In recent years, more and more people are showing great interest in microplastic surgery. For example, a shot of Botox can get rid of age-revealing wrinkles; a shot of hyaluronic acid can create a beautiful face shape. Many people want to be able to dissolve excess body fat through non-invasive injections. Therefore, “lipolysis injection” has come into people’s view. The principle of lipolysis is that it contains ingredients that accelerate the breakdown and metabolism of fat, such as phosphatidylcholine. The main way it works is by changing fat metabolism and accelerating fat decomposition. It does work well for small localized areas of fat accumulation. However, this method takes a long time to work, and in addition to the need for multiple injections, poor technique or poor selection of indications can make the skin more prone to unevenness. In addition, if the dissolved fat cannot be removed by the body in time, there may also be a risk of fat liquefaction and infection, so it cannot be applied locally in large quantities. So far, although it has been widely used in Europe and the United States, domestic private hospitals and clinics and other medical institutions are carrying out such projects, and have achieved relatively good results. However, China’s Food and Drug Administration has not yet approved its official application. We also hope that after a lot of experiments and preliminary clinical practice to verify its effectiveness and safety, it will be widely used in the clinic as soon as possible for the benefit of the majority of beauty seekers.
