Cryolipolysis is a non-invasive procedure that aims to reduce localized fat, that is, one that is concentrated in certain areas of the body and which is very difficult to get rid of even with an adequate diet and exercise, as the famous "Little tire".The word "cryolipolysis" is the combination of three scientific and ancient words. "Krios", which comes from the Greek and means "cold", "lipo", which means fat "and" lise ", which means" breaks ". That is, Cryolipolysis is the breakdown of fat through the cold.The technique involves placing a machine that works with the use of a tip similar to a vacuum cleaner, which sucks up the superficial fat through the creation of a vacuum and submits it to low temperatures.The low temperature affects fat cells, causing their death and subsequent absorption and elimination. It is not yet known exactly what the fat elimination mechanism is, but there are 3 hypotheses: it is either eliminated by the lymphatic system, or by the liver, or it is reused by the body to produce sex hormones.Each session lasts about an hour and, because it is not invasive, allows the patient to return to normal activities on the same day. The sessions must have an interval of at least 2 months between them, being able to be held safely in up to 4 regions at the same time.It can be done in the body contour, abdomen, back, flanks, thighs, buttocks, arms and knees and has been shown to be an effective procedure in fulfilling its purpose. However, obtaining good results also depends on the patient's behavioral factors.
