Place of production
Hengli Botulinum Toxin is produced in Lanzhou, China, and Botox is produced in the United States.
safe
1, the composition is not exactly the same.
Botulinum: It consists of botulinum toxin A and human albumin. Human albumin, extracted from the blood of healthy people, has a certain detumescence effect, just like protein.
Hengli: It consists of botulinum toxin A and medical gelatin. Medical gelatin is a hydrolysis product formed by slight fracture of collagen fibers of pigs or cattle, which is easy to cause immune reaction, that is, allergic phenomenon.
2. Compared with the concentration, the concentration of thiopental sodium is slightly higher.
Botox: The molecular weight is about 900KD (kilodalton).
Equilibrium: the molecular weight is about 1300KD (kilodalton).
At the unit dose, the concentration of botulinum toxin is slightly higher.
3. Compared with permeability, dispersibility is not suitable.
Propofol: the dispersion area is 0.5 square centimeters.
Balance: the dispersion area is 1 cm2.
Because the concentration of botulinum toxin type A is slightly higher than that of Hengli, under the same size of injection needle, Botox will form higher injection resistance and pressure after injection. The smaller the permeability, the higher the concentration and the greater the injection pressure, which will directly lead to the smaller the dispersion area. The smaller the permeability, the more suitable for facial fine muscle injection.
4, process comparison, not exactly the same.
Botox: Vacuum drying is not easy to produce antibodies.
Balance: adopting freeze-drying method, it is easy to produce toxoid, but toxoid produces antibody without effect.
5. Long clinical application time.
Propofol: It has been used internationally for more than 20 years.
Hengli: mainly used in China 10 for many years.
affect
Both of them are botulinum toxin type A, and their working principles are the same. After excluding the factors of antibody production and dose size, the curative effect of the two drugs is equivalent.
price
Propofol is much more expensive than Hengli when injected at the same site.
Summary: Hengli has high cost performance; Because of 20 years of clinical experience, Botox is superior in safety and so on. Of course, it is more important to choose a regular medical institution for injection beauty than to choose drugs.
