No one really knows the long term effects of botox. It is after all a poison. Imagine a tv show back in the 60s or 70s similar to Tomorrow's World, telling us that in the future, people will be injecting their faces with one of the most toxic substances known to man. Science fiction? no reality.
That's a good point. Well done, not over the top botox seems like a great invention now, but who knows what could happen long term.
