The present invention relates to an injectable composition for local fat reduction free from pain, edema and side effects, and a method for producing the same, more specifically, glycocholic acid (or a salt thereof) or taurocholic acid (or a salt thereof), and phosphatidylcholine ( PPC) in a specific blending ratio, including pain, edema, and necrosis of muscle cells, fibroblasts and vascular endothelial cells in addition to adipocytes, anesthesia at the administration site, extensive swelling, erythema, hardening, and sensation. The present invention relates to an injectable composition for local fat reduction, which is free from side effects such as abnormalities, nodules, pruritus, burning sensation, nerve damage and dysphagia, and a method for producing the composition. A conventional DCA single injection known as a local fat reduction injection, or a PPC injection composition containing a solubilizing agent DCA is used in addition to adipocytes, fibroblasts, vascular endothelial cells and skeletal muscle cells. Necrosis, which is caused by lysis and inevitably, causes pain and side effects such as anesthesia, extensive swelling, local edema, erythema, induration, paresthesia, nodules, pruritus, burning sensation, dysphagia, etc. In addition, while the patient complains of pain, discomfort, and anxiety, and the compliance with medication is low, the injection for topical fat reduction of the present invention has a safe and stable formulation, and lipolysis and An excellent composition that has an excellent effect of selectively inducing cell death (apoptosis) of adipocytes only in adipocytes, does not have the above-mentioned side effects, improves the quality of life of patients, and enhances adherence to medication.
