I visited for cosmetic and teeth-grinding prevention because I grind my teeth badly in my sleep. I had already gotten jaw Botox about three times, so I mentioned that during the consultation, and they said domestic Botox can develop resistance and may not work well, so I got foreign Botox instead. I could definitely feel that the teeth grinding had decreased.
But for cosmetic purposes, I honestly do not think Botox creates a very noticeable change, so I am not really sure.
