The difference between thermage and hifu machine, Which one to choose?

Working principle:

HIFU: High-intensity focused ultrasound (HIFU) heat penetrates the skin (60-75 ° C), causing damage to the subcutaneous tissue, thereby stimulating collagen contraction and proliferation, resulting in the effect of pulling the face.

Thermage: Use radio frequency (RF) to heat the skin from the outside to the inside: (40-55 ° C), let the subcutaneous tissue denatured and shrink, so that collagen proliferate to achieve firming effect.

It can be seen that the HIFU has a focusing characteristic (similar to the magnifying glass in the sunlight), which is suitable for precise treatment. The thermage is widely used, in addition to the face can also take care of the body. In addition, although both have anti-aging effects, the hifu is upwards and the person with less facial flesh is better. And Hot thermage focuses on tightening inward, and people with more fleshy face play better.

Treatment depth:

The skin is divided into epidermis, dermis, subcutaneous tissue, SMAS fascia, muscle, and finally bone.


HIFU: acting on the fascia layer (SMAS), the depth is about 1.6-4.5mm under the skin.


Thermage: It acts on the dermis and has a depth of about 2.6~3mm under the skin.


It can be seen that the lifting of the hifu machine is relatively more thorough.



Safety is mainly at the temperature, instrument and doctor qualification.

Temperature: The subcutaneous tissue is mainly composed of proteins, which begin to contract at around 45 to 50 °C. Among them, the temperature of the hot maggie is 40-55C, which is relatively safe. The ultrasonic knife has a temperature of 60 to 75 C, which is the strongest temperature the skin can withstand. It is true that the higher the temperature, the stronger the effect, but the tolerance of high temperature to the skin is a great test. If the subcutaneous collagen and hyaluronic acid content is low during operation, the high temperature will cause the skin to directly necrotize and "melt" with the fascia layer. The consequences are not good, but the pigmentation is heavy - facial burns - skin collapse - expression is stiff. In order to reduce the risk, the regular hospital will give a large amount of oral special cell source nutrient solution before and after surgery, and try to protect the skin from harm.

In summaryChoose professional machines and qualified doctors.
