How much do Brits pay for Botox

[claredavidson]

I just left a message on another thread about Botox i.e. how many years I've had it and how long it lasts, and it occurred to me that I wondered how much people pay in the UK?

£200 for forehead and crows feet - 2 areas although he does stick a tiny bit in my 11s so it's technically 2.5 areas

£120 for one area from my dentist. Think another £20-30 for additional areas but I only ever get my elevenses done.
Top ups-I've been getting Botox for almost 20 years with loads of different practitioners and each and every one has given a top up at 2 weeks. They often inject a little less initially than they think you'll need to avoid the frozen look then when they review at two weeks they can inject a little more if required.
