Will there be any difference in the effect of injecting botulinum toxin in different hospitals?

1 The lower the injection dose, the lower the concentration and the shorter the aging time, so the time of re-injection must be advanced. 2 Different brands of Botox have different aging effects. Botulinum toxin with the same concentration and dose is injected directly into muscle, and the action time is much longer than that of only partial injection into muscle and partial injection into subcutaneous tissue. Therefore, the technical difference of doctors' injection directly affects the length of drug effect.
