Since it was my first time, I just got the cheapest one instead of the expensive one, but
since I suffer from bruxism, I was half-hearted and got both temporalis muscle and chin botox.
But I don't know much about bruxism, and maybe because I gained weight, it didn't have any effect on making me look slimmer. Haha.
Next time, I'll just get it done for the chin. Still, I recommend anyone who bruxism to try it once.
