Is there a significant difference in results depending on the doctor when getting Ultherapy?

I’ve decided to get Ulthera, but choosing a clinic is the hardest part. It seems they use the same genuine equipment, but the prices vary quite a bit from clinic to clinic. I’ve heard that the doctor’s experience and the design tailored to my facial structure are also important. Even if the same equipment is used, will the results actually vary significantly depending on the practitioner? I also think I should check if the director personally examines my facial condition during the consultation. I’m curious whether they focus on specific areas or proceed in a balanced manner overall. Is there anything I absolutely must check when choosing a clinic? I’d like to know if there are any additional factors to look for besides genuine tips and the number of shots. I’m debating whether it would be better to choose a place with a lot of experience, even if it costs a little more. For those of you who were satisfied with your clinic choice, what criteria did you use to make your decision?
