Typically you will see results as early as 3 days, but more likely between 5-7 days post-injection.  Full, optimal results usually take up to 14 days to appear. So make sure if you have an event coming up that you want to look your best for, you schedule your appointment at least 2 weeks in advance. Results can last up to 3-6 months depending on how your body responds to the neurotoxin.  Results will vary from person to person.
