How many shots of Shrink do I need to see good results?

I'm thinking of getting Shrink again after a long time, but I'm debating the number of shots. I used to get about 300 shots, but this time I want to focus on intensive care for my double chin and jawline.

I am debating whether 300 shots will be enough or if I should increase it to 400 or more shots.

I'm curious how many shots you usually use when focusing on the jawline or cheeks!
