I need to get additional botox for my square jaw. How soon after should I get it done?

It's already been about 4 months since I got botox for my square jaw.

Lately I've been feeling like my muscles are starting to stand out again.

So I'm wondering how to schedule the next one.

I'm curious about how often you usually get it

. I'm being needlessly cautious because they say that if you get hit too often, you'll develop a tolerance.

I want the effects to last a long time, but I think it's important to adjust the cycle appropriately.

If you have any experience, please share your cycles or tips, it would be really helpful!
