Juvederm ultra plus XC contain 2 pack of 1ml in a box. is it correct?

You are correct that this product contains two syringes per box.  However, most doctors charge per syringe, not per box of the product.  Unless you specifically paid for two syringes worth of Juvederm the doctor only would have injected one of the syringes in the box, and saved the other unopened syringe for another patient.  They are in completely separate packages within the box.

Juvederm Ultra Plus XC comes in a box with two individual 1 cc syringes.  We charge by the syringe, not by the box.  Most patients only require one syringe.  Each syringe typically costs $600.

Allergan packages Juvederm with 2 syringes in each box. If the box has fewer than 2 syringes than the Juvederm may have come from overseas or restylane which is packaged in boxes with 1 syringe may have been used instead.
