The difference between fine needle and fat-dissolving needle lies in the different principle. The principle of visfatin is to block the nutrition of muscles and make them contract slowly, thus removing body fat. Fat-dissolving needle can directly dissolve the body fat and excrete it through metabolism in the later stage, both of which can achieve the effect of losing weight in a short time. If you want to lose weight quickly, you can't choose to take some diet pills or use some diet products. No matter what injection method is used, it is recommended to go to a professional beauty institution or medical institution for professional treatment.
