Dysport and Botox are both neuromodulators used to temporarily improve the look of wrinkles. While they are similar, there are some critical differences between the two.  One significant difference is that Dysport typically requires fewer units to achieve the desired results. In general, you will need about 50% fewer units of Dysport than you would Botox.  Dysport tends to work more quickly than Botox, so you may see results in as little as 24 hours after your treatment.  However, both neuromodulators typically last for about 3-4 months before further treatments are necessary. This means that treatment with Dysport can often be more affordable than one with Botox.
