Dysport comes in 300 unit sterile vials in powder form. Each clinic has to add saline to the vial to reconstitute or dilute the powder. Anywhere from 1cc, 1.5cc, 2.5cc to 3cc or more of saline (salt water) can be added per 300 units. It is important to know how many units of Dysport or Botox are being injected because the volume depends on the dilution and unless you know your doctor’s dilution ratio, knowing how much volume was injected is not useful. B Medical Spa always tell their patients exactly how many units or the dose of their injection.
