How much you should expect to pay for Botox in the UK is going to vary depending on the location and reputation of the clinic you decide to go with. Getting your injections at a clinic in Harley Street in London is guaranteed to be more expensive than getting your injections here at Earley Dental Practice in Reading. You should never hesitate to pay for quality care and service, but there is also no need to pay excessive amounts to get your Botox injections at a clinic just because of its street address.
