Thank you for your question. Some muscles respond quicker than others. The larger muscles can take longer or if some areas are just treated to minimize and not freeze the movement, the rate of inactivity can seem different. We use 2 weeks as an evaluation time. I hope this helps.
Is It Possible for Dysport to Work in One Area and Take Longer for the Other?

Differential onset and duration of action for Dysport in different facial muscles
Yes, it is possible for Dysport to begin taking effect sooner in some areas than others. Dysport acts to relax muscles, and the dosage needed to cause relaxation differs depending on the size and strength of the target muscle.
How long does Dysport take to work
It can take 7-10 days for the full effects of a neuromodulator like Dysport to work. Yes, it can work faster in some muscles rather than others. So wait for 7-10 days for the full effects to take place, in all muscles, and then be seen by your injector if you still have movement you weren't expecting.
