One of the most widespread diseases nowadays is obesity in many countries. It carries a significant cardiovascular and overall mortality rate, directly or indirectly associated with multiple cardiovascular risk factors. Several studies have demonstrated this relationship between obesity and cardiovascular disease, and it has been estimated that 20-30% of overall cardiovascular mortality is attributable to excess body weight. For all these reasons, obesity is a significant cause for concern from a social and health point of view. 


Obesity is a worldwide epidemic that has been increasing in recent decades due to various factors (sedentary lifestyles, convenience foods, etc.), and its diagnosis and treatment are widely described in the literature. In contrast to the vast bibliography found on obesity, there are few publications on localized adiposity in indexed medical journals, as well as few studies with a scientific basis and rigor of the most current treatments derived from it, reflecting the need for studies in this area. 


What is cavitation?  


When we talk about cavitation, it is a process where it disappears millions of tiny bubbles in the liquid. These bubbles occur throughout the liquid mass, reaching small fissures or crevices. 


Cavitation occurs naturally with the evaporation of a liquid when the energy is not sufficient to hold the molecules together. The molecules then separate from each other, and vapor bubbles appear. 


To reproduce this phenomenon, cavitation is produced by the alternation of compression and depression generated during a half-cycle of the sound wave. This gives the formation of high and low-pressure points. As the liquid is dilated beyond its tensile strength during the depression, these cavities begin to increase their original size. 


Aesthetic medicine 


An example of the use of cavitation is in the field of aesthetic medicine. In aesthetic centers, cavitation is used to eliminate localized fat. It is a less invasive method than surgery to remove localized fat. Low-frequency ultrasound is applied to the affected area where fat accumulates trapped in the skin's connective tissue. 


Cavitation dissolves the fat cells and converts them into liquid. The body then eliminates this water through the lymphatic system. 




  • Convenient: The treatment is entirely painless. It is performed in consultation. It does not require anesthesia or girdles. 


  • Safe: Only a predetermined amount of ultrasonic energy is precisely directed to the desired area within the adipose panniculus. The surrounding tissue remains intact and unexposed. 


  • Selective: Only adipocyte membranes are ruptured. No epidermal injury occurs. 


Frequency modulated waves 


Both ultrasound and cavitation are acoustic wave emissions; the difference is that in the case of ultrasound, the emission frequency is high, while in cavitation, it is low. The term ultrasound could be used to refer to any of these technologies, especially if we consider that cavitation is not a technology in itself but the phenomenon that occurs due to the propagation of these low-frequency sound waves.  


The basis of action in ultrasound and cavitation is the same: the conduction of the waves to the fatty tissue destroys fat cells and thus the disappearance of adipose accumulations in localized areas. The variations in emission frequency have allowed certain specifications, such as ultrasonic thyroplasty or focused ultrasound HIFU, the latest of the latest, presented through a new generation of equipment, doubling efficiency and precision. 


Triple ultrasonic action 


The effectiveness of cavitation and ultrasound responds to a triple mechanism of action-reaction: 


Mechanical, The emission of sound in the form of waves generates pressures and decompressions that produce an oscillatory movement in the subcutaneous tissue. This back and forth movement translates into a micro-massage that increases the permeability of the cell membranes to the point that micro-cracks are produced through which the fat content migrates. This mechanical effect, in turn, favors the mobility of waste liquids stagnant in the tissue, which results in cellular, tissue, and circulatory stimulation, with the consequent toning of the skin tissue and the reduction of fat accumulations and cellulite.  

On the other hand, this mechanical effect of vibratory massage explains why ultrasound can enhance the transport of active cosmetic ingredients to the deepest layers of the skin through sonophoresis, one of the variants of virtual mesotherapy. 


Thermal The oscillatory movement derived from the mechanical effect causes continuous friction between the molecular particles, triggering a temperature rise. It also has essential analgesic, anti-inflammatory, and antispasmodic effects, which is why ultrasound is also used in many analgesia and rehabilitation therapies.  


Chemical-Metabolic The mechanical massage is also responsible for a chemical reaction, which causes the cellulite to soften because its gelatinous texture becomes more liquid, significantly facilitating its elimination.  


Application of cavitation 


The effects can be used in liquids for many processes, e.g., mixing and blending, deagglomeration, pulverizing, and cell rupture. In particular, the high shear stress of the liquid jets causes cracking on particle surfaces and collisions between particles.
