If I stop getting Botox, will I return to my previous state?

As I get older, I'm getting a lot of wrinkles here and there, so I'm planning to get Botox. The wrinkles between my eyebrows are what bother me the most, so I'm planning to start there.

I suppose getting Botox would alleviate or make deep wrinkles disappear.

By the way, if I stop getting Botox, will my wrinkles return to the exact same state as before? I am curious whether they completely revert to their previous condition or if the slightly improved state is maintained once I stop the injections.
