For those of you who have received 600 shots of Density, how were the results?

Lately, my jawline seems to have become less defined than before, so I am looking into Denserty.
It’s not like my face feels saggy overall, but it definitely shows in photos.
I am especially concerned about my deep cheeks and jawline.
I don't have much cheek fat, so I'm also worried about receiving it too strongly.
The hospital recommended about 600 shots, but I'm wondering if that's the right amount.
I am also curious if there is actually a big difference between 300 shots and 600 shots.
I'm also curious if having a lot of shots necessarily means it's effective.
If anyone has tried the Density 600 shots, I would like to hear how effective they were.
I am also curious if the effects became more apparent over time compared to immediately after the procedure.
I would also appreciate it if you could let me know how many weeks it took to see proper results.
I am also curious about the satisfaction level of those who have received treatment for mild sagging like me.
