Injection of fat-dissolving needle is to inject liquid containing slimming ingredients directly into the subcutaneous fat layer of human body in the form of needle to dissolve subcutaneous fat. When the drug passes through subcutaneous tissue, it stimulates the increase of lipase in local adipose cells, and then stimulates the activation of protein, so that the intracellular deoxynucleotide triphosphate is converted into deoxynucleotide, which promotes the activation of fat, increases the cut-off fatty acid, decomposes it into fine state, and excretes it into lymphatic system randomly.
