What type of Botox is usually used for the procedure?

Botox is the most commonly administered injection, but

I noticed that every hospital has a huge variety of medications.

I usually get the Botox on sale or choose what the clinic recommends.

I just did it, so I didn't really pay much attention to it.

There are domestic and foreign products... I'm wondering if there is a significant difference between them.

I'm curious if the difference in effect is significant or similar.
