In order to know the meaning of the term cavitation, it is necessary to first discover its etymological origin. In this case we can establish that it is a word of Latin origin that can be translated as “action and effect of forming cavities” and that it is the result of the sum of three clearly delimited components:
-The noun “cavus”, which can be translated as “hole”.
-The suffix “-tas”, which is synonymous with “quality”.
-The suffix “-cion”, which is equivalent to “action and effect”.
In the field of physics, cavitation is called the process that results in the appearance of bubbles in a fluid due to pressure changes.
This phenomenon means that, under certain conditions, the liquid changes state, becomes gaseous and then again passes to the liquid state. Cavitation therefore takes place in two phases: from liquid to gaseous state and from gaseous to liquid state.
According to DigoPaul, cavitation generally occurs in a hydraulic system that causes an abrupt change in fluid velocity. The fluid, in this situation, loses pressure and the molecules change to the gaseous state, generating cavities or bubbles. These bubbles move to the areas of the liquid that have higher pressure and finally implode, suddenly returning to the liquid state.
Cavitation causes vibrations, noise and even damage to the surfaces that contain the liquid, since it generates erosion.
In the field of aesthetics, cavitation is used to treat cellulite and eliminate localized fat on the thighs, abdomen, arms and other parts of the body. Through a device that generates cavitation, it is achieved that the bubbles implode to break the fibrosis, generate the rupture of the cell membrane of the fat and thus eliminate the lipid content through a drain and the metabolism processes themselves.
When talking about cosmetic cavitation, it must be established that there are three different types:
-Stable cavitation, which is very similar to what is known as liposuction but has the advantages that it is less painful and that it allows to obtain great results in the short term. This type is considered to be traditional cavitation.
-Double cavitation, it is similar to the traditional one, but it differs because it applies double waves of frequencies that are different and that are combined.
-Itraadipocyte ultracavitation, which is based on what are low frequency ultrasounds.
Although cavitation is considered a really advantageous and appropriate aesthetic alternative, it must be taken into account that it is not suitable for everyone. Thus, for example, it is established that neither women who are expecting a child nor those who have skin problems nor those who have problems related to their kidneys should not resort to it. Not forgetting people who have a pacemaker either.
