Is there anything I absolutely need to check when receiving counseling?

I am confused because the explanations for Ulthera vary slightly from hospital to hospital while I am researching it.

Even though it is the same procedure, the price difference was bigger than I expected.

I'm not sure if simply comparing the number of shots is enough.

I heard that the required energy or depth may vary depending on the area of ​​the face.

What else should I check besides whether the equipment is genuine when consulting?

Since it is my first time getting this procedure, I am worried that I might miss something.

I would like to hear advice from those who have actually received counseling at various places.
