I received botox twice on my calves and once on my chin.
I think I saw a lot of effect on my calves and chin.
The calves use a lot of muscles, so after a while, the muscles build up again.
Still, I don't think I'll go back to when it didn't fit.
The chin seems to work faster than I thought. I don't think it's been 6 months yet, but I don't care so much that I don't think I have to get hit again.
