When getting Botox for the first time, should I choose a domestic or imported product?

I'm looking into Botox, but it's harder to decide than I thought because the products vary from hospital to hospital.

Since there is a price difference, I wonder if I should unconditionally choose the cheaper one,
That said, I don't think there is any guarantee that expensive products suit me better.

For those trying it for the first time, what criteria did you use to select the product? I'm curious if there are any specific points that must be compared during the consultation.
