Does resistance develop if I get Botox frequently?

I've become interested in Botox, so I'm looking up various things.

However, I saw a post saying that the effect decreases if you get hit repeatedly.

I am curious if there are really cases where resistance develops.

If so, I would also like to know how often I should get vaccinated.

For those receiving the procedure for the first time, this is the part they are most worried about.

It seems the duration of the effect also varies greatly from person to person.

I don't think getting hit often is necessarily a good thing.

I would like to hear opinions from those with experience.
