How often do you get Botox?

I get square jaw Botox and forehead and glabella Botox about once a year, or at most twice.

I haven't been getting Botox between my eyebrows lately, so wrinkles keep forming. I try not to frown, but I just can't help it. ㅠㅠㅠ

Botox is one thing, but what should I do to avoid frowning? Smiling with your mouth is the best method. That’s the best one I’ve found! Please share any other methods you know. I really want beautiful and firm skin. Haha.
