Hi Debra. We usually use 30-60 units depending on how deep the lines are and how many of them there are. 45 is a good average. Good luck.
In general, 30-50 units of Dysport is adequate to improve the appearance of lines present on the forehead. However, this may vary depending on the patient. The amount of Dysport necessary to get the desired effect may depend on: 1) Severity of the lines that require correction 2) Time since previous treatment, if applicable 3) Any other circumstances unique to the patient I would recommend a consultation with an experienced physician, as he/she may be able to best assess your needs. Thanks and good luck!
