Lez, I've not had Botox but I know a lot of people who have, I can't stress enough the importance of researching your surgeon/practitioner carefully before you go for it.
Get loads of recommendation and referals, and research it!
I have considered it myself, but chickened out. It's a treatment that needs keeping up to date, maybe every year or more often. I know it can go wrong. I would be afraid of getting the surprised look permanently. I do know people that have been really pleased with the results though. It paralyses the muscles apparently, starts to have an effect about 10 days after treatment.
Thanks guys, i did know the couple were going to be on GMTV but i missed it.I think i`m probably to chicken to have it done but i will research it carefully if i do.
