Satisfaction with Botox when getting regular injections

How satisfied are people with Botox when getting injections continuously?
I would like to hear stories from those who have received multiple Botox injections for their square jaw.

I am curious about how the feeling changes from when I first got it compared to when I consistently manage it for 1 to 2 years or more, and how long-term satisfaction with Botox differs.

I am concerned about long-term satisfaction with Botox because I have heard that resistance develops or the effects gradually diminish.

I would appreciate your feedback on whether the satisfaction with Botox remains consistent relative to the cost when receiving it regularly, or if you end up switching to other procedures.

I would appreciate it if you could give me some practical advice on how to schedule my treatment cycle to maximize satisfaction with Botox.
