Did you feel that the doctor's skill is more important than the number of shots with Ultherapy?

I am asking this question because I am curious about those who have actually received Ulthera. While researching clinics, I noticed that even for the same Ulthera, the number of shots varies greatly—such as 300, 400, or 600—and the price differences are quite significant. So, I am wondering if it is right to simply choose a place with the most shots.

For those who have actually received the treatment, did you feel that the practitioner's experience or design was more important than the number of shots? I am also curious if there were differences in results even with the same 300 to 400 shots, depending on which area was treated and at what depth.

I understand that the necessary areas and depths vary depending on facial shape, skin thickness, and fat volume, so I would like to know if it was good to choose a place that thoroughly checked these factors during the consultation. I heard that since Ultherapy allows you to check skin layers while viewing real-time ultrasound images and select depths such as 1.5mm, 3.0mm, and 4.5mm, it is difficult to simply compare numbers.
