pain
Those who have tried HIFU reported that it gave them tolerable pain, and it is much less than the one experienced with Ultherapy. If you compare it also to other popular treatments like Thermage, HIFU doesn’t cause any discomfort.
In terms of cost, HIFU is also known to be cheaper not only in comparison to other ultrasound devices, but other similar non-surgical skin tightening and lifting treatments.

As patients, it is always wise to keep in mind that no non-surgical procedure can have the same effect as a surgical facelift or a mini facelift. You must manage your expectations when you think about the change that is to be achieved.
