As we age, facial fat will gradually sag and droop, resulting in pockets at the corners of the mouth, an increasingly indistinct jawline, and a double chin at the same time. Regarding how to solve such problems, the most common is the facial plus and minus method. The minus method is to remove the sagging and displaced fat, and the traditional way is liposuction, where a hole is made in the hidden part of the face, and then the excess fat is suctioned out by means of negative pressure. The advantage of this method is that it is simple and does not require any special instruments. The disadvantage is that it can do nothing about the problem of skin laxity and requires very high personal skills, otherwise the problem of unevenness may occur. Later, with the advancement of science and technology, the way of fiber optic lipolysis appeared. Fiber optic lipolysis is a fiber optic beam, the laser head in the front of the beam, through the carbonization after the subcutaneous melting of excess fat, and at the same time the skin tightening effect. The advantage is that liposuction, tightening in one, the effect is maintained for a long time, but also popular for a long time. Of course, fiber optic lipolysis for the technical requirements are also very high, if the probe is too shallow, it will be easy to burn through the skin, skin necrosis, if it is too deep there may be nerve damage. At present, the Israeli company has upgraded on the basis of gold micro-sculpting and launched a product called diamond fine sculpture. It is through the radio frequency head in the subcutaneous heating, while temperature control and monitoring, bilateral electrodes bilateral temperature control, and reached a fully automatic state, to ensure that in the case of thermal fusion lipolysis, but also accurate and does not damage the human body’s tissues, the surgical safety has been greatly enhanced, but also I personally very much recommend a way.
