Your results from Dysport will gradually diminish over time, which is a great advantage when it comes to deciding how often you need to get treatments. After a few months, you'll start to notice that the small lines and wrinkles that were previously smoothed out will begin to reappear as the neuromodulator wears off. At this point, it's best to schedule another round of treatment. Botox results usually last between 2 and 6 months; the average result lasts about 3 to 4 months.
So why does Botox eventually stop working? The body is constantly producing new neurotransmitters, so the “blocking” effect of Botox gradually fades away as these chemicals start to circulate again in the body. The muscles are no longer inhibited. Once it activates, you have to wait for it to wear off or increase the results in some way (when possible). Botox and other anti-wrinkle injections (such as Xeomin and Dysport) work by limiting the movement of the muscles that cause wrinkles.
