Regardless of which Botox is used, the only difference between the two is the purity of the toxin. The higher the purity, the less antibody will be produced when injected into the human body, and the more it is injected, the less it will be injected and the longer it will be maintained. Suggestion: Choose a regular hospital to inject Botox. At present, there are only two legal brands of Botox in use in mainland China, the imported BOTOX and the domestic Hengli. What is the difference between them? 1, the ingredients are different The excipients of BOTOX and HENRY are both proteins, but they are not the same. The excipient of BOTOX: the use of human blood albumin and human homologous, of which human blood albumin is also called serum albumin, extracted from the blood of healthy people; HengLi’s excipient: the use of and human heterologous porcine gelatin, and heterologous proteins are more prone to immune reactions (allergies). 2, different molecular size BOTOX: molecular weight is 900KDa kilodaltons, the molecules are round and large. Hengli: molecular weight size is different, ranging from 600-1200KDa. 3. Different production process BOTOX: adopts the “vacuum drying method”, which is not easy to produce antibodies. Hengli: adopts the “freeze-drying method”, which is easy to produce toxoid, and toxoid produces antibody but not effect. 4, different clinical application time 5, different dispersion BOTOX: the dispersion area after injection is 0.5 square centimeters. Hengli: the dispersion area is 1 square centimeter. What is diffusivity? In layman’s terms, it is like a drop of water on the paper, the size of the water lines scattered. What is the effect of dispersion size? Taking face slimming injection as an example, the smaller the dispersion area, the smaller it is, the less it will affect the surrounding biting muscles, and will not cause facial expression stiffness, eye drooping and other sequelae. Therefore, relatively speaking, in terms of safety, the United States BOTOX is better. 6, the dose size BOTOX: 100 units/branch and 50 units/branch two kinds of packaging. HENRY: 100 units/branch. How to avoid using fake Botox? 1, go to regular institutions to play Botox. Do not go to private clinics or beauty salons without medical qualifications, because the drugs imported by regular hospitals have a strict process system and channel security to ensure the authenticity of the drugs used. 2, look at the price, the price should be fair, not greedy for cheap. If a botulinum toxin only 500 yuan, a hyaluronic acid as long as 1,000 yuan, you can be sure that this is not the offer of regular drugs. 3, from the appearance of the drugs can also be initially recognized authenticity.
