Because the fat-dissolving solution of giant salamander introduces the liquid containing slimming components into subcutaneous tissue of human body in the form of atomization, it stimulates the increase of lipase in local fat cells, and then stimulates the activation of protein, so that the deoxynucleotide triphosphate in cells is converted into deoxynucleotide, which promotes the activation of fat, increases the cut-off fatty acid, and decomposes it into fine liquid, which is excreted through sweat, urine, lymphatic system and metabolism, thus achieving the effect of slimming and losing weight. The principle is to expel fat through metabolism and lymphatic system after liquefaction, so as to achieve the effect of losing weight.
