How long does botox last for

How long does Botox last for? If I had it done on 16th Nov, when would I need next appointment?

I can still wrinkle up my forehead after three days. Do I need to have more or will it take longer?

Botox

it lasts 4-6 months, but you can get re-touches i think? there's a useful article in the Beauty section
