I went to get Botox only for my chin, but was told that my salivary glands were too big and that it would only be effective if I got Botox on my jaw joint. This was the first time I learned that there was a separate Botox for the temporomandibular joint. Since the temporomandibular joint and salivary glands go into special areas, there was no discount. The jaw, salivary glands, and temporomandibular joints were hit like this, and it definitely had a facial reduction effect. I plan to get it again in 4 to 6 months, and will continue to manage it consistently. If you feel like your chin is protruding even after getting the contour right, we recommend temporomandibular joint botox and chin botox together!! (I explained that the salivary gland treatment may not be effective at first and that if it is not effective, it is recommended to get the treatment again in a month, but I am not really sure yet, so I am thinking of having the treatment again in a month)
