...absolutely fine and over and done with in a jiffy 
Yes it was slightly uncomfortable and I did flinch as it was done (a kind of uncontrollable reaction) but it was most definitely bearable. I had my cheeks and chin done and although it left me extra red afterwards it has calmed right down now.
I really hope the results are good, apparently it could be a few weeks until I´ll see any difference. I have another session booked for October.
The point of my post is just to say that if you are thinking of having it done then my advice is to "go for it"!!!
