What should I compare besides the Ulthera price?

Since there is a price difference
The cheaper places caught my eye first.

But when I actually tried to make a decision
I'm wondering if it's okay to compare based solely on cost.

Medical staff or others performing the procedure
I think I need to check the consultation details and follow-up guidance as well.

Those who have received counseling at various places
What difference did you consider the most important?
