It's been about two months since I received Botox for my square jaw at the hospital near my house. I was surprised that it ended faster than I expected. The waiting time was about 5 minutes? I think the actual procedure took less than 5 minutes and it seems to be a comfortable procedure. I am satisfied with both the treatment time and convenience, but the effect of the treatment is not great, perhaps because I have a lot of cheek fat. Still, it is better than no treatment at all, so I think it is worth giving it a light treatment at least once.
