Many people are often asked how a HIFU treatment works, as it is increasingly popular in the aesthetic world to hear about the wonders of these treatments.
Ultrasounds are mechanical vibrations in an elastic medium that have a higher frequency than audible vibrations. The destruction of fatty tissue by ultrasound can be performed by Non-Focused Ultrasound (Ultra-cavitation) or High Intensity Focused Ultrasound (HIFU). In both cases rupture of the adipocyte membrane occurs, in the first by pressure waves and in the second by thermal-mechanical effect.
The focused ultrasounds have their operation so that all the shots produced by the transducer are coincident at a point where the treatment acquires its maximum efficiency. The HIFU system selectively converges energy in depth (in the same way that a magnifying glass acts with solar rays), preserving the most superficial layers of skin intact. That is why this technology is extremely safe; HIFU technology can be applied in any phototype without the risk of skin lesions, allowing its use at any time of the year.
These are systems that are assisted by a "computer tracking system" to control body areas that have already been treated and not treated and perform a homogeneous treatment of the area to be treated.
The Facial HIFU
Although the best HIFU in the market are equipment that allows facial and body treatments, in this case we will deepen facial treatments.
There are certain problems derived from age that until now have been difficult to solve without resorting to surgery. We speak for example of excess skin on the face and neck. Over the years, production decreases and collagen degradation increases. In addition, it undergoes structural changes that produce a decrease in skin thickness and loss of elasticity, that is, in a word, aging.
The HIFU system is a modern technology that is emerging as the most efficient aesthetic medical application for the tightening of the skin and the non-surgical treatment of flaccidity by focused ultrasound. The sound waves generate heat, contracting and lifting the skin tissue without altering its surface. It applies to the area to be treated a heat that heats the tissues to a temperature and a controlled time which triggers the "Neocolagenesis" or remodeling of the collagen. This remodeling causes an improvement of the properties of the skin as well as the synthesis of the new collagen.
