Packaging mainly depends on whether the seal of the medicine bottle is complete. If it is open, it is best to refuse to use it.

2. Look at the characteristics of botulinum toxin

Domestic botulinum toxin can see white powder in the bottle, and imported botulinum toxin has a very small amount of white matter at the bottom of the bottle (similar to the dry trace left at the bottom of the cup after drinking milk). If it is a transparent liquid, it means that it has been used, and this biological preparation must be prepared now.

3. Look at the contents of the botulinum toxin package.

First of all, it depends on the production date and expiration date on the botulinum toxin package.

Secondly, domestic botulinum toxin depends on whether there is a "national medicine quasi-word"; Imported botulinum toxin depends on whether there is an "imported drug registration number" and so on. The main difference here is the authenticity of imported drugs. Many fake botulism are used as imported botulism. As long as it is an imported drug approved by the State Drug Administration, there must be instructions in both Chinese and English on the instructions and packaging, otherwise it is a fake.
