At present, it is about local fat reducing ingredients without pain, edema or side effects and a preparation method. More specifically, it is currently associated with an ingredient, including glycerin (or a salt thereof) or polyphosphate (or a salt thereof) and phosphoric acid (PBC), which reduces local fat in a specific mixture without side effects such as pain, edema, muscle cell necrosis, etc, Intravascular non additive fibrosis and cells, management site anesthesia, large swelling, hedgehog, sclerosis, equality, cathode,There's a burning sensation, nerve damage and disorder, and there's a way to prepare. It is known that the simple alkaline catalytic decomposition or PPC injection, i.e. the traditional injectable weight loss agent, combines the alkaline catalytic decomposition as a dissolving agent with this side effect, such as pain, anesthetic, large swelling and local edema, Hedgehog, sclerosis, equality, cathode, Prut, burning sensation, dysfunction, etc. due to cell necrosis, it is inevitable that not only fat but also fibrotic lameness will result,Vascular endocrine cells and skeletal muscle cells As a result, patients have been complaining about pain, discomfort and anxiety without adequate treatment. On the other hand, the injection composition currently used to reduce local fat is a safe and stable formula, which selectively carries out fatty lysine and has a strong effect on the Apocalypse induction of adipogito, Therefore, it is a good component that can improve patient compliance and quality of life without the side effects mentioned above.La presente se relaciona con una composición para reducir grasa localizada sin dolor, edema ni efectos secundarios, y con un método para preparar la misma. Más específicamente, la presente se relaciona con una composición que comprende ácido glicocólico (o una sal del mismo) o ácido taurocólico (o una sal del mismo) y fosfatidilcolina (PPC) en una proporción de mezcla particular para reducir grasa localizada sin e
