I've tried it twice on my face. The first time was with a company called Lasique in Austin Texas. I had a treatment a month for 14 months and it failed completely. That was over 10 years ago and I recently decided to try again after meeting several people if HAD worked for. I'm going to the Hall Rejuvenation Center in Austin and have had my third treatment now and it is working VERY well.
The thing is, many places buy one laser machine to do it all - the dermal ablation, blood veins, wrinkles, etc. When it comes time to kill hair, they put a different attachment on it - and it doesn't work for squat. The place I'm using now has a machine called the Candela Gentle LASE Plus. It was designed for one thing - killing hair and it works great!
It DOES hurt. I suspect it hurts because in my case it was a heavy beard and the skin on your face is more sensitive than other places would be. I would imagine that with the thinner hair a woman has it might be less painful but have no way to know that for sure.
The ideal candidate has fair skin with dark hair. That is because the dark pigment in the hair absorbs the laser energy and is killed. The laser will NOT kill light colored hair.
I really HATE the thought of posting this on a forum dedicated to beauty as the pictures are UGLY, but having just gone through the agony of trying to decide if I should spend the money on this myself, I would like to help ease your mind.

If you can get past the "ewww, he's ugly" reflex and look at the results, I think you will find they are significant.
