A patient may notice the desired effect within 2 days, with peak-effect around 10-14 days after treatment. However, the results vary. Typically, it may last for 3-6 months, sometimes adding up to 12 months, depending on which areas are being treated and how much medication was applied. However, the results of a Dysport treatment are not immediate. Results begin to appear 3-5 days after the injections, with maximum results taking up to two weeks.
