Cavitation is the name of a physical process used in many technical fields, and recently actively used in medicine and cosmetology.

What it is?

It is known from the university physics course that cavitation (from the Latin cavitas, which means “emptiness” in translation) is the process of formation of cavities in a liquid (also called cavitation bubbles, or caverns) filled with gas, steam, or a mixture of them. There are two types of cavitation: hydrodynamic and acoustic. Hydrodynamic cavitation occurs when the pressure in a liquid decreases with an increase in its speed. Acoustic cavitation occurs in a liquid when an acoustic wave of high intensity is passed through it. The cavitation bubble that arises in the process, moving with the fluid flow to an area with a higher pressure, can collapse, with the formation of a shock wave and the release of a large amount of energy.

In industry, the cavitation process is used in ultrasonic cleaning of surfaces and parts, for the destruction and dispersion of solids, the creation of fuel emulsions and mixtures, in water treatment devices and many other areas and areas. Recently, it has been used in medicine for the destruction of stones in the kidneys, gall bladder and bladder, treatment and cleaning of purulent wounds, disinfection of solutions, in the work of surgical instruments for bloodless excision of tissues of dense organs, as well as in dentistry and aesthetic medicine. In aesthetic medicine, the cavitation process is used to remove fat deposits and cure cellulite, while avoiding surgery.

The essence of the cavitation technique for the treatment of cellulite and the removal of fatty deposits is the effect of a low-frequency ultrasonic wave on adipose tissue. Since ultrasound is an acoustic wave, when it acts on fat cells (adipocytes), the effect of cavitation occurs in them. The formation of air bubbles in fat cells leads to an increase in their size and the displacement of fat molecules from them. In addition, the process of collapse of the bubbles inside the cells leads to damage to the cell membranes of adipocytes, and the membranes of the most fat-filled cells are damaged first of all, due to their greatest stress. The released fat molecules enter the intercellular space, from where they are quickly excreted through the lymphatic system and the circulatory system. Note that the effect of cavitation on other cells and tissues (muscles, skin, blood vessels, etc.) does not lead to their damage, since they are stronger and more elastic than adipose tissue. Note that this conclusion is confirmed by a large number of scientific studies and experiments devoted to the study of the safety and efficiency of the cavitation process.

How is the cavitation procedure performed?

Immediately before the procedure, a lipolytic gel is applied to the skin, which reduces the friction that occurs between the working head and the skin. In addition, penetrating into the subcutaneous layers of the epidermis, lipolytic gel accelerates the breakdown of fat cells. Then the cosmetologist, depending on the area of ​​the treated area and the degree of obesity, selects the necessary program and passes over the surface with a working handpiece.

The average duration of one session is 20-30 minutes, and the maximum duration of the procedure is limited to 60 minutes without the risk of overheating. Sessions are held no more than once every 10 days, and the average course consists of 3-4 sessions. If necessary, after some time, but not earlier than six months later, another course is conducted, consisting of 1-3 sessions.

The effect of cavitation is noticeable after the first session and intensifies over the next few days. First of all, patients note a decrease in volume, and weight changes, as a rule, are not so noticeable. This is due to the fact that adipose tissue has a low density, which means that, despite the large volumes, it is quite light. The practice of this procedure has shown that in one session the body can lose up to 15 cubic meters. see fat, which corresponds to a decrease in the waist by 3-5 cm.

To enhance the effect and achieve the best result, it is necessary to maintain an active lifestyle and adhere to proper nutrition and drinking regimen, especially in the days before, during and after the procedure.


Advantages procedures

To date, the cavitation procedure is actually the only non-surgical method that directly affects adipose tissue. Cavitation is considered the most effective and safe way to lose weight, and the procedure itself is often called non-surgical liposuction.

Other benefits of cavitation include:

  • quick result
  • no injuries and no recovery period
  • longevity of the result
  • absence of aesthetic defects (failures of the skin, tuberosity, bruising and pain)

Contraindications to the appointment of the procedure

Cavitation is contraindicated in the following cases:

  • pregnancy
  • osteoporosis
  • diabetes
  • oncological diseases
  • some cardiovascular diseases (hypertension, phlebitis, vascular fragility, etc.)
  • skin diseases
  • kidney or liver failure
  • the presence of metal implants

We also note that the emission of ultrasound is not recommended to be done in the glands and genitals, as well as joints, eyes and ears.

Even if you do not have all of the above contraindications, we recommend that you consult with your doctor before performing the cavitation procedure.

Be healthy and beautiful!
