Beauty and slimming seem to be a lifelong pursuit for beauty lovers. But whenever they hear of any new beauty technology, they jump at the chance to try it. In fact, the use of good photothermal energy can also help beauty seekers. It not only helps beauty seekers to shape a beautiful face, it also helps in getting a slimmer body! In order to better show the curves of the body, most of the previous candidates chose the traditional medical method of “liposuction”. Liposuction is a major surgery that requires general anesthesia, which is not only risky, but also difficult to avoid unevenness in the area after the surgery. After liposuction, many people wear clothes that are indeed bumpy and beautiful, but after taking off their clothes, they see that the local skin is no longer flat, so they have an additional worry. Nowadays, the popular “lipolysis” is safer and more convenient than “liposuction”. Lipolysis is a procedure that has few surgical risks and can prevent and alleviate the problem of uneven skin after surgery, which is another gospel to beauty seekers by using light and heat energy in the “right” place. “Lipolysis” is the ultimate expression of light and heat energy in the field of medical surgery, and the beauty seeker may wonder, “How can we make the excess fat disappear without surgery?” The effective energy of light and heat is enhanced to invade the subcutaneous tissue to “destroy” the fat cells, which is called “laser lipolysis”. The effective energy of light and heat can also penetrate the epidermis and dermis non-invasively to reach the subcutaneous fat layer, destroying the fat cells and metabolizing them. Focused sonolipolysis, for example, is a way to destroy subcutaneous fat without surgery, using light and heat energy, which not only avoids the complications of traditional liposuction surgery, but also allows the patient to add points to their body without enduring great pain and inconvenience.
