Does getting Botox frequently cause resistance?

I am considering getting Botox regularly, but I have one question.

I have heard that getting Botox multiple times can cause the body to develop resistance, leading to a gradual decrease in effectiveness. On the other hand, I have also heard that there is no need to worry as long as the proper intervals are maintained, so I am wondering which is correct.

I would like to know the typical interval of months for the treatment and whether there is a real possibility that the effectiveness will diminish if administered at too short intervals. I am also curious if it is possible to maintain similar results to the initial treatment even if I continue to receive treatment on the same area.

I would like to hear from those who have actually experienced this, specifically regarding whether the Botox effect is almost non-existent or if the duration of the effect is simply shortened if resistance develops. I am also curious if switching to a different product type would be helpful.
