Dysport injections typically last between 3 to 4 months, depending on the individual and the treated area. Results can be noticeable after 1-2 weeks of injections. Factors such as metabolism, the severity of wrinkles, and the amount of the product used can influence the duration of the results. Like other botulinum toxin injections, Dysport temporarily relax the muscles, and its effects gradually wear off as the muscle activity returns​. For optimal and sustained results, maintenance treatments every few months are recommended.
