One of my friends who's had it, has had it done well (botox and filler) and she can still frown, her face is full of expression and she looks exactly how I always picture in my mind's eye - which is 15 years younger than she is now - but she does look a bit odd without her glowy makeup (she is the first to admit it) and won't be getting it topped up. She has a very tiny amount, and it was done by a very good practitioner. Saying that, I still wouldn't have the procedure, the cost is too great.
Another mate has become a little addicted and is starting to look ridiculus. She has virtually no movement in her face at all, is VERY shiny, and though it has smoothed out the wrinkles she loathed most it draws attention to the ones no one would ever have noticed before. She's a lovely person, beautiful looking, but is so addicted to botox, filler, fake tan etc that she has gone beyond looking good. It's a real shame actually, because she's turning herself into this weird looking person with no visible personality... but it's her choice. She knows my opinion and doesn't give a shit, which is her absolute right.
I would never say never to procedures that could refresh me, if I had the money, but I am very wary of how addictive they can be and how they can sometime draw attention to otherwise perfectly fine areas!
I would never get Botox though.
