Thank you for submitting you concerns.Based on your information you have nothing to worry about because the results are not permanent. You will notice the changes within 3 to 4 months however it may vary either sooner or later that is just individual results. Best of luck. 

Unfortunately, Dysport injections cannot be reversed. The good news is, the results of Dysport are not permanent. It will wear off on its own within 3-4 months.
