Has anyone tried getting Botox around their mouths?

I am constantly bothered by the wrinkles around my mouth whether I smile or just sitting still, so I am considering getting Botox for my mouth.

As I get older, I feel like the corners of my mouth are drooping a bit, and I think my impression looks a bit gloomy due to my chin and fine wrinkles around my mouth. I’ve heard a lot about jaw Botox, but I’ve also heard that if the muscles around the mouth are manipulated incorrectly, it can make my mouth shape look awkward when I smile or my facial expression look unnatural, so I can’t easily make up my mind.

I am especially worried about whether there is any discomfort when eating or speaking, or if there are any side effects such as drooling or difficulty closing the mouth.

Has anyone had Botox injected into the corners or edges of their mouths? I would appreciate it if you could share your experiences regarding whether the results are truly satisfactory and how long the awkwardness in facial expressions lasts.
