Dysport is reconstituted as a solution. In a given treatment session, any number of areas might be treated. Note that not all facial issues can be treated with botulinum toxin. Dysport like BOTOX is excellent for periocular issues. The lower face is much better addressed with fillers treatments like Restylane.
Greetings~ You can have multiple areas treated during one session or office visit. Most patients do a few areas at once. (for example: Crows feet, Glabella (between the brows), and Forehead) Some offices charge by the unit, so you pay for the amount injected regardless of where the Dysport is placed. Other offices charge by the area or for a standard amount. If they charge for a standard amount, it is up to you where you want the Dysport but if you put inadequate amounts in a number of areas you won't be happy with the results or the longevity Good luck~ Dr. Grant Stevens
