Botox, Dysport, or Jeuveau are injected during an office visit that lasts approximately 20 minutes. You will begin to see the results of the injections in 2 to 5 days. First, you will notice that your muscle is not responding the way it used to, and over time, you will notice the wrinkles associated with that/those muscle(s) become smoother. The smoothing effect will fade after about 3-4 months at which time you will return to your baseline.
