Dysport is very similar to Botox® Cosmetic. They are both from the same drug family, Abobotulinum Toxin A. However, there are some differences. Dysport can be more cost effective as the cost per unit is less; though, Dysport requires more units per treatment. Clinical studies have also shown visible results within 24-48 hours; versus Botox which can take from 3-7 days. There is also evidence that Dysport injections may be more effective with large muscle groups.
