Cryolipolysis technology makes use of the characteristic of fat cells that are afraid of cold, and uses a special probe with vacuum negative pressure to attract the fat layer. By continuously cooling down the fat layer to below 4℃, the fat cells will age in advance and die one after another, while the blood vessels, nerves, and muscles have low sensitivity to low temperature and will not be affected, so as to achieve the purpose of eliminating the fat cells without damaging the surrounding tissues. Through cryolipolysis to thin shoulders, there may be the following risks: 1, aggravate the burden on the liver: cryolipolysis will lead to a large number of fat cells early natural demise, the body’s natural metabolism of a large number of necrotic fat cells on the liver is a serious burden, resulting in liver function damage, so people with liver problems are best not to try the weight loss method; 2, freezing the skin: improper control of the temperature of the cryolipolysis, and after that, it may occur different degrees of redness, bruising, soreness, numbness, etc. Damage to the nerves will generally disappear gradually, within 1-3 weeks. However, there are also people who should pay attention to the fact that when receiving cryolipolysis, the temperature of the instrument is turned on too low, which leads to the skin not recovering from frostbite for a long time, and even leaving unsightly scarring. Cryolipolysis is more suitable for people who have stubborn flab that is difficult to solve locally, so it is not suitable for people who are obese all over the body. After cryolipolysis, pay more attention to drinking water and increase activity, which will speed up the body metabolism. In addition, do not take a bath on the same day, can not eat spicy, greasy food in the near future, eat less and more meals.
