First experience with chin botox and salivary gland botox

Chin Botox is a priority. I was just thinking about doing something with the salivary glands, but after touching the chin, I was told that it wouldn't work for a chin like this, so I just matched the salivary glands and the outline... I didn't know, but there are some faces where the chin and salivary glands don't work because I don't know much about Botox. I thought all you had to do was just place a needle and the results would work... I highly recommend it as my salivary glands are very well developed. The irradiation is not enough so the next time I get it, it won't match the contour... The picture is just a botox mark. I don't know the type of botox, but it's okay. If you have it, please recommend it!
