Does Density work better the more shots you take?

As I looked into the procedure, it seems that the number of shots recommended varies slightly from hospital to hospital.

Even though it is the same face, some places talk about fewer shots.
I hear that other places recommend more shots, so I am curious what the criteria are.

Is it necessarily a good thing to receive a lot?
I would like to check if the appropriate amount varies depending on skin condition or face size.

For those who have received Density, I would appreciate it if you could share your experience on how you decided on the number of shots during the consultation.
