Im a huge fan of botox, I have it. But it does give a certain "look"
I could instantly tell Izzy had recently had it done, she used to be frowny, and now she isnt.
I know Carla has it (and others maybe) but its not plausible that a couple in lousy jobs living in a shitty flat would fork out for botox.
Just think its a bit pants to be reminded that the characters are only actors!
