Clostridium Botulinum There are seven different serotypes, with type A being the strain that produces the largest molecular size Neurotoxin.1-3 and works well Therefore, it is more commonly used in medicine than other species.

Botulinum toxin production methods vary by brand, depending on the bacterial strain used by each manufacturer.4 Including the production process of each manufacturer is different. As a result, the efficiency, safety, and action of each brand are different. therefore, the active dosages for therapeutic use cannot be compared. Therefore, the amount of anti-aging agents of each brand is recommended to be used in different dosages.

resistance BoNT / A

Because BoNT/A is a neurotoxin protein, which is a complex protein. It is obtained by extracting proteins from bacteria. which if in the production process cannot remove all contaminants Once it enters the body, it can stimulate the immune system to produce antibodies. May cause drug resistance In some people, it may trigger an immune response to BoNT/A, thereby reducing the response to the drug’s action.

The cause of this BoNT/A immunity depends on heredity. It also depends on the manufacture and formulation of BoNT/A. Therefore, the prevention of BoNT/A resistance depends on the choice of brand of drug.6-9

Causes of BoNT/A resistance10

  • Use drugs that have a non-standard manufacturing process.
  • Injecting too many doses at a time or injection too often
  • each person’s genetics
  • Injected by an inexperienced doctor or the injection is wrong, requiring more frequent injections.

Things to know before injecting

Before deciding to inject BoNT/A, the most important thing is Make sure that the medication you are injecting is of the highest quality. It has been in use for a long time.
